Introduction
This document specifies the details for a WiFi 802.11a/b/g/n/ac with BT4.1
RFSOM module called with Honeywell Part No.
50145732-001
RFSOM WBT, SOM MODULE, WIFI 802.11AC BT 4.2
uzon Module will use WM-BAC-AT-39 USI SiP module with Qualcomm
QCA6174A chip set which includes LNA, switch, and internal power amplifier
(iPA) for small form factor and optimum performance. All filters and diplexers
will be included in the module to ensure maximum power flatness and optimum
VSWR. The module will perform with all legacy hardware having data rates as low as
1Mbps. This chipset also supports concurrent operation of Bluetooth (Version 4.1) for
wireless connectivity during browsing or other device applications. Along with both
standard and high speed (HS) Bluetooth data rates, Bluetooth low energy modes are
also supported. Hardware WAPI acceleration engine, AES, TKIP, WPA and WPA2 are
supported to provide the latest security requirement on your network.
For placing the SOMAT39 onto the carrier board, the part number to be used is
50145748-001. The footprint details are available in
Global Library for using on the carrier board.
SOMAT39 is meant to be used inside Honeywell only. It
is not meant or designed to be sold independently outside Honeywell

RF Layout, Soldering Guidelines
RF Layout & Design Guidelines
I. Do not run antenna cables directly above or directly below the radio.
II. Do not run any high speed digital lines below the radio.
III. For applications using only 1X1, the second antenna port i.e RF_ANT1
to be terminated with a 50 ohm resistor close to the pin of SOMAT39.
IV. Isolate VDD2 & VDD3 (pin no 36 & 37) with a ferrite bead
(BLM15AG100SN1D) and decaps of 22uF and 0.1uF to be placed very
close to the pins.
V. 10uF and 0.1uF to be used at VDD1 i.e pin no 23 and the input power
supply which are to be placed very close to the pins.
VI. A 100K pull down resistors to be used for BT_DEV_WAKE, WL_EN
and BT_EN close to the pins of RF SOM.
VII. A series R (10E) and shunt capacitor (22pf) is recommended to reduce the
SDIO clock noise going to the input of SOMAT39 pin (pin no 43).
VIII. Use proper electro-static-discharge (ESD) procedures when installing the
SOMAT39 module.
Chapter

14
Soldering Guidelines
SOMAT39 is compatible with industrial standard reflow profile for Pb-free solders. The
reflow profile selection to be done based on the thermal mass of the entire populated
PCB, heat transfer efficiency of the oven and solder paste used.
I. Refer to technical documentations of solder paste for profile
configurations.
II. Avoid using more than one reflow cycle.
III. Aperture size of the stencil should be 1:1 with the pad size.
IV. For further recommendation, please refer to the JEDEC/IPC J-STD-020,
IPC-SM-782 and IPC 7351 guidelines.
Below is the overview of recommended Re-flow:
(1) Solder paste alloy: SAC305 (Sn96.5/Ag3.0/Cu0.5) (Lead Free solder paste.)
(2) A-B. Temp.: 150~200℃; soak time:60~120sec. (Base on Flux type, reference only)
(3) C. Peak temp: <245℃
(4) D. Time above 217 ℃: 40~90sec. (Base on SAC305)
(5) Suggestion: Optimal cooling rate is <1℃/sec. from peak to 217 ℃.
(6) Nine heater zones at least for Reflow equipment.
(7) Nitrogen usage is recommended and be controlled the value less than 1500 ppm.
Note: Need to inspect solder joint by X-ray post reflow
