Chip packaging is an important process during IC manufacturing. Wire bonders are key equipments of chip packaging. The manually type of wire bonders can be updated to automatic with a pattern recognition system (PRS). However, the resolution of PRS is quite sensitive to the mechanisms trembling. Additional waiting time has to be taken before the image sensor can take a shoot, which limits the wire bonders productivity. In this paper, method for motion blurred image restoration is presented. The method uses point spread function (PSF) learning to estimate the degradation function and power spectrum analyze to estimate the images signal to noise rate (SNR). Experimental results are given to illustrate the proposed image restoration algorithm.
