The light touch switch generally uses the patch form, in the product material and type as well as the scope of use to give you a good introduction.
Because this product belongs to the patch form, it is very suitable for reflow welding operation. The advantages of reflow soldering: 1) When reflow soldering technology is used, the printed circuit board is not immersed in the molten solder, but is heated locally to complete the welding task; therefore, the welded components are subjected to less thermal shock and will not be damaged by overheating. 2) In welding technology, welding defects such as bridging are avoided because only solder is applied at the welding site and local heating is needed to complete the welding. 3) In reflow welding technology, solder is only used once, there is no reuse, so the solder is very pure, no impurities, to ensure the quality of solder joints. The patch light touch switch combined with reflow welding process can improve production efficiency, reduce labor costs, low product defect rate and save costs. The patch type switch must be packed with carrier tape, which can improve the sealing and preservation of the product.
Material requirements of products:
Reflow welding normally consists of 7 stages of temperature process. Switches should cooperate with production process, and the material of products should also meet the requirements of production process. The highest temperature point of reflow welding is 260 degrees. The plastic material of the switch should also reach 260 degrees to ensure its inherent temperature resistance. Reflow soldering is a machine suction process. The lead of the switch must be flat, the pin must be able to eat tin, the pin can not be oxidized, so the solderability of the product must be ensured. The material of switch pin is best plated with copper and silver, and the plating is better than 0.3um.
Types of products:
Our products are diversified and different types of products are developed according to different use environments and different use structures. Patch type: ultra-thin patch type, side-by-side patch type, waterproof patch type, patch with bracket type, patch with lamp type, patch with dust-proof type and other forms of products.
The scope of application of the product:
Medical equipment, smart watches, tablets, wearable equipment, digital products, color TV, black and white TV, audio equipment, video recorders, cameras, computers, game machines, fax machines, walkie-talkies, batons, machine tool control devices, copying, printers, electronic instruments, instruments and other household appliances.
