    Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board which can surely prevent a poor connection between a terminal pad and a terminal of an electronic component. SOLUTION: In the printed circuit board 17, specific regions 42a-42d are located on the rear side of an electronic component mounting region for bearing the electronic component. In the specific regions 42a-42d, a conductive film 39 is formed according to the ratio of the surface area of the board and the area of the conductive material which is defined by the electronic component mounting region. The ratio of the surface area of the board 28 and the area of the conductive material 39 is adapted to each electronic component by the electronic component mounting region and the specific regions 42a-42d. Thus, the warping of the printed circuit board 17 can be suppressed during heating in the reflow process. COPYRIGHT: (C)2008,JPO&INPIT
