When designing a printed circuit board for devices such as fitness trackers and hearing aids, reliability is going to be at the top of your list of requirements. Flex PCBs are the go-to options for these types of applications because they’re rugged and reliable,...
For her MIT master’s thesis in engineering, Michelle Rybak investigated signal loss over frequency of six different PCB laminates, with special attention to distinguishing the resistive loss by the copper from the loss caused by dielectric absorption. er research...
Mythbusting the Semi-Additive Process Prudent PCB designers used to have good reasons for avoiding trace widths and spaces smaller than 3 mils beyond very short spans. But the 3 mil limitation is now becoming a thing of the past, thanks to the use of semi-additive...
Since the turn of the 21st century, there has been intensive research toward the development of embedded optical channels for transporting high-speed digital signals within printed circuit boards. I suspect that an alternative to copper traces might be commercially...
