生产指南

• 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。

  • （SMT 制程）SMT 贴片所需仪器或设备：
    • 贴片机
    • SPI
    • 回流焊
    • 炉温测试仪
    • AOI
  • （波峰焊制程）波峰焊所需的仪器或设备：
    • 波峰焊设备
    • 波峰焊接治具
    • 恒温烙铁
    • 锡条、锡丝、助焊剂
    • 炉温测试仪
  • 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

• 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：

  • 拆封前发现真空包装袋破损。
  • 拆封后发现包装袋内没有湿度指示卡。
  • 拆封后如果湿度指示卡读取到 10% 及以上色环变为粉色。
  • 拆封后总暴露时间超过 168 小时。
  • 从首次密封包装之日起超过 12 个月。

• 烘烤参数如下：

  • 烘烤温度：卷盘包装 40℃，湿度小于等于 5%RH。托盘包装 125℃，小于等于 5%RH（耐高温托盘非吸塑盒拖盘）
  • 烘烤时间：卷盘包装 168 小时，托盘包装 12 小时。
  • 报警温度设定：卷盘包装 50℃，托盘包装 135℃。
  • 自然条件下冷却到 36℃ 以下后，即可进行生产。
  • 若烘烤后暴露时间大于 168 小时没有使用完，请再次进行烘烤。
  • 如果暴露时间超过 168 小时未经过烘烤，不建议使用回流焊或波峰焊接工艺焊接此批次模组。因模组为 3 级湿敏器件超过允许的暴露时间产品可能受潮，进行高温焊接时可能会导致器件失效或焊接不良

• 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。

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.

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