This is a testsetup for Surface mount soldering,
Desoldering. It is a failure.
Two heating elements in the bottom and fans for
fast cooling.
There was,is several problems with this approach:
1. Applying tinn paste at the very little point of
soldering. Using a mask in thin steel is the standard
solution, expensive for singel use. Using syringe
failed.
2.Fasten the component at the exact spot while soldering was difficult - applying glue etc.
3.The heating curve for succesfull ironing requires
fast heating and cooloing was very hard to accomplish.

In many cases, with the right pin configuration
manuell soldering results in good connections.f
