Ultrasonic Spraying LGA Dazzling High-gloss Coating

Ultrasonic spraying LGA dazzling high-gloss coating: dual innovation of 5G terminal appearance and function

With the advent of the 5G era, the stability of signal transmission has become the key to the development of electronic equipment. The interference problem of traditional metal back shells on 5G signals has become increasingly prominent, and terminal devices such as mobile phones and tablets have adopted non-metallic materials such as ceramics, composite boards, and glass as back shells. At the same time, the development of hardware technology has entered a bottleneck period, and the appearance design has become the focus of brand competition. The colorful high-gloss coating that is both beautiful and practical is very popular. As a standard function of the device, fingerprint recognition still occupies more than 70% of the market share due to cost advantages in the context of the popularization of full-screen displays, which puts higher requirements on the performance of fingerprint coatings. Ultrasonic spraying LGA dazzling high-gloss coating technology just meets the current terminal equipment’s demand for coating products that are both reliable, beautiful and functional.

The unique process of ultrasonic spraying LGA dazzling high-gloss coating gives the fingerprint coating excellent performance. In terms of thickness control, this technology can accurately control the total thickness of the product coating to about 45um. This thickness design will not only not affect the overall lightness and thinness of the device, but also meet the penetration requirements of more than 95% of the chips on the market, ensuring that the fingerprint recognition module can work stably and quickly, and avoiding signal attenuation or recognition delay due to excessively thick coating.

High temperature resistance is an important indicator for measuring coating reliability. The ultrasonically sprayed LGA dazzling high-gloss fingerprint coating can perfectly adapt to the 220-degree SMT high-temperature environment, maintain structural stability during the welding process, and meet the strict welding reliability requirements. This feature provides a guarantee for the large-scale production of terminal equipment, effectively reducing the defective rate caused by coating shedding and deformation due to high temperature, and improving production efficiency and product quality.

In terms of surface hardness, the coating also performs well and can reach the high hardness standard of 3H 1000G. The high-hardness coating is like a solid “protective shield”. In the transportation and assembly of module production, it greatly reduces the scratches caused by friction and collision, which not only ensures the integrity and beauty of the product appearance, but also lays the foundation for the smooth progress of subsequent processes.

It is worth mentioning that the ultrasonic sprayed LGA dazzling high-gloss fingerprint coating does not contain any conductive material, which fundamentally solves the signal interference problem caused by the presence of metal powder in the capacitive fingerprint coating. This feature ensures the stability of the capacitance value of the capacitive fingerprint sensor, makes the collected fingerprint image clear and complete, effectively improves the accuracy and sensitivity of fingerprint recognition, and brings users a more convenient and safe unlocking experience.

In addition, the LGA dazzling high-gloss coating can also give the terminal back shell a colorful appearance. Through the precise control of ultrasonic spraying technology, a variety of effects from matte to highlight, from single color to gradient colorful can be achieved to meet the personalized aesthetic needs of consumers. CHEERSONIC continues to upgrade the technology of ultrasonic spraying equipment and optimize the intelligence of the equipment. The intelligent control system can monitor the spraying process in real time and automatically adjust the parameters to ensure that every terminal product can obtain high-quality LGA dazzling high-gloss fingerprint coating.

At a time when 5G terminal equipment pursues a balance between appearance and performance, ultrasonic spraying LGA dazzling high-gloss coating technology, with its multi-dimensional advantages, will surely become an important force to promote the development of the industry and help terminal products stand out in market competition.
