Problems solved by technology

[0002] With the development of the electronic industry and the wide application of integrated circuits and polymer materials, the harm caused by the force, discharge and induction of static electricity is very prominent. The damage caused by the hazard is immeasurable, and the electronic equipment we usually use is equipped with some buttons for easy operation. These buttons are generally electroplated, resulting in static charges often jumping into the electronic equipment from the active gap between the button and the electronic device casing inside the circuit board, causing circuit board failure

Abstract

The invention relates to a key assembly matching with a circuit board, which comprises pads made of anti-static materials. The pad is flanged and is covered on the circuit body, and the flange wraps the edge of the circuit body. In addition, the invention further provides an electronic device using the key assembly.

Description

technical field [0001] The invention relates to a key assembly and electronic equipment using the key assembly. Background technique [0002] With the development of the electronic industry and the wide application of integrated circuits and polymer materials, the harm caused by the force, discharge and induction of static electricity is very prominent. The damage caused by the hazard is immeasurable, and the electronic equipment we usually use is equipped with some buttons for easy operation. These buttons are generally electroplated, resulting in static charges often jumping into the electronic equipment from the active gap between the button and the electronic device casing internal circuit board, causing circuit board failure. Contents of the invention [0003] In view of this, it is necessary to provide a key assembly that can prevent static electricity and an electronic device using the key assembly. [0004] A button assembly matched with a circuit board, which in...
