Compute module soldered to the main PCB

[JRos]

Hi,
Has anyone made experience with soldering the Compute Module directly to a PCB?
I know that it is intended to fit the device in a DDR2 SODIMM socket. But if a removal of the Compute Module is not planned, the socked could be saved.
So, are there arguments against soldering?

Put it in a SODIMM socket then hot-glue it in there. The SODIMM connector is double sided so you can't just solder it to a board.

The essential pins are duplicated on either side of the connector (VBAT, 1V8, 3V3 etc)
- so it is possible to use only one side, depending on what other features you want to use.

Small designs are available with the socket though:

How do you want to save money? Socket is placed by pick & place machine, soldered in reflow oven.
How do you want to solder the Compute module to your board as reflowing it might not be possible...

And... How many thousands of units to be build?
