Abstract
A new single camera vision system for online coplanarity inspection of SOP (Small Outline Packaging) IC leads is presented. First, a novel imaging optical structure with multiple reflection mirrors and a total reflection rectangular prism is developed. This structure characterized in that two side views of IC leads are captured one-time in a small FOV (Field Of View). Second, a fast high-precision algorithm to inspect the coplanarity of IC leads is also proposed. Based on the statistical method, the “3Sigma” criterion is used to judge the quality of IC leads’ coplanarity. Finally, the experimental results indicated that the proposed system can inspect IC leads coplanarity in real-time.
