 2. Procurement policy：

    a. Standard part mass order, like IC, will only use authorized agents from original manufacturer's official website

        http://www.cn.nxp.com/about/sales-offices-distributors/asia-pacific/distributors.html

    b. Standard part low volume or rush order： digikey、 element

    c. Unique part like PCB, will choose top 10 suppliers in Shenzhen, likeHuaxiang Circuit Tech, etc.

    d. Compare price from 8 suppliers, to make use we get reasonal best price.

    e. Use alternative parts after customer's approval, and on the premise that no compromise of quality.

 3. Components inspection：

    a. Sample stageWhen there is new part, product engineer will strictly inspect every part according to component datasheet.

    b. Mass order procurement：IQC inspection according MIL-STD-105E sampling inspection class II standard

    c. Materials inpection equipments：
