PCB manufacturing specifications • • • • 5 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 level is 94V-0 ((http://ulstandards.ul.com/standard/?id=94) — The UL information must be stamped on the back of the PCB solder mask • • 5.1 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. Single PCB construction This section describes individual PCB construction details. • The USB-KW40Z PCBs are four-layer, multi-layer designs • The PCBs contain no blind, buried, or micro vias Freescale USB Development Board USB-KW40Z User’s Guide, Rev. 0, 10/2015 Freescale Semiconductor, Inc 21 PCB manufacturing specifications • PCB data: — USB-KW40Z size: Approximately 18.5x 61.4 mm (0.73 x 2.42 inches) — USB-KW40Z final thickness (Cu/Cu): 1.57 mm (0.62 inches) +/- 10% (excluding solder mask) Table 3 defines some of the layers of the completed PCB.

As a result, RF component placement, line geometries and layout, and spacing to the ground plane are critical parameters. Therefore, BOARD STACKUP GEOMETRY IS CRITICAL. Dielectric and copper thicknesses and spacing must not be changed; follow the stackup information provided with the reference design (see Figure 19) information provided with the reference design. Figure 19. USB-KW40Z PCB stackup cross-section (four layer) • • 5.2 Solder mask is required Silk screen is required Panelization The panel size can be negotiated depending on production volume. 5.3 Materials The PCB composite materials must meet the following requirements: • Laminate—the base material (laminate) must be FR4. If the laminate material is changed, the RF electrical characteristics may change and degrade RF performance. Freescale USB Development Board USB-KW40Z User’s Guide, Rev. 0, 10/2015 22 Freescale Semiconductor, Inc. PCB manufacturing specifications • • 5.4 Copper foil — Top and bottom copper layers must be 1 oz. copper — Interior layers must be 1 oz. copper Plating—All pad plating must be Hot Air Levelling (HAL) Solder mask The solder mask must meet the following requirements: • Solder mask type: Liquid Film Electra EMP110 or equivalent • Solder mask thickness: 10–30 µm 5.5 Silk screen The silk screen must meet the following requirements: • Silk screen color: White • Silk screen must be applied after application of solder mask if solder mask is required • The silk screen ink must not extend into any plated-thru-holes • The silk screen must be clipped back to the line of resistance 5.6 • • 5.7 Electrical PCB testing All PCBs must be 100 percent tested for opens and shorts Impedance measurement - An impedance measurement report is not mandatory Packaging Packaging for the PCBs must meet the following requirements: • Finished PCBs must remain in panel • Finished PCBs must be packed in plastic bags that do not contain silicones or sulphur materials.
