Difficulties In Machining Metallized Half-Hole PCB
Metalized half-hole PCB after forming the hole wall copper black , burr residuadeviation has been a difficult problem in the molding process of PCB factoEspecially the whole row of half holes similar to stamp holes , the aperture isabout 0.6 mm , the hole wall spacing is 0.45 mm , the outer figure spacing is 2mm , because the spacing is very small , it is easy to cause short circuit because of copper skin.
The general metallized half-hole PCB foming methods are CNC millingmachine gongs , mechanical punching machine punching , V-CUT cutting and so on , these processing methods in removing the need for part of the hole tomake copper , can not will lead to the remaining part of the PTH hole section of.
Why Increased Costs For Half-Hole PCBs
Half hole is a special process, in order to ensure that there is copper in the hole, it is necessary to do half of the process before the edge, and the general half hole PCB is very small, so the general cost of half hole plate is relatively high.
