Abstract
A trained neural network model is used to identify anomalous solder balls in a ball grid array assembly. An x-ray system captures 3D x-ray model that is used to train the neural network model. The 3D x-ray model is converted into a colored 2D image. The image is discretized to generate a first image stack, a second image stack, and a third image stack. The image stacks are converted into greyscale images. The greyscale images are converted into a 2D color image. At least one solder ball is determined as being anomalous in one of the greyscale image stacks. At least one smaller color image patch is identified as having the at least one anomalous solder ball and at least one smaller color image patch is identified as including at least one normal solder ball. The smaller color image patches are used to train a neural network model.
