Forgive the non-SMT question. That's why I hate through hole boards. Has anyone ever used Bareco wax on pressfit connectors, and how do you produce a consistent process for its application? Any drawbacks? Background: We have found a design issue with

I had the same concern. The connector pins are gold also. I am waiting for a response from AMP to supply some of this wonder wax. I can inspect the HASL fabs for proper hole diameter, but I do not have a warm feeling I should be getting involved with

Hi I don't believe I have ever done this or seen it, yet maybe since there are some other lube processes. Ask the Amp Guy for any older App Notes. They used to have a lot. If I got this right you could put it on the board with an applicator that c

I'm working on a prototype board that requires a 600 pin BGA. This is a metal top BGA being placed on a 11" x 17" PCB about .62" thick. The part is 1.77" square with a 50 mil pitch and 30 mil bump diameter. The bumps are located on the perime

How many layers is the board.... Is the BGA ceramic or plastic? Dave Kennedy APE South apecorp.com
