    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.

    Difference between immersion gold boards and gold plating boards

    Categories: PCB Knowledge


    Immersion gold PCB and gold-plated PCB are processes often used in PCB circuit boards manufacturing. The difference between immersion gold PCB and gold-plated PCB

    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.
