In his paper, entitled “Detecting and Analyzing Wafer Bump Voids with X-ray Inspection,” Frank discusses X-ray imaging technology that can detect and measure voids within solder bumps on chips and determine the viability of the component, based on pre-set threshold values. In this way, the X-ray inspection system converts 3-D voids to measurable 2-D images, enabling the system to calculate the ratio of the size of the void, or voids, within a solder bump to the total mass of the ball. The system can also determine the largest linear distance between two points in the void and compare the result with the diameter of the ball.
