Research of Material Properties 'Reliability Applied to Numerical Analysis

The reliance of the material properties on the numerical analysis has been studied, focusing the encapsulant of POP (Package on Package). The result of the numerical analysis with the material properties, that the material supplier had announced, did not support the result of the actual hardware testing. Through the research process, I had focused the material properties, and then, the material properties were measured actually with the hardware test piece of parts constructing this product. As the result, the order difference between the material supplier announced data and the measured data was observed. It was recognized strongly that the reliance of the material properties is extremely important, and became possible to study the optimized parameter of the encapsulant with the numerical model in which the measured data was applied.
