If your pick and place can handle the part placements, you are most of the way there. X-Ray for Inspection of BGA and other bottom terminations = $60K(USD) and up. BGA Rework Station $40K and up. You can reball most any BGA with your Rework station.

OSP board finish is the issue. With OSP microBGA board, we need to have enough paste (enough flux) on pads (small pads on BGA), also we need to have strong, more activate flux to get rid of Preservative layer on top of pads. In this case, the OSP did

Dear all, Recently, we run 2 models with heat sink attachment on top of this BGA(on top of this BGA, there is flip chip attached at the center of the BGA). Hence, the center of the BGA is higher than corner/side. We used conventional way to attach

Does anyone have information pertaining to re-balling BGA components using balls that are preformed onto disolable paper waffers (mini BGA reballing kit)? The paper containing the specific BGA device/pattern would be placed onto the BGA then process

As you are aware the common method to rework BGA is : 1. Remove BGA with hot air reflow machine ( SRT as current practice) 2. Clean the BGA pad using solder iron and solder wick. 3. Replace BGA with SRT rework machine. The problem we have with

I would not recommend doing BGA soldering with only a hot air gun. I have done it in the past, but the boards would eventually come back from the field because the solder joints did not form correctly and the BGA would have to be reworked again. I
