Abstract
Coordinate data for the array pattern of contact pins and coordinate data for the array pattern of solder balls of an IC package is stored by a positioning section of an IC package testing device. The position of a BGA is adjusted so that the contact pins and the solder balls accurately overlap each other. The solder balls of the IC package are abutted on the respective contact pins while the IC package is sucked onto by a suction head. Then, the solder balls are abutted on the respective contact pins with an optimal load while measuring a load applied to the IC package by load cells.
