In this paper, we introduce an automated Bayesian visual inspection framework for printed circuit board (PCB) assemblies, which is able to simultaneously deal with various shaped circuit elements (CEs) on multiple scales. We propose a novel hierarchical multi-marked point process model for this purpose and demonstrate its efficiency on the task of solder(More)
The size decreison of passive components nowadays reaches 01005 dimension. For larger components also, but for these tiny components the accuracy of the component placement machines is a very important variable in respect of the placement quality. There are other variables that affect the placement quality (the quality of the solder paste, or the adhesive(More)
Automatic Optical Inspection (AOI) or Automated Visual Inspection (AVI) is a control process. It evaluates the quality of manufactured products with the help of visual information. Amongst its several uses, one is the inspection of PWB (Printed Wiring Boards) after their assembling sequences i.e. paste printing, component placement and soldering. Nowadays,(More)
Automated Optical Inspection (AOI) is a useful tool for assessing workmanship compliance in production PCB assembly environments. With advanced lighting, optics, and image processing capabilities, the machines greatly enhance inspection repeatability, accuracy and throughput. The in-line automatic optical inspection machines usually are not accurate enough(More)
