Hoki No Clean Liquid Flux 100ml Low-Power RS-422 Transceivers Brown for these 4M7 resistorsTo help the molten solder flow and generate a high quality solder joint, liquid soldering flux is applied to the circuit board assembly. The liquid flux dissolves oxides from metal surfaces, allowing solder to be used to link them together. Hoki No Clean Liquid Flux is a low activity halogen free organic liquid solder flux. It's a no clean flux with a low solids content that doesn't leave residue behind. Even without cleaning, solder junctions appear
