Tpcm™ 780 is a high performance, inherently tacky, easy to rework phase change thermal
interface material. Developed specifically to meet the high thermal conductivity and low
thermal resistance requirements of today’s demanding processors.
This silicone-free material is so soft that it begins to flow as the temperature is elevated by
just a small amount. Also, since no tabs are required, Tpcm™ 780 eliminates the need for
expensive converting.
FEATURES AND BENEFITS
• M inimizes contact thermal resistance
by filling the microscopic irregularities
of the components it contacts.
Begins to soften and flow at
approximately 45ºC
• D esigned to minimize migration (pump
out) at CPU operating temperatures
using a unique material formulation
that softens, but does not fully
change phase
• S ilicone-free for applications that are
silicone sensitive
• O utstanding thermal performance helps
to ensure CPU/application reliability
• N o mess due to thixotropic
characteristics which prevent flow
outside of interface
• V ery soft at room temperature,
therefore less stress on board
during assembly
• Tabless parts make for easier handling
in the manufacturing environment
• RoHS Compliant
• 94V0 UL Flammability Rating
• Naturally tacky at room temperature,
requiring no adhesive
• Heat sink preheating not required
• Exceptionally high reliability during
storage and after installation
APPLICATIONS
• Graphics Cards
• Notebooks
• Desktops
• Servers
• Memory Modules
• Automotive
• IGBTs
TABLESS PARTS
Easy handling in manufacturing
environment/rapid handling
Eliminating risk of top tab being left in place
during assembly
Minimum part size is 8mm x 8mm (smaller size
may be available via engineering approval)
Thicknesses are 0.016 inch (0.406mm) and
0.025 inch (0.635mm)
TABBED PARTS
Marked tab reduces risk of top tab being left
in place during assembly
Tab provides protection from dust and other
contamination during application of pads and
shipping of applied pads
Minimum part size is 10mm x 10mm (smaller size may
be available via engineering approval)
Thicknesses are 0.008 inch (0.203mm) and 0.010 inch
(0.254mm)
