Don't have the figures to hand but having checked it out a while ago we have moved from the gold/yellow zinc passivation on steel parts to the silver/clear finish: UK spec: BRIGHT ZINC PLATE TO BS 1706 Fe/Zn 8 c 1A US spec: BRIGHT ZINC, ASTM B633, TYPE III, Fe/Zn 8 This has a much lower resistance. We found the "gold" unacceptable for emc considerations. Chris James Engineering Services Manager Dolby Labs Inc.

I have searched through the RCIC "Recent Threads" and could not find a related subject. Can anyone steer me to that thread? (something about "yellow ____"?)
