PCB Surface Finish Selection: HASL, ENIG, OSP and Immersion Silver
Compare common PCB surface finishes by cost, solderability, shelf life and prototype suitability.
For overseas engineering teams, the fastest results come from complete data, direct communication and a factory that can combine PCB, SMT stencil, assembly and fixture support under one workflow.
Key Points
- Prepare Gerber, BOM, drawings and test requirements before quotation.
- Confirm material, tolerance, surface finish and delivery target early.
- Use factory engineering feedback to reduce rework and improve manufacturability.
Jingchengjie supports fast PCB prototype, SMT assembly, laser stencil and fixture manufacturing from Shenzhen.
