Electronic components are an integral part of electronic components and small electrical machines and instruments. They are often composed of several parts and can be used in similar products; It often refers to some parts of electrical appliances, radio, instruments and other industries, such as capacitors, transistors, hairsprings, clockwork and other sub devices. Common are diodes and so on. In the manufacturing industry, the four main items that have a direct impact on product quality are usually design, incoming materials, manufacturing process and storage and transportation. Generally speaking, design accounts for 25%, incoming materials for 50%, manufacturing process for 20% and storage and transportation for 1% to 5%. To sum up, incoming material inspection plays an overwhelming role in the company's product quality, so we should raise the factory's incoming material quality control to a strategic position.

Electronic components include: resistors, capacitors, potentiometers, electronic tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, electroacoustic devices, laser devices, electronic display devices, photoelectric devices, sensors, power supplies, switches, micro motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectric, crystals, quartz Ceramic magnetic materials, substrate for printed circuit, special materials for electronic function process, electronic adhesive (tape) products, electronic chemical materials and parts, etc.

In terms of quality of electronic components, there are CE certification of the European Union, UL certification of the United States, VDE and TUV of Germany and CQC certification of China at home and abroad to ensure the qualification of components.
