| Abstract: | The characteristics of A1-PCB substrate are tested and contrasted between different manufacturer＇s products. And the CTE mismatching of components and substrate is analyzed. The solutions are presented for decreasing the stress of soldering by optimizing the pad pattern and changing terminal structure. The reliability of different component mounting methods is validated by environmental stress test. |
