Ⅰ、Quality policy
Thoroughly tempered well-seasoned severe training and hammering to make competitive products!
Ⅱ、Quality Strategy
Continue to improve the quality constantly and record all issues for each batch sample and the mass production→Seeking out the precautionary measures,delving into quality hidden trouble→take relevant measures as precaution at the same time.

2. Quality Standard: IPC-A-610F-G class 2,
3. Quality control
Quality improvement activities: For product problems, comprehensive analysis from the aspects of human, machine, material, method, and environment, and implement quality improvement activities for all processes through PDCA
Continuous improvement plan: monitor quality implementation through weekly reports, monthly reports, and regular quality meetings, and formulate effective continuous improvement plans in a timely manner if it is found that the standards are not met
Engineering change and retrospective management: inspect and confirm the changed raw materials or finished products, and track management of model identification
Prevent recurrence of quality accidents: In order to prevent the recurrence of adverse events, the adverse events are included in the "Quality Resume Sheet" to collect and record the prone points, and the improvement methods are added to the control plan, FMEA, SOP and other documents
Staff training activities: For operators or quality personnel, conduct daily training on process discipline, zero defect concept, operation methods, defect identification and judgment, and quality issues at different stages
Continuous improvement of quality management: During the sample and trial production phase, PCBlayout production process, testing found problems and proposed improvement measures, and reminded customers to improve; Mass production phase, PCBlayout, production process, testing found problems and proposed improvement measures, and explored hidden quality hazards;

http://www.cn.nxp.com/about/sales-offices-distributors/asia-pacific/distributors.html
b. Standard part low volume or rush order： digikey、 element、 RS、 mouser
c. Unique part like PCB, will choose top 10 suppliers in Shenzhen, like Suntak Circuit Technology Co., Ltd and Tean Electronic, etc.
d. Compare price from 8 suppliers, to make sure we get the 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 stage：When 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
