铜带镀金 Copper with Series
Model:铜带镀金
Gold-plated copper strip designed for high-reliability electrical contact applications, manufactured to strict surface quality standards that permit only minor single-side scratches while prohibiting visible defects within any 1-meter span. The substrate must be free of creases, copper marks, and surface unevenness to ensure consistent plating adhesion. Commonly used in precision connector terminals, lead frames, and high-frequency signal transmission components.
Key Features
- Gold-plated copper strip with zero visible surface scratches within 1 meter
- Single-side minor scratches acceptable; both-side scratches inspected to stricter standard
- Surface free from creases, Cu marks, yellow spots, haze, and water stains
- Continuous slight texture permitted; no unevenness or incomplete degreasing allowed
- Manufactured for high-reliability electrical contact applications requiring consistent plating quality
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 surface defects are acceptable on the gold-plated copper strip?
Single-side minor scratches are permitted. For both-side scratches, only the minor side is evaluated. No visible scratches are allowed within a 1-meter inspection distance. Continuous slight texture is acceptable, but creases, Cu marks, yellow spots, haze, white spots, water stains, and incomplete degreasing are all rejected.
What gold plating thickness is available for this copper strip?
Plating thickness is specified per customer drawing or purchase order. CZT can accommodate selective gold plating on contact zones to optimize cost while maintaining full performance on critical surfaces. Contact our engineering team with your specific thickness and hardness requirements.
Is this strip compatible with high-speed stamping and forming operations?
Yes. The copper base material and plating adhesion are qualified for progressive-die stamping. Surface quality standards ensure the strip feeds consistently without tool contamination or contact degradation during high-volume terminal production.
