Abstract

The emergence of surface mount technology (SMT) has created new challenges. The most challenging is the need for more capable system to monitor the product quality. Currently, the most popular method is based on machine vision for automated optical inspection (AOI). But they generally only work in 2D testing mode, cannot make a more objective assessment for solder joints. This paper describes a three-dimensional (3D) inspection system based on recovery of the surface of solder joints. Contents include four parts: combinate wavelet packet image denoising, and different filtering methods, the mixed denoising method of SMT solder joint image is studied; the 3D illumination model suitable for SMT solder joint reconstruction is presented; based on SFS technology, the 3D reconstruction technology of solder joint was studied; the 3D solid model and morphological parameters of solder joint were obtained. This paper resolved the problem of SMT solder joint 3D quality information automatic extraction. The results can provide 3D quality information for SMT solder joint quality comparison, analysis and intelligence discrimination of solder joint quality.
