生产指南

  1. 涂鸦出厂的邮票口封装模组必须由SMT机器贴片,并且拆开包装烧录固件后必须24小时内完成贴片,否则要重新抽真空包装,贴片前要对模组进行烘烤。

    • SMT贴片所需仪器或设备:
      • 回流焊贴片机
      • AOI检测仪
      • 口径6-8mm吸嘴
    • 烘烤所需仪器或设备:
      • 柜式烘烤箱
      • 防静电耐高温托盘
      • 防静电耐高温手套
  2. 涂鸦出厂的模组存储条件如下:

    • 防潮袋必须储存在温度<30℃、湿度<70%RH的环境中。
    • 干燥包装的产品,保质期为从包装密封之日起6个月的时间。
    • 密封包装内装有湿度指示卡:
      WBLC5 模组规格书
  3. 涂鸦出厂的模组需要烘烤,湿度指示卡及烘烤的几种情况如下所述:

    • 拆封时如果湿度指示卡读值30%、40%、50%色环均为蓝色,需要对模组进行持续烘烤2小时
    • 拆封时如果湿度指示卡读取到30%色环变为粉色,需要对模组进行持续烘烤4小时
    • 拆封时如果湿度指示卡读取到30%、40%色环变为粉色,需要对模组进行持续烘烤6小时
    • 拆封时如果湿度指示卡读取到30%、40%、50%色环变为粉色,需要对模组进行持续烘烤12小时
  4. 烘烤参数如下:

    • 烘烤温度:125±5℃
    • 报警温度设定:130℃
    • 自然条件下冷却<36℃后,即可进行SMT贴片
    • 干燥次数:1次
    • 若烘烤后超过12小时没有焊接,请再次进行烘烤
  5. 如果拆封时间超过3个月,禁止使用SMT工艺焊接此批次模组,因为此PCB为沉金工艺,超过3个月后焊盘氧化严重,SMT贴片时极有可能导致虚焊、漏焊,由此带来的种种问题我司不承担相应责任;

  6. SMT贴片前,请对模组进行ESD(静电放电、静电释放)保护;

  7. 为了确保回流焊合格率,首次贴片请抽取10%产品进行目测、AOI检测,以确保炉温控制、器件吸附方式、摆放方式的合理性;之后的批量生产建议每小时抽取5-10片进行目测、AOI检测。

推荐炉温曲线

请根据回流焊曲线图进行直插上件,峰值温度245℃,回流焊温度曲线如下图所示:

Appendix: Statement

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.

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 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 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 equipment and receiver.
  • Connect the equipment 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 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.
