Abstract
Disclosed is a squeeze for a screen printer. The present invention provides a squeeze for a screen printer, which coats a printed circuit board with an adhesive paste while moving parallel over a metal mask on the printed circuit board, the printed circuit board being open through an opening of the metal mask, the squeeze including a solvent storage unit for storing solvents; and solvent discharging holes for discharging the solvents, stored in the solvent storage unit, to an adhesive paste. Accordingly, the squeeze for a screen printer of the present invention may be useful to prevent a dog ear phenomenon, namely that an adhesive paste layer is asymmetrically formed in an indented manner, by controlling a viscosity of an adhesive paste by discharging a solvent onto an adhesive paste layer that comes in contact with the squeeze when the adhesive paste layer is formed in the printed circuit board.
