The superior machines typically use only a split vision system which allows two pictures to be viewed simultaneously. The PCB (pads) and the underside (balls) of the BGA can be observed. By using micrometer screws, both exposures can be adjusted exac

Yes of course we are doing placement of BGA's with an IPII. However there is no front lighting so you can not inspect the balls. If the silhouette is square enough there is no problem with alignment. Just use the largest nozzle that will fit on the p
