Process optimization

with the modus AOI

For an integrated, post-wave inspection solution in the production process, the development of a new optical test system for mounting under a conveyor was developed. The modus AOI MLD1200-IUA checks solder joints and parts directly after wave or selective soldering. The reliable identification of open or incomplete solder joints, solder bridges, missing pins as well as the shape of the solder joint from the wave-solder side reduces test and in-field failures.

The modus AOI offers the additional benefit that expensive flip stations are not required. The gain of space allows simultaneous inspection of the boards from above and from below. At the repair station, the fault data is displayed, the repair is documented and fault condition confirmed. This information, fed back through SPC data can help to improve and optimise process control. Traceability using Barcode or Data-Matrix codes is supported and can be collected by the AOI from above as well as from below with the modus double-sided system. The modus S1-IDA is available as either in-line or offline. They have been developed over the years based on customer needs and requests and they are offered exclusively by modus High-Tech.

Modus AOI systems, saves time, space and therefore money. The typical pay-back period is between eight to twelve months.
