Abstract:
An apparatus for testing of electronic devices, the apparatus comprising:a plurality of probe assemblies each including a current carrying portion for electrical testing of the device, a support including an opening with the probe assembly mounted on the support to allow the current carrying portion to be positioned relative to the opening for testing of the device; a carrier having a surface on which the electronic device is disposed to allow the probe assembly portion to test the device; a platform having both the probe support and the carrier mounted thereto for shifting the probe assembly and carrier together while maintaining relative positions between the probe assembly portion and the device the same during shifting of the platform; carrier portions of each of the probe assemblies that are relatively movable with respect to each other for shifting the respective current carrying portions in a plurality of different directions to allow one of the current carrying portions to be shifted independent of another one of the current carrying portions, as well as independent of the shifting of the carrier and simultaneous therewith; and a microscope for viewing the device through the probe support opening with the shifting of the probe assembly and the carrier via the platform allowing the microscope to remain stationary while obtaining images over a large area on the device.
