With the development of the electronics industry, traditional screen printing is far from being able to meet the characteristics of the electronics industry with a large number of products, different product sizes, numerous models, and higher and higher marking requirements. Manufacturers now use inkjet printers to mark, usually using inkjet printers to print the part number, production time, storage date and other information. Inkjet printers are non-contact coding technology, which can meet the needs of the electronics industry. Product identification needs, whether it is on small resistors and capacitors, connectors, or other larger components such as switches. Can print Chinese characters, English, numbers, bar codes, graphics and other product information. The inkjet printer has realized automatic production, which not only effectively reduces costs, but also improves production efficiency, so it is welcomed by the majority of manufacturers. Benefits brought by the use of coding technology: 1. There are many products in the electronics industry that require internal and external identification. By printing clear and stable product specifications and assembly or storage time, products can be quickly identified, and the identification is not easy to wear. Ensure the durability of transportation and storage. 2. Generally, the industry and laws and regulations stipulate that manufacturers must indicate the origin, specifications, manufacturer and other product information on the packaging or outer box of the product. The use of coding technology can meet these regulations to ensure that customers sell in the market and export products. And other aspects of business behavior meet these standards. 3. Logistics requirements. Printing barcodes on product packaging can speed up the classification and circulation of products, make the management between production lines and warehouses more reasonable and scientific, and strengthen the monitoring of raw material consumption and effective inventory management. 4. With the increase in the added value of products, for users, clear and accurate logos are a standard way to recognize the brand, and it is also a sign of confidence in long-term safe use. For manufacturers, the use of coding technology can improve the brand's market image And unified logo management, establish a good identification image and beautify the appearance of products.
