Quality Inspection of Multilayer Circuit Board Factory

When it comes to quality inspection, we all think of the PCB manufacturing industry in the electronics industry. Today, the editor of the multilayer circuit board will share with you some related matters of the circuit board quality inspection of the multilayer circuit board factory. Interested friends can take a look. Look.
 
   quality can be modified by 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 if it is timely (such as courtesy, honesty, integrity), time (such as punctuality, reliability, service life), and functional (such as airplane flight altitude, flight speed)? What are the functions and meanings?
 
   The development process of quality management has gone through three stages, namely, quality inspection management stage, statistical quality management stage, and total quality management stage. Quality inspection is the first method used in quality management, and will continue to be applied and perfected in various quality management in the future. Quality inspection is still required in the current quality management system. Whether it is Shenzhen PCB Factory or other multilayer PCB factories, this is the inspection system.


Quality Inspection of Multilayer Circuit Board Factory

   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 circuit board 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 circuit board factory also has final inspection.
 
  1. Goods 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: 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 occurrence of large quantities of unqualified products in the production process of the circuit board.
 
  3. Final inspection: also called finished product inspection, the 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. This is also the case for multi-layer circuit board factories. There is a final inspection process.
