Productivity
• Tapes bond with light pressure
and have immediate tack
• Avoid the mess, hassle and cost
of greases and clips*
• Eliminate long cure times and
fixturing of liquid adhesives
• Can be die-cut and pre-applied to
one surface for later bonding
Reliability
• High mechanical strength for
securely attaching heat sinks and
heat spreaders
•
Elastomeric properties of
adhesive provide
excellent
shock performance
• High dielectric strength provides
electrical isolation
• Tape provides high degree of
thickness control
Performance
• Improved surface wetout lowers
thermal impedance
• Pure adhesive film construction
means no carrier to hinder gap
filling
• No carrier also means fewer
material interfaces, a leading
cause of poor thermal performance
