Semi Auto Printer LY-3050 – an advanced printer designed for precise solder paste application
The Semi Auto Printer LY-3050 is a professional device used in SMT surface-mount assembly processes, designed to provide stable, repeatable and fully controlled solder paste deposition on PCB boards. This demo model has only cosmetic scratches, while maintaining full functionality and technical parameters, making it an efficient solution for prototype lines, small-batch production and training environments.
PLC control and advanced touch panel
The device uses a control system based on a microcontroller PLC, which enables smooth operation of the entire mechanism and quick access to process parameters. The intuitive touch panel allows the operator to enter settings, save printing profiles and operate the printer ergonomically. As a result, the printer ensures both high process repeatability and easy adaptation when switching production tasks.
Precise PCB alignment and quick tooling replacement
The LY-3050 is equipped with mechanical alignment arms and precise rotary knobs that allow accurate positioning of the PCB relative to the stencil. This solution minimises positioning errors and increases printing accuracy to 0.02 mm, with repeatability also at 0.02 mm. The print head, which rotates 45°, provides immediate access to the stencil and squeegees, facilitating maintenance as well as quick installation and removal.
Process stability and full control of the squeegee speed
The adjustable throttle allows the operator to precisely set the squeegee speed, eliminating vibration and ensuring even pressure across the entire printing surface. The printer supports boards with maximum dimensions of 300 × 500 mm, while its working area of 320 × 500 mm makes it a versatile choice for various projects. Compatibility with 470 × 370 mm and 650 × 550 mm frames enables the use of a wide range of production stencils.
Operator safety and high work ergonomics
The safety system requires simultaneous pressing of two buttons, preventing accidental activation of the mechanics and protecting the operator from contact with the squeegees and stencil. The device meets energy-saving and stability requirements, consuming power efficiently and appropriately for long-term operation.
