Product Description

Fully automatic screen printer designed for high precision screen printing or stencil printing in SMT industry.
2. Product Features:
A)Support PCB sizes from 50mm x 50mm to 400mm x 340mm and PCB thickness from 0.6mm to 6mm.
B)High printing accuracy
1. High positioning accuracy, repeated positioning accuracy ± 0.01mm; Printing accuracy 0.025mm.
2. Support glue printing
C)Automatic control improves production efficiency, quality control and cost saving:
1. Automatic stencil positioning
2. Automatic PCB calibration
3. Automatic adjustment of squeegee pressure
