产品描述

LOW CTE

Low Moisture Absorption

Low lonic Impurities(<5 ppm Cl, Na+, K+)

High Temperature Stability

IDEAL FOR:

Chip or Component Bonding

DESCRIPTION:

MC7883 is a one part, quartz filled cyanate ester high temperatureadhesive. It is designed for use in both chip and component level bondingapplication to reduces stresses. It can withstand temperatures up to 350 Cwithout thermal degradation. Its unique chemistry results in very lowmoisture absorption, high adhesive strength.

MC7883 is designed to be dispensed or screen printed for bonding. Oncecured, adhesive achieves less than 29 ppm/C and higher than 6 Gpamodulus for unparalleled reliability.

AVAILABILITY:

MC7883 is available in syringes for automatic dispense applications.

APPLICATION PROCEDURES:

(1 )Thaw to room temperature before opening container.

(2 ) Dispense adhesive onto clean substrate with a suitable pattern to

(3 )Cure according to the recommended schedule

NOTE: The monomer contained in this product is subject tocrystallization even at room temperature. If product is thawed andremains crystallized, simply place in 40 C environment for as long asneeded to return product to the liquid state i.e. usually not more that15-20 minutes.
