PCB manufacturing specifications

NOTES

•

USB-KW40Z includes neither J4 (the MMCX connector) nor the

external antenna.

•

For external measurements and/or external antenna usage, J4 should be

installed and soldered in place.

•

A 50 ohm MMCX connector is required; recommended part number

MM8030-2600B from Murata.

•

When selecting an external antenna to connect to the MMCX connector,

choose an antenna designed for the desired frequency band. Operation

with an external antenna may require a separate certification of your

product.

PCB manufacturing specifications

This section provides the specifications used to manufacture the USB-KW40Z development printed circuit

board (PCB) described in this guide.

The USB-KW40Z development platform PCBs must comply with the following:

•

The PCB must comply with Perfag1D/3C (www.perfag.dk/en/)

•

The PCB manufacturer’s logo is required

•

The PCB production week and year code is required

— The manufacturer’s logo and week/year code must be stamped on the back of the PCB solder

mask

— The PCB manufacturer cannot insert text on the PCB either in copper or in silkscreen without

written permission from Freescale Semiconductor, Inc.

•

The required Underwriter’s Laboratory (UL) Flammability Rating

— The UL information must be stamped on the back of the PCB solder mask

NOTE

•

A complete set of design files for the MKW40Z160 development boards

is available at the Freescale website (www.freescale.com/KW40Z)

under “Software and Tools.” These reference designs should be used as

a starting point for a custom application.

•

The Freescale IEEE 802.15.4 / ZigBee Package and Hardware Layout

Considerations Reference Manual, (ZHDCRM) is also available at the

same web site to provide additional design guidance.
