Antenna interference reduction

To ensure the optimal Wi-Fi performance, it is recommended that the antenna be at least 15 mm away from other metal parts.
To prevent adverse impact on the antenna radiation performance, avoid copper or traces within the antenna area on the PCB.

HPWSMS1 Module Datasheet

Production instructions

  • The stamp-hole module must be mounted by the SMT machine. After being unpacked, it must be soldered within 24 hours. Otherwise, it must be put into the drying cupboard where the RH is not greater than 10%, or it needs to be packaged under vacuum again and the exposure time needs to be recorded (the total exposure time cannot exceed 168 hours).

    • SMT equipment:
      • Mounter
      • SPI
      • Reflow soldering machine
      • Oven temperature tester
      • Automated optical inspection (AOI) equipment
    • Baking equipment:
      • Cabinet oven
      • Anti-static heat-resistant pallets
      • Anti-static heat-resistant gloves
  • Storage conditions for a delivered module are as follows:

    • 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.
    • The package contains a humidity indicator card (HIC).
      HPWSMS1 Module Datasheet
  • The module needs to be baked in the following cases:

    • Vacuum packing bag was found to be damaged before being unpacked.
    • There is no humidity indicator card (HIC) in the vacuum packing bag.
    • After being unpacked, 10% and above circles on the HIC become pink.
    • The total exposure time has been more than 168 hours since unpacking.
    • More than 12 months have passed since the sealing date of the bag.
  • Baking settings:

    • Temperature: 60°C and ≤ 5%RH for reelizing and 125°C and ≤5%RH for palletizing (please use heat-resistant pallet rather than plastic pallet)
    • Time: 48 hours for reelizing and 12 hours for palletizing
    • Alarm temperature: 65°C for reelizing and 135°C for palletizing
    • Production ready temperature after natural cooling: < 36°C
    • The number of drying times: 1
    • Re-baking condition: If a module remains unused for 168 hours after being unpacked, it must be baked again.

      Important: If this batch of modules is not baked within 168 hours, do not use the wave soldering to solder them. Because these modules are 3-level moisture-sensitive components, they are very likely to get damp when exposed outside. In this case, if they are soldered at high temperatures, it may result in component failure or poor soldering.

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

  • To guarantee the passing rate, it is recommended that you use the SPI and AOI to monitor the quality of solder paste printing and mounting.

Recommended oven temperature curve

Perform mounting with the SMT based on the following reflow oven temperature curve. The highest temperature is 245°C. The reflow temperature curve is as below:

HPWSMS1 Module Datasheet

  • A: Temperature axis

  • B: Time axis

  • C: Liquidus temperature: 217 to 220°C

  • D: Ramp-up slope: 1 to 3°C/s

  • E: Duration of constant temperature: 60 to 120s; the range of constant temperature: 150 to 200°C

  • F: Duration above the liquidus: 50 to 70s

  • G: Peak temperature: 235 to 245°C

  • H: Ramp-down slope: 1 to 4°C/s

    Note: The above curve is just an example of the solder paste SAC305. For more details about other solder pastes, please refer to Recommended oven temperature curve in the 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 operating simultaneously with other radios in the host system except 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 by 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-HPWSMS1. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-HPWSMS1”.

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.
