MOUNTING PRESSPAKS TO HEAT DISSIPATORS
The following instruction is essential for maintaining low,
stable thermal and electrical resistances associated with
the PRESSPAK to heat dissipator surfaces.
1. INSPECTION OF MATING SURFACES
Check each mating surface for nicks,scratches and surface
finish.The PRESSPAK surface has a total indicator reading
TIR < .0005 inch and surface finish 32 prior to factory
electrical test in pressure fixtures. The dissipator
surface should be equally as good.The TIR of a fully
tested PRESSPAK may run higher but not exceed 0.001
inch (**) not including some minor nicks and scratches
associated with the test fixtures. Any bow created by
clamp system at assembly must keep flatness within 0.001
inch.(**)
(**) .002 inch for 77mm PRESSPAKS
2. SURFACE DEOXIDATION AND CLEANING
Although plated surfaces are recommended for aluminum and
copper heat dissipators, bare surfaces may be used if
careful attention to cleaning and treating is assured.
Plated surfaces and PRESSPAKS should be lightly sanded
with 600 grit paper, then oil or compound applied as
recommended. Unplated aluminum surfaces should be
vigorously abraided with a fine wire brush or 3M
"Scotchbrite" coated with Alcoa EJC #2 compound. The EJC
# 2 should be removed and the recommended compound
applied.
3. FINAL SURFACE TREATMENT
Apply silicone oil or a very thin layer of grease or
compound as indicated below. Rotate the PRESSPAK to
properly distribute the applied agent.
. bare copper
- use G322L or LS2037
. bare aluminum - use EJC #2 or G322L
. tin plated copper or aluminum
- preferably reapply DC550 or SF1154
- alternatively use G623 or G322L
. nickel plated aluminum - use DC550,G623 or G322L
. silver plating - not recommended
Recommended silicone oils are SF1154 or DC550
(200 centistoke)
4. MOUNTING
Assemble with specified mounting force applied through a
self-leveling swivel connection. The diameter of the
swivel should be preferably equal but not smaller than
the poleface diameter of the PRESSPAK. Center holes on
the top and bottom of the PRESSPAK are for locating and
positioning it to identical holes anticipated at the
heat dissipator surfaces using 1/8"dia 3/16" roll pins.
NOTES:
Silicone oil DC550 (200 centistoke) is a
product of DOW CORNING; clear silicone grease
G623, yellow G322L and SF1154(200 centistoke)
GE Silicones Waterford NY; EJC# 2 from ALCOA
and black LS2037 from ARCO , 7301 Bessemer Ave.
Cleveland OH.
Limit maximum joint temperature to:
- 95 C using EJC #2
- 150 C using SF1154,DC550 or G322L
5. APPLIED MOUNTING FORCE
The selection of an appropriate commercially available
spring clamping hardware* should consider eatablishing
and maintaining the specified mounting force over the
operating temperature range and operating life of the
PRESSPAK.Thus essential ratings such as thermal resit-
ance ,di/dt,surge current and thermal cycling will not
be impaired.
Specified forces for this product are as
follows:
7000-9000 lbs.
31.1 -40.0 kN
* Consult factory for recommendations or more detailed
instructions.
