document: Automated post bonding inspection by using machine vision techniques Inspection plays an important role in the semiconductor industry . In this paper , we focus on the inspection task after wire bonding in packaging . The purpose of wire bonding -LRB- W/B -RRB- is to connect the bond pads with the lead fingers . Two major types of defects are -LRB- 1 -RRB- bonding line missing and -LRB- 2 -RRB- bonding line breakage . The numbers of bonding lines and bonding balls are used as the features for defect classification . The proposed method consists of image preprocessing , orientation determination , connection detection , bonding line detection , bonding ball detection , and defect classification . The proposed method is simple and fast . The experimental results show that the proposed method can detect the defects effectively
