DESCRIPTION
Our accessory Thermal Mounting Pads (TMP) provide a simple
and effective method of ensuring a low thermal resistance path
between a DC/DC converter and its mounting plane. When placed
between the converter and circuit board or heat sink, it will provide
electrical isolation, fill small surface irregularities, and produce a
0.20° C in²/W (129°C mm²/W) thermal resistance path.
MATERIAL
The Thermal Mounting Pads, made of silicon rubber and fiber-
glass, are thermally stable and non-flammable. They are non-toxic,
do not require grease and do not exhibit the cracking problems of
ceramic materials. The pads may temporarily react to some
cleaning agents (notably chlorinated hydrocarbons) by swelling,
but are not damaged after the solvent is removed. They will
tolerate soldering process temperatures.
MOUNTING
For maximum thermal conduction from the converter through the
thermal pad to the thermal plane, a mounting pressure of 300-600
lbs/in² is recommended. To achieve this level of mounting pres-
sure, we recommend using our flanged models. The formula to
calculate the recommended pressure is P=(T*N)/(0.2*D*A); where
P=pressure in PSI, T=torque, N=number of fasteners, D=fastener
diameter (in inches), A=contact surface area (in square inches).
