Because the silicone material itself is insulated. Generally speaking, silicone keys are divided into direct contact with the circuit board to generate signals, and there are two kinds of signals generated by contact with the pot chip. The silicone keys that directly contact the signal need to be able to conduct electricity with the contacts of the circuit board. There are generally two methods for such conductive columnar contacts. One is to apply conductive glue to make it conductive effect. The other is to install conductive black particles. But after the silicone molding, the installation of small conductive black particles is very troublesome. In general, we use the conductive black particles on the silicone mold during molding, so that it is directly pressed into a whole with the silicone key.
Silicone keys in the molding time, in the raw materials to add a certain proportion of the fluorescent powder to make the keys can emit yellow green fluorescence in the dark, the character glow how to do it? This requires fluorescent ink, in the silicone printing ink to add a certain proportion of fluorescent powder, so that it can achieve the effect of fluorescence in the dark. Adding fluorescent powder will not affect the wear resistance of the product. In the anti-alcohol wiping test, it can withstand 3000 times of 500g weight, and the wear resistance effect is very good!
The luminous keys are self-luminous keys at night or in dark places, and the common luminous keys are yellow-green. However, today Xiaobian will show you another process that can make silicone key characters shine. The specific method is to reserve the position of conductive black particles when making the mold, install the black particles with a black particle jig, put them into the silicone molding mold in a unified way, and then carry out molding. Conductive black particles and silicone keys become a whole.
