Yes I just made a former out of 1/4" thick 'Tufnol' that measured 34mm x
13mm which is good for the two outer shields.
Then using 0.005" thick brass foil I marked out the shapes of the shields
34mm x 13mm and added 4mm tall sides to fold down. (see pics)
I carefully folded the foil over the former and bent the little tabs round
over the ends and soldered the flaps down.
Easy with ordinary soldering iron as the brass is so thin.
Once the shields were fabricated I rubbed them back and forth on a smooth
flat file to make sure all the sides were flush with the pcb.
ie filed off any high spots.
I then kept offering the shields to the pcb and marked out where I needed
to file away the side to avoid the SMD components going to the audio codec.
I then 'tinned' the edges with solder and tinned the 'fixing pads' on the
board.
Carefully lined up the shield and tinned one corner in place.
Final adjustments and then soldered the other pads.
Phew!
