BDN21-3CB-A01 Datasheet, PDF (1/1 Pages) CTS Corporation – Adhesive peel and stick heat sinks

CTS®
W±0.01
With pre-applied adhesive, just peel
off the release liner and press onto the
component
Reduces assembly costs; no more
messy adhesives or greases required
Excellent mechanical bond
Thermally optimized pin fin
Omnidirectional
Adhesive shear strength at 100°C is
36psi (a one inch square heat sink would
require a 36lb. force to remove heat sink)
Applicable for BGA, PGA, PLCC,
and QFP packages
