The aerospace and military field is a special field, and the requirements for products are also quite high. The stability, reliability and durability of the product are of Paramount importance. In addition, it needs to be waterproof, corrosion resistant, UV resistant, able to maintain normal operation in extremely harsh climates,
Such as hot environment, low temperature and high humidity environment, high salinity environment, rainy day, chemical sites, oil pollution environment, high pressure environment and so on. The applications of ships and yachts sailing at sea, aircraft flying in the air and tanks, vehicles, instruments and equipment on the battlefield all require thin-film switch products
With very high reliability and stability. They have their solutions and recommendations for applications in this industry:
1) Film switch, film key products:
1.1) The surface material must be imported PET material with high quality corrosion resistance and UV resistance;
1.2) The whole film switch product structure must meet IP65 or NEMA-4 or higher standards;
1.3) The line part needs to use FPC or PCB lines with higher reliability, rather than PET lines with printed silver lines;
1.4) All openings should be sealed after the film switch is assembled on the client device;
1.5) Make daily inspection, once any functional failure problem is found, new products need to be replaced immediately to prevent potential dangers;
2) Silicone key switch:
2.1) Adopt high-quality imported silica gel raw materials;
2.2) Adopt secondary vulcanization process;
2.3) The silicone button perimeter needs to be designed into a wrapping structure, and the following line part is wrapped inside;
2.4) Use FPC or PCB lines instead of PET lines;
2.5) The surface of the silicone button needs to be treated with PU spray;
2.6) All openings should be sealed after the film switch is assembled on the client device;
2.7) Do daily inspection, once any functional failure problem is found, new products need to be replaced immediately to prevent potential dangers;
The silicone button itself has a good touch and durability, generally speaking, it is not easy to break. End users need to pay close attention to the lower line. Once the line problem is found, it is necessary to replace it with a new product or replace part of the line;
