eldeco is a small company with 4 employees that was founded
in 1990. The main business fields are the development and production of
electronic temperature controllers for different applications in household,
industry and medical equipment.
Before the Application Experiment, the company had experiences in the
design of electronic systems using discrete components and standard ICs
in through hole and SMD technolo-gies. Furthermore, additional know-how
in programming and application of microcontroller for the data processing
parts of the temperature controller units was available.
The object of the Experiment is a temperature control circuit used in
industrial and domestic appliances such as hair dryers and solder guns.
Up to now, thousands of controller units have been developed and manufactured
by eldeco. The high manufacturing costs, the restricted functionality
and the size of the unit prevented a further improvement of eldeco's competitive
Market studies have shown, that the introduction of mixed signal ASIC
technology can open new market segments for eldeco because of miniaturisation,
higher reliability and a lower price. In detail, the manufacturing costs
of the controller unit can be reduced in the range of 30%. One reason
is, that the adaptation of the controller to the resistance of the heater
working as the sensor element simultaneously was done manually for the
old product. Implementing the ASIC, this step of the manufacturing process
can be replaced by an automatic solution.
Because of the reduced size, the new product will open new OEM markets
for eldeco. For instance, the new temperature controller will be used
in hair dryers and industrial hot air pistols.
The higher reliability and the possible lower price open a wide range
of additional applications. eldeco has presented the ASIC based product
concept to 15 new customers. The results are very promising and open good
chances to double the turnover of the company. Furthermore, the ASIC will
be the basis for additional development projects.
Within the Application Experiment, the specialists of eldeco got know-how
in microelectronics technologies. They learned to understand the benefits
of ASIC application, to plan and to manage mixed signal ASIC projects,
to avoid possible pitfalls (contracts with partners, patent rights), to
calculate project costs and to co-operate with design-houses and silicon
vendors, and to specify mixed signal ASICs and its system interfaces.
Furthermore, they got an overview about design methodologies and test
The project had a duration of 20 months, an extension of two months because
of foundry problems included. The total project costs within FUSE were
155 kECU. eldeco expects a payback period of less than 4 years, and an
ROI of 2 ½ times assuming an 8 year product life.
