Silver Epoxy Electronic Modules Flat Cable High Frequency Shields, 906, 2.5gm

Description

Technical Product Bulletin
SILVER EPOXY ELECTRICAL CONDUCTOR
PRODUCT DESCRIPTION:
AA-DUCT 906
represents the newest technology since the introduction of electrically conductive silver compounds. This
unique formulation is
based on a silver coated ceramic that results
in lower material costs without adversely sacrificing
the properties obtained with a pure silver
formulation. This concept opens the door to a wide
range of applications
previously prohibited
by the much higher cost of conventional silver
conductive.
AA-DUCT 906
cures at room temperature or can be accelerated with mild heat to form a tenacious bond between similar
and dissimilar substrates
such as aluminum, copper, magnesium,
steel, bronze nickel, ceramic, glass, phenolic, and G-10
epoxy glass boards.
AA-DUCT 906
, because of its excellent continuity, has been used extensively in such diversified
applications as, microwave EMI and RFI
shielding, in the assembly or repair of printed
circuit boards, wave guides,
electronic modules, flat cable, high frequency shields, connections,
and circuitry and as a cold solder. This unique
formulation offers ease in handling due to
its creamy consistency and versatile application by
hand, automatic dispenser,
silk-screening, transfer
or stamping techniques.

GENERAL INFORMATION:
For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).
HOW TO USE:
1)
Carefully clean and dry all surfaces to be bonded.
2)
Apply
AA-DUCT 906
completely mixed adhesive to the prepared surfaces, and gently press these surfaces together.
Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
3)
Some separation of components is common during shipping and storage. For this reason, it is recommended that the
contents of the shipping container be thoroughly mixed prior to use.
4)
Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle
warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components
do not react as well as liquid components and should be re-dissolved prior to use for best results.
AVAILABILITY:
This epoxy can be supplied in various different packages.
