Paper Abstract

In this paper, phase-shifting moire method was employed to investigate the machining effect on the warpage of electronic packagings undergone thermal cycles. Four types of machined slots were tested and compared with the unmachined one. It was found that they all give significant improvement on the warpage. However, the crossed type slot gives the largest reduction of warpage.
