The Fully Automatic SMT Printer YSL-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 YSL-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.
2 machines back-to-back are perfect match for dual-lane SMT line. Therefore, the internal structure of the YSL-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.
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.
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.
The PCB clamper is a combination of retractable top clamp and motor controlled side clamp, uniquely designed by YUSH (patented). With these standard features, all of today’s available and challenging substrates can be securely clamped and print to the highest quality.
Through machine status, parameters can be uploaded automatically. Designed to support customers’ advancement towards Industry 4.0 intelligence production, YSL-Star provides seamless connection with users’ MES system, enhancing product traceability and maintenance needs.
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.
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.
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.
