The lamination of Low Temperature Co-fired Ceramic
Hudeček, Ondřej ; Klíma, Martin (referee) ; Kosina, Petr (advisor)
Master’s thesis deals with the optimalization of low-temperature cofired ceramic lamination process that affects the final quality of 3D structures (eg., channels, cavities, membranes, etc.). The paper evaluates the influence of lamination parameters (pressure, temperature, time) on the formation of defects in the structure, which were detected by appropriate methods. The last parts describes designed and simulation cooling water system using LTCC technology.

SMS gateway with respective software
Bednář, Petr ; Kosina, Petr (referee) ; Jan Šeda, OSA, o.s., Praha (advisor)
This work deals with the problem of creating a text communication between computer and mobile phone users via short message service. The basic focus of work is a grouping of all relevant information leading to the security of communication as the easiest way. One section is aimed at creating the enabling devices to send and receive short text messages and the second describes the software solution aimed at handling equipment and to ensure communication with the third-party software solutions using .NET platform from Microsoft.

Capacitance measurement of high-voltage PN junctions
Derishev, Anton ; Kosina, Petr (referee) ; Boušek, Jaroslav (advisor)
The work deals with the capacitance measurement of high-voltage PN junctions. The work is divided into theoretical and practical parts. The theoretical part presents insight into the fundamental properties of PN junctions and methods for measuring of the capacitance of PN junctions, primarily by C-V measurement. In the practical part, several kinds of measuring circuits are introduced and a suitable method of measurement is found. The calculations of basic parameters - the width of the base and resistivity are presented and discussed. The results were compared with the values obtained by calculation from the technological parameters of the junction.

The via interconnection in LTCC
Sedliak, Erik ; Klíma, Martin (referee) ; Kosina, Petr (advisor)
This thesis deals with manufacturing process of LTCC 3D structures. Emphasis is placed mainly on the formation of via interconnections. In the second section of thesis, different via interconnections were designed, created and tested. Aim of this thesis was to evalute impact of via properties on vias function.

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.
