| abstract |
A method of regenerating an electroless tin or tin alloy plating solution contaiing thiourea or thiourea compounds by reducing impurities by adding organosulfonic acid, organosulfonic acid compound, or salts thereof in certain amounts and then cooling the solution to form precipitates. The precipitates are then removed from the tin or tin alloy solution. |
