MODULE MOUNTING RECOMMENDATIONS
I
Adequate heatsinking is required to maintain the base
temperature at 75
o
C if full rated current is to be achieved. Power
dissipation may be calculated by use of V
and r
information
and loss curves in accordance with standard formulae. We can
provide assistance with calculations or choice of heatsink if required.
I
The heatsink surface must be smooth and flat; a surface finish
of N6 (32
μ
in) and a flatness within 0.05mm (0.002") are
recommended.
I
Immediately prior to mounting, the heatsink surface should be
lightly scrubbed with fine emery, Scotch Brite or a mild chemical
etchant and then cleaned with a solvent to remove oxide build up
and foreign material. Care should be taken to ensure no foreign
particles remain.
I
An even coating of thermal compound (eg. Unial) should be
applied to both the heatsink and module mounting surfaces. This
should ideally be 0.05mm (0.002") per surface to ensure optimum
thermal performance.
I
After application of thermal compound, place the module squarely
over the mounting holes, (or 'T' slots) in the heatsink. Using a
torque wrench, slowly tighten the recommended fixing bolts at
each end, rotating each in turn no more than 1/4 of a revolution at
a time. Continue until the required torque of 6Nm (55lb.ins) is
reached at both ends.
I
It is not acceptable to fully tighten one fixing bolt before starting
to tighten the others. Such action may DAMAGE the module.
