Claim 0:
1. A sensor interposer comprising:
a planar substrate defining a plurality of castellated through-vias;
a first electrical contact formed on the planar substrate and electrically coupled to a first castellated through-via;
a second electrical contact formed on the planar substrate and electrically coupled to a second castellated through-via, the second castellated through-via electrically isolated from the first castellated through-via, wherein the planar substrate defines a closed perimeter through hole between the first and second electrical contacts;
a first guard trace formed on the planar substrate, the first guard trace electrically coupled between a third and a fourth castellated through-via, the first guard trace isolating the first and second electrical contacts, wherein the third castellated through-via is formed in a perimeter of the planar substrate, and the fourth castellated through-via is formed in a perimeter of the closed perimeter through hole, and;
a second guard trace formed on the planar substrate, the second guard trace electrically coupled between a fifth and a sixth castellated through-via, the second guard trace isolating the first and second electrical contacts, wherein the fifth castellated through-via is formed in the perimeter of the planar substrate, and the sixth castellated through-via is formed in the perimeter of the closed perimeter through hole.
