Copper Pillar VS. Solder Bump: Which is More Reliable?

Craig Hillman, PhD

CEO and managing partner of DfR Solutions


With the need for decreasing pitch and higher current densities, copper pillar has surged to the front in regards to the preferred interconnect methodology for flip chip architectures. However, while there are substantial benefits to copper pillar, there can be some misunderstandings as to the risks of copper pillar, especially under certain manufacturing conditions and field environments. In this presentation, Dr. Hillman will present the current state of copper pillar, review the variations in copper pillar offered by the marketplace, and discuss the current knowledge in regards to copper pillar reliability.
