Testing a PCB assembly can be very time consuming due to its complexity andcompactness. Tests are desired to be consistent and test coverage should be as highas possible, which is perfect for automated testing software.This thesis intends to develop computer controlled tests of faulty PCB assembliesusing boundary scan, which is meant to quickly locate the error so that an analysisengineer can evaluate it and prevent it from happening in future versions of theproduct. Boundary scan is even able to test the inner circuitry.Testing with boundary scan has been around for quite some time, but in recentyears it has shown to be truly valuable and time saving, due to the increasingcomplexity of PCB assemblies. The conclusions reached in this study are promisingfor future tests and development of PCBs using boundary scan, which has shownto be quite the powerful tool.
