A surface-mounting structure of a surface-mounting electronic device onto the surface of a circuit medium is provided. An external terminal of the device has a first mounting surface on which a first set of protrusions are formed. The first mounting surface includes a first uncovered space in the remaining area of the first set of protrusions. A mounting pad of the circuit medium has a second mounting surface on which a second set of protrusions are formed. The second mounting surface includes a second uncovered space in the remaining area of the second set of protrusions. The second mounting surface is opposite to the first mounting surface. The second set of protrusions are inserted into the first uncovered space. The first set of protrusions are inserted into the second uncovered space. A bonding material is placed between the first and second mounting surfaces. The bonding material provides a mechanical engagement between the first and second mounting surfaces, thereby mechanically and electrically connecting the terminal of the device onto the mounting pad of the circuit medium. The mounting process and its process control are simplified, and connection accuracy and reliability are improved.
