Hello, Welcome to the Altium Learning Hub

In this episode, we will continue with the topic of Design WITH Manufacturing, and joining us is Mike Vinson, the Chief Operating Officer at Averatek. Mike will help us understand Averatek’s advanced PCB manufacturing processes, including the technology and chemistry behind A-SAP and 3D printing.

When we talk about copper roughness, we always bring it up as if it were a universally bad thing. The fact is, some circuits will always function just fine even if the copper is rough. As long as your traces are fabricated to spec in every other area, the roughness of the traces might not matter as long as your operating frequency or bandwidth are low enough. Just what constitutes “low enough” and when is the effect of roughness so small that we...

Anytime a company wants to develop at the leading edge of technology, it requires a ton of development from the ground up. In the realm of quantum computing, this is still true; companies that want to operate in this area of technology have to build just about everything from scratch. But today, the industry has taken an important step towards accelerating development of quantum devices. On 28 March 2022, Dutch company QuantWare announced...

The major trend in the electronics industry is miniaturization, where more features and more complexity are packed into a smaller footprint and less board space. High density interconnect (HDI) PCB design is the manifestation of miniaturization at the circuit board level, where smaller components and higher density force changes in design practices and manufacturing processes. HDI PCBs are heavily rules-driven, with most of the rules involved...

The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen in TDR measurements. As we design any printed circuit board and develop circuits that operate at higher frequencies, it may be tempting to opt for the...

Of all the noise and operational challenges designers face in their PCBs, there is one overarching problem that is arguably most popular: electronic noise. Any noise you pinpoint in your system could have one or many possible causes and solutions. It could originate as an SI/PI problem, it could possibly arise from some external source, or it could be good old-fashioned crosstalk! Whenever some noise is measured on signals and it presents some...

Any time you design a PCB and want to turn it into a real product, you will have to make sure the design obeys the constraints within the standard PCB manufacturing process. This imposes multiple rules on any design, and ECAD software will enforce design rules as you create the board to ensure you obey these important constraints. The ever-increasing complexity of boards has made it nearly impossible to carry out the design rule verification...
