Membrane key control circuit and manufacture process thereof

Abstract

The invention provides a membrane control circuit which comprises a control chip. The control chip P6 is connected with a display circuit and a key circuit. The control chip, the display circuit and the key circuit form a closed loop. According to the membrane key control circuit, manufacture process, the circuit of a membrane switch on the key is manufactured through an epoxy glass cloth laminate; an isolation layer is pasted on the surface of the circuit board; when specific manufacture is carried out, after the circuit board is assembled, a hot press is used to carry out high temperature heating on the epoxy glass cloth of the circuit board; high temperature bonding is carried out; and finally an isolation layer is closely pasted on the surface of the circuit board. By improving circuit connection and a membrane manufacture method, the hardness of the membrane key is improved.

Description

technical field [0001] The invention relates to the field of modern architecture, including the research, development and improvement of the film production process of the circuit board, and in particular to a control circuit of the film button and the production process thereof. Background technique [0002] With the development of modern architecture, buildings are becoming larger and more complex. When making and processing building circuit key switches, there will be problems with the production of too many LED lights due to the immaturity of key membrane switch technology, which will lead to product yields. On the other hand, making a membrane switch with too large an area will lead to insufficient hardness of the membrane switch, and lead to key locks and key connections during use, seriously affecting the control of the circuit, resulting in an increase in the rate of defective products. [0003] Therefore, a control circuit of a thin film key and its manufacturing pr...

[0002] With the development of modern architecture, buildings are becoming larger and more complex. When making and processing building circuit key switches, it will appear that due to the immaturity of key membrane switch technology, too many LED lights made of membrane switches will lead to product yields. On the other hand, making a membrane switch with too large an area will lead to insufficient hardness of the membrane switch, and lead to key lock and key connection during use, seriously affecting the control of the circuit, resulting in an increase in the rate of defective products
