A device comprising a single-sided printed circuit board (PCB) having a non-metallized hole, and a connection area (CA) close to the non-metallized hole on a metallized side of the single-sided printed circuit board. The present invention provides a conducting bridge (CP) from the connection area (CA) and at least partially covering the non-metallized hole, for allowing the connection area (CA) to be contacted, e.g. by a probe (P), from a non-metallized side of the single-sided printed circuit board (PCB) through the non-metallized hole.
