If a reflow doesnt fix it, remove and reball with lead based solder and re-attach with a lead based solder profile.

If that still doesnt work, the chip is duff. Remember to check whether replacement chip has lead or lead free balls and use appropriate profile.

Obviously, if you dont have equipment to reball, you need to go straight to replacement.


height that you use? , Upper Heater for not leaving the blistering chip.
