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.

The conductive layers in LTCC
Poledník, Tomáš ; Psota, Boleslav (referee) ; Kosina, Petr (advisor)
The bachelor thesis was focused on a determination of the limits of screen printing and on estabilishing a power loading of layers on LTCC. It describes the print of the conductive themes via the screen-printing method on the substrata. The thesis contains the description of a measuring on the conductive layers, and a processing its results. It was also performed the printing of layers on a corundum ceramics in order to compare the results. From the measured values were formed the graphs, which represent the possibility of the power loading of layers depending on the temperature and on the width of the thick-layer guide.
Optimalization of power supply for LED light sources
Koždoň, Jakub ; Kosina, Petr (referee) ; Boušek, Jaroslav (advisor)
This work focuses on description of function, analysis of degradation process, measuring lifetime and design thermal and electrical driving circuit for LED. Lifetime power LED basically depends on their working temperature. So some methods for measuring and determine LED lifespan and impacts which affects their lifetime are going to be described. Driving circuits are one of keys of element lamps. Their characteristics can affect lifetime of all lamp. So some properties and impacts of circuits for driving LED's and their functions which are necessary need to know in design will be described . I'll also catalogue some circuits which are suitable for that and show particular design power supply for LEDs and it's realization.
Planar LED Display Application
Houserek, Jiří ; Kosina, Petr (referee) ; Šandera, Josef (advisor)
This coursework deals theoretical with design and construction of the electronic clocks controlled by DCF77 signal, which is broadcasted from Germany. This device will be used as alarm and is able to show date. There is used display, which consists of 8x32 LED matrix in a modular, which is connected to main board over the edge. This device is controlled by microcontoller PIC16F887A. There are described displays, microcontrollers and DCF time signal.
SPC for LCD monitors production
Hořký, Petr ; Kosina, Petr (referee) ; Novotný, Radovan (advisor)
Statistical Process Control (SPC) is currently the most widely used analytic methods to monitor, control and improve the quality of manufactured product. The application of SPC is demonstrated by practical example from the LCD monitor production environment with a focus on LCD backlight sources analysis. The objective is to become familiar with the applied methods and SPC software support.
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.
