  • Patent number: 6822436
    Abstract: In order to form a modular interface between a DUT board, which is housing devices under tests (DUT), to cables connected to a test head, a board spacer is provided that has an array of connectors. Each cable is connected to a respective connector, and the DUT board contains a corresponding array of connection points which are less than or equal to the number of connectors in the arrays on the board spacer. In this way, a common board spacer can be used to connect the cables to DUT boards housing different types of DUTs since the location of the connection points on the board spacer is known and kept constant. This interface allows a high speed and high fidelity connection between the test head and the devices on the DUTs for frequencies in excess of 50 MHz.

  • Publication number: 20020089322
    Abstract: A high density connector that connects devices under test and a test head that includes coaxial cable connectors on a first end, and connection points located on a male connector portion at a second end, with a waveguide member connecting respective cable connectors and connection points to create a communication pathway having an isolated ground and a 1:1 signal-to-ground ratio. The connector is a PCB, with the waveguides being in a ground-signal-ground configuration with a signal distance between adjacent waveguides being 0.2 inches or less. The coaxial cable connections are modular, allowing cables from the devices under test to be plugged without soldering. This non-solder connection also allows the cables to be unplugged and replugged as necessary. The male connector portion is connected to a female low insertion force connector on the test head in order to complete the connection between the devices under test and the test head.
