| Abstract: | The automatic alignment technique is a key part in the development of IC packaging equipment, which brings the dicing saw new bright spot contrast to the general saw. Fully- automatic dicing saws designed by many international dominant OEM are all equipped with efficient real-time vision alignment units. To improve the saw's performance, the vision technique fit for the dicing saw is studied these years, and some achievements are got, this paper makes simple analysis according to the design principle. |
