Separability requires that a connector has the capacity to be mated and unmated multiple times without any unacceptable effect on...

Recall the functional definition of a connector from Chapter I/1.1 Connector Function. A connector is an electromechanical system which provides...

The classic noble metal contact finish system is gold over nickel as discussed in Chapter II/2.1.2 Contact Finish Degradation Mechanisms....

Tin and silver are the two most common used non-noble finishes. Tin finishes are used in a wide range of...

Selection of an appropriate finish system for a given connector application requires consideration of a number of connector and application...

Connector contact lubricants are used to provide two different performance benefits; reduction in friction and corrosion protection. Reducing friction will...

Silver surfaces react with sulfur and chlorine. Silver sulfide films, tarnish, are readily displaced on connector mating, but have been...

As noted previously, nickel surfaces always consist of a self limiting and very thin layer of nickel oxide, 0.01 µm...
