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