We use boots / shunts er wutt ever you call them to protect solderable component surfaces from wave soldering. Not sure how it would work in your case try: * Kinnarney Rubber 450 Main St. P.O.Box 37 Mantua, N.J. 08051 609-468-1320 fax 7438 http://ww

| | | | We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design)

Hello there We assemble Add-On cards for the Personal computers. Naturally all of them have gold plated edges to be connected into the pc. My question is : What is the best way to isolate these edges while soldering in the wave solder M/C. Hany

Hany: I have never understood why the add-on boards in PCs have gold plating on their connectors. In the military and in avionics, they require gold on connectors to protect from wear and corrosion. But PCs ave very different. PCs: * Are obsolet

There are several ways to do this, if you are doing large volumes the best way is to use Titanium Finger Masks. You can have them custum made or if you are lucky one of the standard sizes will fit. They slide over the fingers to protect them through

500 insertions � 50 m gold => 300 insertions � 30 m gold => 50 to 75 insertions � 20 m gold => 10 insertions. " Dave stated that the 'm' referred to micro-inches. I could probably insert this board 1000's of times without a problem. Am I missing so

If the gold fingers are pad types which plug into expansion slot connectors, I have used a titanium guard attached to the wave conveyor over the solder pot, which allows the PCB to connect to the fingers but masks the solder from the gold pads along

Annular rings are too big, it is acceptable to have shorts on the common conductors. I would be willing to say the "other" supplier may have modified the artwork as well. Good fluxing, preheat and proper immersion depth are key to eliminating short

Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connector
