Abstract: A surface mounting structure and a packaging method thereof comprises a chip, a first conducting wire and a second conducting wire. The two conducting wires instead of lead frame architecture of the prior art is that the lead frame and a bridge jumper connected with N junction and P junction instead of the two conducting wires. The two conducting wires are drawn out from a bottom of a package, and are pressed and bent to original surface of the surface mounting pins so as to increase space utilization rate. Thereby it is to improve a complicated lead frame architecture of the prior art, increase use space and simplify system design.

Abstract: A semiconductor package structure includes a substrate, a chip module, a lead frame, and a bridging element. The chip module is electrically connected to the substrate. The lead frame is disposed beside one side of the substrate, and the lead frame has a projecting block unit.
