5. RESPONSIBLITIES 职责：
5.1 PRD 生产部
5.1.1 Operators must clearly know the MSD list for each model.操作人员必须清楚地知道各个产品的防潮元件清单。
5.1.2 Operators must properly handle the MSDs package. 操作人员必须正确处理湿度敏感元件。
5.1.3 Stick and fill out ‘MSDs Tracking label ’on MBB. 在防潮袋上粘贴并填写‘湿敏元件跟踪标签’。
5.1.4 Monitor the storage and baking condition of the MSDs. 监控防潮元件的储存和烘烤情况。
5.1.5 Monitor the using status of the MSDs. 监控防潮元件的使用情况。
5.1.6 Inform ME relative staff to handle the special ca. 若有突发事件请及时通知ME 相关人员。
5.2 PE工艺工程部
5.2.1 Determine the MSDs storage and baking condition ba on component supplier’s guidelines(including component specification and anti-moisture label).根据元件供应商指引（包括元件说明河防潮标签）决定防潮元件的储存和烘烤条件。
5.2.2 Provide MSDs list for each model.提供各个产品的防潮元件清单
5.3 QA品质管理部
5.3.1IQC control Incoming material area temperature& RH, and check MSDs.
现代足球 IQC 控制来料验货区的温湿度，并查验湿度敏感元件 。
5.3.2 IPQC supervi MSD handling. All FPS IPQC responsibilities will be replaced by operator. IPQC监督MSDs的处理情况.所有电源项目的IPQC工作将由生产部作业员代替。
6. PROCEDURE 程序：
6.1 IQC 席梦思源于check the incoming material if it is MSDs.If it is not MSDs. then handling it as normal material; if it is MSDs, then check if the MBB is damaged and check if it exceed it’s shelf life.If either of over happened, then reject it to vendor. IQC检查来料是否为湿度敏感元件，如果不是，则按照普通物料处理；如果是湿度敏感元件，则检验其包装袋是否有受损和物料是否超出其保存期限。只要有上面两种情况之一发生，应将该物料退回供应商。
6.2 Warehou nd out the MSDs material to Production line according the principle of FIFO. 仓库人员根据先入先出的原则将湿度敏感元件发放给生产线。
6.3 Handing method MSDs on production Lines MSDs 物料在生产线上的处理方法
6.3.1 All relative operator shpuld know what is MSDs material, one way is that operator can know what is the MSDs according to ‘MSDs material list’, the other way is that operaors if it is packaged with vacuum bag on which there is MSDs sign, e picture1.
6.3.2 Operator in RIP shpuld stick ‘MSDs tracking label’(e attachment 1) on MBB before deliver MSDs to Production line. RIP仓的人员在将湿敏元件发到生产线前，要贴上‘MSDs追踪标签’（见附录1）。
6.3.4 Operator and record unaling time in ‘MSDs tracking label ’(e attachment1) on the MBB when open the MBb, then inspect the HIC, e picture 2. If the color of HIC turns into pink reading at factory environmental conditions, the MSDs must be nt to back before it be ud to mount. Baking condition e vendor’s spec or refer to table 4-1 and table 4-2 of JEDEC J-STD-033B(Note: MBB with ‘MSDs tracking label ’ should be kep until the MSDs is ud up). 在拆封防潮带时，上料员在防潮包装袋上的‘MSDs追踪标签’（见附录1）上填写开封时间，然后检查湿度指示卡，如图2。如果在车间环境下发现HI
C卡为粉红色，则此材料必须烘后才能使用。烘烤条件见供应商说明或JEDEC J-STD-033B的表4-1和表。（注意：粘有MSDs跟踪标签的防潮袋必须保存到湿度敏感元件用完为止。）
6.3.5 PRD must check ‘MSDs tracking lable’ of the MSDs every 4 hour ensure all the MSD are in their expod time,IPQC should sample check MSDs status random as well. If the component exceeds exposure floor life .it should be baked in over before next round u.Floor life e vendor’s spec or refer to table 6-1. 生产部每四小时检查温湿敏感元件一次，确保所有的元件没有过期，IPQC也应作不定期的检查。如果生产线上的温湿敏感元件暴露在空气中超过规定的时间，必须烘烤才能使用。暴露期限见供应商的说明或参考表6-1。
