Photoresist exposure via the LCD panel
Fiala, Matouš ; Starý, Jiří (referee) ; Vyroubal, Petr (advisor)
The bachelor thesis deals with the design and development of a device using a liquid crystal display panel to create a motif when exposing a photoresist to ultraviolet radiation. For a functional design, it is essential to understand and comprehend the various components of the device, the physical principles and the control of the exposure process. The first part of the text is a theoretical summary that should introduce the reader to the issues discussed in the following sections. This is followed by an analysis and proposed solutions to specific obstacles related to the design and realization process of the device. The work includes manufacturing of a prototype device, the creation of the device software, and a user interface application through which the device is controlled. The thesis also contains simulations, a CAD model of the prototype, documentation and measured exposure results.

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.

Photoresist exposure via LCD panel
Fiala, Matouš
This paper focuses on development and testing of liquid crystal display exposure device using photoresist for PCB manufacturing. The device is controlled wirelessly via dedicated application on various platforms. Most of the device was 3D printed and motif for exposure can be uploaded to the device in Gerber format, which is used all over the world as manufacturing standard format. The paper also contains CAD model, simulation, exposure results and overview of control application.
