PCB Surface Finishes We Support
The right surface finish protects exposed copper and supports reliable soldering and electrical contact. Compare the options based on your component pitch, assembly process, storage requirements and budget.
HASL Surface Finish
Choose HASL for conventional PCB designs where cost and solderability matter more than a perfectly flat pad surface.
- Cost-effective PCB finish
- Good solderability
- Suitable for standard component pitches
Lead-Free HASL Surface Finish
Use lead-free HASL for general PCB assembly when your project requires lead-free materials and conventional component pitches.
- Lead-free solder coating
- Good solderability
- Economical for standard PCB assembly
ENIG Surface Finish
Choose ENIG for fine-pitch SMT, BGA and QFN components that require flat soldering pads and good oxidation resistance.
- Excellent surface flatness
- Suitable for BGA and QFN assembly
- Good solderability and storage performance
Immersion Silver Surface Finish
Choose immersion silver for fine-pitch and applicable RF PCB applications that require a flat, solderable copper surface.
- Flat soldering surface
- Suitable for fine-pitch assembly
- Controlled storage and handling
Immersion Tin Surface Finish
Use immersion tin when your design requires flat soldering pads or compatible press-fit connections.
- Excellent pad flatness
- Fine-pitch assembly support
- Suitable for press-fit applications
OSP Surface Finish
Choose OSP for cost-sensitive SMT production when storage conditions and assembly timing can be controlled.
- Flat copper pad surface
