Configuration

1. Suspended print head with squeegee pressure automatic adjustment by direct-connected motor

  a) Programmable automatic pressure adjustment system ensures accurate pressure control.

  b) Pressures of front and rear squeegees are separately adjusted, to compensate pressure imbalance caused by fatigue deformation of squeegee to prevent from different printing quality in front and rear.

2. Standard stainless steel squeegee, unique design to improve the lifespan of squeegee blade.

3. Vision alignment system.

4. Table X/Y/θ automatic calibration system.

5. PCB clamping and support system:

  a) Magnetic pins

  b) PCB flexible side clamping system to ensure no bending and deformation during PCB clamping

  c) Automatic adjustment lifting platform.

  d) Flexible automatic pin(optional)

6. NC slide way adjustment for conveyor width and speed.

7. Dry-type, wet-type or mixed combination of the two types for stencil cleaning system.

8. System Requirements: IPC (Industrial Personal Computer) with Windows XP System

9. Built-in software diagnosis system.

10. Standard SMEMA port.
