Tiivistelmä
Final testing for a complex product and fixing faults can be challenging. In the case of Optofidelity, the challenge is locating and fixing possible electrical faults during final testing. Optofidelity's products for testing virtual reality and augmented reality glasses are often electrically complex and contain motion control, a lot of I/O signals, and other actuators and sensors.
Modularization of products and division of functions into modules is considered as one option. In the thesis, a module tester is designed, which can be used to test modules before final assembly. The module tester was designed electrically and mechanically according to the given requirements. Requirements included connection interfaces, powers, and data communication.
As a result of the design, a module tester was built, which allows the tester to connect the modules one by one and test the basic electrical functions of the modules. The module tester improves productivity with limited resources because locating the fault is easier and faster. Error correction is also easier when one module does not have many functionalities and it is a significantly simpler entity than the entire final product. However, the module tester created as a result of the Thesis is not capable of automatic testing, but with this, the modules can be safely powered on and the tester can, with the help of an external testing tool, use e.g. the module's motion controllers and motors.
