Inspection method for power adapter products


Do you know the inspection methods for electronic products?

1. Spot inspection: spot inspection is a widely used inspection method in current production. In the mass production process, electronic products cannot and do not have much time for full inspection. Usually several samples can be taken from the product to be inspected for inspection, that is, sampling inspection.


Spot check should be carried out on the premise of mature product design, process specification, stable equipment and reliable tooling. The number of samples to be taken shall be determined according to the base number of products to be inspected and the sampling standard in the national standard. When taking samples, they should not be taken from continuously produced products, but from the batch of products. The results of spot check should be recorded, and the faults in the spot check products should be judged against the relevant standards.


2. Full inspection: full inspection is the inspection of all products. Full inspection can improve the reliability of products, but will consume a lot of manpower, material resources, increase the production cost of products. Generally, only military products and other products with high reliability requirements, trial production products and products produced after the change of production conditions and production process are fully inspected. The quality of electronic products is often determined by product qualification level (AQL). For products with different quality requirements, their quality indicators are also different. During inspection, it should be determined according to the number of A and B faults allowed under the specified AQL value of the inspected products.


A qualified power adapter is inspected many times before it can be introduced into the market. Usually the inspection work mainly refers to the full-time inspection, that is, by the full-time personnel of the quality management department of the power adapter manufacturer according to the corresponding technical documents.
