What happens when the switch can't be switched on during welding and can't be switched on? Let's give you a detailed introduction.
Since the toggle switch has just been purchased, why has it been pressed after the reflow soldering of the production line? Recently, the demand has been raised to switch the peak season.
Toggle the switch with the circuit board, and the pins will be solder paste. If the deviation is too large, it will cause the solder paste to flow into the inside of the switch. If the solder paste runs to the inside of the switch, it will affect the distance between the keys of the switch, which will lead to no press. Some gases will volatilize to the gap between the cover and the hardware of the switch. Many of the reasons are that the power of the SMD exhaust system is too small to cause it to disappear. The method of volatilization, we should pay attention to increase the power, in order to make the gas quickly discharged, to avoid penetration into the switch interior. Some inexperienced SMD vendors often have flux problems, such as some mature SMD vendors know how to control. In fact, this is not the problem of the switch itself.
。 The main characteristic parameters and configuration of some switching switches are listed be
