6. Design Recommendations
a) Keep out enough area for the chip antenna.
b) Avoid any routing under antenna area as shown in the below image.
c) Better to place the module away from High frequency circuitry like other RF, and large
components or metallic objects.
d) All GND pins must be well grounded.
e) The area around the module should be free of any ground planes, power planes, trace
routings or metal for 6 mm from the module antenna position in all directions.
f) Better not to route any traces underneath the module.
g) The WIM1481 series modules contain highly sensitive electronic circuitry and are
Electrostatic Sensitive Devices (ESD). Handling the WIM series modules without proper
ESD protection may destroy or damage them permanently.

9. Soldering Information
Leadfree reflow soldering
Do not exceed peak temperature (Tp) of 242°C. Time at maximum temperature is 27 seconds.
After reflow soldering, optical inspection of the module is recommended to verify proper
alignment. Hand soldering is also possible.
Cleaning
In general, cleaning the populated modules is strongly discouraged. Residuals under the
module cannot be easily removed with any cleaning process.
1. Cleaning with water can lead to capillary effects where water is absorbed into the gap between
the host board and the module. The combination of soldering flux residuals and encapsulated
water could lead to short circuits between neighboring pads. Water could also damage any
stickers or labels.
2. Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into
the RF shield, which is not accessible for post-washing inspection. The solvent could also
damage any stickers or labels.

12. Precautions
While integrating module, make sure all the pads are soldered properly.
Please use a voltage regulator if the power supply is above the max ratings.
For best wireless signals, please avoid packing the antenna close to metal parts or cases.
Stresses above the listed maximum ratings may cause permanent damage to the device.

harmful interference to radio or television reception, which can be determined by turn ing the
equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help important announcement
