Abstract

Embodiments of the invention discloses a PCB (printed circuit board), a PCB processing method and an electronic device. The PCB processing method can comprise: processing a hole on the 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 being provided with a geoelectrical layer thereon and the metal base being fixedly arranged in a groove provided on the base materials, and 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 so as to switch on the inner layer of the geoelectrical layer and the metal base. The scheme of the embodiments of the invention is favourable to improving the reliability of connection between the geoelectrical layer and the metal base of the PCB and improving the transmission performance of a high-frequency signal.

Description

technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to a method for processing a printed circuit board, a printed circuit board and electronic equipment. Background technique [0002] At present, there are many types of printed circuit boards (PCB, Printed Circuit Board), and their application range is extremely wide. In high-frequency and high-speed PCBs, the metal base embedded in the PCB is mainly grounded through the conduction with the inner ground layer of the PCB. [0003] In the prior art, the metal base and the inner ground layer are connected through wires. Practice has found that although the existing connection method connects the ground layer and the metal base, the reliability of this connection method is poor, and it is often prone to disconnection; and the transmission performance of high-frequency signals is unstable. Contents of the invention [0004] Embodiments of the present invention provid...
