Fast-growing produces, its point of longitudinal branch structure is processed simpler, three-dimensional structure relative to micro-structure reflecting mirror and can not only be installed more
Functional module, also more convenient for computer circuitry layout designs.
It, can chip, sensor, display module, communication module on it as high speed and high-bandwidth communication substrate
Etc. modules and wiring board, can be used for making the substrate of computer and supercomputer, sensor base plate and artificial intelligence system
Substrate etc..
