Evaluation of the Submodeling Technique for Analyzing Electronic Components

Abstract

The use of submodeling in a finite element model for structure response is investigated for a simple structure representative of an electronic circuit board subjected to projectile launch conditions. The basic technique and rationale for submodeling are discussed. The consequences of sampling rate when one is using the global model's response as input for the local model's response are also highlighted. Additionally. the effect of submodeling in introducing artificial high frequency response is shown. Finally. it is shown that with proper selection of model parameters. submodeling can provide accurate stress results of electronic components in conditions simlar to gun launch.
