Gap Pad A2000 acts as a thermal interface
and electrical insulator between electronic
components and heat sinks. In the thickness
range of 10 to 40 mil, Gap Pad A2000 is
supplied with natural tack on both sides,
allowing for excellent compliance to the
adjacent surfaces of components.The 40 mil
material thickness is supplied with lower tack
on one side, allowing for burn-in processes
and easy rework.
Note: Resultant thickness is defined as the final gap
thickness of the application.

. 3) The ASTM D5470 test fixture was used. The recorded value includes interfacial ther-
mal resistance. These values are provided for reference only. Actual application performance is directly related to the
surface roughness, flatness and pressure applied.
Typical Applications Include:
• Computer and peripherals; between CPU and heat spreader
• Telecommunications
• Heat pipe assemblies
• RDRAM™ memory modules
• CDROM / DVD cooling
• Areas where heat needs to be transferred to a frame chassis or other type of heat spreader
• DDR SDRAM memory modules
