LED production process inspection (IPQC)

IPQC (InPut Process Quality Control) means process control in Chinese, which refers to the quality control of the product from the material input to the final packaging process. (Belongs to the Quality Control Department)
1. Responsible for the first inspection and part of the process inspection, the identification and statistics of defective products in the process; 2. Responsible for patrol inspection, and regular inspection of the entire production process, including material use, assembly operation, machine operation, environmental compliance, etc. 3. IPQC is generally the first inspection, patrol inspection and random inspection; it is a patrol flow inspection in the process; it is managed by the Quality Control Department.

In-process Quality Control (IPQC): Generally refers to the quality control of production activities from the time materials enter the warehouse to the time finished products enter the warehouse, i.e. In-process Quality Control. The quality inspection at this stage is called FQC (Final Quality Control).

LED process inspection (IPQC)
1~PQC inspection scope includes:
a. Products: the quality of semi-finished products and finished products.
b. Personnel: the quality of operator process execution and poor equipment operation skills.
c. Equipment: equipment operation status and load level.
d. Process and technology: whether the process is reasonable and whether the technology meets the requirements of product characteristics.
e. Environment: whether the environment is suitable for product production needs.

2~Process product inspection: There are great differences and flexibility in the inspection methods for product inspection. The inspection methods can be more flexible according to the actual production situation and product characteristics.
Full inspection by quality inspectors: Applicable to process products with multiple varieties and small batches and fatal defects when key processes are transferred. The workload is large. Those that are qualified are allowed to be transferred or put into storage. If they are unqualified, the operating staff will be required to rework or return for maintenance immediately.
Random inspection by quality inspectors: Applicable to process products with large batches, low single-piece value and no fatal defects when general processes are transferred.
Employee self-inspection: The operator first conducts self-inspection on the products he processes, and can only send them to the next process after the inspection is qualified. It can improve the qualified rate of product circulation and reduce the workload of quality inspectors. It is not easy to manage and control, and there are sudden abnormal phenomena from time to time.
Mutual inspection by employees: The operator of the next process inspects the products of the employees on the previous process, and can refuse to accept defective products from the previous process. Mutual supervision is conducive to mobilizing enthusiasm, but it can also cause quality abnormalities such as cover-up and quarrels.
Combination of multiple methods: Organically combine various inspection schemes, take advantage of their strengths and make up for their weaknesses, and prevent defective products from flowing into the next process or entering the warehouse, but the inspection cost is relatively high.

3~Process quality inspection: inspection of personnel, equipment, process technology environment, etc.
