Difficulties In Drilling Heavy Copper PCBs
With the increase of the copper thickness, the thickness of the heavy copper PCB also increases. heavy copper PCB is usually more than 2.0mm thick, drilling production due to the thickness of the thickness of the plate and copper thick factors, production is more difficult. In this regard, the use of a new cutter, reduce the service life of the drill cutter, section drilling has become an effective solution to the heavy copper PCB drilling. In addition, the optimization of drilling parameters such as feed speed and rewind speed also has a great influence on the quality of the hole.
The problem of milling target holes. During drilling, the energy of X-Ray gradually decreases with the increase of copper thickness, and its penetration capacity reaches the upper limit. Therefore, for PCB with thick copper thickness, it is impossible to confirm the deviation of the head plate during drilling. In this regard, the offset confirmation target can be set at different positions of the plate edge, and the offset confirmation target is first milled out in accordance with the target position in the data on the copper foil at the time of cutting, and the target hole on the copper foil and the inner layer target hole are produced in accordance with the lamination.
