Paper Abstract

In this paper, the electron bema moire method and AFM scanning moire method are proposed to measure the thermal deformation in the BGA electronic packages. Electron beam moire and AFM moire fringe patterns in the BGA package are recorded. The shear strain at different solders in the package is measured. The two measurement techniques are discussed and analyzed in detail. The adaptability of these two methods is compared.
