The quality inspection of the circuit board factory, the inspection standard that allows customers to rest assured

When it comes to product quality inspection, I believe everyone will almost think of (circuit board) processing and manufacturing. Today, the editor of the circuit board factory will share with you some related matters about the circuit board quality inspection of Shenzhencircuit board factory. Interested friends You can take a look.

Quality can be modified with adjectives such as poor, good, and excellent. Characteristics can be inherent or given, qualitative or quantitative; the categories of characteristics include physical (such as mechanical, electrical, chemical or biological characteristics), sensory (such as smell, touch, taste, sight, hearing), behavior How to control the quality of our circuit board factory? What are the functions and meanings?

The development process of quality management of PCB circuit board manufacturers has gone through three stages, namely, quality inspection management stage, statistical quality management stage, and total quality management stage. Quality inspection is an earlier method used in quality management, and will continue to be applied and completed in various quality management in the future. Quality inspection is still needed in the current quality management system.

Product quality is designed and manufactured, not tested, but quality inspection is an important factor in the quality system. In modern quality management, quality inspection also plays a very important role. The formation of product quality is affected by subjective and objective factors such as personnel, machines, materials, methods, and the environment. It is a complex process closely related to the upper and lower processes, and fluctuations in product quality are inevitable. Therefore, quality inspection must be carried out in each link or process of the production process.

According to the different stages of the product realization process, quality inspection is divided into three basic types: incoming inspection, process inspection, and final inspection. Of course, our PCB circuit board manufacturers also have final inspection.

(1) Incoming inspection: acceptance inspection of raw materials, auxiliary materials, outsourcing parts and outsourcing parts before entering the factory and warehouse. Make sure that unqualified materials are not put into storage or used.

(2) Process inspection: It is also called process inspection, which inspects the products in the production process at the production site. It not only prevents the unqualified products from flowing into the next process, but also prevents the abnormal production process from occurring in large quantities of unqualified products.

(3) Final inspection: also known as finished product inspection, inspection of finished finished products before storage and delivery. The inspection is carried out in full accordance with the customer's contract and relevant standards to ensure the customer's acceptance.

The above introduction about the entire quality inspection of the circuit board/circuit board factory is here. The control system of the circuit board factory also follows this process. If you want to know more PCB information or need to make circuit boards, please consult
