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

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

I assume the connector is like one used in PC104 that allows mating of boards together by inserting the pins extending from the connector on one board into the female portion of the connector on a second board. Who ever accepted this job is dopey.

We have a new custumer that needs thier thru-hole/smt boards conformally coated. We currently do not have a selective spraycoating system adn this low volume of these board do notwarrant a 100k machine. We are spending way to much time masking and un

We use a locally made fixture that uses tooling pins and a mating block to place the connector onto/into. We then use a toggle clamp to push the connector onto the board. We had to make no adjustments to stencil for our application. Russ

Hi Everyone, Could someone please tell me - What happens if a N-type connector having chromate coating over silver plating is hand soldering to a PCB. Does the Chromate coating form a compound with silver, Or does it come off while cleaning excess

We're unaware of any such reaction. The RoHS Directive bans the use of six hazardous materials. The materials are four metals: lead, cadmium, hexavalent chromium, and mercury; and two brominated flame retardants: polybrominated biphenyls (PBB) and p

Hello SMTNet, We had received boards from our CM, some came with a Tin plated finish on the SMT hermaphroditic edge connector, while others came with Gold plated on the same connector. Tyco supplies both version and they apparently mixed up parts.
