High Precision Automatic Screen Stencil Printer (JL-1200)

JL-1200 is a high precision automatic screen stencil printer designed for high precision steel mesh printing or stencil printing in SMT industry.

Wide compatibility for PCB dimensions from 50mm x 50mm to 1200mm x 340mm and PCB thickness from 0.6mm to 6mm.
High printing resolution:
High positional accuracy, repeated positioning accuracy ± 0.01mm; Printing accuracy 0.03mm.
Support glue printing
Automatic control improves production efficiency, controls quality and saves production cost:
Automatic stencil positioning;
Automatic PCB alignment;
Automatic adjustment of squeegee pressure;
Automatic printing;
Automatic stencil cleaning (dry-type, wet-type);
Adopt company independently developed suspended print head and programmable automatic pressure adjustment system with pressure closed-loop feedback. Support on-line real time pressure feedback and automatic squeegee pressure balancing. Accurate pressure control ensures perfect paste forming effect.
Programmable motor controls separation speed and stroke between squeegee and stencil, to realize multi-method demold.
Multi-functional PCB fixed positioning system, for convenient and accurate PCB positioning.
Upward and downward visual positioning.
Built-in image processing system;
Support 2D, SPC functions.
