Gold contact surfaces are often used on circuit boards with membrane switches which are a technology of choice for industrial, commercial and consumer products. When PCBs will be repeatedly installed and removed, electroplated gold is used for edge-connector contacts or as they are more commonly known: Gold fingers. The plating thickness of a PCB gold finger is typically a mere 300 micro-inch. At this thickness the hard gold is expected to survive 1,000 cycles before wear through.

If layer to layer registration, tolerances for hole size, location, film expansion and registration have not been taken into account then manufacturing will experience high reject rates and increased costs.
