    Why is film important in PCB manufacturing?

    2019-07-26

    As you probably know, the film is just like the same as the mold. Since the substrate of PCB is a copper clad laminate. When making a PCB, it is pretty necessary to etch away the unused copper foil, which is exactly the place where the film works.

    Which has better PCB thermal conductivity performance, ceramic PCB or metal PCB?

    2019-07-24

    Ceramic PCB is better. Due to ceramic board itself has pretty good insulativity, which means that it doesn’t need an extra insulating layer so that the thermal conductivity of ceramic PCB is much better than aluminum PCB (metal core PCB).

    What is the difference between an inductive load and a capacitive load?

    2019-07-23

    Inductive load: Allowing current to flow, and it can store energy in the inductor. The current lags behind the voltage; Capacitive load: Preventing current from flowing, and it can also store energy in the capacitor. The current is ahead of the voltage
