Information
When it comes to quality inspection, we all think of the PCB manufacturing industry in the electronics industry. Today, the Xiaowei multi-layer circuit board is to be shared with you. It is about the quality inspection of the circuit board of the multi-layer circuit board factory. Interested friends can Take a look.
 
The quality can be modified with poor adjectives, good and excellent adjectives. Characteristics can be inherent or imparted, qualitative or quantitative; categories of properties are physical (eg mechanical, electrical, chemical or biological), sensory (eg olfactory, tactile, taste, visual, auditory), behavior (such as courtesy, honesty, integrity), time (such as punctuality, reliability, service life), functional (such as the flight height of the aircraft, flight speed), then how to control the quality of our circuit board factory? What is the role and significance?
 
The development process of quality management has gone through three stages, namely, the quality inspection management stage, the statistical quality management stage, and the total quality management stage. Quality inspection is the first method used in quality management, and it continues to be applied and continuously completed in various quality management in the future. Quality inspection is still required in the current quality management system. Whether it is Shenzhen circuit board factory or other multi-layer circuit board factory is such an inspection 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 an important role. The formation of product quality is affected by subjective and objective factors such as personnel, machinery, materials, methods, and environment. It is a complex process in which the upper and lower processes are closely linked, and fluctuations in product quality are inevitable. Therefore, quality inspection must be carried out at all stages or in various processes of the board production process.
 
According to the different stages of the product realization process, the quality inspection is divided into three basic types: incoming inspection, process inspection, final inspection, and of course, our circuit board factory also has a final inspection.
 
1. Goods inspection: Acceptance inspection of raw materials, auxiliary materials, outsourcing parts and purchased parts before entering the factory. Do not use the unqualified materials and do not use them.
 
2, process inspection: also called process inspection, inspection of the in-process products in the production process of the production site. It not only prevents non-conforming products from flowing into the next process, but also prevents large-scale non-conforming products from appearing abnormally in the production process of the circuit board.
 
3. Final inspection: also called finished product inspection, inspection of completed 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, and the multi-layer circuit board factory is also like this, there is a final inspection of this process.
