1. An apparatus, comprising:
a first substrate having a first contact at a first end of the first substrate, a second contact at a second end of the first substrate, and a first electrically conductive path on the first substrate between the first contact and the second contact;
a second substrate having a first contact at a first end of the second substrate, a second contact at a second end of the second substrate, and a second electrically conductive path on the second substrate between the first contact and the second contact;
at least two connectors located in a same plane, at least one connector positioned adjacent the first ends of the first and second substrates, and at least one other connector positioned adjacent the second ends of the first and second substrates; and
a first movable stage connected to at least one of the first substrate and the second substrate, the first movable stage operable to move at least one of the first substrate or the second substrate to contact the at least two connectors to connect the at least two connectors to the first electrically conductive path or the second electrically conductive path.
