C-SAM model DF2400Z automated acoustic micro imaging system images and analyzes IGBT module defects. Incorporates inverted transducer. Once a recipe for scanning has been defined, the factory automation interface controls the operation.  A conveyor loads two IGBT modules onto the two system stages. Two ultrasonic transducers raster-scan each module. Ultrasound is pulsed into the module. Echo signals are received from gap-type defects. Accepts and rejects are stacked in separate locations. Accept/reject criteria are written by the user. Acoustic images reveal what type of rework is needed. Finds gap-type defects. Can image tilting and warping of module elements such as rafts.
