Reduce IC Packaging Costs with Screen-Printable B-Stage Epoxy
B-stageable thermally conductive Epoxy adhesive increases product performance and controls manufacturing costs.
Tyngsboro, MA (PRWEB) September 9, 2005 -- The application team at Creative
Materials, Inc., has introduced a screen-printable, b-stageable, highly
thermally conductive epoxy adhesive for integrated circuit (IC) packaging. This
material is designed to increase product performance through the use of
b-staging, while reducing manufacturing costs through screen-printing. Creative
Materials’ 122-07(SP) features excellent thermal stability, outstanding chemical
resistance and excellent high temperature properties. The thermal cure cycle
produces cross-linked, void free bonds.
B-stage is an intermediate stage
in the reaction of a thermosetting resin where the adhesive softens when heated
at a low temperature (110°C -125°C) for a brief time period (minutes) and is
non-tacky when cooled to room temperature.
At this stage the adhesive is
not fully cured. With B-staging, the product can be held for a period of time
prior to curing, without sacrificing performance. Attempts to use traditional
epoxies in IC manufacturing have often created expensive production bottlenecks,
because the components had to be assembled and cured immediately in small
batches. B-staging eliminates these bottlenecks by allowing the IC manufacturing
to proceed efficiently, with operations performed on larger
batches.
B-staging provides the added advantages of a very thin bond line
that helps in the dissipation of heat and provides flexibility for mismatched
substrates. Performance of Creative Materials’ 122-07(SP) is increased by
allowing solvent release without advancing the resin cross-linking. After
b-staging, the adhesive and substrate can be held for a period of time before
bonding, thus reducing the tendency of the adhesive to flow beyond location of
application.
Creative Materials’ 122-07(SP) employs the cost effective
technology of screen-printing that enables high volume manufacturing.
Applications for this material include, but are not limited to, die attach,
printed circuit board fabrication, advanced material composites, sealing, and
high performance coatings.
