GKG-GSE Automatic SMT Stencil Printer for High-Precision Solder Paste Printing
GKG GSE Automatic SMT Stencil Printer
The GKG GSE is a fully automatic SMT stencil printer designed for accurate, repeatable solder paste deposition before component placement. It combines vision alignment, servo-controlled printing, programmable stencil separation and automatic underside cleaning in a compact platform for PCB assembly lines.
With a stated printing accuracy of ±0.025 mm and repeat positioning accuracy of ±0.01 mm, the GSE is intended for manufacturers that need tighter process control without moving to an oversized printing platform. It processes PCBs from 80 × 50 mm to 400 × 340 mm and supports multiple conveyor directions, making it suitable for new lines as well as selected line-upgrade projects.

Main Advantages of the GKG GSE Stencil Printer
Vision Alignment for Repeatable Registration
A digital camera views the PCB and stencil fiducials through upward and downward imaging. The system calculates the alignment correction before printing, helping maintain registration when product models or stencil frames are changed.
Independently Motorized Print Heads
The suspended print-head structure uses two independently driven heads. Squeegee speed, pressure and stroke are controlled through the machine software, allowing the process to be adjusted for different solder pastes, stencil apertures and PCB layouts.
Closed-Loop Squeegee Pressure Control
Squeegee pressure is software-controlled from 0 to 10 kg, with pressure feedback visible to the operator. Stable pressure across the printing stroke helps reduce variation caused by manual adjustment.
Programmable Stencil Separation
Stencil separation speed can be programmed from 0.1 to 20 mm/s. This is useful when fine apertures, dense layouts or different solder paste characteristics require a controlled release instead of rapid separation.
Dry, Wet and Vacuum Cleaning
The underside cleaning system supports dry, wet and vacuum modes. Cleaning sequences and intervals can be programmed according to the PCB and stencil condition, helping remove paste residue before it begins to affect subsequent boards.
Flexible PCB Support and Clamping
Magnetic pins, side supports and an optional flexible automatic pin system are available for board support. Elastic side clamping, vacuum nozzles and the adjustable Z table help secure different PCB sizes and reduce movement during printing.
Where the GKG GSE Fits Best
The GSE is suited to electronics factories processing boards up to 400 × 340 mm, particularly where floor space, repeatability and straightforward product changeover are important. Typical applications include:
- Consumer electronics and smart-device PCB assemblies
- Industrial control boards
- LED lighting and display products
- Communication and networking electronics
- Power supply and inverter boards
- Automotive electronic modules
- Medical and laboratory electronics
- High-mix contract manufacturing
- Prototype and medium-volume SMT production
Final suitability depends on board thickness, component density, stencil design, paste type and the required production takt time.
