Abstract
A structure has a printed board carried by a metal chassis. A printed board carrying chassis analyzing system, a printed board carrying chassis analyzing method, a printed board carrying chassis structure, and a printed board carrying chassis analyzing program are provided to achieve a screw-fastened arrangement for predicting unnecessary radiation frequencies and for reducing unnecessary radiation. An equivalent circuit model including a printed board power and ground plane pair, a pair of confronting surfaces of a printed board and a chassis, and screw-fastened grounding posts is generated and analyzed to predict unnecessary radiation frequencies and unnecessary radiation reductions and to select a screw-fastened arrangement for reducing unnecessary radiation.
