Tape Construction
Smooth foil backings with
3M
conductive adhesive
(aluminum), 1181 (copper) and 1183
(tin-plated copper) are smooth-backed
foil tapes that establish secure electrical
contact with the application surface by
means of a unique adhesive. Well
distributed conductive particles
in the adhesive provide a multitude
of low-resistance paths between the
backing and the substrate. (Figure 1)
The backings of Shielding Tapes 1245
Embossed foil backings
(copper), 1267 (aluminum) and 1345
(tin-plated copper) are impressed with
an embossed pattern (Figure 2) that
protrudes through the acrylic adhesive
to make direct electrical contact with
the application surface. This reliable
“through-the-adhesive” conductivity
system provides stable contact resistance
and a high level of
shielding effectiveness.
The copper used in 3M EMI Shielding
Tin-plated foil backings
Tapes 1183 (smooth backing) and 1345
(embossed backing) is plated on both
sides with tin to provide exceptional
solderability and resistance to corrosion
and oxidation. In addition, the tapes
remain conductive after oxidation.
Conductive adhesive on
3M Shielding Tape 1182 is a copper foil
both sides
tape coated on both sides with conductive
acrylic adhesive. This unique
construction offers an excellent method
of grounding and bonding conductive
surfaces. It also exhibits low thermal
resistance. Tape 1182 is supplied with
a removable liner on each side for ease
of handling.
