Title:
MEASURING METHOD AND MEASURING JIG OF SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP3042408
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To enable the electric test of a BGA (semiconductor device) which lost solder balls, and improve reliability and performance of a BGA.
SOLUTION: A measuring jig 20 is used when, after a semiconductor device wherein solder balls for mounting onto a device board are installed is mounted on the device board, the semiconductor device is again peeled from the device board, and a BGA 4 which lost the solder balls in installed on an IC socket 7 for electric test. A plurality of balls 2 enabling electric conduction between each electrode of a plurality of socket electrodes 11 installed in an IC socket 7 and the parts where the solder balls of the semiconductor device have been installed are installed.
