Ultra Low Cost Test Platform

The topic of this work was to design and implement an inexpensive test system for production testing of printed circuit boards. The system is designed to be manufactured simply and easily using commercially off-the-shelf products. Ready-made expansion boards and component are utilized to make the manufacturing of the system easy, fast and as cheap as possible. The work focused on the development of electronic hardware for the system. Software development and mechanical design were only partially within the scope of this work. If the system enters production phase, an external provider may be used to design the final version of the software. However, to verify the functionality, a test software was developed, intended to be as close to the final version as possible. The work resulted in a test system based on Raspberry Pi that can be used to test simple circuit boards that can have a few dozen test points. The system was manufactured with a purpose-built Python program at the Lohja plant of Enics Finland
