Comments on "Influence of Interfacial Compliance on Thermomechanical Stresses in Multilayered Microelectronic Packaging

An approach previously developed by Suhir in 1986 for calculating the interfacial compliance of a long-narrow strip is a general, explicit method, but Basaran and Wen claimed that there had been an error in the derivation. Using an additional approximation, they obtained a different form of longitudinal interfacial compliance. However, that approximation is not appropriate. Disregarding it, we can see that their result is the same as Suhir's result. However, a minor inconsistence in Suhir's derivation is still found. The applicability and modification of Suhir's model are discussed.
