Process quality control

with the modus CC AOI (CCI)

Modus pioneered in manufacturing scanner- and camera-based conformal coating inspection systems. Since 2007 we have successfully installed a number of CC AOI systems all over the world.

Scanner technology

for conformal coating inspection

Modus scanner systems power a cluster of UV-LEDs in order to detect the UV trace in conformal coating. The fluorescent material enables us to not only detect the mere presence of coating, but also stray objects with an accuracy of 42μm. With an (optional) sensor we are even able to measure the thickness of the coating, thus ensuring the quality of the coating process according to IPC-A-610.

AOI Process

Process optimization

with modus THT AOI

Typical modern production processes consist of a number of single steps. For example, electronic and mechanical parts such as screws and locking devices are assembled to a module.
To receive a flawless end product and reduce the cost of quality control and ongoing maintenance, inspection is required to ensure escapes are not transferred to the next process step. AOI (Automatic Optical Inspection) allows economical control of various processes. Automatic and manual manufacturing steps are verified using various criteria. There is a demand for a flexible solutions. Modus AOI offers a complete inspection solution for a variety of requirements while providing easy to use tools for test plan creation.

AOI inline-scanner

for the selective and solder wave process

In the production process, integrated inspection required the development of new optical inspection systems for specific demands. The bottom systems (modusAOI MLD1200-IUA) inspect components and solder joints directly after the selective/wave soldering process. The reliable detection of open solder joints, solder bridges, missing pins as well as meniscus inspection on the bottom side, significantly reduce the failure rate.
modusAOI offers an additional advantage: the expensive turn tables are no longer necessary. Dual systems (modusAOI MLD1200-IDA) allow the simultaneous testing of the assembly from both sides.

The test data is displayed at the repair station. Your repair is well assisted and documented. This ensures quality and a stable process. In times of traceability and closed-loop, the inspection of every production process is gaining more and more significance. The barcode or data matrix code can be captured by the AOI from both sides.
The modusAOI dual systems – like all modusAOI variants - support traceability. They are available
as inline or standalone versions. They have been developed based on customer requests. ModusAOI saves time, space and money. The typical amortization is between eight and twelve months.
