In the light of specific functions, the button PCB is actually divided into touch button PCB, LCD button PCB, FPC button PCB, silicone button PCB, tickle button PCB, etc., and which is commonly used in remote control, panel board and so on.
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.
1. Preparing the PCB and the components that need to be soldered;
2. Choosing the soldering tools and preparing the solder and flux;
3. Mastering soldering technology (soldering basic method + soldering quality control).
1. Structure and installation requirements;
2. To prevent the high-voltage components and near the low-voltage components on the PCB from being fired;
3. Adding the thermal pad by slotting, then it doesn’t need to consider electrical Safety requirem
Static electricity from human body, environment and even electronic devices inside is able to cause various damages to those delicate semiconductor chips.
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).
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
Resistance is the most used component in all electronic circuits and whose main physical characteristic that is the conversion of electrical energy to thermal energy. It can also be said to be an energy-consuming component on account of generating heat af
