A first extending portion 32 of the upper surface 21 and a first mating portion 33 extending upward from the first extending portion 32 are used to abut the solder ball 201 of the first electronic component 200. Specifically, the vertical cross section of the first mating portion 33 is V-shaped, so that the first mating portion 33 is in contact with the solder ball 201 at two points, and two upper terminals 3 are provided to clamp one The solder ball 201 thus has four points of contact with the solder ball 201, the holding of the solder ball 201 is more stable, the contact is firmer, and poor contact between the upper terminal 3 and the solder ball 201 is avoided. Two upper terminals 3 are arranged to clamp one lower terminal 4, thereby forming two conductive paths arranged in parallel between the chip module and the circuit board to ensure that the chip module and the circuit Good electrical conductivity and signal transmission performance between boards.
