| Zusammenfassung: | A test access point structure for accessing test points of a printed circuit board and method of fabrication thereof is presented. In an x-, y-, z-coordinate system where traces are printed along an x-y plane, the z-dimension is used to implement test access point structures. Each test access point structure is conductively connected to a trace at a test access point directly on top of the trace and along the z axis of the x-, y-, z-coordinate system above an exposed surface of the printed circuit board to be accessible for electrical probing by an external device. |
