Antenna information

Antenna type

The T5-E1 module uses an onboard PCB antenna.

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. According to the antenna shape of the T5-E1 module, you can choose Position 3 or Position 4 (optimal) when using the module.

Production instructions

  1. Package the module with the SMT if Tuya’s module is designed to be SMT-packaged. After being unpacked, the module must be soldered within 24 hours. Otherwise, it needs to be put into a drying cupboard with a relative humidity level no greater than 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
      • AOI
    • Instruments or devices required for the baking process:
      • Cabinet oven
      • Electro-static discharge (ESD) protection and heat-resistant trays
      • ESD protection and heat-resistant gloves
  2. 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 indicator card (HIC) is put in the sealed package.

      T5-E1 Module Datasheet
  3. 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.
  4. 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 plastic containers).
    • 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.
  5. In the whole production process, take electrostatic discharge (ESD) protective measures.

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

Recommended oven temperature curve

Set the temperature according to the following temperature curve of reflow soldering. The peak temperature is 245°C.

  • A: temperature axis

  • B: time axis

  • C: alloy liquidus temperature from 217°C to 220°C

  • D: ramp-up slope from 1°C/s to 3°C/s

  • E: keep a constant temperature from 150°C to 200°C for a time period from 60s to 120s

  • F: temperature above liquidus temperature for 50s to 70s

  • G: peak temperature from 235°C to 245°C

  • H: ramp-down slope from 1°C/s to 4°C/s

    The curve above is based on solder paste SAC305. For more information about other solder pastes, see the recommended oven temperature curve in the specified solder paste specifications.

Appendix: Statement

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This device has been tested and found to comply with the limits for a Class B digital device, according to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This device generates, uses, and can radiate radio frequency energy and, if not installed and used following the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

If this device does cause harmful interference to radio or television reception, which can be determined by turning the device 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 device and receiver.
  • Connect the device 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.

Radiation Exposure Statement

This device complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This device should be installed and operated with a minimum distance of 20cm between the radiator and your body.

Important Note

This radio module must not be installed to co-locate and operate simultaneously with other radios in the host system except by following FCC multi-transmitter product procedures. Additional testing and device authorization may be required to operate simultaneously with other radios.

The availability of some specific channels and/or operational frequency bands are country-dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible to the end-user.

The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

The end-user manual shall include all required regulatory information/warnings as shown in this manual, including “This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body”.

This device has got an FCC ID: 2ANDL-T5-E1. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-T5-E1”.

This device is intended only for OEM integrators under the following conditions:

The antenna must be installed such that 20cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.

As long as the 2 conditions above are met, further transmitter tests will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.
