This 5G optical module features an 8-layer through-hole immersion gold plating with green solder mask, controlling glass cloth protrusion on the hole walls and preventing solder bridges from the green solder mask. Drilling employs a double-sided drilling process, ensuring no glass cloth protrusion on the hole walls, a roughness ≤10μm, and a backlight rating ≥9. The width of the green solder mask is ≥75μm, measured using 3D measurement after development, and then cured at 150℃ for 70min. Plasma cleaning is performed before immersion gold plating, resulting in a gold thickness of 0.05-0.10μm, no black pads in the nickel layer, and a salt spray test duration ≥96h. Ultrasonic scanning after thermal shock shows no delamination, and the copper elongation within the holes is ≥12%. Ion contamination is ≤0.3μg/cm², and each batch undergoes a 1000h CAF test for insulation resistance ≥10^9Ω. A dedicated 5G optical module QR code is laser-engraved on the board surface.
