PRINTED CIRCUIT BOARD PROCESSING METHOD, PRINTED CIRCUIT BOARD AND ELECTRONIC DEVICE

摘要

A PCB, a PCB processing method and an electronic device. The PCB processing method may comprise: processing a hole on a PCB, wherein the PCB comprises a metal base and at least two layers of base materials, at least one layer of base material from the at least two layers of base materials has a geoelectrical layer thereon, and the metal base is fixedly arranged in a groove provided on the base materials, the processed hole contacting both the geoelectrical layer and the metal base; and arranging a conductive substance in the hole, the conductive substance in the hole contacting the inner layer of the geoelectrical layer and the metal base to switch on the inner layer of the geoelectrical layer and the metal base. The solution of the embodiments of the present invention is favourable to improving the reliability of connection between a geoelectrical layer and a metal base of a PCB and improving the transmission performance of a high-frequency signal.
