Heatsink Mounting/Hardware
Tips for Mechanical Mounting
:
1 All mounting holes are 0.156 inch thru and they are designed for a #6 Screw. Stainless Steel mounting hardware
is recommended, grade 18-8 or better. A lock washer of same material should also be used.
2 Ensure mounting surface is flat to better than 0.0025”
3 Use a thin layer of thermal compound on the backside of the PA - no more than 0.001” - 0.002” thickness!
4 Torque all screws to 10-12 in-lbs
Use of cooling air on top of pallet to keep the PCB cool is recommended but not required.
There is a thermal pad
under the output side of the PCB. Most of the heat is dissipated through the ¼ inch copper base plate.
Warning: Failure to use a proper heat sink and/or improper installation will cause the transistors to burn out. This
type of failure is not covered by warranty. This product can be ordered with a custom heat sink. Please contact
factory for more information.
