Title:
BONDING WIRE INSPECTION DEVICE
Document Type and Number:
Japanese Patent JP3184640
Kind Code:
B2
Abstract:
PURPOSE: To provide a bonding wire inspection device capable of making both an inspection by image processing and a visual observation on a bonding wire, and making the high-precision inspection.
CONSTITUTION: A bonding wire inspection device is provided with an image pickup device 5 for photographing the bonding state between a semiconductor chip 3 and a lead frame 2 to obtain an image, a processor 9 making an inspection based on the image obtained by the image pickup device 5, and a stereoscopic microscope 1 provided near the image pickup device 5 as an observing device. A specific semiconductor chip is photographed by the image pickup device 5, then it is conveyed to the observation area of the stereoscopic microscope 1 by a conveying mechanism 4.
