Accuracy in solder balls and joint void detection is very important. If voids are incorrectly identified, board yield will be affected by incorrect scrapping and rework. Voids are difficult to detect using manual inspection alone. One current solution to make voids visible involves the use of a 2D x-ray system to image the boards. Some existing x-ray inspection systems have void detection algorithms that require the use of intensive, time consuming, fine tuning operations. These algorithms… Expand
Automated Void Detection in Solder Balls in the Presence of Vias and Other Artifacts
Voids are one of the major defects in solder balls and their detection and assessment can help in reducing unit and board yield issues caused by excessive or very large voids. Voids are difficult toExpand
Automated defect detection of insulated gate bipolar transistor based on computed laminography imaging
Abstract Void inspection is crucial for insulated gate bipolar transistors. X-ray computed laminography (CL) is an imaging method for plate-like objects such as insulated gate bipolar transistors.Expand

This study shows two properties: the Laplacian of Gaussian is zero at any junction and it has one or several elliptic extrema that always lie inside the junction sectors. Expand
Methods for fast morphological image transforms using bitmapped binary images
TLDR
The algorithms described in this paper are capable of performing the basic morphological image transforms using structuring elements of arbitrary size and shape, using a bitmap representation of binary images instead of representing binary images as bitplanes inserted in gray value images. Expand

Behavior of the Laplacian of Gaussian Extrema
TLDR
This paper analyses the behavior in scale space of linear junction models (L, Y and X models), nonlinear junction models, and linear junction multi-models and shows that for infinite models the Laplacian of the Gaussian at the corner point is not always equal to zero. Expand
