Product Overview

Our Single-sided OSP PCB is manufactured using high-quality base materials and advanced Organic Solderability Preservative (OSP) surface treatment technology. The OSP coating forms a protective organic layer on the copper surface, preventing oxidation while maintaining excellent solderability.

As an environmentally friendly and economical surface finish, Single-sided OSP PCBs are widely used in consumer electronics, LED lighting, household appliances, industrial control systems, and various electronic products requiring reliable assembly performance and cost-effective manufacturing.
