Abstrakt v primárnom jazyku

This bachelor's thesis focuses on the etching process of printed circuit boards. The design of the device for etching printed circuit boards is the main topic of this thesis. The device includes a heating unit regulated via thermostat, a piezoelectric ultrasonic transducer and an ultrasonic generator with an electric current amplifier, which are all concurrently used to accelerate the etching reaction. The device is designed so that its size and functionality are suitable for a laboratory environment. In this thesis we focus on the production of printed circuit boards and the various methods of etching off the copper layer from the surface of the boards. We primarily focus on etching using an acidic liquid etchant, ferric chloride, but we also consider various other suitable methods of copper etching. The proposed device accelerates the chemical etching process by thermoregulating the reaction and agitating the etching solution. The work also includes proposals for schematic solutions of some necessary circuits for the proposed device. The functionality of the designed circuits is based on simulations in the NI Multisim simulation program.
