- Abstract
Miniaturization increases more complexity in Integrated Circuits (IC) as well as circuit boards. Several electronic components are assembled on a Printed Circuit Board (PCB). The board is a composite material of a fiber reinforced thermosetting polymer based matrix. Within and on the board, conducting traces and vertical interconnect access (via) carry out electrical signals. So-called Joule’s heat causes a cyclic occurrence of thermal stresses on vias and traces leading to plastic deformation and fatigue related damage. Multiphysics simulations make a study of this coupled and nonlinear system possible. We demonstrate an attempt to compute an electro-thermo-mechanical system and a damage problem by using finite element method in space and finite difference method in time.
