It has just dawned on me to ask this because I'm looking at getting a reflow oven: Can I reflow the G120 module, or do I need to hand solder it into place?

@Mr. John Smith - Have you checked the manual? "10.1 Oven Reflow"

How many boards are you making? For small runs just hand solder them.

Hand soldering the G120/E is dead easy with tacky flux and a large soldering bit (4mm at least)

I just built 3 prototype boards with the G120 and hand soldered them all and they are good to go.

Well it's for mass production so, I want to be able to scale up without too much fuss. Even for the first few boards I would much prefer to re flow. It would take far to much time to hand solder those components for each machine.

The hard part about reflow with the G120 is to correctly place it without smudging the solder paste everywhere. Its pretty heavy to lift with tweezers or a suction thingy.

@hagster - So there is no flat spot where the center of gravity is. So I'd have to 3d print some sort of plastic holder if I'm doing pick and placing.

A plastic holder could realy help speed up manual placement. You could add x small holes in the main PCB to position the holder. I have thought about this idea too, not for the G120 but more for fine pitch SOMS's or BGA's
