I have a problem with measling on our PCB's. We saw it on our FR4 PCB's at final assembly yesterday. Is this a defect from the board vendor or something we did in our assembly process when building the PCA's (thru hole). Could the wave solder mach

| Dave, | How thick are your PCBs? Do you have adequate topside preheat or are the bottom preheaters turned up to ensure proper filleting on the top side? | Rob Rob, The average PCB is .062". There is no topside preheaters on our machine

We are investigating alternatives to HASL finishes for more dense PWBs. OSP is not a good choice because of low solid flux and possibly long shelf life. Immersion gold is expensive and so far has been more difficult to wave solder. Has anyone had

Can anyone tell me if there is a reference for smt component height specs on the bottom side of a board, which will also go through wave soldering. A current design I am reviewing has tant caps(7343) and a crystal on the back side. Should I only be

Hello John, Just a thought, try contacting your equipment manufacturer. They usually see a bit of everything when it comes to applications. Maybe they can recommend a solution. Sometimes this involves purchasing something, but at least you can ta
