How to prolong the service life of the copper nozzle when using a handheld laser welding machine?
The new copper nozzle of the handheld laser welding machine should be dipped in tin before use. After the power is turned on, the color of the copper nozzle will change for a while, which proves that the copper nozzle of the handheld laser welding machine is hot, and then put solder wire on the tip of the copper nozzle to plate Tin, so that the copper nozzle is not easy to be oxidized. In use, keep the tip of the copper nozzle clean, and ensure that there is always solder on the tip of the copper nozzle.
When using the copper nozzle of the hand-held laser welding machine, if the temperature of the copper nozzle is too low, the solder cannot be melted, or the solder joints will not be completely melted to form an unattractive and unreliable appearance. If the temperature is too high, the copper nozzle will be "burned" (although the temperature is high, it cannot be dipped in tin). In addition, the welding time must be controlled. If the copper nozzle stays for too short a time, the solder is not easy to completely melt, forming a "virtual solder joint". ", and the soldering time is too long and it is easy to damage the components, or make the copper foil of the printed circuit board warp. A solder spot needs to be soldered every two seconds. If it is not completed, I would rather wait a while and solder again.
