5 Antenna
5.1 Antenna type
This product uses an onboard PCB antenna or IPEX.
5.2 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.
7 Production instructions
- Use an SMT placement machine to mount components to the stamp hole module that DUSUN produces within 24 hours after the module is unpacked and the firmware is burned. If not, vacuum packs the module again. Bake the module 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
2.Storage conditions for a delivered module are as follows:
- The moisture-proof bag is placed in an environment where the temperature is below 30℃ and the relative humidity is lower than 70%.
- The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed.
- The package contains a humidity indicator card (HIC).
3.Bake a module based on HIC status as follows when you unpack the module package:
- If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecutive hours.
- 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 consecutive hours.
- 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.
5.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 pads are exposed to the air for over three months, they will be oxidized severely and dry joints or solder skips may occur. Roombanker is not liable for such problems and consequences.
6.Before SMT placement, take electrostatic discharge (ESD) protective measures.
7.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 temperature and component placement method. Draw 5 to 10 modules every hour from subsequent batches for visual inspection and AOI.
7.1 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.
