11 / 21 BT2S Module Datasheet 6 ANTENNA INFORMATION 6 Antenna Information 6.1 Antenna Type BT2S uses an onboard PCB antenna. 6.2 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 perfor-

mance. Because BT2S is inserted to the PCB, sucient space needs to be reserved for the antenna. 12 / 21 7 Packaging Information and Production Instructions 7 Packaging Information and Production Instructions 7.1 Mechanical Dimensions Figure 3: BT2S .png Note: The default dimensional tolerance is 0.35 mm, and the tolerance for some measurements is 0.1 mm. If a customer has other requirements, clearly specify them in the datasheet after communication. 7.2 Production Instructions 1. Use an SMT placement machine to mount components to the stamp hole mod-

ule that Tuya produces within 24 hours after the module is unpacked and the 13 / 21 7 Packaging Information and Production Instructions rmware is burned. If not, vacuum pack the module again. Bake the module before mounting components to the module. A. SMT placement equipment a) Reow soldering machine b) Automated optical inspection (AOI) equipment c) Nozzle with a 6 mm to 8 mm diameter B. Baking equipment d) Cabinet oven e) Anti-static heat-resistant trays f) Anti-static heat-resistant gloves 2. Storage conditions for a delivered module are as follows:

1 A. The moisture - proof bag is placed in an environment where the temperature is below 30 C and the relative humidity is lower than 70%. 2 B. The shelf life of a dry - packaged product is six months from the date when the product is packaged and sealed . 3 C. The package contains a humidity indicator card (HIC). Figure 4: image.png package 3. Bake a module based on HIC status as follows when you unpack the module A. If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecu-

tive hours. B. If the 30% circle is pink, bake the module for 4 consecutive hours. C. If the 30% and 40% circles are pink, bake the module for 6 consecutive 14 / 21 7 Packaging Information and Production Instructions hours. D. If the 30%, 40%, and 50% circles are pink, bake the module for 12 consecu-

tive hours. 4. Baking settings:

A. Baking temperature: 1255C B. Alarm temperature: 130C C. SMT placement ready temperature after natural cooling: < 36C D. Number of drying times: 1 E. Rebaking condition: The module is not soldered within 12 hours after baking. 5. Do not use SMT to process modules that have 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. Tuya is not liable for such problems and consequences. 6. Before SMT placement, take electrostatic discharge (ESD) protective measures. 7. To reduce the reow defect rate, draw 10% of the products for visual inspection and AOI before rst 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. 7.3 Recommended Oven Temperature Curve Please refer to the recommended temperature of wave soldering furnace for setting the furnace temperature. The peak temperature is 2605. The curve of wave soldering temperature is shown in the following gure:

sponsible for compliance could void the users authority to operate this equipment. This device complies with Part 15 of the FCC Rules.Operation is subject to the fol-

lowing 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 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 o and on, the user is encour-

aged 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 equipment and receiver. Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Radiation Exposure Statement This equip-

ment complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This equipment should be installed and operated with minimum dis-

tance 20cm between the radiator and your body. Important Note This radio module must not installed to co-locate and operating simultaneously with other radios in host system except in accordance with FCC multi-transmitter product procedures. Additional testing and equipment authorization may be required to operating simul-

taneously with other radio. The availability of some specic channels and/or opera-

tional frequency bands are country dependent and are rmware programmed at the factory to match the intended destination. The rmware setting is not accessible by the end user. The host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certication. The nal 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/warning 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 have got a FCC ID2ANDL-BT2S.The nal 20 / 21 BT2S Module Datasheet 9 APPENDIX: STATEMENT end product must be labeled in a visible area with the following: Contains Transmit-

ter Module FCC ID: 2ANDL-BT2S This device is intended only for OEM integrators under the following conditions: 1)The antenna must be installed such that 20cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compli-

ance requirements required with this module installed.
