Surface Finishes of Copper in PCBś Production
Bedlek, Marek ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
This work examines and compares properties of different types of surface finishes, their qualities and shortcomings and perspective for future use. Emphasis is placed on new product in the field of OSP, Glicoat F2 from SHIKOKU CHEMICALS CORPORATION and immersion tin. It evaluates their influence on solderability and its changes after several reflow cycles and isothermal aging.

Electrochemical preparation of fluorescence sensor with highly ordered nanostructured surface
Bedlek, Marek ; Kolíbal, Miroslav (referee) ; Drbohlavová, Jana (advisor)
This work deals with fabrication and examination of optical properties of self-ordered TiO2 and Au quantum dots array and its potential usage in medicine as optical sensor for biomolecules detection. Controlled anodization of Ti through Al2O3 template was chosen as a fabrication method for TiO2 QDs, in case of Au galvanic deposition through Al2O3 template onto beforehand prepared TiO2 QDs or substrate with dimple structure. The influence of anodization and deposition conditions on the final structure of QDs and their emission spectrum is also examined.
