Our Double-sided OSP PCB is manufactured using high-quality FR-4 materials and advanced Organic Solderability Preservative (OSP) surface finish technology. OSP coating provides excellent solderability while protecting the exposed copper surface from oxidation, making it an environmentally friendly and cost-effective surface treatment solution.
Double-sided OSP PCBs are widely used in consumer electronics, communication equipment, industrial control systems, automotive electronics, and various electronic products requiring reliable soldering performance and economical production costs.
Typical Double-sided PCB Structure:
Top Copper Layer
FR-4 Substrate
Bottom Copper Layer
OSP Surface Finish
The double-sided design allows components and routing on both sides of the PCB, providing higher circuit density and better space utilization.
✓ Excellent Solderability
OSP surface treatment ensures superior soldering performance and assembly reliability.
✓ Environmentally Friendly
Lead-free process compliant with RoHS environmental standards.
✓ Cost-Effective
Provides lower manufacturing costs compared to precious metal surface finishes.
✓ Flat Surface Finish
Offers excellent coplanarity for SMT assembly applications.
✓ Good Electrical Performance
Maintains stable electrical characteristics and signal transmission.
✓ Reliable Quality
Suitable for both prototype and mass production applications.
