If metal materials wrap around the antenna, the wireless signal will be greatly attenuated, thereby deteriorating the RF perfor-

mance. When designing the finished product, please leave enough space for the antenna. 13 / 26 6 Packaging information and production instructions 6 Packaging information and production instructions 6.1 Mechanical dimensions and dimensions of the back of the pad 14 / 26 6 Packaging information and production instructions 15 / 26 6 Packaging information and production instructions Recommended PCB footprint 16 / 26 6 Packaging information and production instructions 17 / 26 6 Packaging information and production instructions The default outline dimension tolerance is 0.35 mm, and the critical dimension If you have specific requirements on dimensions, specify tolerance is 0.1 mm. them clearly in the datasheet after communication. 6.2 Production instructions 1. For the Tuya in-line module, wave soldering is most preferred and manual sol-

dering is less preferred. After being unpacked, the module 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 record the exposure time (the total exposure time cannot exceed 168 hours). 2. Wave soldering devices and materials:

Wave soldering equipment Wave soldering fixture Constant-temperature soldering iron Tin bar, tin wire, and flux Thermal profiler 3. Baking devices:

Cabinet oven Anti-electrostatic and heat-resistant trays Anti-electrostatic and heat-resistant gloves 4. The module needs to be baked in the following cases:

The packaging bag is damaged before unpacking. There is no humidity indicator card (HIC) in the packaging bag. After unpacking, circles of 10% and above on the HIC become pink. The total exposure time has lasted for over 168 hours since unpacking. More than 12 months have passed since the sealing of the bag. 5. Baking settings:

Temperature: 60C and 5% RH for reel package and 125C and 5%

RH for tray package (please use the heat-resistant tray rather than plastic container) Time: 48 hours for reel package and 12 hours for tray package Alarm temperature: 65C for reel package and 135C for tray package 18 / 26 6 Packaging information and production instructions Production-ready temperature after natural cooling: < 36C Re-baking situation: If a module remains unused for over 168 hours after being baked, it needs to be baked again. If a batch of modules is not baked within 168 hours, do not use the wave soldering to solder them. Because these modules are Level-3 moisture-

sensitive devices, they are very likely to get damp when exposed beyond the allowable time. In this case, if they are soldered at high temperatures, it may result in device failure or poor soldering. 6. In the whole production process, take electrostatic discharge (ESD) protective measures. 7. To guarantee the quality of products, you must pay attention to the following items: The amount of soldering flux, the height of the wave peak, whether the tin slag and copper content in the wave soldering tank exceed standards, whether the window and thickness of the wave soldering fixture are appropri-

ate, and whether the wave soldering oven temperature curve is appropriate. 6.3 Recommended oven temperature curve and temperature Set oven temperatures according to the following temperature curve of wave sol-

dering. The peak temperature is 260C5C. 19 / 26 6 Packaging information and production instructions

The moisture-proof bag is placed in an environment where the temperature is below 40C 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. There is a humidity indicator card (HIC) in the packaging bag. 21 / 26 6 Packaging information and production instructions 22 / 26 7 MOQ and packaging information 7 MOQ and packaging information Product model MOQ (pcs) Packing method Modules per reel Reels per carton BP3L 3600 Tape reel 900 4 23 / 26 8 Appendix: Statement 8 Appendix: Statement FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the users 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 instal-

lation. 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 in-

tended destination. The firmware setting is not accessible by the end-user. 24 / 26 8 Appendix: Statement 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 certi-

fication. 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-BP3L. The end product must be labelled in a visible area with the following: Contains Transmitter Module FCC ID: 2ANDL-BP3L

. 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 trans-

mitter or antenna. As long as the 2 conditions above are met, further transmitter tests will not be re-

quired. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Declaration of Conformity European Notice Hereby, Hangzhou Tuya Information Technology Co., Ltd declares that this module product is in compliance with essential requirements and other relevant provisions of Directive 2014/53/EU, 2011/65/EU. A copy of the Declaration of conformity can be found at https://www.tuya.com. 25 / 26 8 Appendix: Statement This product must not be disposed of as normal household waste, in accordance with the EU directive for waste electrical and electronic equipment (WEEE-2012/19/EU). Instead, it should be disposed of by returning it to the point of sale, or to a municipal recycling collection point.
