Abstract: A machine for testing a circuit board of an electrically insulating material includes circuit tracks of an electrically conductive material arranged on one or opposite side surfaces. At least one test surface is provided. The test surface or each of them defines a number of test points electrically insulated relative to one another and arranged in a matrix configuration. For establishing electrically conductive connection between selected test points of the test surface and selected areas, e.g. circuit tracks of the circuit board to be tested, a connector assembly is sandwiched between the one side surface of the circuit board to be tested and the test surface.

Abstract: In a circuit board testing machine for testing a circuit board of an electrically insulating material having circuit tracks of an electrically conductive material arranged on one side surface or on opposite side surfaces, a test surface (84) or two opposite test surfaces (84,84) is or are provided. The test surface or each of the test surfaces defines a number of test points electrically insulated relative to one another and arranged in a matrix configuration. For establishing electrically conductive connection between selected test points of the test surface (84) and selected areas, e.g. circuit tracks of the circuit board (126) to be tested, a connector assembly is sandwiched between the one side surface of the circuit board to be tested and the test surface.
