module removal, Vicor highly recommends the use of our
Module Exchange Tool in order to ensure that the sockets
are not damaged during the module removal process. Removing the module at an angle should be avoided as
this can damage the sockets.

Environmental SurfMate products are tested in random vibration environments to best simulate the broad
Shock and vibration spectrum of frequencies and amplitudes that may be encountered in typical applications.
Actual system resonant frequencies will depend on PCB construction and mounting details.
For critical, or unusual, shock and vibration environments, the performance of the system
should be independently verified.
