High-frequency heating core: High-frequency heating core is a heating core widely used in China. Its heating method is pulse heating, that is, laser welding machine ，during the welding process of the automatic soldering machine, the heating method of the soldering iron is transmitted in the form of pulses.
Ceramic heating core: The ceramic material is relatively high temperature resistant and has good temperature control, but the temperature return is relatively slow, which will affect the welding quality and efficiency to a certain extent.
DC heating core: The DC heating core is made of sterling silver, which directly heats and releases heat. Even sensitive components will not cause any damage to the heating core.
