1. What is Screen Printing Machine?
The screen printing machine is used to dispense solder paste on the lands of a
printed circuit board through the silk-based stencils.In addition, it is equipped
with a two-camera calibration system for PEC and stencil recognition and a high
rigidity mechanism, enabling high precision printing.

Note
The contents described in the instruction manuals are based on "PCB Transfer
Reference: Front Side of Machine" and "PCB Flow Direction: From Left to
Right".
The PCB transfer reference and the PCB flow direction differ, depending upon
the selected model.
