Dye and Pry involves cleaning a sample to remove debris and flux around solder, then exposing it to a red dye by immersion. The sample is then exposed to either vacuum or pressure to ensure the dye penetrates into all cracks, separations and surfaces with exposure to the outside of the device. The parts are then baked in an oven until fully dry. The ink must be fully dried to avoid smearing later. The device is then separated by prying or flexing of the PCB. The interfaces now separated are inspected optically. Failure sites are imaged and identified.
