由高精度的图像视觉系统精确识别并计算出PCB Mark与钢网Mark间的偏差值，由PC控制工作台完成校准;在印刷锡膏时，锡膏受刮刀的推力产生滚动的前进，所受到的推力可分解为水平方向的分力和垂直方向的分力。当运行至模板窗口附近，垂直方向的分力使粘度已降低的锡膏顺利地通过窗口可印刷到PCB焊盘上，当平台下降后便留下精确的锡膏图形。

The deviation between PCB Mark and steel Mark is accurately identified and calculatedby the high-precision image vision system, which is controlled by PCB Make the platformto complete the calibration; When printing solder paste, the solder paste is pushed by thescraper to produce rolling forward, and the thrust received can be decomposed intoThehorizontal component and the vertical component. When running near the template windowthe vertical component reduces the viscosityThe solder paste can be printed on the PCB padsmoothly through the window, and the precise solder paste pattern will be left after the platform drops
