Preparation of membrane switch before printing

Membrane switch is a widely used accessory in electronic products. Membrane switch belongs to contact switch, which is generally made by printing contact circuit with conductive paste on flexible polycarbonate or polyester film. The film can be divided into touch switch, light touch switch, light touch button, electronic panel, etc. The structure of the membrane switch is relatively simple. It is composed of decorative panels, upper and lower electrode films, and isolation layers. The entire surface is a plane, which is flat and thin. The screen printed membrane switch mainly includes panel printing and circuit printing. In order to ensure the quality of panel printing, the following aspects should be paid attention to.

Prepress preparation According to production practice, the prepress preparation of membrane switch panel screen printing has a great impact on production efficiency and printing product quality. If the prepress preparation is not well done, the production cost will increase.
