Do you have a solderable surface (walls)? It looks like most walls have a silver arc at the top but some do not (especially the last link) which I interpret that it has been plated (in most cases). Is it possible that the component does not have suff

We are experiencing a few issues every now and then with acceptable reflow results? We have changed solder paste, thus reflow profile types and even reflow ovens but we still seem to get some not so good reflow on certain pcbs. We can even take PCBs

Hi guys, Problem: Mid chip solder balling. Component affected: 0603 caps only Defect is PCB specific (Meaning only one PCB is affected as the aperture is standard for that component). As a containment I'll give a home plate design for the compo

We are having an issue with the solder bars hanging the solder feeder dripping down the back side of the pot, and leaking in to the area where the terminal block for the elements on the pot are. We have tried aluminum tape to close off the gap betwee
