Will the conductivity of silicone buttons affect their service life?

There are generally two ways for conductive silicone buttons to conduct electricity. One is to apply conductive adhesive to the bottom where conductivity is required to achieve conductivity. The other is to combine with conductive black particles during the molding process. The main reason for poor conductivity of silicone buttons is that the conductive black particles do not adhere to the button properly. So, what causes this phenomenon.

The quality control points for silicone buttons are quite professional. In the early stage of mold development, it is necessary to control the strength of the mold. Experienced mold engineers know that the elasticity and feel requirements of silicone buttons are the most stringent for customers. Moreover, if the silicone mold is not well controlled during mold opening, it will be time-consuming, labor-intensive, and costly to modify and repair the mold in the later stage. We have our own mold room, and mold engineers are very familiar with the development process of silicone button molds. This is also an advantage in customizing silicone buttons, as they can think of unexpected aspects for customers and greatly shorten the project mold opening time.

A perfectly flawless silicone button needs to go through the hands of more than N people before leaving the factory. The editor works on the workbench in the factory and quality inspection workshop every day, and there are endless inspections of silicone buttons. The quality requirements for silicone buttons are the strictest, basically finding high-quality products from good ones. The quality inspection supervisor arranges inspectors for silicone buttons who are also experienced employees for many years. They are familiar with the common defects and abnormalities of silicone buttons, which greatly improves work efficiency and reduces the outflow of defective products.

One is the vulcanization temperature. If the vulcanization temperature of silicone buttons is too high or too low, it will cause the conductive black particles to fail to bond with the silicone or the conductive black particles to fall off.

Secondly, if the vulcanization time is too long or too short, it can also lead to incomplete vulcanization of conductive silicone buttons, resulting in black particles falling off.

Thirdly, during the molding and vulcanization process, poor exhaust of the product can lead to black particles falling off or poor air circulation.

Finally, during the molding process of silicone raw materials, if the pressure of the molding machine is too low or the amount of raw materials is too small, it can also cause the conductive black particles to fall off. The conductive black particles of silicone products are the key to the conductivity of silicone keys, and poor bonding or falling of black particles with silicone keys can lead to poor conductivity.

The light leakage of laser engraved buttons is mainly due to two reasons: thin spraying and deep laser engraving.
Let's first understand what spray coating is. Before laser engraving, silicone buttons need to be sprayed with ink to cover the surface of the button and form a closed light shielding. It sounds simple, but in reality, it is difficult because some buttons need to be sprayed 3-4 times to completely block the light. Insufficient or uneven ink spraying can easily lead to light leakage.

Laser engraving deep is easier to understand. Laser engraving is the process of carving patterns on an ink coating using a laser. The depth of laser engraving can be controlled, and if the engraving is too deep, it will pierce through the layers that do not need to be engraved.
