Patent ID: 7609078

Claim:
In an electronic testing machine including at least one test module having a plurality of contacts for testing electronic components, the improvement of a contact alignment tool for aligning the contacts comprising: a body to be positioned relative to the testing machine such that the body can be radially indexed along a path to a contact alignment test position proximate the contacts of the test module; and a plurality of circuits associated with the body, each circuit including at least one output signal connection and at least one open contact station, each open contact station defined by at least one open circuit trace pattern, such that each open contact station will be closed by the contacts when the body is located at the contact test position proximate the contacts and the contacts are properly aligned; wherein the at least one open contact station includes: a first trace pattern positioned on the body relative to the path and including a trace width, a trace gap and a trace height; a second trace pattern positioned on the body relative to the path and including at least one of a trace width, a trace gap and a trace height different from that of the first trace pattern; and a third trace pattern positioned on the body relative to the path and including at least one of a trace width, a trace gap and a trace height different from that of the first trace pattern and at least one of the trace width, the trace gap and the trace height different from that of the second trace pattern.
