Abstract

The invention relates to a printed circuit board, a printed assembly board and electronic equipment, and the printed circuit board comprises an insulating substrate, an operation part bonding pad printed on the insulating substrate, a ground plane printed on the insulating substrate, and a protection layer covering the ground plane. The operation part bonding pad is a bonding pad used for being connected with an operation part receiving external triggering; and the protection layer forms a window beside the operation part bonding pad, so that the ground plane is exposed outwards at the window.

Description

technical field [0001] The present disclosure relates to the technical field of circuit board design, and more specifically, to a printed circuit board, a printed assembly board, and an electronic device provided with the printed assembly board. Background technique [0002] For most electronic devices, such as smart speakers, smart phones, etc., there are operating components such as physical buttons for users to operate to achieve setting functions. In order to provide users with operable operating parts, corresponding openings need to be provided on the housing of the electronic device, so that the operating parts can be exposed to the outside through the corresponding openings. Create gaps. Therefore, when the user operates these operation parts, static electricity just is easy to beat to the circuit board that connects this operation part from the gap, and then causes the permanent damage of electronic components and parts. [0003] In order to solve the above static ...
