Crystal oscillators is a kind of active electronic components.Its upstream industries includes quartz grow, raw material production and precise machine.And downstream inductries include communication,customer electronics,car etc. Producing crystal oscillator includes designing, packing,testing etc.
IoT is one of the most potential industries. IoT is promoting the transformation and upgrading oif traditional industires.It also stimulates the developement more new industries. As the fifth generation developes, various monitors are required more and more. So the precision of equipments have to need higher precise raw materials to adapt different enviroment. This is a good chance for frequency control devices. High precision oscillators are stimulated growth.
