WebMay 2, 2002 · Thermo-setting polymers are widely used as underfill materials to improve the reliability of electronic packages. In the design phase, the influence of underfill applications on reliability is often judged through thermal and mechanical simulations, under assumed operating conditions. Because of lacking insight into the mechanical processes due to … Webconventional thermal curing processes for polymer composites are time and cost intensive. In order to keep the temperature profile in range without degrading the composite parts, very low heat up rates (1-2 °C/min) are used during the curing process, which leads to long curing cycles with high energy consumption. In certain applications
