| I have a board that has surface mount on both sides . On this board is a 22pin connector which is the only thru-hole part.This part is located on the component side. I would like to reflow this part. Can this be done? If so, how can this be done?

Recently, our solder dross reclaimer refused to take our used solder paste tubes. He said the small percent of paste remaining in the tube is now considered hazardous waste. I'm interested in advice on how others are disposing of this "hazardous wast

| | | One of the DFM suggestions I've seen is to remove the solder mask web, i.e. the mask between pads on 20-mil QFP devices. The rational is that if the mask is thicker than the pad the mask can prevent the stencil from making intimate contact wit

| We are using a mixed technology process with mostly through-hole parts plus some SMT IC's on the component side and some passive SMT parts on the solder side. We do not have a proper wave soldering machine for doing solder side SMT (double wave or

Does anyone out there have any experience with laser soldering? I have heard that there are special formulations of paste specific for YAG soldering of PCB's. I am having good luck with BGA, uBGA, and QFPs but I want to improve the process. Any su

Has anyone ever heard of testing solder paste quality by pasting a board and making a determination of the quality by measuring paste height and width after the board is pasted. Would you consider this a valid test for solder paste testing?
