TYBT2 使用的 PCB 天线是 2.4G Wi-Fi 频段的板载天线。
为确保 RF 性能的最优化,建议模块天线部分和其他金属件距离至少在 15mm 以上。由于 TYBT2 的使用是通过 SMT 工艺,贴到主控板上配合其他元器件一起应用。那么 PCB 天线的摆放位置和摆放方式会直接影响 RF 性能。以下是我们推荐的摆放位置, 和不建议的摆放位置。
下图是 TYBT2 天线的各个摆放位置,推荐使用方案 1 和方案 2 的摆放位置,天线在板框外或天线附近挖空。性能和单独模块 RF 测试性能基本一致。
如果设计受限必须将 PCB 天线放在底板上,可以参考方案 3 的摆放方式,天线在板框内,但天线附近不覆铜和走线。但射频性能会有一些损失,差不多衰减 1-2dBm。
不建议使用方案 4 的摆放位置,天线在板框内,且天线下覆铜或走线。射频信号会明显的衰减。
备注:默认的模组外形尺寸公差为 ±0.35 mm,关键尺寸公差 ±0.1 mm。关键尺寸如果客户有明确要求,请沟通后在规格书中进行明确的标定。
涂鸦出厂的贴片封装模组建议使用 SMT 机器贴片,拆开包装后建议在 24 小时内完成焊接,如果拆封后未使用完建议放置在湿度不超过 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。
请根据回流焊曲线图进行温度设定,峰值温度 245℃,回流焊温度曲线如下图所示:

C:合金液相线温度:217-220℃
D:升温斜率:1-3℃/S
E:恒温时间:60-120S;恒温温度:150-200℃
F:液相线以上时间:50-70S
G:峰值温度:235-245℃

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 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 equipment complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This equipment should be installed and operated with minimum distance 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 simultaneously with other radio.
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 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 certification. 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/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.
The RF module is considered as a limited modular transmitter according to FCC rules.Even though the RF module get a FCC ID, the host product manufacturer can not use the FCC ID on the final product directly.In these circumstances, the host product manufacturer integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining the FCC authorization by a Class II permissive change application or a new application.
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
This product must not be disposed of as normal household waste, in accordance with 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.
