Abstract
A method of generating an electrical component (6) of a hearing aid electrical circuitry on a substrate (1) is suggested, wherein the electrical component is generated by material deposition and the value of a characteristic parameter of the electrical component is measured continuously during the deposition step, whereby the material deposition is terminated as soon as the measured value reaches a predetermined desired value of the monitored characteristic parameter. Thereby, a high precision of the characteristic parameters of electrical components of hearing aid electrical circuitry can be achieved without complicated trimming, tuning or adjustment elements or production steps.
Claims9
Method of generating an electrical component of an electrical circuitry, particularly of a hearing aid, on a substrate (1;
- 15), comprising the steps of
- providing terminal conductors (5, 7;
- 5, 5a;
- 17, 18) allocated to said electrical component;
- generating, by at least one material deposition step, the electrical component (6;
- 16, 22);
- and
- measuring, via said terminal conductors, characteristic parameters of said electrical component and dimensioning the electrical component in accordance with a desired value of a characteristic parameter of the electrical component;
- characterized by the steps of
- measuring continuously, or quasi-continuously in a manner approximating continuous measurement, during the material deposition step or steps, the value of the characteristic parameter of the electrical component (6;
- 16, 22);
- controlling the material deposition in accordance with the measured value of the characteristic parameter;
- whereby the material deposition is terminated as soon as said measured value reaches a predetermined desired value of the respective characteristic parameter.
