Silicone rubber key wear test.

Silicone keys in all kinds of fields of equipment are very common, but different fields of silicone keys are not the same requirements, some to light, and some to waterproof, how to design waterproof silicone keys. Silicone itself is waterproof, in order to silicone keys can play a waterproof role, it is necessary to consider from the key structure design. First of all, the key structure can not have positioning holes, once the positioning hole is designed, when the water flows into the key, it is likely to flow from the gap in the positioning hole into the circuit board. Second, the key also needs to design a waterproof edge, waterproof edge refers to the bottom four periphery of the silicone key, design a silicone waterproof wall higher than the bottom thickness of the key, and then according to the shell, circuit board and keys, design a fixed slot on the edge of the waterproof wall (usually semicircular), the position of the fixed slot needs to have a certain distance from the position of the circuit board.

Significance of silicone button wear test:

Silica gel is a kind of highly active adsorption material, which belongs to amorphous substance. The main component of silicone is silica, which is chemically stable and does not burn. Silicone is not only resistant to high temperature but also low temperature, and can be used in a wide temperature range, generally between -40 degrees and 400 degrees. Both chemical properties and physical and mechanical properties change little with temperature. So silica gel is widely used. However, this kind of high-temperature special silicone product material is relatively special in the market is not common, so the cost is relatively high.

Silicone button wear test is good:

Mold problem of silicone products. Mold manufacturers tampered with the structure, so that the products produced only have their shape and no performance. Moreover, the mold material is inferior, and the mold is often repaired during use and cannot reach the predetermined production capacity. In strict accordance with customer product drawing mold.
