Mounting Instructions

The data shown was taken on a 31mil thick FR-4 board with

1 ounce of copper on both sides.

The board was mounted to a baseplate with 3 screws as shown.

The screws bring the top side copper temperature to the same

value as the baseplate.

1. Use 1 or 2 ounce copper, if possible.

2. Solder the copper pad on the backside of the device

package to the ground plane.

3. Use a large ground pad area with many plated through-holes

as shown.

4. If possible, use at least one screw no more than 0.2 inch

from the device package to provide a low thermal resistance

path to the baseplate of the package.

5. Thermal resistance from ground lead to screws is

2 deg. C/W.
