HLY: If you must build product while you wait to get the printer fixed, and if the BGA balls are eutectic solder, your approach is a good one. All solder paste does in this assembly application is supply the flux. Additional solder volume is not ne

I have a product with mixed in Pb free and Pb BGAs. I decide to use SnPb paste with Pb free reflow profile to make it work for both types of BGA. Do I have a reliability solder joint issue by using this method? How is your opinion on this case? Can

I don't understand why you think a BGA would be better than a QFP. Half the process questions I see on this forum seem to deal with BGA's, and the switch to Pbfree processing is a far greater hassle - Pb free QFP's will be compatible with either pro

Hello, recently we changed supplier of the LF BGA, we did corossection and now have doubts... previous BGA specs : pitch 1mm, ball diameter 0.6mm future BGA specs : pitch 1mm, ball diameter 0.4mm on the crossecrion we found that one of the ball seem

Hi Krish, thanks for your detailed reply. Sorry I assumed you may be using a solder paste to solder the BGA to the pcb. Either solder paste or Gel flux is best for resoldering BGA to pcb. Are you using Gel flux ? Most popular long term storage for mo

You have not mentioned exactly how the BGA was reflowed onto the board. Was it sent through the oven again after the mini-stencil, or was it heateed up and reflowed using a BGA rework station, or other hot air device?? From the sound of it (outside

Being in the line of BGA rework and having performed much rework on boards that go into military planes, I can give you an opinion from a practical background rather than an in depth study. Basically BGA's have caused many of my customers big headac

| Dear all, | | What are your views on reworking BGA's? I mean, with the BGA going through reflow temperatures four times or more, and with a manual reballing process, wouldn't it raise up a few reliability issues? Would you consider not doing rew

Hello there, I am currently doing BGA repair and basically I am applying the same process as Mike sujested. It is actually the way to go when creating a profile. The next process is re-balling your package, that is if you whant to use the same compon
