Antenna

Antenna type
This product uses IPEX interface connect to external antenna such as stick antenna.

Antenna interference reduction
To ensure optimal RF performance, it is recommended that the antenna be at least 15 mm away from other metal parts. If metal materials are wrapped around the antenna, the wireless signals will be reduced greatly, deteriorating the RF performance.

Production instructions

Use an SMT placement machine to mount components to the stamp holemodule that DUSUN produces within 24 hours after the module is unpackedand the firmware is burned. If not, vacuum packs the module again. Bake themodule before mounting components to the module.

• SMT placement equipment:
  • Reflow soldering machine
  • Automated optical inspection (AOI) equipment
  • Nozzle with a 6 mm to 8 mm diameter
• Baking equipment:
  • Cabinet oven
  • Anti-static heat-resistant trays
  • Anti-static heat-resistant gloves

Storage conditions for a delivered module are as follows:

• The moisture-proof bag is placed in an environment where the temperature isbelow 30℃ and the relative humidity is lower than 70%.
• The shelf life of a dry-packaged product is six months from the date when theproduct is packaged and sealed.
• The package contains a humidity indicator card (HIC).

Bake a module based on HIC status as follows when you unpack the modulepackage:

• If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecutivehours.
• If the 30% circle is pink, bake the module for 4 consecutive hours.
• If the 30% and 40% circles are pink, bake the module for 6 consecutive hours.
• If the 30%, 40%, and 50% circles are pink, bake the module for 12 consecutivehours.

Baking settings:

• Baking temperature: 125±5℃

• Alarm temperature: 130℃
  SMT placement ready temperature after natural cooling: < 36℃

• Number of drying times: 1

• Rebaking condition: The module is not soldered within 12 hours after baking.

Do not use SMT to process modules that have been unpacked for over three months. Electroless nickel immersion gold (ENIG) is used for the PCBs. If the solder padsare exposed to the air for over three months, they will be oxidized severely anddry joints or solder skips may occur. Roombanker is not liable for such problems and consequences. Before SMT placement, take electrostatic discharge (ESD) protective measures. To reduce the reflow defect rate, draw 10% of the products for visual inspection and AOI before first SMT placement to determine a proper oven temperatureand component placement method. Draw 5 to 10 modules every hour from subsequent batches for visual inspection and AOI.

Recommended oven temperature curve
Perform SMT placement based on the following reflow oven temperature curve. The highest temperature is 245℃. Based on the IPC/JEDEC standard, perform reflow soldering on a module at most twice.

Note:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with 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 equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more ofthe 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.
