10-layer, three-stage OSP (Optical Sealant Propagation) green solder mask board, featuring a combination of laser-drilled vias and mechanically drilled through-holes, with strict control over drill residue removal and OSP uniformity. Mechanically drilled through-hole burrs are ≤8μm, and overlapping areas with blind vias undergo two rounds of adhesive removal. UV strengthening is applied after green solder mask development to enhance surface hardness. Micro-etching of the copper surface before OSP film application achieves a uniform pink appearance, with a film thickness of 0.25-0.4μm. Four simulated reflow soldering cycles are performed, with a wetting angle ≤25° and no film cracking. Ion contamination testing is conducted on each batch.
