military connector


Six Basic Connector Test Procedures

1.       Physical test
Size, material, high temperature resistance, SMT test, constant temperature and humidity, thermal shock and wire

2.       Chemical test
Finishing, dipping tin, salt-spray

3.       Electric performance test
Connection point, dielectric strength, contact resistance, insulation resistance

4.       Mechanical test
Torque force, insertion and extraction force, swing, evenness, abrupt pull test, retention

5.       RoHS
RoHS-XRF test

6.       High frequency NA/TDR
Impedance, voltage standing wave ratio, return loss, insert loss, capacity.

Above tests is only for industrial electronic connectors; for military or aerospace connectors, some will be plated with nickel or cadmium just as D38999 connectors to apply into harsh environment.
