Abstract
⺠Diffusion barrier features, activation energies of IMC growth and mechanical behaviors of electroless Co(W,P)/PbSn joints. ⺠Amorphous Co(W,P) is a sacrificial- plus stuffed-type barrier while polycrystalline Co(W,P) is a sacrificial-type barrier. ⺠Ductile mode dominates the failure of Co(W,P)/PbSn joints. ⺠Phosphorus content of Co(W,P) is crucial to the barrier capability and microstructure evolution at Co(W,P)/PbSn interface. ⺠Diffusion barrier capability is governed by the nature of chemical bonds, rather than the crystallinity of materials.
