Abstract

According to one embodiment, a printed wiring board structure comprises a printed wiring board having first and second component mounting surfaces at front and back sides thereof, respectively, each for mounting a semiconductor package loading a semiconductor chip loaded on a substrate as a mounting component, a first semiconductor package mounted on the first component mounting surface, and a second semiconductor package mounted on the second component mounting surface, wherein the first and second semiconductor packages have a positional relationship such that the substrates are partially overlapped via the printed wiring board, and the semiconductor chips are not overlapped.

Description

technical field [0001] One embodiment of the present invention relates to a printed wiring board structure in which semiconductor components having semiconductor chips mounted on a substrate are mounted on both sides of the printed wiring board. Background technique [0002] A circuit board, on which large semiconductor components forming a CPU and its peripheral circuits are mounted, is provided as a main component in a casing of an electronic device such as a personal computer. This large semiconductor component has tens of millimeters square. [0003] Such circuit boards for electronic equipment such as personal computers require means for protecting the mounting surfaces of semiconductor components. In particular, it is necessary to protect the mounting surface from bending and deformation of the substrate and from stress applied by external shocks and vibrations. [0004] For example, a method disclosed in Japanese Patent Application Laid-Open No. 2002-271014 has been...
