(from Nordson DAGE and Nordson MATRIX) to analyze the critical solder joints of these new-generation packages. AOI, combined with Conformal Coat and SPI inspection, are the best technologies for identifying the PCB shorts, PCB voids, opens, misalignments and solder integrity of area-array chip packages

. During this inspection step, you are checking the PCB for loose solder balls, shorts, or bridges between solder balls. The Final Step in the PCB Assembly Process Testing PCBs at various stages throughout the assembly process is essential to avoid situations where defects are found at the last moment
