Frequently Asked Questions
What is the advantage of hard gold plating over standard gold flash?
Hard gold (typically gold-cobalt or gold-nickel alloy) offers significantly higher wear resistance than soft or flash gold. It maintains stable contact resistance over thousands of mating cycles, making it the preferred choice for edge card connectors, test sockets, and high-reliability interconnects in demanding environments.
How does CZT inspect for plating defects on Model A connectors?
Each batch undergoes visual inspection for surface anomalies including yellow spots, black spots, white spots, water stains, incomplete degreasing, and plating skip. Mechanical bonding strength is validated by bending with needle-nose pliers — any plating that peels is rejected. No scratches or abrasion marks are accepted.
What plating thickness options are available for the Hard Gold Series?
CZT can accommodate various gold thickness specifications depending on application requirements. Contact the technical team with your mating cycle count, operating environment, and contact resistance targets to determine the appropriate gold thickness — typically ranging from 0.1 µm flash to 1.27 µm or more for high-wear applications.
