What is Castellated hole ?
With the growth of the demand of the terminal application market, the global PCB industry is developing constantly, among which the PCB Castellated hole processing technology is one of the key development directions. PCB board Castellated hole, also known as stamp hole in the PCB industry, can be directly welded to the hole side and the main side, which can save connectors and space, and is widely used in signal circuits, like as wifi modules, bluetooth modules, etc.
Castellated hole PCB Circuit Boards manufacturing process
In the manufacturing process of PCB Castellated hole board, routing CNC technology is the most important process, and the phenomenon of copper wire flapping and copper skin warping often occurs in the process of CNC, which causes great difficulties to the manufacturing of half-hole board.
At the same time, there will be two times for CNC routing, namely rude CNC and precise CNC, in the production process of the whole PCB Castellated hole plated. The two routing process are to protect the copper wire in the Castellated hole plated and ensure its quality, but the manufacturing process is relatively various, which greatly affects the production efficiency of PCB Castellated hole plated.
