Process overview
What this capability delivers
电镀服务覆盖各类精密零件。纯度等级公开:软金(III 型)≥99.9%、硬金(I 型)≥99.7%、硬金(II 型)≥99.0%。标准复合镀层为铜→镍→金,兼顾附着与表面稳定。选区(局部)电镀可精确定义镀区,保持功能特性并降低贵金属消耗。
Tolerance / technical data
Capability benchmarks with applicability
| Metric | Capability | Applicability |
|---|---|---|
| 软金纯度 | ≥ 99.9% | III 型 |
| 硬金纯度 | ≥ 99.7% / ≥ 99.0% | Type I / Type II |
Figures are capability benchmarks. Achievable tolerance depends on geometry, material and feature size — confirmed per drawing in DFM review.

FAQ
Frequently asked questions
提供哪些镀层体系?
封装与光学件用铜–镍–金体系,另有镀镍与选区镀金。镍层起扩散阻挡作用,金层提供可焊性与耐蚀性。
可以做选区电镀——只镀部分表面吗?
可以。选区电镀对非镀区做掩蔽,镀层厚度与覆盖范围按图纸定义。可参考可伐合金激光封装壳体选区镀金案例。
镀层厚度如何验证?
厚度由工艺控制并按询价时约定的检验方案验证——适用处用 XRF,破坏性检验用随炉试片。
