Abstract
A low-temperature solid-state bonding technology using palladium-coated Co micro-nano cones array (MCA) and Sn-3.0Ag-0.5Cu (wt%) solder was investigated. The Pd modification layer on the surface of Co MCA reduced the growth of oxide film. Low-temperature solid-state bonding was achieved using Co/Pd MCA under the bonding condition of 750 gf, 175 °C and 150 s with the shear strength of 49.55 MPa, and there was no void found along the bonding interface. Microscopic observation revealed that Co/Pd MCA was fully embedded in the soft solder. The average shear strength of the bonding joint was measured and demonstrate that Co/Pd MCA has higher reliability than Co MCA. This work highlights the advantages of bonding based on Co/Pd MCA, which has great potential for extensive practical applications.
