Photonic Services Testbed
Kubica, Matěj ; Škorpil, Vladislav (referee) ; Horváth, Tomáš (advisor)
Bachelor thesis focuses on the theoretical analysis of optical cables and it‘s fusion splicing and distribution. This thesis deals with basic difference between different types of optical fibers. Importance is put on singlemode fibers and it‘s standardization. Following by analysis of different techniques of uniting optical fibers and distribution of cables inside buildings. In the practical part the realization of individual joints with measured values is described. Next part describes connection of individual fibers into optical bath. This connection is completely documented and certain services are realized on selected fibers

Modification of PCB cleaning process after removing BGA component
Procházka, Adam ; Bžoněk, Tomáš (referee) ; Řezníček, Michal (advisor)
This bachelor thesis deals with the modification of DPS cleaning process after the removal of BGA components. The thesis is divided into five main parts including the introduction and conclusion. The introduction comprises an assignment and aim of the thesis. The first, theoretical, part then deals with different kinds of soldering, individual types of solders and the rework process itself. The second part examines the whole practical part in detail, from the proposal of the test printed circuit board to its mounting, soldering and subsequent testing. Also, it explains the practical tests for connectors. The third part then describes the board testing by thermal cycling. The last part consists of the summary of results, a comparison of individual soldering pastes and conclusion.

Construction and Making of a Shear Tools
Dziuban, Jiří ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis describes the production technology of cutting progressive dies and their modifications, the high-speed press production of instruments connectors for automotive speeds of up to 1350 strokes per minute. Production of these connectors leads to specific problems with the complexity of shape and exact dimensions. This paper describes the problems and faults found in the production of these connectors, some of their causes, and presents design modifications to remove them. All proposed design modifications have been applied in practice and can be widely applied to various tools.

Infrastructure for electromobility
Smutková, Karolína ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This thesis deals with the issue of charging electric vehicles, including a number of sub-questions. It provides an overview of current charging stations, connectors, communication between vehicle and charger during charging and of the resulting price for charging. It also takes into account the need for large amounts of energy mostly from renewable sources, coupled with battery storage facilities. The last point is a comparison of current electric vehicles mainly by battery capacity, price and range. The whole thesis is primarily related to the territory of the Czech Republic.

Adjustments Shearing Procedure Tools
Dziuban, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This thesis explains how to determine and eliminate the causes of quality problems in the production of connectors and small electronic components for the automotive industry. The process of making these components is carried out by use of both high speed and low speed metal stamping presses. There are descriptions of the different designs of editing punches, stamping dies, trimming and molding tools and how unplanned issues can occur during the production process. It addresses all the customer requirements for quality end products, listing the type of material, finishes and technology used for the production of individual components as well as their functionality, durability, and economic impacts. All examples of changes in the design or technology of metal stamping presses are based on many years of practical experience and most of them can be successfully applied in other similar type of instrument production.

Optical fiber polygon for testing of services
Frolka, Jan ; Horváth, Tomáš (referee) ; Dejdar, Petr (advisor)
Bachelor’s thesis describes the types of optical fibers, their structures and properties. The basic parameters of optical fibers and standards for single-mode fibers are defined. The differences between the various connectors and the polishing of the ferrules are also described. The next section describes the multichannel transmission technology and its modifications, as well as the FFTx technology. In the next part, the work deals with measurements on optical fibers, the most common measurement methods are listed. The reader will learn what to do and also what not to do when manipulating with optical elements. The attached diagrams show the test polygon, as well as the measured and calculated values of the attenuation of its parts.
