The online solder paste printer is a core piece of equipment in SMT (surface mount technology) production lines, used to precisely print solder paste onto PCB pads, providing the foundation for subsequent component mounting. Its core feature is its seamless integration with upstream and downstream equipment (such as pick-and-place machines and reflow ovens) through an automated transfer system, enabling efficient continuous production. Modular design
Stencil system: Made of stainless steel or nickel alloy, with aperture designs customised according to pad dimensions, typically 0.1–0.15 mm thick. Squeegee unit: Made of metal or polyurethane, with an angle of 45°–60°, pressure range of 3–15 N/cm², and speed of 20–80 mm/s, ensuring uniform solder paste filling. Conveyor Track: Automatic board loading/unloading design, compatible with direct integration with pick-and-place machines, minimising manual intervention.
