Cycle One cycle allowed to be dipped in solder including plastic mold portion. Flux Rosin flux containing small amount of chorine (The flux with a maximum chlorine content of 0.2 Wt % is recommended.) (2) Cautions Fluxes Avovid removing the residual flux with freon-based and chlorine-based cleaning solvent. 2.Cautions regarding noise Be aware that power is suddenly into the componment any surge current may cause damage happen, even if the voltage is within the absolute maximum ratings.
