Problems needing attention in daily life when using light touch switch

What problems should we pay attention to when we touch the switch in our daily life? What are the details we need to pay attention to? Let's give you a detailed introduction.
When using the tap switch, pay attention to the following items. When welding the terminal, the tap switch will impose load on the terminal, which may cause looseness, deformation and reduction of electrical characteristics according to different conditions.
Pay attention to the following items when using the switch with light touch:
1. When lightly touching the switch to weld the terminal, apply load to the terminal, which may cause looseness, deformation and reduction of electrical characteristics according to different conditions.
2. Because the water-soluble flux may corrode the switch during welding, please avoid using it.
3. Please set the conditions for light touch switch welding according to the conditions of actual batch production.
4. When soldering tin twice, please do it after the first part of soldering is restored to normal temperature. If heating continuously, it is possible to deform the periphery, loosen and drop the terminals and reduce the electrical characteristics.
5. Please do not let flux flow from around the PCB to the switch.
6. After installing the switch, in order to make the binder of other parts harden, please contact us when passing through the regenerative hardening furnace.
7. When using through-hole printed circuit boards and circuit boards other than those recommended, due to the influence of thermal stress, please fully confirm the welding conditions in advance.
8. With pin type, please weld at pin position. If welding is carried out when the pin midpoint is fixed, the pin mechanism may be deformed.
9. It cannot be cleaned. When the terminal is welded, the load is applied to the terminal, which may cause looseness, deformation and reduction of electrical characteristics according to different conditions.
