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