AI Overview
Organic Solderability Preservative (OSP) on PTFE (Teflon) PCBs provides a cost-effective, lead-free, and highly coplanar surface for high-frequency applications, ensuring excellent solderability by protecting copper from oxidation. It is ideal for flat surfaces but unsuitable for long-term storage or multiple soldering cycles, generally requiring assembly shortly after fabrication.

What is the difference between OSP and ENIG finish?
Surface Flatness
Both OSP and ENIG offer flat surfaces, making them suitable for fine-pitch SMT components. ENIG, however, provides a more consistent finish with thickness control within 0.05-0.1 micrometers for the gold layer, ensuring precision for high-density designs.Sep 24, 2025
