Designers, I need a little help on determining basic reliability/quality/corrosion/# of reliable insertions issues between Pin/Socket connectors and Gold Contact Fingers/Edge Conn. Naturally the gold fingers will be far less expensive, but are finger that far inferior to pin & socket for reliably connecting power to a system. This case the question is related to the actual power supply connection from power supply to backplane, either fingers going into press fit edge connectors, pin & socket mating connectors or forget going directly to the backplane and go cable. Is there any place for real data for corrosion/ reliability numbers. thanks Robert M.
