Non-conductive adhesives (NCAs) offer cost reduction, simplicity, and flexibility over other electrically conductive adhesives (ECAs) due to an absence of conductive fillers and reduced processing requirements. However, although NCAs are a very promising potential alternative to metallic solder interconnections, there continue to be significant challenges that need to be addressed for their widespread implementation. This investigation focuses on a fundamental study of the mechanical, thermal and rheological properties of NCAs during cure process, the formation of the electrical connectivity, and the mechanisms governing long-term reliability of NCA flip chip interconnects.
