Water-soluble flux 703 Application

➤ The service life of soldering flux varies slightly due to process conditions. When the flux is not in working condition, it should be kept in a sealed container as much as possible to avoid solvent evaporation.

➤ When it is necessary to replace expired flux, the flux container should be thoroughly cleaned before replacing with a new flux.

➤ Pre heating after application of flux can fully leverage the advantages of Heming 703 lead-free water-soluble flux. It is recommended that the preheating temperature should reach 100-150 ℃ on the PCB board or component welding surface after preheating.

➤ Using hot water at 50-60 ℃ combined with spray/ultrasonic cleaning can achieve the minimum ion residue without the need for any cleaning agent.
