11 质量 QULITY 1. INTROUCTION Mass production of high quality ferrite cores requires a fundamental knowledge of processing rules dedicated to each material and the use of advanced production techniques. Existing products specifications are achieved mainly by the implementation of a reliable Quality ssurance System using Statistical Process Control (SPC) in the manufacturing processes. t each manufacturing step, the capabilities of processes are demonstrated through various controls performed on the related test vehicles. 2. STNRS N SPECIICTIONS Our ferrite cores are manufactured and controlled in accordance with G standards (National Standards of P.R.China), SJ standards (Trade Standards of Electronics Industry of P.R.China) and IEC standards (Standards of International Electrotechnical Commission). The standards are divided into three levels: GS = Generic Specification SS = Sectional Specification S = etail Specification Concerning soft ferrite parts and accessories, the following G standards are important for quality assessment and for choice of standardized core types and materials: G/T 9623 G/T 9624 G/T 9626 G/T 9628 G/T 963 G/T G/T 9634 G/T 9637 G/T 1192 G/T Inductor and transformer Cores for Telecommunications Part 1: Generic Specification Inductor and Transformer Cores for Telecommunications Part 2: Sectional Specification Magnetic Oxide Cores for Inductor pplications Inductor and Transformer Cores for Telecommunications Part 3: Sectional Specification Magnetic Oxide Cores for road-and Transformers Inductor and Transformer Cores for Telecommunications Part 4: Sectional Specification Magnetic Oxide Cores for Transformers and Chokes for Power pplication imensions of Pot Cores Made of Magnetic Oxide and ssociated Parts Measuring Methods of Inductor and Transformer Cores for Telecommunications Guidelines of Limit Specification External Shape efects of Magnetic Oxide Parts asic Terms and efinitions of Magnetic imensions of Spire Cores Made of Magnetic Oxides Inductor and Transformer Cores for Telecommunications Part 2: rafting Guidelines of Performance Specification Our soft ferrite pot cores production line has been inspected and validated as a production line implementing military standards by the Professional uditors of China for Military Electronic Components Quality Certification.

12 质量 QULITY 3. QULITY SSURNCE 3.1 System Our system complies with G/T192- ISO92, GJ92 and IECQ. Our corporate control plan can be divided into four main parts: ----Incoming inspection (IQC) Not only there is restriction on the scope and number of suppliers, but also the key parameters of each batch of raw material are inspected by our inspectors when it enters our factory and is put in storage. ----Processing inspection (IPQC) t each process, semi-finished products are tested or controlled by SPC method so that the finished products comply with the specification. Each important process is followed by a Quality Control Point (QCP) where the decision is made to continue or stop the batch if unacceptable parameters are found (nonconforming batch procedure). On the other hand, results from one process stop can be used to monitor the following step, e.g. results of granulation are used to define the pressing conditions of the relevant batch. typical example of manufacturing flow chart dedicated to MnZn ferrite cores is shown ig 1. or each process step, QCP controls are performed on the defined test vehicles. The relevant test vehicles could be powder samples or pieces of semi-finished ferrite parts. The complete flow chart is split into two main parts: powder reparation and core production. 1 JINNING SNHUN HI-TECH. MGNETIC INUSTRIL CO., LT.

14 质量 QULITY In ig. 1, QCP is Quality Control Point and SPC is Statistical Process Control. ----inished product Inspection (QC) Each batch must pass through a final outgoing inspection before entrance into the sales warehouse. uring the outgoing inspection, all results collected on relevant lot are checked, some samples are controlled and test report is printed upon request. ----Outgoing Inspection (OQC) Each batch must pass through a shipment inspection before taken out of the sales warehouse and delivered to the customers, to prevent the product with destroyed packaging or dim mark from outgoing. 3.2 Traceability The following information can be got from the label stuck on each packing unit: -- customer name and customer s part number -- material brand and type of core concerned -- code name of the inspector -- lot number -- name of the manufacturer and its address 4. QULITY CONTROL 4.1 Classification of efects ferrite core will be considered defective if it does not comply with the standard specification of our factory. Two levels of defects are defined: Major defects: may lead to an operating malfunction in the final winding or mounting processes. Minor defects: do not affect the operation or mounting of the wound components. Generally they are mechanical and visual defects such as cracks and chips. Table 1 giver hereunder defines the parameters, which must be considered as major or minor defects versus the type of product and applications. 12 JINNING SNHUN HI-TECH. MGNETIC INUSTRIL CO., LT.
