Hello Russ, I'm not quite sure I understand your question. Are you saying that you must hand solder these connectors because the gold plating doesn't allow other though hole processing methods to wet the solder the length of the pin in the PTH? Reg

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t

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

Hello Dave, As related to connector mating interface, fretting corrosion is the oxidation of the contact points, causing high resistance across the interface. Fretting corrosion is caused my micromotions in the interface exposing the metalized conta

Back in the 50's, 60's and 70's gold plated boards were all the rage for high reliability. test equipment, milspec etc. Nowadays only edge connectors are gold plated. Immersion plated gold is also used but it doesn't last the distance like gold plate

Assuming you are talking about solderable surfaces: People specify various materials to protect the solderability of the pads on the board. Gold, actually, Electroless Nickel - Immersion Gold [ENIG], is popular. * Board fabricators like it because

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)

We are having solder fillet finish issue. The solder looks like rough solder on the connector leads .The plating of the leads is Nickel (99.9% purity) and the PCB plating is imersion gold. I have tried fine tuning my reflow profiles an have used N2 i

Questions are: * What is the current plating on the connector that is over the "plating of the leads is Nickel (99.9% purity)"? * What are the temperatures and durations at those temperatures that you read on these connector leads? * What solder allo
