The traditional way of sampling is usually caused by the user to produce the products produced at the test batch sent to QA, QA inspectors as required WI document, determine the number of sampling and sampling, there is a disadvantage in this way:
人为干预的因素太多，没有标准可言。
检验人员可能会按照顺序依次从第一个产品开始检验，导致分布不均匀。
判定结果不严谨。
判退工序不明确。
MTS system uses "dynamic test" method for sampling according to AQL standards and the level of inspection (normal, tightened, relaxation) generated automatically by the system and determining the number of samples tested batches, while targeting a sequence number required for each sampling, the whole process is completely generated by the system, the sampling become more random, avoid man-made cheating, improve inspector efficiency and reduce waiting time.
The rejection reasons
Quality personnel maintained in the system in advance the rejection reasons, such as production and operational reasons, the incoming reason, design reasons, test fixture other reasons, the system during the inspection result of the determination in accordance with the ACC and REJ AQL conditions, if the determination is FAIL, the inspectors choose a specific reason for the rejection of the actual situation, the rejection reason will be reflected in the QA sampling report.
The rejection process
When inspectors found defective products, it is necessary to determine the rejection process, that is to say that after the completion of the repair of defective products, from which a process resumes production, the system will determine the next target process defective products inspection personnel selection process based on.
Sampling process, the sampling found defective products forced into the service center waiting for repairs to be drawn into the yield of the rejection process inspection personnel selection.
