Preheating zone: The temperature is from 40 ° C to 150 ° C, the temperature rise rate is controlled at about 2 ° C /s, and the temperature zone time is 60 ~ 150s.
Average temperature zone: the temperature is 150 ~ 200, steadily and slowly rising, the temperature rise

rate is less than 1/s, and the time in the region is controlled at 60 ~ 120s (Note: the region must be slowly

heated, otherwise it is easy to lead to bad welding).

Reflux zone: temperature from 217 ~ Tmax ~ 217, the whole interval time is controlled at 60 ~ 90s.

Cooling zone: The temperature is from Tmax to 180, and the maximum temperature drop rate can not exceed 4/s.
The temperature from room temperature 25 to 250 should not exceed 6 minutes.

The reflow curve is recommended only. The client needs to adjust it according to the actual production situation.
The target reflux time is 60 to 90s. For some boards with large heat capacity that cannot meet the time
requirements, the reflux time can be set relax to 120s. Package body temperature standard refer to IPC/JEDEC J-STD-020D standard, package body temperature

The device welding ends (welding balls, pins) and external heat sinks are not included in t he volume calculation. Reflow welding process curve measurement wed method:

JEP140 recommendation: For devices with small thickness, the thermocouple is directly attached to the surface of the device when measuring the temperature of the package, and for devices with large thickness, the thermocouple is drilled into the surface of the device for measurement. Due to the requirements of quantifying the thickness of the device, it is recommended to use all the holes in the surface of the package buried in the thermocouple type (especially thin devices, except drilling is not possible).

FCC Statement 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user’ s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursua nt to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful inte rference in a residential installation. This equipment generates uses and can radiate radio frequency energy a nd, if not installed and used in accordance with the instructions, may cause harmful interference to radio com munications. 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 turn ing the equipment 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 receivingantenna. – 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 important announcement Important Note: Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada. This device is intended only for OEM integrators under the following conditions: 1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2. The transmitter module may not be co-located with any other transmitter or antenna, 3. For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band
by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel 1-11) As long as the three conditions above are met, further transmitter testing 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.
Important Note: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling The final end product must be labeled in a visible area with the following” Contains FCC ID: 2AXX8-E901-NI-WS”
Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
