  • Published : 2002.10.01

Abstract

. A high peak power demand at substations will result under This paper deals with the detection of defects at BGA solder joints in PC boards by using X-ray Imaging. . To improve a cost performance and reliability of PC boards, an inspection of BGA is required in the surface mount process. . Contents 2 We attempt to detect the characteristic of the solder bridges based on an image analysis.
