For the introduction of welding method of patch light touch switch, what is the advantage of this welding method? Now I will give you a detailed introduction.
The manufacturer of patch light touch switch introduced that reflow welding normally consists of 7 stages of temperature process. The switch should cooperate with the production process, and the material of the product should also meet the requirements of the 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 kind of machine suction process. The lead of the switch must be flat, the pin must be able to eat tin, and 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.
Benefits of reflow welding:
1. In reflow soldering technology, solder is only used once, and there is no reuse. Therefore, solder is very pure and has no impurities, which guarantees 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.
2. When reflow soldering technology is used, it is not necessary to immerse the printed circuit board in the molten solder, but to complete the welding task by local heating. Therefore, the welded components will be subjected to less thermal shock and will not be damaged by overheating.
3. The welding technology only needs to apply solder at the welding site and complete the welding by local heating, thus avoiding welding defects such as bridging.
Above is the introduction of the advantages of the welding method of patch light touch switch.
