It’s tempting to think that because they so closely resemble the generations that came before, today’s circuit boards are not all that different from what they once were.

However, from the materials available to heat resistance, from transfer rates to size, circuit boards have evolved a great deal over time. They also continue to change as our demands do. Not sure what that change might look like as we move forward? Let’s take a few minutes to explore some of the most important current and emerging trends in circuit board design.

Medical Devices

One of the most notable trends today is the spike in demand for medical devices. These run the gamut from hospital and medical clinic equipment like ventilators to devices used by EMTs and paramedics and those designed for consumer use. Circuit board design for medical devices must meet stringent requirements in terms of safety, reliability, heat resistance, and more.

Wearable Devices

From medical devices to fitness trackers, there’s a massive shift toward wearable devices. These must contend with a broad range of stressors that other devices do not face, although mobile devices, such as smartphones, come close in some cases. These factors range from dramatically decreased footprints to how to safely discharge heat and even water resistance in some cases.

Embedded Antennas

Today’s low-profile electronics demand something more than massive mast antennas, and designers have offered up embedded antennas right in the circuit board. Of course, this requires some advanced materials and unique design considerations to ensure full functionality. They play a role in Wi-Fi enabled devices, IoT devices, and much more.

Lead-Free Designs

Another important trend is the shift away from lead-containing laminates. Lead has played a role in circuit board design for decades, but it appears to be slowly falling by the wayside. Why, though? It’s largely to do with the higher heat levels that some of today’s devices must contend with, which would reduce lead to a toxic puddle at the bottom of the device. New lead-free laminate materials are being introduced to cope with those high heat levels and maintain their structural integrity at all times (not to mention eliminating those toxic fumes).

High-Power Boards

Just as circuit board designs must contend with higher heat levels than ever before, they are also being designed for higher and higher power levels (which also affects heat, of course). Most of these boards are above 48 volts, and they can be found in a wide range of applications. Many of them harness solar power, while others are intended for use within electric vehicles. IoT devices, battery-powered devices, and those with additional components – all of these are high-power applications.

The Growing Role of IoT Devices

As touched on above, IoT devices are having a profound impact on circuit board design. One interesting trend here is that the PCB industry is expanding. In the past, it was largely focused on consumer electronics. Today, that is still the case, but there is a growing focus on serving industrial needs because this is where the vast majority of IoT devices can be found. While Alexa, Siri, Ring doorbells and the like are all being integrated into homes, the real demand is within the manufacturing and industrial sector where entire production lines are now integrating internet connectivity and being networked together.

Not only does this mean that there is an increasing demand for circuit board design and manufacturing, but that PCB designers face some unique challenges. One of those is the change in what “protection” and “security” mean. Previously, it was really all about protecting the circuit board against environmental changes. Today, though, it is becoming more about prevention against tampering.

Flex and Rigid Flex

Previously, both flex and rigid-flex boards were relatively rare in the PCB world. Today, that’s increasingly not the case. That’s due to a couple of the trends that we have already discussed. One of those is the rise of medical devices – ideally suited for flexible circuit boards. However, flex boards are also well-suited for consumer electronics, for use in a range of different sensors connected to IoT devices, and even medical implants.

On the other hand, rigid-flex boards combine the benefits of both flexible circuit board design and rigid boards. The result is a board that “plays well with others,” which makes these well-suited for use as sub-boards and for creating additional layers.

Waste Control

Waste is a growing problem. This is particularly true of e-waste. Finding ways to deal with the growing mountain of disposed-of electronics is a challenge, but one option is to use biodegradable circuit boards. Biodegradable PCBs offer some light at the end of the tunnel and a way to start greening up the industry. While workable circuit board designs using biodegradable materials are still some way off, they are coming. It will require the design of new substrates, as well as a shift away from chemical-based etching processes in many cases.

Printed Circuit Board Design Is Never One Size Fits All /blog/printed-circuit-board-design-is-never-one-size-fits-all/ Mon, 16 Dec 2019 22:52:48 +0000 https://dev.4pcb.com/blog/?p=2069 Continue reading ]]> PCBs or printed circuit boards have been in use for a long time and they are in demand across a diversity of industries, especially electronics of all kinds. Though many consumers assume that circuit board design is a uniform matter without a lot of changes or innovations, those in any part of the industry know that there is always room to improve, streamline and redesign according to need. Unfortunately, the costs associated with circuit board design can be a bit prohibitive to some, and so they do not try to make their own modifications or changes, settling for something ill-fitting or less than desired.

After all, prototyping means designing something new, having the unit made, addressing flaws or design issues, and only then sending it into production. There is always the risk that a design flaw might be overlooked, and working with subcontractors can actually increase such concerns. All of these factors are why so many people will avoid the entire process and stick with a less than desirable solution. Settling for a stock or standardized design, however, is not a forward-thinking approach.

The good news is that there is no such thing as one size fits all circuit board design. Advanced Circuits, a top industry manufacturer, offers an array of resources capable of empowering firms with even limited budgets to upgrade, customize and enjoy flexibility. Of course, it helps to have a bit more clarity on just what is available generally before delving into the options in custom printed circuit board design.

The General Options in PCB Design

A simple or basic list of the options for PCB design include:

  • Single Layer
  • Double Layer
  • Multi-Layer
  • Rigid
  • Flexible
  • Flex-Rigid
  • High-frequency
  • Aluminum-Backed
  • Full Spec
  • LDI
  • Oversized
  • Heavy copper
  • and more

Clearly, this means an array of production capabilities has to exist and come in at the right price and quality points to meet such a diversity of potential needs or designs. Advanced Circuits can supply almost any type of production capability and facilitate premium circuit board design that goes along with it.

Optimal Circuit Board Design from Advanced Circuits

In addition to there being such a diversity of PCB types, there will be many design needs. For example, printed circuit board design may involve only a single layer, or it might be two-sided, but the complexity of modern electronics may necessitate up to 28 layers incorporated into a design, and each layer will require synchronous interaction. This means there is always room for error in circuit board design, and the option for multiple sets of eyes and various levels of expertise may prove remarkably beneficial and cost effective.

Because of that, Advanced Circuits has created a system of tools, resources and services that are all meant to facilitate optimal circuit board design. The resources and services include:

  • Expert advice – In addition to classic customer support, our team includes access to CAM engineers 24-hours each day. Customers are able to phone in design and engineering questions and have them answered by a professional engineer.
  • Expert Reviews – CAM engineers also conduct a thorough review of each design as it is about to enter into the production process. This is a final check and guarantees that there are no issues that might lead to a negative outcome.
  • Full and free design support – In addition to expert engineers, Advanced Circuits offers industry best software meant to enable superior design. PCB Layout Software – PCB Artist features a library of more than 500k tools and components that can be built into designs of up to 28 layers. It can control auto router functions, multi-page schematics, and more. It is offered in an unrestricted format, meaning it comes at no cost but allows top-of-the-line design options.

After that, clients are able to use the FreeDFM program, which requires an export to Gerber file format and upload to the Advanced Circuits website. Once that fast and easy process has been completed, the client can enjoy a full evaluation of the PCB design. A report is emailed to the provided contact and it explains which flaws were discovered, remedied and what were targeted as potential showstoppers, but left in place.

As any professional knows, PCB design is the key factor in the whole process. A single error makes a prototype a failure or an entire batch of PCBs useless. It could lead to enormous wastes of time and resources. Yet, the entirety of the process does not begin and end with design. There are other factors that impact whether or not printed circuit board design is as successful or effective as it could be.

A lot of it has to do with the approach the producer takes to the process. Advanced Circuits ensures that its clients experience a process that empowers their success, from the design phase to assembly. This means that we:

  • Keep it in house – Our enormous production facilities are Advanced Circuits’ way of proving commitment to the entire process. We are able to work with design files and a team of engineers that ensure files are complete and appropriate to the client’s goals. However, we also handle fabrication and assembly on the premises, too. While so many modern manufacturers are “no touch,” we are most distinctly hands-on and manage every aspect of a project.
  • Comprehensive website – The ease with which clients can get the tools needed and then use them effectively is only one part of our service. We also provide instant quotes, unique client pages where previous orders and simple reorders are possible, stencils, file uploading, order tracking, and “through software” orders. Design something using the free PCB Artist software, and order it once it has cleared the CAM or free evaluation services. This also gives clients a discount on any standard spec orders.
  • Tooling fees – Many manufacturers impose a tooling fee on standard spec orders, but clients can count on a fee-free process with Advanced Circuits. Even if a custom spec orders is re-ordered, the tooling fees are cancelled out.
  • No minimum orders – Budgets are protected by Advanced Circuits’ no minimum order requirements, and whether it is a single board with a single day of turnaround time or a huge order, the quantity is in the hands of the clients.

Advanced Circuits Removes the Challenges in the PCB Production Process

The PCB design and production process is full of potential challenges and issues. Advanced Circuits clients receive their specific designs without breaking the budget, slowing production times or wasting resources. Whether clients need one PCB, small batches or larger orders, Advanced Circuits can produce quality printed circuit boards to client requirements.
