Turnkey PCB Assembly

Choosing turnkey printed circuit board assembly is a great solution for any business. With this option, our professionals will gather all necessary parts and components as well as assemble the PCB. This PCB assembly solution is cost-effective and helps save time as we will ensure we have everything we need for the proper build.

Kitted/Consigned PCB Assembly

For those who know exactly what they want in their PCB, but perhaps don’t have the time or equipment to assemble, kitted printed circuit board assembly is a perfect choice. You can purchase all of the components and parts you want and need, and our experts will use each when assembling the PCB. This can help you have better control of production costs and know what to expect with the completed printed circuit board.

Combo PCB Assembly

Perhaps you have a few components you know you want to use in your PCB, but still need some parts to complete your PCB electromechanical assembly – that’s where combo PCB assembly comes in. You supply us with the parts and components you have, and we’ll supply anything you still may need, and professionally assemble it all together. This option still allows you to have some control of the production costs, as well as control over your most important components combined with the ease and time-saving capabilities of the Advanced Circuits team completing the work.

The PCB assembly process is critical to get right the first time. A single misstep here could result in malfunctions, lack of functionality, or even the threat of accidents. In this post, we’ll cover some of the most important PCB assembly process steps and what you should know.

It’s Not Board Manufacturing

First and foremost, understand that the PCB assembly process takes place during a specific time in the development of an electronic device. It’s not about manufacturing – that happens first. For instance, at Advanced Circuits, we’ll manufacture the board itself, including all the required layers, creating the traces, and all the other important steps, and then work on PCB assembly.

In short, PCB assembly is the process of bringing everything together into one place and creating something functional out of multiple components. It’s taking that newly manufactured board, adding components and resistors, and then making sure it does what it is intended to do.

Understand the PCB Assembly Technologies

Assembling a printed circuit board requires more than just the raw components and a well-designed board. It also requires the right technology. In this case, there are several options to choose from, and each brings something different to the table. For instance, there’s surface mount technology (SMT), as well as manual soldering, and the use of pick and place machines.

While some PCB assembly processes will require just one technology, others will require a combination of two or more technologies. For example, many boards require the combination of through-hole technology (THT) and surface mount technology. Understanding when, where, and how to integrate those technologies is a critical consideration when choosing a company to handle your project or production.

It’s also important to understand that the PCB assembly steps involved with the various technologies differ, as well. Below, we’ve outlined some basic steps involved, as well as how they differ from technology to technology.

The PCB Assembly Process: An Overview

• Solder Paste: If you’re following a traditional PCB assembly process, the first step is the application of solder paste. Note that this is not the case with THT, but SMT does require paste application and/or printing.

• Component Placement: In the traditional PCB assembly process, the next step is to place the components on the board. This can be done manually, or it can be done with the assistance of machinery (pick and place systems). In THT assembly, components are placed by hand, which requires incredible precision. In the SMT process, robotic systems place components on the board. Note that automated placement is far faster than manual placement and is just as precise.

• Reflow: In the traditional PCB assembly process, the next step is reflow, which is when the solder is first melted and then resolidified. The board and all its components move through an oven, which heats the solder, liquifying it and ensuring that connections are formed before the board moves into a cooler, where the solder is cooled.

Note that the THT process does not require reflowing solder. Instead, the second step here is to inspect the board and rectify component placement. This is due to the manual placement process – a visual inspection in conjunction with a design transport frame helps ensure placement accuracy.

In the SMT process, reflow soldering takes place at this time, as well. The board is sent through a furnace, which melts the solder paste, allowing it to flow as necessary, before the board passes through a series of coolers that gradually bring the temperature down, solidifying the solder on the board and cementing the components in place.

• Inspection: The next step in the traditional PCB assembly process is a visual inspection of the board, soldering, and components. Note that this step has already occurred in the THT and SMT processes.

• Through-Hole Part Insertion: The traditional process requires that through-hole insertion be done manually, after the reflow and inspection process. Soldering is also often done manually, but it may be done using wave soldering.

Wave soldering occurs during the THT process at this point, as well. The entire board moves over liquid solder and then moves through coolers to solidify the solder.

Note that there is no correlating step in the SMT process (it is actually already finished, and wrapped up after just three steps, although a visual inspection should still be conducted to ensure accuracy and to reduce the potential for errors).

• Final Inspection and Cleaning: The final step in the traditional PCB assembly process is a final inspection of the board, the solder points, and the components, and a cleaning to ensure that debris or excess solder is removed.

The Right PCB Assembly Process for You

While the SMT assembly process is faster and often more accurate than either the traditional PCB assembly process or the THT process, it is not always the best option. For instance, if you only need a single prototype board assembled, the THT method might be the better choice. Each situation varies and there is no single solution that will always work for every need.

At Advanced Circuits, we understand that needs, budgets, and goals vary. We pride ourselves on offering exactly the solutions each client needs. Whether you’re producing a single prototype for proof of concept needs or you’re ready to move into full production with thousands of units being produced, we can help. Contact us today to schedule your consultation or to learn more about our services and capabilities.

They should get quality work with a quick turnaround time while having someone they can talk to who helps ensure they stay competitive against other companies. However, knowing what they need from the PCBs for their circuit designs doesn’t always mean it’s easy to immediately find the right company to step into their corner. We’ll share a few tips to make that process easier.

Know the Right Questions That Should Be Asked

When a person chooses someone to create their PCBs, it’s essential to ask them questions to be sure they can handle their needs. Sometimes the answers to the questions can be found on company websites and reviews. Other times individuals might need to contact the company on their own and ask the questions that are important to them. Having answers will provide peace of mind that they’re choosing the right company for their needs.

How Much Experience Does the Company Have?

Experience is important for any product or service that someone chooses to pay for, whether that’s a car repair or PCBs to fit their circuit designs. When it comes to printed circuit boards, a manufacturer’s experience is essential to ensure customers get boards that are right for their needs. Knowing how much experience a company has will give insight into how many resources they have and what amount of knowledge is available. It also shows competence if a PCB company has been in business for a long time. That means they have adapted to the times and continuously put out great products.

What Certifications Does the Company Have?

This is another question that can speak to how qualified a company is with PCBs for a person’s circuit design. Certifications typically require a third party to verify that the company complies with certain standards or requirements. For example, IPC creates standards with regards to PCBs and industries related to electronics manufacturing. Any company someone decides to work with should be capable of meeting the standard required by their products and industry. This includes broad regulations as well as those that apply only to their industry. The best choice is a company that has experience working with other people in the same industry.

How Does the Company Stand Out?

This might seem like a broad question that could have any number of answers, but it can help people narrow down the right business to help with their product. This is especially the case when they have a few options for companies that offer all the services and products that they need. This question can be as simple as asking what makes the business different from others or can delve into what value-added services are provided. For example, Advanced Circuits can help with their circuit designs by providing free PCB design and file check software which will save customers money and time.

Important Considerations When Choosing a PCB Company

The reality is that there are tons of companies that provide PCBs and many of them also have services to assemble and create circuit boards that match specific needs. This can make it a challenge to choose between them since some companies may appear to be quite similar. However, there are a few things people can look at early in the search to get a grasp on which company may best fit their needs.

Types of Products Provided

The first thing for people to check is what products are offered by a company to be sure they even provide what is needed. If the company specializes in the needed products, that’s even better. Once they know the products exist, they can find out more about the pricing and quality of the products.

For instance, what kind of PCBs are available? These can range from rigid to flexible and rigid-flex. They might be metal core, aluminum backed, or hybrid board. People can ask about which substrates are used in the board. They can also look into the quality and consider the prices and how they stack up to the competitors. All of these things can help with the decision.

Services Available

In addition to products, people should consider services that they might need. If the company offers everything they need, they won’t have to go between businesses to get their product ready. Some of the services that should be considered are:

• Prototyping – Ability to create prototype PCBs before moving into production so customers can reduce costs and timeframe through thorough testing.

• Layout and Design Services – These can speed up their production by offering a complete design or providing software to make someone’s own designs.

• File Review – File reviews can help by ensuring a design is free of errors and that the company has all of the needed components to start creating its PCBs.

• SMT Prototype Stencils – Stencils are laser cut and made of stainless steel foil to ensure the solder is placed in the right areas of the PCB. The stencil helps with accurate circuit designs.

Other services that can be helpful include DXF to Gerber conversion, panelization, and PCB design for manufacturing services.

Accessible Capabilities

It’s also important to be sure the company is capable of offering what is needed for a customer’s PCBs. This includes everything from being capable of handling the size of their order to having a certain lead time and offering the right layers on a PCB. Other things to consider are the surface finish options available, the via options, specs and tolerances, and other things that they prioritize with their circuit designs. It might take some time to get answers to all these things, but once someone does, they will know whether a company is right for them.

Advanced Circuits is the third-largest manufacturer of printed circuit boards in the United States and offers excellent customer service and reliability. The company also offers a variety of services to customers like free PCB layout software (PCB Artist) and a free PCB file check. Those who want a streamlined PCB company in their corner can get in touch with us to learn more.

This is a type of technology called surface mount technology or SMT. Almost all of the equipment manufactured commercially today uses this innovative technology. Surface mount technology has huge advantages when manufacturing printed circuit boards (PCBs). Because the components on SMT boards are so small, it also lets people pack more electronics into a small space.

What Surface Mount Technology is All About

The 1970s and 80s were a time when automation started to take off for printed circuit boards used in all sorts of equipment. Traditional components using leads weren’t easy to use with PCB assembly. For capacitors and resistors, the leads had to be pre-formed to fit through holds and integrated circuits had to have leads set at a specific pitch to go through holes quickly and easily.

This led to difficulty since many of the leads would miss the holes because the holes were quite tight. Because of that, an operator would need to step in and resolve the problems to make the components fit. This meant a loss of time and money since the machines automating the process had to be stopped.

Printed circuit boards remove the need for leads to go through the board. Instead, components could be soldered right to the board. This led to the birth of SMT and the use of components for SMT has risen quickly because of its many advantages. Nowadays, surface mount technology is the primary option for assembling PCBs in electronics manufacturing. The products made can be small and used in many different ways.

Why Surface Mount Technology is Favored in Design

While the primary reason for moving to surface mount technology was related to cost, speed, and reliability, there are other benefits. This technology has had a huge impact on the way that people today design and develop new circuits and equipment. The good thing about this is that the change has largely created advantages rather than disadvantages. Some things to be aware of for developers using surface mount technology are listed below.

• Circuits Are Smaller and Denser Than Ever – The electronics industry has always had the drive to offer more function in smaller packages, but that was never an easy task before surface mount technology became widespread. SMT is designed to make this simple since everything is in a miniature format. Components can be extremely small and mounted closer together on the circuit board than would ever be possible with typical components with leads. This, combined with the better functionality available through integrated circuits, makes life easier for a development engineer.
• Lower Power Rating Requirements – One of the most important things to look for when designing and producing electronics is the power rating of the components. With surface mount technology, devices can have lower power ratings than ever before. As an example, a standard resistor with a lead can dissipate 0.25 watts or even more. However, surface mount resistors are smaller so the dissipation is also lower. People should be aware of this during a build but always make sure to check the manufacturer’s data for the exact numbers.
• Less Inductance and Spurious Capacitance – Since surface mount technology components are smaller, that also means that spurious inductance and capacitance are also going to be smaller. An SMT resistor, to keep with the previous example, will be closer to an ideal resistor than a resistor with leads. In the same way, a surface mount technology capacitor is going to create less parasitic inductance. When taking this all together, standard SMT components will have higher frequencies and faster speeds than leaded components are capable of.

Using Surface Mount Technology with Printed Circuit Board Assembly

Nowadays, SMT is used in almost all facets of PCB manufacturing and assembly. More electronics can be placed in a smaller space using the technology. All of the components are smaller and many of them offer better performance than traditional components. They also can be easily used with automated machines to eliminate the need for worker intervention during the assembly process.

With wired components, it was always a challenge to rely on automatic placement. All wires had to be pre-made to fit the correct hole spacing and, in some cases, there were still issues with placement. PCB assembly typically has all components placed automatically. Manual assistance might be occasionally needed but it is rare. High-quality circuit boards reduce the need for this to the point of even changing a design so components fit perfectly.

One issue that used to be common with surface board technology components was their lack of resistance to heat. Since the components are soldered in, this raises the temperature of the part and could cause issues in some situations. However, new components have been developed that have no problem tolerating the temperatures associated with the soldering process.

SMT Components and Devices

Surface mount components differ from leaded components since they are set into a board and soldered to it rather than wiring between two points. The leads don’t go through holes as might be expected of traditional components. There are three package styles used for SMT components: transistors and diodes, integrated circuits, and passive components. Many passive components consist of resistors and capacitors in standard sizes with typical package sizes. Transistors and diodes often come in a small plastic package, while there are many package options for integrated circuits.

Any business creating a project using printed circuit boards should consider the ease and convenience of surface mount technology. At Advanced Circuits, we offer printed circuit boards that are high-quality and ready for this kind of technology. We also provide assembly and manufacturing services to save people time and money. Regardless of the size of a business or how large their circuit board order is, we’d love to help. Get in touch and find out more about what options we offer.

Know Your Goals with the Printed Circuit Board

Before you start to design the PCB and long before it can go through the circuit board assembly process, you need to be sure that you know what the board needs to accomplish. Different types of boards may have different functions. Some might be relatively simple, while others may need to handle more functions. Those who have complex needs from their boards will likely need to use multilayer PCBs. This will allow for more functionality in less space.

Take the time to determine what the goals are for the board before beginning the design. Designers will find that having a solid plan in place even before heading to the software will help to keep them on the right track.

Sometimes, the design that you create will not work as intended. It’s always better to find this out in the early planning and designing phase rather than when the boards are being printed. Take the time needed to perfect the design. A good plan and the right software will help with this.

Use Quality Software

When designing the boards, you will want to be sure that you are using quality software that is made specifically for PCBs. Good software can help to make the process of designing easier, and some programs will even offer the ability to check the files before they move to the circuit board assembly process. They can find errors, and some software can fix certain errors to make your work easier.

If there are potential problems with the design, you can go back into the software and make the needed adjustments before you move to the process of circuit board assembly. This helps you save time since you won’t have ordered a prototype that doesn’t work and then try to figure out why. Once you are certain that your board is in good shape, you can then get a prototype or have a large number of the boards manufactured.

Generally, you will want to have prototypes done first. Order just a single board, or a few, and test them out. See how they work, how they stand up to different situations, etc. This will let you know if you need to do any further design work before moving into the manufacture and circuit board assembly phase.

Of course, many will worry that prototypes will be difficult to get because some manufacturers do not want small orders. When you work with Advanced Circuits, you will not have to worry about this since there are no minimum orders. We also provide an engineering check to ensure it will work, and you can use our free software to design the boards.

Hire a Professional for Manufacturing and Assembly

After you are certain that you have a circuit board with a good and usable design, it is time to assemble the boards. However, you may not want to attempt this on your own. Consider just how much time and space it will take to perform circuit board assembly, even for a few hundred boards. If you have thousands, it will be next to impossible for you to do on your own unless you already have a facility dedicated to production.

This is not the case with most designers, so it makes more sense from a logistical and financial perspective to work with professionals like Advanced Circuits. If you were to try to set up an assembly facility of your own, you would need to have additional space and likely additional employees. Also, there would not be a guarantee that the circuits were working properly.

You need to have a manufacturer that has the space, expertise, and tools available to manufacture the circuit boards. Outsourcing the circuit board assembly is typically the best option. Of course, you can’t entrust your boards to just any manufacturer.

Why You Should Work with Advanced Circuits

High-Quality Materials and Assembly

When working with a professional company for printed circuit board assembly, they will typically be using the best possible materials and assembly tools for the job. While this may not be true of all companies offering these services, the reputable companies that have been around for a while will. Choosing a company that can offer the best materials and that provides topnotch assembly services helps to ensure that the final product is perfect.

Naturally, you want to be sure that the circuit boards you are using are the best quality they can be before you start to use them or sell them. Choosing professionals rather than trying to assemble them on your own, in-house, will help to ensure this.

Find Errors Early

Even those who have been designing printed circuit boards for years can make mistakes during their design. A mistake that is followed for all of the circuit boards that are constructed would mean a huge error that could cost your company a lot of money. Rather than letting this happen, you could be working with a professional for the printed circuit board assembly.

At Advanced Circuits, for example, we have engineers test the design – even after you have tested it – just to be sure that there are no issues that could crop up down the line. This provides you with the peace of mind you need to go ahead with the full assembly. You will know that the boards will work properly once they have been assembled.

The software that is available through our company is free, and it can do more than just help you design a circuit. It helps to make it easier and reduces the risk of errors. When the boards are submitted, we will check to ensure that they have been designed correctly. The earlier the errors are detected, the better. It means that you can fix those problems before you go into full manufacturing mode.

Save Time

Consider how much time you would be spending if you had to manufacture and assemble all of the PCBs at your own facility. You would need to hire extra people just to keep up with the manufacturing and assembly needs. It would take up a lot of time that could better be spent working on other aspects of your company. It makes far more sense to hire professionals for the printed circuit board assembly. They can take care of the assembly, whether you need one PCB or you are in the market for thousands of boards.

Reduced Manufacturing Costs

Additionally, consider the manufacturing costs that you would have to incur if you assembled the boards on your own. You would need to have a large space available for the printed circuit board assembly. You would have buy all of the materials and tools needed, and more. You would likely be spending far more money than if you had just hired a professional company to take care of the assembly of the boards for you.

You can talk with companies like Advanced Circuits to get an estimate of how much it will cost for the PCBs that are needed. When you compare this with the cost of increasing the size of your facility and hiring more people for the printed circuit board assembly, you will see why outsourcing is such a good idea.

Turnaround Time Can Be Fast

One of the reasons that some companies still consider in-house printed circuit board assembly is because they worry that another company won’t be able to help them meet their deadlines. This is not necessarily true. When you choose a company that is known for having a fast turnaround time, you can get the boards in a matter of days in many cases. Of course, it will depend on just how many of the PCBs are needed and the company you choose for assembly.

Shipped Directly to You

Once the printed circuit board assembly has been completed, the manufacturer can have them shipped right to your door. The shipping time can vary, but when you choose a quality manufacturer like Advanced Circuits, it tends to be fast. This means you will be getting the circuit boards you need quickly.

Choose Advanced Circuits for PCB Needs

Naturally, you will want to be sure that you are choosing only the best for your printed circuit board assembly. You should take the time to consider just what the company offers, along with how fast they will be able to provide you with the completed boards. Price, of course, is another factor. You want to choose a good company that remains affordable and that can provide quality customer service.

Now that you know more about the benefits that are associated with using a professional for printed circuit board assembly, it’s time to find a company that can provide you with what you need. At Advanced Circuits, we strive to provide our customers with the best service and products from start to finish.

Whether you simply need a prototype, you have a short run that you need, or you are looking for a substantial number of boards, we can help. Get in touch with us today.

Why should turnkey PCB assembly be a challenge? There are many steps involved. Just consider a few of them:

• Initial design
• Output to design for manufacturing or DFM checks
• Film creation
• Mapping of copper paths
• V-scoring
• Testing, and all of the phases between and after

Not surprisingly, any firm that offers same-day turnarounds for turnkey PCB assembly seems like an impossible thing, but at Advanced Circuits, we offer just that, and more.

No Outsourcing with Advanced Circuits: We Proudly Produce & Stand Behind Our Work

It is a frustrating truth that most manufacturers face the risk of outsourcing on almost anything they use or buy. Outsourcing is no longer limited to customer service and other phone service options alone, and if it is turnkey PCB assembly that is in question, the risks of trouble increase with outsourcing. From errors or flaws in the design process, to manufacturing glitches that result in wasted money and time, it is unwise to look to brokered or outsourced solutions for a turnkey PCB assembly process.

Working with Advanced Circuits means buyers get the kinds of hands-on results that are so important and desirable. With us, all circuit board designs pass through a series of rigorous examinations long before production begins. We are not a broker but are instead a reliable one-stop solution; making everything in-house, eliminating production problems and supplying turnkey PCB assembly and results required for success.

In this post, we define some of the basic elements involved in the printed circuit board assembly process.  For a detailed list of PCB assembly requirements, frequently asked questions, and a helpful Assembly Checklist, please visit our Printed Circuit Board Assembly services page.

Solder Paste – Solder paste is a combination of flux, a chemical created to assist in the bonding and melting of the metal, and small fragments of metal (solder) in order to apply the electronic components to the printed circuit board. The paste is placed on the board in specific places along the board in exact amounts with the use of a Solder Stencil and a paste application machine, automatically. When an automatic machine is not available to you, it must be executed manually and with the utmost precision.

Pick and Place Machine – This machine is essential in an automated printed circuit board assembly process.  The machine is programmed to automatically coordinate with complete accuracy the places to precisely mount each electronic component to be soldered to the printed circuit board. These machines are exact and quick. Human pick and place has a much higher potential for errors in addition to being a much slower, more tedious process.

Infrared Reflow – After the precise bonding element (solder paste) is applied to the PCB, the board will be directed to the reflow oven to join the electronic components to the board by melting the solder paste. This “oven” is comprised of many heaters whose main function is to heat the board to a precise temperature and control the level of cooldown as the solder hardens. This process is crucial to the creation of properly functioning electronics. The printed circuit board will run through a series of testing to ensure no issues or short-circuiting nor misalignments have occurred.

Thru-hole PCB Assembly – A method of soldering electronic components in place by hand using drilled holes in the printed circuit board and connecting pads.  This technique creates a stronger physical bond of the component to the printed circuit board but is much more time consuming and the cost of the printed circuit board can increase due to the higher volume of drilled holes.
