生产指南

  1. 涂鸦出厂的直插式模组建议优先使用波峰焊接设备焊接,在无法使用波峰焊接设备焊接时才使用手工焊接,拆开包装后必须在24小时内完成焊接,否则要重新进行真空包装。
  2. 焊接所需设备和材料:
    a) 波峰焊设备
    b) 波峰焊接治具
    c) 恒温烙铁
    d) 锡条、锡丝、助焊剂
    e) 炉温测试仪
    A. 烘烤所需仪器或设备:
    a) 柜式烘烤箱;
    b) 防静电耐高温托盘;
    c) 防静电耐高温手套;
  3. 涂鸦出厂的模块当出现可能受潮的情况下需要进行烘烤:
    A. 拆封前发现真空包装袋破损
    B. 拆封后发现包装袋内没有湿度指示卡;
    C. 拆封后如果湿度指示卡读取到30%及以上色环变为粉色
    D. 拆封后72小时内没有生产完成
    E. 从首次密封包装之日起超过6个月
  4. 烘烤参数如下:
    A. 烘烤温度:卷盘包装65±5℃;托盘包装125±5℃;
    B. 烘烤时间:卷盘包装48小时;托盘包装12小时;
    C. 报警温度设定:卷盘包装70℃;托盘包装130℃;
    D. 自然条件下冷却<36℃后,即可进行生产;
    E. 烘烤次数:1次;
    F. 若烘烤后72小时内没有使用完,请再次进行烘烤;
  5. 如果拆封时间超过3个月,禁止使用波峰焊接工艺焊接此批次模块,因为模组PCB为沉金工艺,超过3个月后焊盘氧化严重,波峰焊接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. 在整个生产过程中请对模块进行ESD(静电放电、静电释放)保护;
  7. 为了确保产品的良好品质,生产时需重点关注助焊剂的喷涂量,波峰高度,波峰焊锡缸内的锡渣和铜含量是否超标,波峰焊接治具开窗和治具厚度是否合适以及波峰焊接炉温曲线的合理性。

推荐炉温曲线和温度建议

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:
