14 / 22 6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS The following is the diagram of the packaging of the PCB of CR2S:
6.3 Production instructions 1. For the in-line module developed by Tuya, wave soldering equipment is most preferred and manual soldering is less preferred. After being unpacked, the module must be soldered within 24 hours; otherwise, it needs to be packaged again under vacuum. 2. Soldering equipment and materials:
Wave soldering equipment:
Wave soldering xture Constant-temperature soldering iron 15 / 22 6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS Tin bar, tin wire, and ux Oven temperature tester Baking equipment:
Cabinet oven Anti-static heat-resistant trays Anti-static heat-resistant gloves 3. The module developed by Tuya needs to be baked in the following cases:
Vacuum packaging bag was damaged before unpacking. There is no humidity indicator card (HIC) in the vacuum packaging bag. After unpacking, 30% and above circles on the HIC become pink. Production is not completed within 72 hours after unpacking. More than 6 months have passed since the sealing date of the bag. 4. Baking settings:
Baking temperature: reel packing 655, pallet packing 1255 Baking time: reel packing 48 hours, pallet packing 12 hours Alarm temperature: reel packing 70, pallet packing 130 Production ready temperature after natural cooling: < 36C The number of drying times: 1 Rebaking condition: The module is not soldered within 72 hours after bak-
ing. sures. 5. Do not use wave soldering to process modules that have been unpacked for more than 3 months, because electroless nickel/immersion gold (ENIG) is used for PCBs and they will seriously be oxidized for more than 3 months. The wave soldering is very likely to cause pseudo and missing soldering. Tuya is not liable for such problems and consequences. 6. In the production process, take electrostatic discharge (ESD) protective mea-
7. To ensure the quality of products, you should pay attention to the amount of soldering ux, the wave peak, whether the content of the tin slag and copper in the wave soldering tank exceeds the standards, whether the window and thickness of the wave soldering xture are appropriate, and whether the wave soldering oven temperature curve is reasonable. 16 / 22 6 PACKAGING INFORMATION AND PRODUCTION INSTRUCTIONS 6.4 Recommended oven temperature curve and temperature For oven temperature setting, refer to oven temperatures for wave soldering. The peak temperature is 2605. The wave soldering temperature curve is as be-

The EUT was place on a turn table which is 1.5m above ground plane for above 1GHz and 0.8m above ground for below 1GHz at 3 meter chamber room for test. The table was rotated 360 degrees to determine the position of the highest radiation. 2. The EUT was set 3 meters away from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 3. The height of antenna is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. 4. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. 5. Use the following spectrum analyzer settings According to C63.10:
For Below 1GHz Use the following spectrum analyzer settings:
Span = wide enough to capture the peak level of the in-band emission and all spurious RBW = 100 kHz to 120 kHz, VBWRBW for peak measurement, Sweep = auto, Detector function = peak, Trace = max hold. For Peak unwanted emissions Above 1GHz:
Span = wide enough to capture the peak level of the in-band emission and all spurious RBW = 1MHz, VBWRBW for peak measurement, Sweep = auto, Detector function =
peak, Trace = max hold. Procedures for average unwanted emissions measurements above 1000 MHz a) RBW = 1MHz. b) VBW [3 RBW]. c) Detector = RMS (power averaging), if [span / (# of points in sweep)] RBW / 2. Satisfying this condition can require increasing the number of points in the sweep or reducing the span. If the condition is not satisfied, then the detector mode shall be set to peak. d) Averaging type = power (i.e., rms) (As an alternative, the detector and averaging type may be set for linear voltage averaging. Some instruments require linear display mode to use linear voltage averaging. Log or dB averaging shall not be used.) e) Sweep time = auto. f) Perform a trace average of at least 100 traces if the transmission is continuous. If the transmission is not continuous, then the number of traces shall be increased by a factor of 1 / D, where D is the duty cycle. For example, with 50% duty cycle, at least 200 traces shall be averaged. (If a specific emission is demonstrated to be continuousi.e., 100%
duty cyclethen rather than turning ON and OFF with the transmit cycle, at least 100 traces shall be averaged.) g) If tests are performed with the EUT transmitting at a duty cycle less than 98%, then a correction factor shall be added to the measurement results prior to comparing with the emission limit, to compute the emission level that would have been measured had the test been performed at 100% duty cycle. The correction factor is computed as follows:

For example, if the transmit duty cycle was 50%, then 3 dB shall be added to the measured emission levels. 2) If linear voltage averaging mode was used in the preceding step e), then the correction factor is [20 log (1 / D)], where D is the duty cycle. For example, if the transmit duty cycle was 50%, then 6 dB shall be added to the measured emission levels. 3) If a specific emission is demonstrated to be continuous (100% duty cycle) rather than turning ON and OFF with the transmit cycle, then no duty cycle correction is required for that emission. Limit The radio emission outside the operating frequency band shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power. Radiated emissions which fall in the restricted bands, as defined in section15.205 and RSS-GEN 8.10 must comply with the radiated emission limits specified in section 15.209.
