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.

Comparison of fatigue fracture criteria for torsion
Roh, Marek ; Slámečka, Karel (referee) ; Horníková, Jana (advisor)
The main goal of this bachelor thesis is to determine which criteria better suits the life prediction of the test sample loaded in the pulsating torsion. In the first part of this thesis fatigue failure will be examined, then fluctuating stresses will be characterized along with shear stress. Characteristics of the materials used will be specified in the second part. Lastly, the most appropriate criteria will be determined.

Generating coordinate data for PCB X-ray machine
Popela, Vojtěch ; Kubánek, David (referee) ; Hanák, Pavel (advisor)
The aim of this thesis was to pick up with the structure of soldering pads positional data of PCB Phoenix X-ray Micromex 180 and then to create programs for export of input data for this device. Theoretical part of this thesis is dedicated to the description of X-ray equipment and also, to the issues of conversion of positional data, folowed by PCB manufacturing formats description. The first part of the thesis deals with the process of creating the User Language Program (ULP) for PCB design software Cadsoft Eagle, in second part a program was made program for exporting data from ODB++ format.

Exposure equipment for PCBs
Fiala, Matouš ; Čech, Ondřej (referee) ; Vyroubal, Petr (advisor)
The Master's thesis deals with the fabrication of printed circuit board exposure devices, including establishing a theoretical basis for understanding the PCB production process, using lithography over a liquid crystal panel to create a motif. The thesis includes the creation of a CAD model of the device, including a UV source and then thermal simulation of the cooling of the device. The fabrication of the device also involved the creation of a custom motherboard that integrates all of the electronic components. The main result of this work is an assembled functional device with a unique LCD layer arrangement that allows reliable exposure of dual-layer PCBs, which is supported by testing. The most comprehensive part of this thesis deals with the development of a complete software platform, consisting of an application running on the microcomputer of the exposure device and a multi-platform application through which the device is wirelessly controlled.

Výroba desek plošných spojů pomocí CNC zařízení s využitím Open Source nástrojů
HOUŠŤ, Milan
This bachelor thesis aims to describe the production process of prototype and small series printed circuit boards on a computer numerically controlled (CNC) milling machine, and to document a practical reproducible working procedure using CAD-to-CAM files and open source tools to create a CNC control file. In the analysis section the results of the proposed procedures will be presented using a specific printed circuit board as example.
