Abstract
A print circuit board is demarcated with arbitrary areas. The print circuit board at one area is partly sucked and fixed on an alignment stage. After alignment with a mask, a pattern of the mask is transferred to the board. Next, shift is made to another area to repeat the same operation, thereby sequentially exposing all the areas to light.
