How to make cheap SMD rework preheater

[flolic]

Hi, I just want to share few pictures of my homemade preheater.
It is essential for BGA rework, and very helpful for any SMD rework on a larger multilayer boards.

GPU chip removed:


Solder ball stencil:


Reballed chip:


Resoldered on PCB:

Shafri, I much prefer wood grill 

Yes, that's just a normal heater. I prefer to heat the whole board because bigger boards tend to warp if heated partially.
If for some reason I don't want to heat whole board, I mask part that needs to be cool with a aluminium foil.

I really like your board holder! I was going to make something similar out of an adjustable hot air gun with a custom nozzle

is it funny when parts on the other side of the board starts falling off?

Surface tension is a magical thing

Which type heater is using

Nice mounts flolic, they are are important as the heater itself. Thanks for sharing. One idea you can consider is adding a sheet of say steel a few mm on top of the heater to diffuse the radiaton even more, which should further prevent the formation of hotspots under the pcb.

  Good evening, after seeing the tutorial, I was really excited because a station BGA cost a fortune and the basic principles of this machine is quite appealing, my question is is used a heat source on top of the graphics chip to remove or to re-weld? I await news ..
