摘要:
A softened and compliant fillet portion of a cured polymeric underfill in a flip-chip arrangement reduces occurences of fillet crackings caused by thermal stresses. The softening of the fillet is achieved by chemically breaking cross-links in the cured polymeric underfill material using a chemical solvent. In another embodiment, the softening of the fillet is achieved by applying heat using a controllable beam of thermal energy to break up the cross-links to thereby soften the fillet.
