shielding

FYI: For shielding, I apply self-adhesive copper tape to the inside of inexpensive plastic project boxes.
$3.59 for a 3x120 inch roll.
The applied strips can be soldered together for wider boxes.

the 3M copper foil tape has a conductive adhesive. No soldering required

I have not found standard copper tapes to be especially effective at
shielding; they may help at seams.

If you can, test your unit with external fields before and after, and see
if there is a difference.

(I, too, was surprised how ineffective tapes were for certain
applications. Tapes come in at least a dozen specs, some with conductive
glue, some without, different frequency ranges, and more).

A lot of EMI/EMC problems aren't fixed by shielding, if there's holes or
wires poking through it.
