Abstract: [cze] [eng]
Bakalárska práca je zameraná na návrh a realizáciu UV LED osvetľovacej jednotky, určenej pre prototypovú výrobu dosiek plošných spojov (DPS) pomocou fotocesty. Návrh je rozdelený do viacerých častí. Zahŕňa výber vhodných UV LED a následnú realizáciu svetelného zdroja, návrh LED budiča zabezpečujúceho napájanie LED konštantným prúdom, ako aj návrh regulácie intenzity jasu na konštantnú hodnotu. V poslednom kroku je vytvorený 3D model konštrukcie zariadenia pomocou CAD softvéru. The bachelor's thesis focuses on the design and implementation of a UV LED exposure unit intended for prototype production of printed circuit boards (PCB) using UV resist photolitography method. The design is divided into several parts. It includes the selection of suitable UV LEDs and the subsequent implementation of the light source, the design of an LED driver to supply the LEDs with a constant current, as well as the design of brightness regulation to maintain a constant light intensity. In the final stage, a 3D model of the device structure is created using CAD software.
