Printing
Solder paste is printed with a patterned screen. The screens have etched openings to match the patterns on the PCB’s.
Due to fine- patterned circuits, the accuracy of alignment is crucial.
For high productivity, not only the high throughput, but also the minimisationreduction of change- over time is a key issue.
To reduce the downtime, all the control and& sensing has to be stable, regardless of the variety of PCBs.
