摘要： An electronic tester with digital, and analog, and memory test circuitry on a single platform. A test head is coupled to a device under test. The device under test can be a system-on-a-chip integrated circuit, a mixed signal integrated circuit, a digital integrated circuit, or an analog integrated circuit. Digital test circuitry applies digital test signals to the device under test coupled to the test head and receives digital outputs from the device under test in response to the digital test signals. Analog test circuitry applies analog test signals to the device under test coupled to the test head and receives analog outputs from the device under test in response to the analog test signals. Memory test circuitry applies memory test patterns to the device under test coupled to the test head and receives memory outputs from the device under test in response to the memory test patterns. A tester computer supervises the application of digital, analog, and memory test signals from the digital, analog, and memory test circuitry to the device under test such that signals applied to the device under test can be solely digital test signals, solely analog test signals, solely memory test signals, or mixed digital, analog, and memory test signals. The test head, the digital test circuitry, the analog test circuitry, the memory test circuitry, and the computer are operable as a single platform.

摘要： A dual-sided test head for an integrated circuit test system. Each side of the test head has a floating contact surface which provides an electrical contact interface between one side of the test head and a respective load board. Each load board is part of a respective integrated circuit handling system. As the test head has two sides and a load board is contacted at each side, the floating contact surfaces facilitate docking of the test head to the respective load boards. The contactors are floating so as to have freedom of motion to rotate, tilt, offset laterally or offset vertically, relative to the test head.
