Plating Adhesion

Composite connectors (Class J and M) provide the benefit of a lightweight construction with limited drawbacks. To verify the connector plating in high temperature operation conditions, the plating adhesion test is performed.

For this test, the connector under evaluation is immersed in oil at its operational temperature.  It is then quickly cooled to room temperature by immersion in a solvent or ice water. The connectors are then removed and visually examined for any separation or loosening of the plating.
