Technical Bulletin
System Design and Performance for 3M
Thermally Conductive Tapes 9882, 9885, 9890
Notes on System Design
and Performance
This publication is intended to aid the user in optimizing the design and performance
of systems using 3Mª Thermally Conductive Tapes 9882, 9885, and 9890.
Note: this information presented should be considered representative or typical and
should not be used for specification purposes. The user is responsible for evaluating
the tape under actual conditions of use and with the substrates intended for the userÕs
application, to determine whether the tape is suitable for a particular use and method
of application.
The information of this bulletin is organized in three sections:
I. Thermal and Mechanical Performance Optimization
II. Performance at High and Low Temperatures
III. Bond Building / Rework
Additional information on these topics or others not covered may be requested by
calling the toll free number on the last page.
