Copper Foil Shielding Tape
Mark Zenier
for putting a ground plane on bare Vectorboard.
It's a metal foil (tinned copper ?) tape that is 1/2 inch wide, with a
quilted pattern embossed in it. The cardboard spool in the center
says 3M.
The punchline is that a trip to the local R.S. store brought forth
a few blank looks and the statment that if it isn't in the catalog
any more, then we don't have it.
Anyone know what this stuff really is?

It's just what you thought, foil tape for shielding. There is a whole
variety of types available many of them copper. The type with the quilted
pattern usually has conductive glue. I use it mostly during the bread-board
phase for shielding between high gain sections when necessary. It also comes
in handy during FFC testing to help identify problem 'holes' emitting
excessive RF. I have used it to provide some ground plane on vector board
however the heat of soldering tends to do a number on the glue. It's usually
pretty expensive stuff as well.

Well, I found a similar item at a hobby store a few years ago and have been
using it to run power rails and ground planes on proto boards. The stuff I
found was intended to be DOLL HOUSE WIREING! The idea was to lay the traces
on the walls and ceilings of the doll house. Then you attach the lights which
have staple-like contacts. You then paint over the traces. It comes in rolls
ov 50 yards (and other sizes I'm sure) and about .25" wide, which is convenient
for running grounding planes under 300 mil packages.

This is possibly the 3M 1345. The adhesive isnt actually conductive but the
embossing pattern penetrates the adhesive for a metal to metal contact. The
3M 1181 is smooth and conductive via metal particles in the adhesive. 3M has
a flier about their alum and copper Foil Shielding Tapes, I think the
publication number is 80-6102-1775-6. (my guess the 80- means it was printed
in 1980 so it may be out of date ;-) Try calling their customer service @
800-233-3636.
There are lots of other manufacturers to that make copper foil products, some
insulated, some not: Permacel, Mystic, Tefco, Tapecon, Advance Electrical
Sales (maybe only a local dist), Fralock, plus many more I'm sure.
