    Abstract: A printed circuit board which facilitates the removal and replacement of components. The circuit board (1) has unplated holes (8) extending therethrough for receiving connection pins (3) of components (2) mounted on one face of the circuit board (1). The pins (3) protrude from the opposite face of the circuit board (1) and are soldered to conductive pads (9) on this face which are connected by surface conductors (10) to plated through-holes (4) linking conductive tracks (6,7) at different layers of the circuit board (1).
