Abstract:
A compound switching matrix apparatus for interconnecting a set of devices that each include first and second contacts to first and second sets of terminals on a measurement system, comprising:a first set of probes contacting the first contacts on the set of devices;a second set of probes contacting the second contacts on the set of devices;first set of probe matrix relays mounted on a first circuit board for selectively interconnecting the first set of probes to a first set of inter-matrix conductors;a second set of probe matrix relays mounted on a second circuit board for selectively interconnecting the second set of probes to a second set of inter-matrix conductors, the first and second circuit boards electrically isolating the first set of probe matrix relays and inter-matrix conductors from the second set of probe matrix relays and inter-matrix conductors:a first set of configuration matrix relays selectively interconnecting the first set of terminals on the measurement system to the first set of inter-matrix conductors;a second set of configuration matrix relays selectively interconnecting the second set of terminals on the measurement system to the second set of inter-matrix conductors; anda laser that cooperates with the measurement system to laser trim a device in the set of devices to a predetermined value.
