The process is that they just remove  the entire solder balls and flattened out the entire bump terminal then  replace the chips again. It may work but not totally effective as like  for my years experience for the soldering process is too weak  and easy  to break , because the amount of soldered balls  that holds the chips is  not strong enough to hold it.  Althought reballing IC's is not that easy for beginners to tackle to. it  needs training and proper procedures to follow, further we will  discuss  the easiest way on how to reball IC chips. <a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=reballingkit.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/reballingkit.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>These are the kits you must prepare to be able to proceed in reballing BGA chips.A Solder Balls Solder balls have different sizes and measured by diameter,that match on every chips bumps sizes also.These are the common Soldering Ball diameter ranges for mobile phones chips.0.05, 0.10, 0.15, 0.20, 0.25mm, 0.30mm, 0.35mm, 0.40mm,0.45mm,0.50mm ,0.55mm ,0.60mm, 0.65mm,  0.76mm <a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=solderballs.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/solderballs.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A BGA Stencil Pattern PlatesThis is being used to properly align the solder ball on every bumps of the chips.<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=bgastencilkit.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/bgastencilkit.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>every chips have different bumps pattern and alignment designs.<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=stencilpattern2.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/stencilpattern2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Spatulathis is used to gathered the  solder ball on each holes of the Stencil plates.<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=spatula.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/spatula.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A liquid Flux<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=liquidsolderingflux.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/liquidsolderingflux.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A PCB Board Holdera PCB holder is being used to maintain the accuracy while working  soldering and to avoid gripping and misalignment of solder balls.<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=pcbholder.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/pcbholder.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A Cleaning liquid Too many cleaning product offered today that is non flammable.   A lacquer thinner will work, and still widely used for many mobile phone technician. <a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=lacquer.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/lacquer.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A cotton buds<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=cottonbuds2.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/cottonbuds2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>A Brush<a href="http://s946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/?action=view&current=tootbrush.jpg" target="_blank"><img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20repair%20tutorials/tootbrush.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></blockquote>
