Semiauto Stencil Printer

A semi-automatic steel mesh press is a device used in the electronics manufacturing industry, primarily for printing solder paste or glue on printed circuit boards (PCBS) for subsequent surface mount technology (SMT) processes. Compared with fully automatic printing machines, semi-automatic steel mesh printing machines require manual participation in some operations, such as PCB placement and removal, but their core printing process is automatically completed by the equipment.

Manual Solder Paste Stencil Printer

This machine is mainly designed for requirements of single or double-sided circuit board solder cream or red glue printing:
Universal honeycomb plate, movable thimble, movable supporting block, flexible positioning PCB, convenient to print double-side PCB. IThe base uses thick plate and forming welding, strong solid and wear well. Circuit board positioning adopts positioning needle, fixed rod and fixed plate for positioning, which can ensure convenient positioning and accuracy of repeated operation. Make ready mode is made through stencils movement and combined with fine adjustment and correction of X and Y axis in printing platform, which is convenient and quick. Steel mesh stent

The main components of the semi-automatic steel mesh press include steel mesh, printing head, PCB positioning system, visual alignment system, control system, and frame and base. The steel mesh is the core component of the equipment, usually made of stainless steel, with holes corresponding to the PCB pad for the precise distribution of solder paste or glue. The printing head consists of a scraper for evenly printing solder paste or glue onto the PCB pad through the holes in the steel mesh, usually equipped with two scrapers to ensure an even distribution of solder paste. The PCB positioning system consists of a fixture or vacuum adsorption platform that holds the PCB in place and ensures that it does not move during printing, while being equipped with a fine-tuning function to precisely align the PCB with the steel mesh. Some high-end equipment is also equipped with a visual alignment system, through the camera to identify PCB and steel mesh mark points, to achieve high-precision alignment. The control system is used to set printing parameters, such as scraper pressure, printing speed, release speed, etc., usually equipped with a touch screen or digital control panel, easy and intuitive operation. The frame and base are used to support the steel mesh and PCB, providing stability to ensure smooth operation of the printing process.

Semi-automatic steel mesh printing machine has a wide range of application scenarios, mainly suitable for small and medium-sized batch production, research and development and prototyping, maintenance and rework and education and training fields. In small and medium-sized batch production, semi-automatic steel mesh printing machine can meet the production needs of small and medium-sized enterprises or workshops, especially suitable for multi-variety, small-batch production mode. In the research and development and prototyping phase, it can help engineers quickly prototype or small batch trial production, accelerate product development process. In repair and rework scenarios, semi-automatic steel mesh presses can be used to repair or replace solder paste on PCBS, improving repair efficiency and quality. In addition, in the field of electronic engineering education and training, it is also widely used in teaching and training to help students master the solder paste printing process in surface mount technology (SMT). Due to its flexibility, cost-effectiveness and ease of operation, semi-automatic steel mesh presses have become one of the indispensable equipment in the electronics manufacturing industry.
