Abstract
SDT International S.A./N.V. develops, manufactures and commercialises measurement equipment for preventive maintenance and quality control, for all industrial sectors. Since close to 20 years, SDT specialises in ultrasonic signal treatment. All products in its portfolio are in-house developments.

The existing product is an ultrasound-based control and measurement equipment, to control the operation of automatic screw tightening machines. It is using advanced technology, multi-layer boards with high-speed circuits, advance RISC and DSP applications, surface-mount technology.

The newly adopted mixed signal ASIC technology is replacing 620 ECU worth of advanced discrete, mainly analog components, by a 64 mm2 0.7Ám CMOS circuit, costing 37 ECU in volume series of 200-450 units per year.

The project started 1st May 1996, and lasted for 32 months. The project has been on hold for 14 months, because of reasons not related to the development. The total development cost was 250 kECU, 113.8 kECU of that for the development of the ASIC, which is the part funded by FUSE.

The cost reduction will allow targeting new market niches. The forecasted return on investment will be 632 kECU over a period of 4 years, an internal rate of return of 66% per year, over the same period, and a return-on-investment of 225% over 4 years.

Lessons learned are that the approach to implement analog systems using integrated circuit technology is completely different from the approach using discrete components. The production of test-structures using multi-project wafer services can be done at low cost. Significant results can come out of these tests, allowing significant saving in cost and lead-time to working prototypes, by avoiding iterations at the end of the development.
