Design of a fluidizing device for encapsulation
Lizúch, Ján ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
The aim of a bachelor´s thesis is to design and construct a model of fluidized bed for encapsulating a hybrid integrated circuits. A theory about hybrid integrated circuits, their packages, principles of fluidized bed and about organic materials suitable for fluidization is included in a first part of the thesis. Next parts of the thesis discusses a design of a theoretical model and its practical construction part. Thesis also contains a part about fluidization process optimalization for a specific encapsulating material.

Electrical properties of thick-film resistive pastes
Gajdoš, Jiří ; Buršík, Martin (referee) ; Řezníček, Michal (advisor)
This work deals with the technology of thick-film electronic circuits, describes the materials used for the implementation of a thick-film circuit and basic operations for their production. The content is also a proposal resistive pattern, which allows measurement of thick-film resistive inks. The practical part describes the creation of resistive pattern, creating measuring station, measurement of values of resistors, measurement temperature coefficient of resistance TCR and interpretation of evaluation.

Electrical properties of thick film pastes measured in a wide temperature range
Gajdoš, Jiří ; Jankovský, Jaroslav (referee) ; Řezníček, Michal (advisor)
The aim of this master’s thesis is to investigate the electrical properties of various thick-film resistor pastes in a wider temperature range. The thesis mainly focuses on a change in electrical resistance depending on temperatures, which extend to the cryogenic region. To achieve this, there is an overview of the thick-film technology properties, major technological procedures, principles of resistive pastes conductivity, methods of electrical resistance measuring, possible errors in measurement and methods of their minimization. The content of this work is also familiar with the characteristics of a cryogenic station, on this foundation was proposed the measurement procedure and created thick-film circuits for this station. After measurement in the interval 10 K to 350 K, there are subsequently evaluated the data and explains the principles of the conductivity of used pastes.

Cutting module implementation into the Aurel ALS 300 trimming laser software
Štrympl, Martin ; Kosina, Petr (referee) ; Prášek, Jan (advisor)
is project deals with the implementation of a cutting module for trimming laser system Aurel ALS 300. The conversion programme designed to convert the Gerber format into the input laser format was written in C language. Integration of the conversion programme to the control programme of PROTOMAT laser was implemented in Visual Basic 6. The first part of the semester work describes the basic thick-film technology and the use of thick-film resistors trimming. An analysis of allowed input formats PostScript, DWG and Gerber follows. The Gerber format, which is analyzed in detail here, was selected as the input format for conversion. Input data of the laser Aurel ALS 300 are also analyzed. Finally the way of creation of the converstion programme and its use described here too.

Non conventional applications of HIC´s
Grund, Pavel ; Švecová, Olga (referee) ; Szendiuch, Ivan (advisor)
Within the frame of this bachelor’s thesis was carried out given circuit, a capacitive probe. Topology was created during the semester project. The realized hybrid integrated circuit combines two technologies – thick film technology and surface mount technology using SMD components. The bachelor’s thesis is divided on the theoretical part, which contains a description of the theoretical design and production of hybrid integrated circuit, also owns a design capacitive probe in hybrid form with a selection of components and calculates the size of the substrate thick film resistors, and a practical part. The practical part is described in detail the production of our HIC, including verification of functionality.
