只有 PCB 板载天线接入方式。
在 Wi-Fi 模组上使用 PCB 板载天线时,为确保 Wi-Fi 性能的最优化,建议模组天线部分和其他金属件距离至少在 15mm 以上。
用户 PCB 板在天线区域勿走线甚至覆铜,以免影响天线性能。布局要点是:确保印制天线正下方或者正上方没有基板介质;确保印制天线的周围远离金属铜皮,这样可以最大程度上保证天线的辐射效果。

TYWE2L PCB 封装图
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。
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。
