Good afternoon all, I am looking for help from you folks to find a place that can do metalurgical analysis on components and contamination. We are an OEM and just recently received back from the customer several units that failed in the field after

Yea, I'm still here.....sigh. Got bridging problems. These assemblies are SMT topside, then go thru wave for thru-hole components on topside. These assemblies have many, many, many vias VERY close together. We have a problem with solder from the wa

Achieving high reliability and high efficiency in SMT process (Surface Mount Technology) assembly has always been the goal of electronics manufacturers expecting consistency. It depends on the optimization of every detail of the whole process. For SM
