Abstract

Recently several low‐cost alternatives for flip‐chip interconnection technology have been investigated. The scope of this paper is a reliability study of flip‐chip assemblies on various substrates (mainly FR4). The deterioration (characterised by the electrical resistance) of isotropically conductive adhesive and of solder (63Sn37Pb, 96.5Sn3.5Ag) bumps caused by both thermal cycling and thermal shock will be described. These investigations confirm that in the low‐cost flip‐chip technology there is practically no reliable bump interconnection without using an underfill material.
