BS24-U-IPEX 使用的是 一代 IPEX 天线座,结构尺寸如下:
天线推荐使用 FPC-IPEX 天线,参考如下:
IPEX 外接天线固定时,为确保无线性能的最优,建议天线部分和其他金属件的距离至少在 15mm 以上。
天线外围不要包裹金属件,以免影响天线辐射性能。建议天线区域的转接板镂空处理。
PCB 尺寸大小:16.3±0.35mm (W)×15.8±0.35mm (L) ×1.0±0.1mm (H)。
涂鸦出厂的可贴可插封装模组根据客户底板设计方案选择组装方式,底板设计为贴片封装时使用 SMT 贴片制程进行生产,如果底板设计为插件封装时使用波峰焊制程进行生产。模组产品拆开包装后建议在 24 小时内完成焊接,否则需放置在湿度不超过 10%RH 的干燥柜内,或重新进行真空包装并记录暴露时间,总暴露时间不超过 168 小时。
涂鸦出厂的模组存储条件如下:
防潮袋必须储存在温度 <40℃、湿度 <90%RH 的环境中。
干燥包装的产品,保质期为从包装密封之日起 12 个月的时间。
密封包装内装有湿度指示卡:
涂鸦出厂的模组当出现可能受潮的情况下需要进行烘烤:
烘烤参数如下:
在整个生产过程中,请对模组进行静电放电(ESD)保护。
为了确保产品合格率,建议使用 SPI 和 AOI 测试设备来监控锡膏印刷和贴装品质。
因产品内置晶体,一般情况下可采用普通清洁剂或超声波清洗。但某些情况下,超声波清洗机产生的振动可能导致晶体内部结构受损。如使用超声波清洗需提前进行验证,确保超声波清洗后不会损伤模组内部晶体。
尽量避免使用超声波焊接对产品进行安装或加工,这种加工方式可能导致模组内晶体振动过大,出现晶体失效不良。
请根据制程选择相应的焊接方式,SMT 参考回流焊接炉温曲线推荐,波峰焊制程参考波峰焊接炉温曲线推荐。设定炉温与实测炉温有一定差距,本文所示温度均为实测温度。
方式一:SMT 制程(SMT 回流焊接推荐炉温曲线)
请参考回流焊炉温曲线要求进行炉温设定,回流焊温度曲线如下图所示:
A:温度轴
B:时间轴
C:合金液相线温度区间为 217-220℃
D:升温斜率为 1-3℃/s
E:恒温时间为 60-120s,恒温温度区间为 150-200℃
F:液相线以上时间为 50-70s
G:峰值温度为 235-245℃
H:降温斜率为 1-4℃/s
以上推荐曲线以 SAC305 合金焊膏为例。其他合金焊膏请按焊膏规格书推荐炉温曲线设置。
方式二:波峰焊制程(波峰焊接炉温曲线)
请参考波峰焊接炉温建议进行炉温设定,峰值温度 260℃±5℃,波峰焊接温度曲线如下图所示:

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 installation. 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:
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. The OEM integrator is responsible for ensuring that the end-user has no manual instructions to remove or install the module.
Important Note
This radio module must not be installed to co-locate and operate simultaneously with other radios in the host system except by 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 intended destination. The firmware setting is not accessible to the end-user.
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 certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Separate approval is required for all other operating configurations including portable configurations with respect to Part 2.1093 and different antenna configurations.
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-BS24-U-IPEX. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-BS24-U-IPEX”.
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 transmitter or antenna.
As long as the 2 conditions above are met, further transmitter tests 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.
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.
