Abstract:
An IC package testing device, comprising:a measuring unit having a socket including contact pins to contact with solder balls in an IC package for measuring electrical characteristics of the IC package, said measuring unit located at a first location; a camera unit located at a second location for imaging a positional pattern of the solder balls in the IC package; an image recognition unit which recognizes an image obtained by the camera unit, processes the image, and obtains a positional pattern data of the solder balls; a first memory unit for storing the pattern data of the solder balls; a second memory unit for storing a positional pattern data of the contact pins in the socket, as provided by a preparation (calibration) process to translate said positional pattern data of the contact pins located at said first location relative to said second location; an adjusting unit for adjusting a position of the IC package so as to align the positional pattern of the solder balls with the positional pattern of the contact pins at a positioning section located at said second location; and a carrier unit for holding the IC package which has been adjusted the position thereof at the positioning section, and carrying it from said second location to the socket at said first location and contacting the solder balls on the contact pins.
