Abstract(in English) | Plastic encapsulated semiconductor package may crack if an internal delamination is induced during the reflow soldering process. Evaluation of structural Integrity in the packages is becoming increasingly important. Firstly, three-dimensional stress analyses were carried out to obtain stress distributions in the package during the soldering process. Secondly, the adhesion integrity between chip backside and resin was predicted by comparing the analytical results for the package and the stress distribution calculated from adhesion strength test results. Next, integrity of resin edge structure was estimated using criterion calculated from fracture toughness and bending strength for resin. Finally, the new evalution method was confirmed to be effective by comparison with package reliability tests. |
