    • A screen printing apparatus comprising a screen having an opening or openings of a desired print pattern and having a lower surface being positioned adjacent to a substrate to be printed, and a nonflexible squeegee comprising a cavity for containing a material to be printed on the substrate. The cavity is defined by the interior surfaces of surrounding walls extending generally vertically from the lower extremities at which the squeegee directly contacts the upper surface of the screen. While the squeegee travels with respect to the screen the material to be printed flows from the cavity into the openings of the screen, and thereby onto the substrate. The squeegee may be formed of stainless steel, a ceramic material or a synthetic resin.
    • 一种丝网印刷设备,包括具有所需打印图案的开口或开口的屏幕,并且具有邻近待印刷的基板定位的下表面;以及非柔性刮板,包括用于容纳待印刷材料的空腔。 空腔由围绕壁的内表面限定,该内壁从刮板直接接触屏幕上表面的下端大致垂直地延伸。 当刮板相对于筛网移动时,待印刷的材料从空腔流入屏幕的开口,从而流到基板上。 刮板可以由不锈钢,陶瓷材料或合成树脂形成。
