Closed-loop interface optimises print process
After extensive testing, Panasonic have implemented Viscom's closed-loop interface into it's printers and placement machines. The interface, developed by the two companies, provides a closed control loop between solder paste inspection (SPI) and printer. This allows the print process to be inspected and immediately optimised. To automatically correct the printing process, data is sent from the SPI directly to the printer.
With this information, the placement process can also be optimised. Following the SPI results, the placement machine can adapt the placement position to the real paste print. This can be advantageous for small components and reduce the risk of tombstones. The SPI results also allow the cleaning cycle to be optimised and adapted to meet specific needs.
Through integration of the Panasonic interface, Viscom customers can now use the complete Quality Uplink package for Panasonic equipment. With this, all inspection data and images of the inspection stages, including 3D SPI, AOI, AXI or MXI, can be saved and linked. This information can then be used for a multitude of applications for optimisation of the individual inspection and manufacturing steps, conserving resources and lowering energy costs.
"We are happy about the excellent cooperation with Panasonic,” says Detlef Beer, responsible for product development of AOI assembly inspection at Viscom. “Also, now we can offer our customers the Closed-Loop Interface to Panasonic printers and placement machines. We make all paste measurement values available to the placement machine referenced to component type and to pad."
