DESCRIPTION
Interpoint's 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 in
2
/W (129C mm
2
/W) thermal resistance path.
M
ATERIAL
The Thermal Mounting Pads, made of silicon rubber and fiberglass,
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.
M
OUNTING
For maximum thermal conduction from the converter through the
thermal pad to the thermal plane, a mounting pressure of 300-600
lbs/in
2
is recommended. To achieve this level of mounting pressure,
Interpoint recommends 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).
