On the Voyager series, they are not spot-welded. They simply lay (in a row of 5 connected by a common strip of sheet metal) on top of the circuit board. There is a large tape that goes across the whole face of the PCB that holds all of them down.

I'm in the process of writing up how I replaced a damaged LCD module (from a donor 12C) on a 16C, including how I re-used the existing plastic pins to heat-stake the PCB back to the upper with great success. But with such details, it's going to take me some time (weeks maybe). Feel free to ask questions in the meantime.
