Testing station for PCB device check
Stejskal, David ; Baštán, Ondřej (referee) ; Arm, Jakub (advisor)
The testing process is not an indispensable part only of production, it serves to verify the properties with regard to the specific requirements for the final product. The main purpose of testing is, without a doubt, to reduce the service costs in the future. It is certainly no surprise that there is an effort to automate this process as efficiently as possible, especially for larger series of products. The purpose of this master's thesis is to design a concept and subsequently an electrical, hardware and software solution of a testing device for the output inspection of manufactured printed circuit boards (PCB). The specificity of the work consists in the creation of a universal testing PCB that can program and debug AVR microprocessors and chips from the company Espressif, and at the same time it is able to perform automatic tests through the so-called customizable PCB. The customizable board is a designation for a test stand that must always be designed specifically for a particular product (tested PCB). To communicate with the peripherals used on this board, the test PCB exclusively uses the I2C bus, the great advantage of which is the need to use only one pair of wires. A service desktop application was created to control and visualize the test process.
