Hello Russ, I'm not quite sure I understand your question. Are you saying that you must hand solder these connectors because the gold plating doesn't allow other though hole processing methods to wet the solder the length of the pin in the PTH? Reg

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t

Hello Dave, As related to connector mating interface, fretting corrosion is the oxidation of the contact points, causing high resistance across the interface. Fretting corrosion is caused my micromotions in the interface exposing the metalized conta

Jim, you are right in this. these connectors have long pins 1/2" or so that protrude through the board and are used for mating into a female connector on some other assembly. due to both length and "no solder allowed in contact area" criterias thes
