A connecting method for pins and tin balls of an electric connector. Pins of the electric connector elastically resist against tin balls so as to position the pins. The lower ends of the pins store elastic energy due to the elastically resisting contact. During welding by blowing heated air, the elastic energy is released to push the melting tin balls so that the lower ends of the pins of the electric connector is tightly combined with the PC board.
