That is correct, you make sure you have done proper grounding

for YOU prior to dealing with the card. Usually after one scrub,

that was it. It was always new cards that needed that touch or

very old ones that has been setting in a machine in a grubby

environment. Obviously if you have to do it so much that you

rub the contacts down, there is something wrong elsewhere.

I got the impression that the OP was "streaming" the thought. I suspect it meant that before working on computer internals, pay attention to operator grounding. My experience was that older edge connectors were subject to oxidation. Removing the device and rubbing the edge pins with a "genuine" rubber erase, which contains an abrasive (compare with the eraser that removes polymer lead marks), would scrub off the oxidation. Problem is that used aggressively it tended to wear right through the electrical coating on the pins.
