The process of making a silicone switch involves several steps.
Silicone switch is a kind of switch for membrane keyboard, because of its soft texture and durability, it is widely used in many occasions. Silicone switches are usually composed of two parts: a silicone button and a conductive film are used together. The silicone button triggers the switch action through pressure, while the conductive film contains a series of wires and PCBA links, usually designed to connect or disconnect each other to control the operation of electronic devices.
The production process of silicone switch can be divided into the following steps:
1: Design The first step in making a silicone switch is to design it. Design includes button shape, size, interaction, and board architecture and layout. This process is usually done by designers using computer-aided design software (CAD) to ensure the consistency and reliability of the appearance of the silicone switch and the internal circuit.
2: Once the design is done, the next step is to make the molds that will be used to make the silicone switches. Dies are usually made of steel or aluminum and are cut and engraved using an EDM machine. The mold compresses the silicone into the required shape and size, and divides it into button shapes and wire interfaces that conform to the circuit board.
3: Gluing refers to applying liquid silicone on the mold to ensure that the silicone can completely fill the space in the mold and maintain the desired shape and size. Glue application is usually performed using automatic coating robots to ensure uniformity and speed of coating, and to reduce the formation of air bubbles. A good gluing process can avoid bubbles and defects in silicone switches.
4: Silicone infusion After the glue coating is completed, the coated mold will be infused with silicone on a special silicone infusion machine. Silicone infusion is to inject liquid silicone into the mold coated with glue, seal the air and fill the space, and then let the silicone solidify. Silicone perfusion is usually performed under vacuum or low pressure to reduce the generation of air bubbles. The process of silicone perfusion can accurately control the distribution of silicone and ensure the high quality of silicone switches.
5: Silicone switch surface treatment The surface of the silicone switch usually needs to be treated to increase its wear resistance, high temperature resistance and water resistance. For example, a special coating or rubber oil can be coated on the surface of the silicone to increase its waterproof and wear resistance. Surface preparation of silicone switches needs to be done early in the manufacturing process to ensure paints and coatings can evenly cover the silicone button and circuit board surface.
6: Circuit board processing Adding wires and components between the silicone button and the circuit board requires circuit board processing. Circuit board processing can include drilling, etching and soldering. In this process, workers glue components such as wires, resistors and capacitors to the circuit board, use a drill to drill holes, and clean the circuit board with etching solution. Once complete, workers can machine the finished circuit board into the silicone switch for easier installation.
7: Silicone switch assembly When the button and circuit board of the silicone switch are ready, the next step is to assemble them in the mold. The silicone buttons will fit on the board and hold the board in place in the mold. Silicone can then be injected to hold the button and circuit board together firmly. When injecting the silicone, you need to make sure that the circuit board and all the leads are in the normal and correct direction and position in the option of the silicone switch.
8: Silicone switch test After the silicone switch has been successfully assembled, it needs to be tested to ensure that it works properly. Silicone switches are usually tested for a long time and verified by the owner to ensure their quality, and are produced in strict accordance with the engineering design requirements. Silicone switch testing can include various means such as electronic testing, physical testing and environmental testing to ensure reliable performance of silicone switches.
The manufacture of silicone switches requires multiple steps and requires rigorous design, precise manufacturing and rigorous testing to ensure that the manufactured silicone switches have good performance and meet the design requirements. During the manufacturing process, each step needs to be handled carefully to ensure the precision and reliability of the silicone buttons and circuit boards, and rigorous testing and verification are carried out to ensure the quality and reliability of the silicone switches.
