Abstract
A contact apparatus can be made by providing a first substrate with electrically conductive terminals and second substrates each of which can have contact structures. Each of the contact structures can have a contact tip. The second substrates can be aligned such that contact tips of the contact structures are aligned substantially in a plane. An optical system can be used to monitor an actual position of the second substrates, and a mechanical system can be used to move the second substrates to aligned positions. The contact structures can be attached to ones of the terminals on the first substrate while the second substrates are in the aligned positions.
