<p>Disclosed is a squeeze apparatus of a screen printer for a printed circuit board. According to the present invention, a width adjust guide member has an inclined surface to guide flow of a solder paste while both lateral sides of a squeeze roller are pressed in both sides of the squeeze roller, and coating is performed from a rolling motion of a squeeze roller to which a pushing pressure is applied when a printing circuit board is coated with a solder paste. The present invention has effects of coating a printing circuit board with a solder paste with a uniform and constant thickness; preventing a pore from being generated in a solder paste with which a printing circuit board is coated from the pushing pressure of a squeeze roller; maintaining the constant coating width of a solder paste with which a printing circuit board is coated at a constant thickness not to generate a pore; and smoothly supplying a solder paste to a pipe type nozzle or a pattern opening in a mask step using a metal mask having a pipe type nozzle or a mask step using a stencil mask having a pattern opening. Therefore, a printing circuit board is more easily coated with a solder paste, thereby the quality of coating a printing circuit board with a solder paste can be improved.</p> |
