Quality is an important factor

to stand one’s ground in the future.

For several decades now modus has been operating as a pioneering force in the AOI sector. Our objective is to develop fast scanner systems for industrial use. Modus develops, produces and sells automatic test and inspection systems (AOI) for production control of volume manufacturing.
The increasing miniaturization of electronic devices plus the escalating demands towards quality control and cost effectiveness makes it necessary to have test control units, which are fast, reliable and easy to set up. The modus inspection systems are available both as in-line and off-line. With the ultra-fast scan speed, 100% inspection of visible parts can be introduced into a production line without any loss or reduction to the speed of the line.

Modus has many customers in the automotive, industrial and consumer electronics sectors. Several customers manufacture small batch/high variety, they have a high expectation for production quality and production reliability. It all began 27 years ago with an engineering office with great experience in building test equipment. Modus became a high-tech business company with German design & development and in-house manufacturing of its test systems.

The first prototypes were built in the year 2000 at the headquarters in Willich. Today, there are more than 650 systems in service. This makes modus the European market leader for scanner AOIs.

We believe the main reason for our success is based on a close and trusted relationship with our customers. Our application engineers and software development team always try to guarantee, where possible, a fast reaction time to support and service questions.

Modus and its network of factory trained support partners ensure total customer support within Germany, Europe and at any other global locations.
