A medical-grade low-temperature OSP (Organic Solderability Preservative) coating is applied with a controlled thickness of 0.25–0.40μm. Micro-etching is maintained between 0.7–1.1μm, while copper surface water-break testing exceeds 35 seconds, ensuring optimal coating adhesion and uniformity. After five simulated reflow cycles, the wetting angle remains ≤20°, demonstrating excellent solderability.
The blue solder mask undergoes complete development verification and achieves a 5B adhesion rating through cross-hatch testing. Following post-curing at 150°C for 65 minutes, the PCB exhibits excellent insulation and environmental resistance.
