SMT Screen Printer, Solder Paste Screening Printing Machine, SMT Stencil Printer
1. The fully automatic solder paste screen printer is outfitted with two stepper motors, suspended printing head and two squeegees whose pressure can be adjusted independently to avoid in-conformities caused by fatigue deformation. Such a design effectively controls the stroke, improves printing quality and prevents solder paste leakage.
2. A longer service life has been assured by the standard stainless steel squeegee.
3. An accurate aligning system ensures no error.
4. The solder paste screen printer is also designed with dry-type, water-type or vacuum cleaning system, suitable for different stencils.
5. The PCB holding device is equipped with magnetic pin and vacuum disc, allowing for no deformation and flatness of PCB.
