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

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

In the purest sense of ESD control, we would have to say yes, use ESD tape to cover the gold fingers. The gold fingers are connected directly to input/output controls for the card, and, as we all know, when handling boards, we're supposed to avoid c

Question: How many insertion/removal cycles can be expected of gold finger contacts? Problem: We manufacture a class 2 PCBA with gold finger contacts whose application will require repeated insertion and removal into card edge connectors (mother b

Talk about glam jobs � About once a month, we�d go over to the slaughter yard to get cows� teeth for Dr. Mueller. Then we�d fixture them on their side and run them in a machine that scrubbed them with a brush for weeks. The cool thing about cows te

I don�t have the answer for you but it would not be difficult to make a fixture to find out. Combine a counter, pneumatic cylinder, and a solenoid in such a way to do the job for you. Cylinder pushes the card into the connector, when contact is made
