PCB Metal Land Pattern (Dimensions in millimeters)

RECOMMENDED LAND PATTERN

RECOMMENDED LAND PATTERN MASK

Notes:

1. All dimensions are in millimeters. Angles are in degrees.

2. Use 2 oz. copper minimum for top and bottom layer metal.

3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend a 0.35mm

(#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25mm (0.10”).

4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.

5. Place mounting screws near the part to fasten a back side heat sink.

6. Do not apply solder mask to the back side of the PC board in the heat sink contact region.

7. Ensure that the backside via region makes good physical contact with the heat sink.
