I think the main cause of this condition is #3 because both #1 and #2 never change from board to board, these are identical boards with identical BGA revisions. These BGA's (as stated before) are about 3 years old.. I don't believe they are lead free

Joe: I know this is not the correct forum to post chip "reworking" questions. Reply: Rework questions are as appropriate as the next topic here on SMTnet J: BGA will not reflow at any normal temperature level. I believe these chips may have been gen

Contact your local Juki distributor. But as a reseller of used equipment they may not be too willing to help out. And why would you want to add the expense and hassle of adding a glue head on a machine?

next step, if the nozzle have to take the same component, the nozzle is going to take it and the both components stick together(one over the other) and the nozzle places them like this stick together. So there is nothing in one place, and on another
