Automotive 6-layer through-hole immersion gold green solder mask, with strict control over interlayer misalignment and immersion gold layer stress. Interlayer misalignment ≤70μm, X-ray sampling inspection, warpage ≤0.5%. Drill burrs ≤10μm, hole wall roughness ≤20μm, backlight level ≥9. Plasma cleaning before immersion gold, gold thickness 0.05-0.10μm, nickel layer phosphorus content 8-11%, internal stress controlled at 80-120MPa. After green solder mask development, side etching ≤5μm, post-curing at 150℃×65min, insulation resistance ≥100MΩ. After thermal stress at 288℃×10s×3 times, through-hole copper elongation ≥12%, green solder mask blister-free. Ion contamination ≤0.6μg/cm², CAF testing for 500h per batch. Automotive-specific UL code engraved on board edges.
