The aim of this work is design and fabrication of micro hotplates. This type of device is often used for gas-sensing applications. The main goal is to produce the structure of the heating membrane using different fabrication process. Only wet etching process is used. Mainly&#x...

This article deals with automatic testing of multimedia units. The aim of the work was to design and implement an automatic test system for a functional parameter measurement of multimedia units. The system was built up with the help of individual measuring devices and the...

This paper deals with the significance of the thermal management for some modern types of electronic packages. The main part is focused on the Quad-Flat No-leads (QFN) package and its mounting ways and means, which depends significantly on their thermal characteristic. Apart from t...

The article presents the results of solderability testing of printed circuit boards. The aim of this paper is to compare different atmospheres for solderability testing with different finishes of printed circuit boards (PCB’s). The article contains method descriptions that were used for ...

The paper presents generator of an infinite impulse response (IIR) digital filter structure for implementation in application specific integration circuits (ASICs). The paper describes the filter architecture with serial calculation. The serial architecture utilizes one shared multiply and accumulate ...

This paper describes design, construction and some recent tests of 3D stacked lead-free soldered structures based on Low Temperature Co-fired Ceramic substrates (LTCC). These structures have a great potential to create compact structure combining multiple different modules in one package. Interna...

The aim of this paper is to present the utilization of modern optimization algorithm called Differential Evolution to automatically fit the measured data from test chip to the appropriate electrostatic discharge (ESD) model without the need of manual model-parameters tuning. In contrast ...

Research in the sphere of random number generators is a dynamically evolving segment. The sequences of nondeterministic numbers with some specific probability distribution are especially required for the need of greater safety. This paper deals with the true random number generator (TRNG)&#x...
