I discovered that we have some gold plated (30 mico in.) through hole connectors which were Paste In Hole soldered (60 sec at reflow) on a HASL PCB. Do we have an embrittlement reliability issue? The calculated volume % of gold in the joints is about

Wayne, Earl, I wish there was some way we could toss our wave solder machine forever! Unfortunately, we haven't found a way yet to do paste-in-hole reflow for large numbers of thru-hole axial and radial components, which we insert on Universal machi

Hi, in my experience, the humidity is trapped in the solder paste. Otherwise you can also try to : adjust preheat profile, and /or increase paste viscosity, and /or increase paste metal content (they are the most common causes).
