两叉金片 Gold Contact Series
Model:两叉金片
Two-prong gold contact stamping with a high-quality electroplated finish, inspected to ensure no white streaks, reddening, blackening, haze, burn marks, or surface contamination. Color consistency is maintained within the same reel and across batches, with no variation in plating luster permitted. Designed for use in precision electrical connectors, relay contacts, and electronic assemblies where consistent contact resistance and surface quality are essential.
Key Features
- Two-prong stamped gold contact with electroplated finish meeting strict appearance criteria
- No white streaks, reddening, blackening, haze, burn marks, or contamination permitted
- Batch color consistency controlled — no color variation within same production reel
- 90° bend test with pliers confirms plating adhesion with no peeling or delamination
- Precision stamping geometry ensures consistent two-prong contact alignment
Key Specifications

Frequently Asked Questions
How is plating adhesion tested on the two-prong gold contact?
A gold strip sample is bent 90° using pliers and the bent area is inspected for peeling or delamination of the gold layer from the base metal. This mechanical stress test simulates the forces applied during connector assembly and confirms that the plating bond is sufficient to survive handling and installation.
What causes white streaks or reddening in gold-plated contacts, and how are they prevented?
White streaks typically indicate plating bath contamination or insufficient rinsing, while reddening suggests copper base metal exposure from thin or porous gold deposits. CZT controls bath chemistry, plating current density, and post-plate rinsing protocols, with 100% visual inspection to reject any parts showing these defects before shipment.
Can the two-prong contact geometry be customized for specific connector housings?
Yes. Stamping tooling can be modified to adjust prong spacing, width, thickness, and overall contact length to match specific housing cavities or PCB footprints. Custom designs are validated against the same appearance, color consistency, and bend adhesion standards applied to standard production parts.
