GL-Star

The GL-Star Fully Automatic SMT Printer is equipped with machine vision technology for automatic recognition and integrates a high-precision servo-driven dynamic system to deliver fast and accurate alignment.

With computerized control, operators can easily fine-tune printing parameters with just one click, ensuring advanced operation. Featuring auto stencil positioning, automatic top clamps, and motorized side clamps, the GL-Star guarantees outstanding printing quality and maximum stability with minimal operator involvement.

STANDARD FEATURES & OPTIONAL FEATURES
Back to Back Ready
Back to Back Ready

Two machines set up back-to-back are the perfect solution for a dual-lane SMT production line. The GL-Star’s internal structure is pre-assembled in a back-to-back configuration, allowing it to function as a standalone unit or to be seamlessly expanded with additional equipment in the future.

Auto Stencil Positioning
Auto Stencil Positioning

The stencil Y-axis position can be easily adjusted through the user interface, with settings that can be saved and reused when replacing the stencil. This feature helps to minimize human errors and greatly reduces the time needed for repositioning.

Stencil Lock
Stencil Lock

The stencil lock with vacuum suction secures the stencil tightly on both sides of the conveyor during the printing cycle. By maintaining firm contact with the PCB, it completely eliminates stencil vibration, ensuring stable and precise printing.

PCB Clamper
PCB Clamper

The PCB clamper, designed and patented by GKG, combines a retractable top clamp with a motor-driven side clamp. With these standard functions, even the most demanding substrates can be firmly secured, ensuring stable clamping and top-quality printing results.

Ready for Industry 4.0
Ready for Industry 4.0

With the ability to automatically upload machine status and parameters, the GL-Star is designed to support the shift towards Industry 4.0 smart manufacturing. It provides seamless integration with MES systems, improving both product traceability and maintenance efficiency.

SPI Close-loop Connection
SPI Close-loop Connection

With the SPI closed-loop system, the machine automatically adjusts and corrects print deposits based on feedback regarding insufficient print quality. This creates a complete printing feedback loop, improving both print accuracy and overall production efficiency.

Paste Rolling Diameter Monitoring System
Paste Rolling Diameter Monitoring System

This SMT printer tracks the solder paste rolling diameter in real time and automatically triggers dispensing whenever it drops below 10 mm. It eliminates insufficient paste on the stencil and maintains the paste rolling speed within the optimal range, ensuring the best possible printing results.

Auto Paste Dispensing
Auto Paste Dispensing

The solder paste is automatically dispensed along the full length of the squeegee, maintaining a 15 mm rolling diameter and using a standard 500 g solder paste container. This process eliminates solder paste waste caused by overflow at the squeegee edges.

Stencil Aperture Inspection System
Stencil Aperture Inspection System

By using a panel light on the top and a CCD camera underneath, the system inspects stencil apertures with precision. It automatically detects clogged apertures, preventing the use of defective stencils and guaranteeing high-quality printing from the very first run.
