1. Basic overview of quality inspection
IQC (Incoming Quality Control) quality control of incoming materials Number List is a key point before the transfer of property rights of goods. The results of inspection directly affect the loss of subsequent processing processes and the experience of goods flowing into users.
The type of quality inspection can be divided into two different dimensions: stage and inspection standard:
The quality inspection can be divided into new product inspection, bulk cargo inspection, on-site quality inspection, in-stock quality inspection, in-house inspection, and in-house sampling inspection. .
According to the inspection standards of quality inspection, it can be divided into delivery inspection, bulk quality inspection, and appearance inspection.
Inspection: Refers to the method of sending samples to a third-party officially certified laboratory for quality inspection. Because the laboratory is more professional and well-equipped, it generally conducts a full inspection of all standard indicators of the product.

The ability of quality inspection can be divided into three levels, including 1.0 initial level, 2.0 development level, and 3.0 advanced level.
The core keyword of the 1.0 initial stage is passive inspection. The main method is defense. Usually, based on the inspection standard, a sampling plan is formulated, the inspection is performed and the inspection result is recorded;
The 2.0 development-level quality inspection has changed from passive to active, and the key is to carry out standardized process control to carry out active early warning, to precipitate the quality inspection result data of the whole process, and to carry out series analysis of the whole process data, so as to determine the weak links caused by quality problems, To proactively intervene and optimize early warning;
