The ULTRA³ model uses the latest measurement technology of the 3D LIST camera. The shape of the smallest solder paste depots plays a major role for the printed volume and ultimately for the shape of the solder joint. Is the paste deposit the same height over the entire surface or does it slope towards the edges? This question is answered by the ULTRA³, which combines a stencil printer and 3D SPI at the same time.
Substrate handling and parallel process
Clamping substrate between hold-down bar and transport belt
Secure fixing of thin substrates without warping
Minimal bounce and overlap of the substrate in the edge area
Stencil bottom cleaning
Parameter setting for wet, dry and vacuum cleaning
With controlled paper feed for reproducible cleaning cycles and adapted material consumption
Intelligent stencil cleaner
Printhead and squeegee
Closed loop control for reproducible printing results
Optional weight compensation of squeegee and printhead enable low squeegee pressures
Advantages VERSAPRINT 2 ULTRA³ stencil printer compared to 3D-SPI stand-alone
3D-SPI for inspection of complex boards directly after printing process
Detect defects through stencil inspection before they occur
Zero point measurement of unprinted PCB any time before printing
Integrated closed-loop function for print offset
End-to-end software platform for printing and inspection
Maintenance and servicing for one machine, one contact for both processes
Less space required in production line
