We study the precise positioning of IC (integrate circuit) chip solder bridge in this paper. Image edge detection algorithm based on wavelet transform is a promising and effective algorithm among many edge detection algorithms. In this paper the principle of wavelet transform is applied to precise positioning of IC chip solder bridge, a method of small goal detection algorithm is proposed, this detection method can accurately detect and position the tiny solder bridge from the single frame image, and it is practical and effective. Comparing to searching the whole image, it greatly enhances the detection speed.
