Abstract: In a capacitive-probe assembly used in an automatic circuit tester (10) to sense varying electric fields that result adjacent to integrated-circuit packages (32) during tests of circuit boards (16), a spacer comprising resilient cellular material has a double-sided printed-board attached to it that provides the probe plate (52) to which the device signals are capacitively coupled. The spacer (44) is in turn mounted on a chip-probe mounting surface (30) provided by the tester's fixture (14). The result is a robust fixture assembly that is easy to manufacture.
