    Identifying locations of Solder-Balls

    Seems difficult to identify all the possible solder-balls that can result from SMT and Reflow processes. Also not always will all the solder-balls stuck to the bases of parts wash out. So then I guess only an additional visual inspection could identify them. But I'm wondering if the pixel-data...
