Paste Printing

No production process in the SMT line is influenced by the interaction of man, machine, material and method as much as the printing process. As a result, 60 to 80 percent of errors in a production line are still attributed to paste printing.

In addition to a stable, robust system, efficient closed-loop process control is also an advantage.

Requirements for a printing system:

  • Flexible frame mounting
  • Bottom side cleaning – wet – vacuum – dry
  • Programmable doctor blade pressure and speed
  • Short cycle times
  • Active cooling should be possible
  • 2D paste inspection
  • Closed-loop process control
  • Robust design
  • Good accessibility
  • High precision for 0.3 mm QFP, 0.2 mm BGA
  • Closed loop control possible with various SPI manufacturers
  • Patented side clamping for printing without jumping off
  • Includes 2D solder paste inspection
