A circuit board is guided into the correct position over the testing location of a test fixture by means of at least one guide located outside and near to the circumference of the testing location. The surface of the guide which faces the testing location is sloped outwards and upwards, the guide preferably being conical in shape. In test fixtures provided with tooling guide pins which fit through tooling holes on the circuit board for the purpose of accurate positioning over the test location, the lower part of the guide to approximately the same height as the pins is cylindrical, the upper part of the guide being conical.
