    Why do we need to introduce so many subdivided GND

    Categories: PCB Knowledge

     

    Why do we need to introduce so many subdivided GND functions? If in the circuit system, the circuit ground of different functions are connected together, it is equivalent to increasing a link of interference between the circuits.

    Aluminum PCB structure

    Categories: PCB Knowledge

     

    LED lights generally use a single-sided aluminum substrate, the circuit layer is mounted with the LED, and the aluminum base surface on the back can be in good contact with the radiator to dissipate the heat.
     
     

    Classification of different GND in circuit

    Categories: PCB Knowledge

     

    What is the nature of the ground in the circuit? During the PCB Layout process, engineers will face different GND treatments. Engineers generally introduce different ground as 0V reference points for different functional circuits to form different current loops.
