I. Performance:
VLRR (verification batch rejection rate), customer complaints, LRR (batch rejection rate).
The mission of SQE is to ensure the quality of incoming materials through the quality management of suppliers. Therefore, VLRR is the main reflection of SQE performance.
Two. Responsibilities:
For the purpose of ensuring the quality of incoming materials, SQE shall undertake the following four responsibilities:
1. Daily quality performance evaluation and audit of suppliers;
2. Quality supervision and abnormal consultation;
3. During the introduction of new /EC products, the supplier's process and product confirmation and continuous improvement (CIP);
4.GP products and their process control;
In view of these four responsibilities, the following is my experience:
1. Daily quality performance evaluation and audit of suppliers;
1. 1 Import new manufacturers:
The general contents include: general survey of new suppliers, QSA (quality system audit), QPA (quality process audit) and signing quality contracts;
1.2 QPA； for supplier's daily quality performance evaluation, monthly scoring and process audit;
Three elements of monthly TQR: technology. Quality. Response;
Once a month, the rating results are divided into A/B/C/D grades.
1.3 process audit (QPA) At the end of each quarter, SQE will make an audit plan for the next quarter.
Process audit method: for different stations, including incoming inspection, warehouse, MRB, P/L, secondary operation, OQC, packaging and inventory.
To sum up, the key projects are composed of five items: people, machines, materials, methods and environment, and the specific projects are assessed according to the company's QPA list.
Person: 1. Training 2. Comply with work instructions/standard operating procedures;
Machines: 3 devices/calibration. 4 Fixture/measurement;
Material: 5. Material zoning. 6. Shelf life/storage method;
Methods: 7 Tracing the source; 8. Statistical process control, self-examination and CLCA review;
Ring: 9 safety protection. 10 humidity/temperature;
QSA is usually reviewed once a year. According to ISO9000, according to the manufacturer's quality system, the management responsibility, resource management, product realization, measurement analysis and improvement are reviewed. Specific matters can be checked according to the company's QSA list.
2. Quality supervision and abnormal consultation;
According to the data of VLRR and LRR and customer complaints, the quality improvement of the manufacturer is monitored by reviewing the FMEA, 8D/5C reports of the manufacturer and the review results.
Through the inspection of the production line in the factory, check the implementation of abnormal quality improvement measures, and put forward relevant improvement requirements to guide the maintenance and improvement of manufacturers' quality.
3. During the introduction of new /EC products, supplier process and product confirmation and continuous improvement (CIP);
The introduction of new products, or the first production of EC products, must go to the manufacturer's production line to confirm the state of the process and the qualified state of the products, and review the relevant data such as TVR/FAI/CPK.
Check CIP related measures, such as FMEA, PMP, SPC, CLCA, etc.
4.GP products and their process control;
RoHS implementation, focusing on material identification control.
Can be used for material number, label, outer box identification, etc. Use SFCS control; ; Production line identification, material storage partition, etc.
3. Deal with the company's defective products
A good SQE should not only manage the quality of suppliers, but also deal with the company's defective products;
Here, the company's defective products are divided into two categories: VID (supplier-induced defect) and PID (production-induced defect).
1.SQE should be duty-bound to dispose of VID. Usually, according to the degree of product defects, manufacturers are required to 3R, that is, repair, rework and replace.
2. For PID, although it is caused by the operator of the company's production line, an excellent SQE should also help deal with some PID from the company's interests;
This is the general direction. In practical work, according to my experience, there are usually the following kinds of disputes:
1.The difference between vid and PID; When PQE (referee) is not very competent, controversy is inevitable.
2. The manufacturer is uncooperative and unwilling to handle the VID (rejecting 3 R).
3. The production line will mix PID into VID for the manufacturer to bear;
4. There will be an obvious PID, and there will be a production line owner. Please ask SQE to help push the manufacturer to help digest it.
Dealing with these three situations should be handled flexibly according to the situation; Personally think: good communication, win-win purpose.
