About Metallizing Half-Hole PCB
Metal half hole (groove) is a hole after the hole after the second drilling, shape process, and finally retain the metal hole (groove) half, simply said that the plate edge metallized hole cut half, the plate edge semi-metallic hole process is a very mature process.
How to control the product quality after forming the semi-metallic hole on the edge of the plate. Such as hole wall copper prickle, residual has been a difficult process. A full row of semi-metallized holes on the edge of such plates PCB, characterized by a small aperture, mostly used on the board, as a subplate of a master plate, through which the semi-metallized holes are welded to the pins of the master plate and components.
If there are copper spines in the semi-metallized hole, when the manufacturer welding, it will lead to the welding foot is not firm, virtual welding, serious will cause bridge between the two pins short circuit. Both drilling and milling, the direction of rotation of the SPINDLE is clockwise, preventing the extension of the metallization layer during processing and the separation of the metallization layer from the hole wall, and ensuring that the copper spines and residues will not be produced after processing. To be larger than the gong empty area.
