Claim Text:
1. An apparatus comprising: a substrate; a first connection pad on a first side of the substrate having a connector pitch to couple to a space transformer of automated test equipment, the space transformer transforming a connector pitch from a connector pitch of a printed circuit board to the connector pitch of the first connection pad of the substrate; a second connection pad on a second opposite side of the substrate to couple directly through probes to a device under test; a first via within the substrate to carry power as current from the first connection pad; a second plurality of vias within the substrate that are smaller than the first via to receive power from the first via and carry the received power to the second connection pad; and an overcurrent limit circuit between the first via and the second plurality of vias to electrically connect the first via to the second plurality of vias and to electrically disconnect the first via from the second plurality of vias when the current between the first and second plurality of vias is over a predetermined amount.
