The use of adaptive laser micromilling technology for the fast prototyping ceramic package of electronic components in a miniature surface mount form factor (SMD) is describing. Current experimental results and practical evaluation of one show that using the developed software and hardware is possible successfully producing SMD packages starting from the SOT-723 form-factor in the direction of larger overall dimensions to SOT-475 form-factor. Also discussed are the limiting physical factors arising in the course of the application of laser micromilling technology, which affect the production speed and quality of the resulting product from monolithic ceramics.

The technological approach for the low-scale production of field-effect gas sensors as electronic components for use in non-lab ambient environments is described. In this work, in addition to the mechanical protection of a gas-sensitive structure, an emphasis was also placed on the very topical issue of thermal stabilization around the one temperature point, even if it is several degrees higher than the surrounding one, which will probably also be useful for any type of application for many types of field-effect sensors. Considerable attention was paid to the characterization of the results obtained by various invasive and non-invasive methods for diagnosing the manufactured construction. The technology described in this article occupies an intermediate position between laboratory samples tested in clean rooms with stable ambient atmospheres, and experimental and small-scale production sensors designed for real operating conditions to solve the narrow application of measuring low concentrations of hydrogen.
