1.The copper surfaces are brown oxied.
2.the laser drill holes created with the method of Direct Laser Drill.
3.The conformal laser drill holes shapes are microsectioned and inspected with microscope (CY-930A).
4.The Brown oxide (0.35-0.45 mil thick) are removed from the copper surfaces.
5.The hydrocrabon residues on captures pads are removed by Plasma desmear.
6.The surfaces of captures pads are examined by LaserVia AOIM(MACHVSION).
7.Chemical desmear Alkaline permanganate cycle and panel plating are succeeded by Plasma Desmear.
8.The laser drill holes at sequential build-up are plated shut by copper plating like 4+N+4 or (ALIVH).
