Abstract
An integrated circuit assembly contains a carrier and a semi-conductor integrated circuit chip . A current path on the carrier supplies power to power supply connection of the chip. A magnetic field sensor is provided on the carrier in a vicinity of the current path, for sensing a magnetic field generated by a current through the current path. The assembly contains test-accessible electronic interface to the magnetic field sensor, for testing presence of the current. Preferably the sensors are integrated on the carrier by depositing magneto resistive material and patterning the material so as to provide sensors in the vicinity of current paths. Also preferably, the carrier is an interposer with connecting wiring, which is packaged with one or more integrated circuit chips before mounting the interposer on a printed circuit board
