What are the three general types of automatic soldering machine heater cores?

I. High-frequency Heater Core: High-frequency heater is more commonly used in China. Its heating mode is pulse heating, that is, in the automatic soldering machine welding process, the soldering iron's heating mode is spread by the form of pulse. Therefore, the pulse in the welding process will have a certain impact on the welding product. Welding process requirements, high product quality, and the presence of sensitive components can not take this heater core for welding.

II. Ceramic Heater Core: Ceramic material is more resistant to high temperatures, with good temperature control. But the temperature return is relatively slow, which will affect the welding quality and efficiency to a certain extent.

III. Direct current heater core: the direct current heater core is pure silver material, with direct heat release mode, even if it is a sensitive original, this kind of heater core won't cause any damage to it.
