PURPOSE:To prevent a thin printed circuit board from bending at the time of vertically charging into a tank liquid by forcibly bending slightly inward the substrate to be processed when the substrate is vertically charged into the liquid. CONSTITUTION:After a thin printed circuit board 1 is held by a pair of grips 2, the substrate 1 is bent by contracting the grips on a slide rail 3. As a result that the substrate is vertically charged into a chemical processing tank while this state is being held, the substrate is not bent in the chemical, and not brought into contact with the tank wall, thereby providing a satisfactory result. |
