- [Company News]Selective wave soldering advantage2019/11/11/ 15:20
- Selective wave soldering is a special form of wave soldering invented to meet the requirements of modern welding processes. It also has three main components of flux unit, preheating unit and welding unit. Through pre-programmed procedures, the machine can be sprayed and welded in a targeted manner. The welding efficiency and reliability are higher than manual welding, and the welding cost is lower than wave soldering.
