Abstract: An in-circuit test fixture performs both electrical tests on a Printed Circuit Assembly (“PCA”) and reads distinguishing features of a feature of interest of the PCA. The in-circuit test fixture physically supports an image sensor array. A light focusing means has a position relative to the distinguishing features and the image sensor such that a focused real image of the distinguishing features is imaged onto the image sensor. The image sensor outputs image information of the distinguishing features. A processor performs image analysis based on the image information of the distinguishing features to determine if defects exist.
