How selective PCB wave soldering equipment?

In recent years, the utilization rate of PCB components has been rising, and even accounts for about 95% in some mixed assembly electronic products. For the welding of mixed assembly circuit board, according to the previous ideas, the plan of resoldering circuit board A surface and then wave soldering B surface has been faced with challenges.In mainly integrated circuit products, it is difficult to guarantee the B side resistance temperature only pasted on the SMT components, worse under high temperature, not pasted on the possible damage caused by wave soldering SMT components, if use manual welding method for a small amount of THT components, and feeling to sex is difficult to guarantee.To solve the above problems, selective wave soldering equipment appeared in PCB industry.The device works by moving small wave solder slots and nozzles to the spot where the circuit board needs to be soldered, sequentially and quantitatively spraying flux and spurting solder peaks, and locally soldering, under the control of a program that converts circuit board design files.Selective wave soldering is mainly used for patch welding or welding of mixed circuit boards with few components.Selective wave soldering can realize local welding and effectively avoid thermal damage to SMT components in the welding process of mixed circuit board.
