Surface Finishing
Surface finishes selected for solderability, flatness and shelf life.
Surface Finishing with ShinePCB
The surface finish protects copper and prepares pads for assembly. Options such as ENIG, HASL and OSP are matched to your assembly process and application and confirmed in the quotation.
- Assembly process and component types
- Flatness needs
- Shelf life and storage
- Selective finish requirements

Surface Finishing FAQs
Which finish should I choose?
It depends on components, assembly and application. Engineering can advise.
Can one board use two finishes?
Selective finishes are reviewed per design.
