三叉金片 Gold Contact Series
Model:三叉金片
Three-prong gold contact stamping manufactured with tight plating quality controls, guaranteeing a clean surface free of white streaks, discoloration, haze, burn marks, and contamination. Batch-level color uniformity is enforced to eliminate visible differences within the same reel or production lot. Commonly used in multi-point connector contacts, precision switching components, and electronic modules requiring reliable low-resistance gold-to-gold mating surfaces.
Key Features
- Three-prong stamped gold contact with tightly controlled electroplating quality
- Surface free from white streaks, reddening, blackening, haze, and burn marks
- Intra-batch color consistency enforced — no color difference within same production reel
- 90° bend plier test confirms zero plating peeling across all three prongs
- Precision three-prong geometry provides redundant contact points for improved reliability
Key Specifications
- Service type: connector terminal electroplating / selective plating
- Connector family: Custom connector or industrial hardware
- Plating focus: gold, nickel, tin, or selective plating stack per customer drawing and RFQ requirements
- Quality focus: appearance, adhesion, bending performance, contact zone consistency, and batch color control where applicable

Frequently Asked Questions
What is the reliability advantage of a three-prong contact over a single or two-prong design?
Three contact points provide redundancy — if one prong experiences contamination, wear, or slight misalignment, the remaining two maintain the electrical connection. This is particularly valuable in applications with repeated mating cycles, vibration, or environments where contact surface degradation is a concern.
How is color consistency controlled across a production batch?
Gold plating color is directly influenced by bath chemistry, temperature, and current density. CZT monitors these parameters continuously within each production run and performs visual comparison checks across the reel. Any color variation within a batch triggers process review and rejection of affected parts before shipment.
What base metal is used beneath the gold plating on these contacts?
The base metal is typically a copper alloy — commonly brass or phosphor bronze — selected for its spring properties and electrical conductivity. A nickel underplate is generally applied before gold to act as a diffusion barrier, preventing copper migration into the gold layer which would degrade solderability and contact resistance over time.
