Abstract

PURPOSE: Solder exfoliation electrolyte, obtained by using phosphoric acid solution added anion fluorinated hydrocarbon compound and made the solder exfoliation condition uniform and also, able to easily confirm the end of exfoliation.
CONSTITUTION: Phosphoric acid for industrial use is used for the phosphoric acid and concentration in exfoliation electrolyte is 0.001% or more. FC-95 or FC-98 etc. is used for anion fluorinated hydrocarbon compound and the concentration in the electrolyte is 0.005% or more. Electrolysis for solder exfoliation is carried out at a normal temperature of 15W25°C and current density of 5W10A/cm2.
