Via in pad is a designer's dream and an assembler's nightmare. Search the fine SMTnet Archives for previous discussions to get started. VIP, via-in-pad, or whatever tend to promote voiding within the via and certainly partially starved solder conne

Hi Carlton, I'm sure you are a good person who wishes to explore something new, each time. Your attitude is absolutely human, but is not always appreciated by the professional world. I read your resume and would like to advise the following: 1. Since

Is the wheel that drives the belt in alignment? I assume all the bearings are turning. We've had bearings in the past be on the edge of seizing in our end pulley's. Tightening too much could cause it to turn harder, causing the belt to jump off. Coul

I have not been able to find a standard which governs component lead sweep. We use an internal standard of 4 mils here at Sanders, and your 6 mil sweep would definitely be unacceptable. I believe the reason there is no standard governing sweep is b
