[SBE] IR vs HotAir BGA rework stn?

[Jack Davis]

The positioning of BGA devices is so critical I gave up on moving air,
sounds a bit crude but a mini propane torch is very effective.  Sometimes
the BGA junctions get intermittent and if you are really lucky you can
reconnect them by simply reheating the device.  If you have to re-ball them
that is a lot tougher to get a uniform job.  The ROHAS versions are just
plain Butt Ugly!  

 

Gotta love that lead!

This may be more of a question for the TV and repair folks.   I am looking
for some guidance on the purpose of a BGA rework station.  Anyone with
experience?
 
Do you prefer IR or hot air?
 
Any manufactuers that are preferred, or to run away from?
 
Any recommended vendors?
 
Ideally I want a unit for under $1k that includes the ability to rework, not
just reflow the target.  Rework usually includes lift, support and place of
the chip.
 
Off line reply is fine.
 
Thanks
