All,
We are using a simple header connector (pin) and receptacle (socket) to make
a board to board interconnect.  The pins and socket are gold plated over 50
u-in Nickel, base material is phospor bronze.  We normally pre-tin the tails
for soldering to the PCB, and leave the interconnect areas gold.  Operator
mistakenly tinned both ends of the pi (using water sol flux and 63/37
alloy).  This would result in a solder coated pin inside the gold plated
receptacle.  I couldn't locate anything in IPC-610 about this condition.
Will it be acceptable?  Operating voltage @ 28VDC.  Avionics application.
TIA,
Kevin Glidden
