If you want to know what lead-free wave soldering is, you must first understand how lead-free wave soldering works. The welding mechanism of lead-free wave soldering is to use the molten liquid solder to form a solder wave of a specific shape on the liquid surface of the solder tank with the help of a power pump, and place the PCB with components inserted on the conveyor belt, through a certain angle and A certain immersion depth passes through the solder wave crest to realize the process of solder joint welding.
There is no difference between lead-free and lead-free for the new wave soldering machine that has just left the factory. It is only distinguished when you use it. Generally, there is a mark on the lead-free wave soldering machine, which is the internationally accepted “pb”, which is the lead-free mark. Leaded or lead-free wave soldering machine, there is no difference in appearance (mainly depends on whether leaded tin or lead-free tin is used) mainly depends on whether the produced PCB contains lead. Lead-free wave soldering can directly produce leaded PCBs. If leaded PCBs are converted to lead-free again, the tin bath must be cleaned and replaced with lead-free tin materials before production.
