This month, I’m going to cut through some of the more heavy-going tech-speak, taking a few of my customers’ more frequently asked questions about resins to try to help you refine your selection process. There’s a lot of ground to cover, but for the purposes of this column, let’s concentrate on the PCB’s operating environment, caring for the components that are to be encapsulated, and the special needs of applications like LED lighting and RF systems.
Many years ago, I was given the opportunity to switch my career path from senior circuit board designer to CAD systems administrator. I wasn’t certain that I wanted to give up the comfort of being a designer; after all, I had been one for a long time. But I knew that this transition would help my overall knowledge base of everything CAD-related, as well as better position me in my quest for a management position. So, I pulled the trigger and accepted the new job even though the idea of stepping into the great unknown like that was very intimidating.
In an ideal world, the entire signal waveform would uniformly decrease in amplitude, over distance, and the rise time would remain constant. This reduction in amplitude could easily be compensated for by applying gain (cranking up the...

The primary issue is generating optimal FPGA pin assignments that do not add vias and signal layers to a PCB stackup or increase the time required to integrate the FPGA with the PCB. Engineers generally do not consider FPGA pin...
