If you or your significant-other use some of the specialty tea

throw out the little cans it comes in...they can be recycled
into a variety of enclosures, shield cans, etc., if they are
made of tin-plated, light sheet steel.

Did you save any of those thin metal boxes AOL was mailing their
CDROMS in a couple years ago? They look to be just thick enough for
some small SMD designs.


Not the thin ones. About 8 years ago, the Bank of America chain
was handing out "Christmas boxes" of AOL material (including CD)
which were at least an inch and a half deep. Unfortunately, the
box lid folded over the edges of the main box part and that did
not make a good enough metal-to-metal contact along the edges.

The tin-plated steel tea and coffee boxes have plastic-paper
lids (throwaway) and the lip at the top will support a metal
or PCB cover that can be sheet-metal-screw secured in place.
Better raw material for a box to shield RF in my thinking.
Solderability is great anywhere on the surfaces, good for
making connections to the can "ground."

Me too. ["R-A all the way" :-) ]


Well, I was U-S, (Drafted, for those who don't know) but I tested out
of a three year electronics school while in basic training and was
awarded the MOS for a TV Broadcast engineer. I went straight from basic
training to working in CATV, CCTV, AML type Jerrold Microwave video
links and even a little RADAR work.
