At times the orange peel effect can be from excess flux improperly removed. Our company strictly provides the service of selctive conformal coating application. We quite often see this. Most times if the board is simply "water washed", or IPA washed,

Hi Everyone, Could someone please tell me - What happens if a N-type connector having chromate coating over silver plating is hand soldering to a PCB. Does the Chromate coating form a compound with silver, Or does it come off while cleaning excess

Via failure could be caused by cracks in the barrel, or thin plating, or fractures in the traces leading to the vias, . X-ray analysis could pick up a fractured trace and cross-sectioning of the vias could pick up the cracks and thin plating. Secon

We used an air knife using foam fluxer and no clean flux to remove excessive flux from the boards for a better look afterwards. A secondary effect might be that the flux is forced into the vias giving you better results on the top. If you feel a need

I've been in shops with a flux containment pan under the wave fluxer. While I'd rather see excess flux in a containment pan than on the floor, but I'd prefer to see flux applied precisely to eliminate the need for either using a containment pan or cl

Dave: Thanks for you Earl-Moonesqe explanations. To answer your 3 questions below: * If there�s no flux in the via, why does the sodder flow? I thought it was the flux that removed corrosion to increase wetting that allowed

What you can do is perforate the board holding rim by drilling holes of 0.6mm (similar to via's). This will reduce the mass and heatsinking capacity, allow excess flux drainage and facilitate convection heat contacting the board through the holes. Th

Recently I have been hearing and see this excess flux residue problem at several companies, US, Mexico, and Japan. It seems to have increased recently. In fact, it seems so common that it seems normal, but if everything is correct, a re-flow oven sho
