Analysis of Aplication Flux and Solder Paste on PCB for BGA components
Toufar, Michal ; Řihák, Pavel (referee) ; Vala, Radek (advisor)
This thesis deals with rework of BGA components. There are described defects and errors in a solder joints. The current trend is focused on thin packages with fine pitch. It is assembled with smaller and smaller solder balls. It is described effect of different application of flux and solders paste for rework. The main part is focused on dipping and dispensing. These methods are suitable for repair process.

Metody nanášení hydrogelů na povrch ovoce a zeleniny
Hrabová, Martina
The aim of this thesis was to develop a methodology for applying biopolymer mixtures directly onto the surface of selected fresh foods, fruits and vegetables, and to evaluate the prospects of biopolymer mixtures based on egg white. The theoretical part of this thesis outlines the issue of the packaging industry and the causes of food spoilage. Furthermore, methods for the application of biopolymeric coatings and films on a laboratory scale are described and natural polymers are summarized. In the experimental part of the thesis, the most suitable coating mixture was selected regarding the evaluation of strawberry and cucumber samples’ coating made of different biopolymeric mixtures. For this coating mixture, the samples of fruit and vegetable were subjected to analysis by near infrared spectroscopy.
