30 µinch Gold Mating Finish — Cycle Life and Corrosion Margin
In a production harness that mates and unmated 50 times over the product life, this plating grade keeps the contact interface stable without tin-whisker or fretting concerns. The solder tails carry a tin-lead finish (100 µinch), which wets well during wave solder and gives a reliable fillet on the PCB pad.
