Mounting Config. Notes

1. Ground vias are critical for thermal and RF grounding

considerations.

2. A minimum of 36 ground vias are required for 14 mil

FR4 boards.

3. If your PCB design rules allow, ground vias should be

placed under the land pattern for better RF performance.

Otherwise ground vias should be placed as close to the

land pattern as possible.

4.

Trace width depends on the PCB material.
