Embodiment Construction
[0025] As is well known, various printed circuit boards are widely used in the electronics industry. These printed circuit boards have both "single panel" and "double panel". When they are used in circuit design, surface mount technology (SMT) is usually used to increase the mounting density of electronic components, reduce product volume, and reduce production and assembly costs. .
[0026] Aluminum-based printed circuit board is a unique metal-based copper clad laminate, which has good thermal conductivity, electrical insulation and machinability. Aluminum substrates can replace fragile ceramic substrates to obtain better mechanical durability; moreover, aluminum substrates can effectively deal with thermal diffusion, thereby reducing product operating temperature, improving product power density and reliability, and prolonging the use of products life. Therefore, the aluminum substrate is an important variety of printed circuit boards.
