, and to meet the

performance targets for Thermal Interface Material in

Table 5.3

, the Heatsink Static

Compressive Load can be assessed using the items listed below:

• HP34970A DAQ

• Omegadyne load cell, 100 lbf max (LCKD-100)

• Test board (0.062") with ILM & back plate installed

• 8 in-lbf pneumatic driver

• Heatsink
