Product Details
SMT PCB Solder Paste Screen Printer for SMT is needed to screen print solder paste onto the printed circuit board (PCB) before placement of surface mount components (SMD) for Reflow Soldering.
Solder Paste Screen Printer for SMT have been widely used by Top electronic companies in and the PCB industry for screen solder mask.


1. Automatic PCB solder paste screen printer with pecial manual lifting platform is simple and reliable structure, low cost, easy to manually adjust, you can quickly achieve different thickness of the PCB board PIN pin height adjustment.
2. Image and optical system:Using uniform ring light and high brightness coaxial light,with promise brightness adjustment function,then all type of Mark points can be well recognized (including the rugged Mark points),applicable for tin plating, coppering,gold plating,FPC and other types of PCB with different colors.
3. Cleaning system:dry cleaning,wet cleaning,vacuum,which can be combined to use cleaning system, a new type of wipes to ensure full contact with the steel mesh, increase the type of vacuum suction to ensure the elimination of residual pores in the mesh, the real effective automatic cleaning function: dry and wet three cleaning mode, the software is free Set the cleaning mode and the length of the cleaning paper
4. Scraper system: Slide type scraper system to improve operational stability and extend service life
5. Friendly Chinese/English operation interface and Steady steel net fixing structure
6. High adaptability steel mesh frame mounting system.
7. 2D paste printing quality test and analysis
How does the PCB solder paste printer machine work?
Semi-automatic pcb solder paste printer machine: simple operation, fast printing speed, simple structure, the disadvantage is less control of printing process parameters, printing centering accuracy is not high, solder paste release is poor, generally applicable to 0603 (inch) above components, pins PCB printing process with a pitch greater than 1.27mm.
Fully automatic PCB solder paste printing machine: high printing centering accuracy, good solder paste release effect, and stable printing process, suitable for printing with fine pitch components. The disadvantage is high maintenance cost and high requirements for the operator's knowledge level.
Solder paste and patch glue are all thixotropic and sticky. When the smt printer scraper moves forward at a certain speed and angle, it exerts a certain pressure on the solder paste, pushing the solder paste to roll before the scraper, and generating the pressure required to inject the solder paste into the mesh or the drain hole;The sticky friction of the solder paste causes the solder paste to produce a shear at the intersection of the smc printing machine scraper and the mesh plate. The shear force reduces the viscosity of the solder paste and facilitates smooth injection of the solder paste into the template opening or the drain hole. Scraper speed, squeegee pressure, angle between the squeegee and the stencil, and the viscosity of the solder paste all have certain restrictions, so only by properly controlling these parameters can the solder paste quality be guaranteed.
