Antenna information

Antenna type

Only PCB antenna applies.

Antenna interference reduction

When a PCB antenna is used on a Wi-Fi module, we recommend that the module antenna is at least 15 mm away from other metal components. This can optimize the Wi-Fi performance.

Make sure that the enclosure surrounding the antenna is not traced or filled with copper. Otherwise, the RF performance might be degraded.

Layout principles: No substrate medium exists directly below or above the PCB antenna. The PCB antenna is away from the copper sheet. This can maximize the radiation effect of the antenna.

Refer to the mechanical dimensions below for the module’s PCB onboard antenna area.

Production instructions

• For the modules that can be packaged with the surface-mount technology (SMT) or in in-line form, you can select either of them according to the PCB design solutions of customers. If a PCB is designed to be SMT-packaged, package the module with the SMT. If a PCB is designed to use an in-line package, use wave soldering. Complete soldering within 24 hours after the module is unpacked. Otherwise, we recommend that you place the module in a drying cupboard with a relative humidity level below 10%, or pack the module in vacuum again. Then, record the packing time and duration of exposure. The total exposure time cannot exceed 168 hours.

  • Instruments or devices required for the SMT process:
    • Surface mount system
    • SPI
    • Reflow soldering machine
    • Thermal profiler
    • Automated optical inspection (AOI) device
  • Instruments or devices required for the wave soldering process:
    • Wave soldering device
    • Wave soldering fixture
    • Constant-temperature soldering iron
    • Tin bar, tin wire, and flux
    • Thermal profiler
  • Instruments or devices required for the baking process:
    • Cabinet oven
    • Electrostatic discharge (ESD) protection and heat-resistant trays
    • ESD protection and heat-resistant gloves

• A delivered module must meet the following storage requirements:

  • The moisture-proof bag must be placed in an environment where the temperature is below 40°C and the relative humidity is lower than 90%.

  • The shelf life of a dry-packaged product is 12 months from the date when the product is packaged and sealed.

  • A humidity indication card (HIC) is put in the sealed package.

    

• The module needs to be baked in the following cases:

  • The vacuum packaging bag is damaged before unpacking.
  • After unpacking, no HIC is found in the packaging bag.
  • After unpacking, the HIC indicates a humidity level of 10% or higher. In this case, the circle turns pink on the HIC.
  • The total exposure time has lasted for over 168 hours since unpacking.
  • More than 12 months have passed since the first sealing of the bag.

• The baking parameter settings are described below:

  • Baking temperature: 40°C for reel packaging with relative humidity ≤ 5%. And 125°C for tray packaging with relative humidity ≤ 5% (use a heat-resistant tray, rather than a plastic container).
  • Baking time: 168 hours for reel packaging and 12 hours for tray packaging.
  • Temperature for triggering an alert: 50°C for reel packaging and 135°C for tray packaging.
  • Production can begin after a module has cooled down to below 36°C under natural conditions.
  • If a module remains unused for over 168 hours after being baked, it needs to be baked again.
  • If a batch of modules is not baked after exposure for more than 168 hours, do not use wave soldering to solder them. Because these modules are level-3 moisture-sensitive devices, they are very likely to get damp when exposed beyond the allowable time. In this case, if they are soldered at high temperatures, device failure or poor soldering performance might occur.

• In the whole production process, take electrostatic discharge (ESD) protective measures.

• To guarantee the pass rate, we recommend that you use the SPI and AOI to monitor the quality of solder paste printing and mounting.

Appendix: Statement

Important Notice to OEM integrators

1. This module is limited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part
   15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module’s intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint with the transmitter(s) rule(s).
   The Grantee will provide guidance to the host manufacturer for Part 15 B requirements if needed.

Important Note

Notice that any deviation(s) from the defined parameters of the antenna trace, as described by the
instructions, require that the host product manufacturer must notify to Tuya that they wish to change the antenna trace design. In this case, a Class II permissive change application is required to be filed by the TUYA, or the host manufacturer can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application.

End Product Labeling

When the module is installed in the host device, the FCC label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re-moved. If not, a second label must be placed on the outside of the final device that contains the following text: “Contains FCC ID: 2ANDL-T7U” .
The FCC ID can be used only when all FCC compliance requirements are met.
