This is the first acoustic microscope with an inverted transducer to permit scanning samples from the bottom side. Bottom-side scanning is necessary for many IGBT (Insulated Gate Bipolar Transistor) modules where top side components must be kept away from the water used to couple the ultrasound from the transducer to the sample. The D9600Z is configured to inspect two modules simultaneously via two stages with Sonomatched™ transducers and WaterPlume™ couplers.
