GL-Star | SMT Printer

GL-STAR | SMT Printer

Above & Beyond Your Expectation

The Fully Automatic SMT Printer GL-Star features machine vision technology for automatic identification, employing a high-precision servo drive dynamic system to ensure fast and accurate alignment.

Computer control enables effortless adjustment of printing height, squeegee pressure, printing stroke, speed, cleaning cycle, and other printing parameters with just a simple click

The GL-Star is equipped with features such as auto stencil positioning, automatic top clamp & motorized side clamp, and stencil lock. These capabilities help ensure superior printing quality with minimal human intervention.


Back to Back Ready

2 machines back-to-back are perfect match for dual-lane SMT line. Therefore, the internal structure of the GL-Star is pre-assembled in back-to-back configuration. It can be used as a stand-alone unit, or additional equipment can be seamlessly added in a back-to-back mode in future.

Auto Stencil Positioning

The stencil Y position is adjustable via user interface, and the settings can be saved and reapplied when replacing the stencil. This function significantly reduces human errors and saves time in readjusting stencil position.

Stencil Lock

The stencil lock vacuum suction firmly holds the stencil on both sides of the conveyor during printing cycle, eliminating stencil vibration by having firm contact with the PCB.

PCB Clamper

The PCB clamper is a combination of retractable top clamp and motor controlled side clamp, uniquely designed by GKG (patented). With these standard features, all of today’s available and challenging substrates can be securely clamped and print to the highest quality.

Optional Features

Ready for Industry 4.0

Through machine status, parameters can be uploaded automatically. Designed to support customers’ advancement towards Industry 4.0 intelligence production, GL-Star provides seamless connection with users’ MES system, enhancing product traceability and maintenance needs.

SPI Close-loop Connection

With SPI close-loop system, machine will automatically adjust and correct the print deposits based on the feedback given with regards to poor printing quality. This will facilitate improved print quality and production efficiency, by forming a complete printing feedback system.

Paste Rolling Diameter Monitoring System

Tracing solder paste rolling diameter in real time and trigger the auto dispensing if it falls below 10mm. Completely eliminate insufficient solder paste on stencil and keep the paste rolling speed within optimum range to achieve best printing result with this smt printer.

Auto Paste Dispensing

The paste is automatically dispensed across the entire squeegee length, maintaining at 15mm rolling diameter, adopting the common 500 grams’ solder paste jar. Completely eliminates the wastage of solder paste overflowing to the sides of squeegee.

Stencil Aperture Inspection System

Using panel light installed at the top and CCD camera below to inspect stencil apertures. It automatically detects the clogging of stencil apertures to eliminate poor quality stencil being used, ensure quality printing right from the start.
