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.

Abstract: Disclosed is a flame-retardant styrene resin composition. The composition comprises 100 parts by weight of a styrene resin, 0.5 to 10 parts by weight of a brominated flame-retarder which has a bromine content of 60% by weight or higher, and 0.005 to 0.5 part by weight of urea, thiourea or an N-substituted derivative thereof. By using an urea compound concomitantly, the amount of the brominated flame-retarder required for achieving a desired flame retardancy level can be reduced.
