3C electronics is a general term for communications, computers, and consumer electronics. With the rapid development of chip technology, the functions of 3C electronic products tend to be diversified, and they need to accommodate a large number of sophisticated electronic components in smaller and smaller shells. Therefore, when designing electronic products, it is not only necessary to consider aesthetics, but also to take into account the requirements of rapid heat dissipation and smooth signal transmission. Shape design and material selection have become a very critical part.
