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 circuitbecause of copper skin.
The general metallized half-hole PCB foming methods are CNC millingmachine gongs , mechanical punching machine punching , V-CUT cutting andso 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.
Reasons for increased costs for half-hole PCBs
Half hole is a special technological process , in order to ensure that tcopper in the hole , we must do half of the process when the gong edgethe general half hole plate is very small , so the general cost of half hole plate is relatively high.
