I had the opportunity to spend time with a demo and one on one with the inventor of the Ersa scope inhouse a few months ago. I see the scope complimenting X-ray inspection but not as a substitue. It allows you to view attributes of a solder joint t

I agree with Dave that passte volume is the most preferable criteria. However, you need to determine what you will accept and what your process is capable of. You need to define the process parameters, put procedures in place to control them, reduc

Hi Wolfgang, Thanks for the response. We had a similar situation to yours with some white tin samples that sat around for about eight months. Samples soldered right after they arrived soldered better than the ones we soldered eight months down the

I have tried the water soluble flux and the aqueous cleaners but I got the same results you did; horrible corrosion and a white flaky mess. I know exactly what you're talking about. We do a lot of hand soldering around here, and the magical solutio

Greg, The best advice that I can give you is a PBGA will respond just like any other surface mount package. There may be a 5 degree delta between a PBGA 356 and a QFP208 but the two respond very similarly in the convection reflow environment. CBGAs

When doing PIH processes, it is critical that you control the solder VOLUME, not the height. You must define the process, monitor it and control chart it to keep the paste volume consistent. You have do some careful engineering to determine how muc

I am not sure if I have seen an article comparing solder joint strength Vs pressfit although I am sure this has been researched by literally hundreds of companies before they felt comfortable going to pressfit. I know one of the issues with solder is

Should I manufacture my own boards or outsource them? Any opinions are welcome. I own a company and sell electronic products. Some products we sell have specific ad-on circuit boards which I have designed and had manufactured just for my company. The
