Abstract
A printed circuit board unit comprising a printed circuit board and a correction member. The correction member contacts the printed circuit board at a pair of contact points and support points arranged between the contact points. The support points are defined at a position withdrawing from a plane including the contact points. Screws serve to urge the printed circuit board against the correction member. The correction member is adapted to generate an intentional warp or bend. Such warp serves to correct or modify the curvature of the front surface of the printed circuit board. The front surface of the printed circuit board can be maintained flat.
