    The difference between HDI board and ordinary PCB

    Author: Judy Chen | Catgorys: PCB Layout&Design

     

      High Density Interconnector (HDI), a high-density interconnect board, is a circuit board with a relatively high density of line distribution using micro-blind buried hole. The HDI board has an inner layer line and an outer layer line, and then uses a process such as drilling and metallization in the hole to connect the inside of ...

    Classic Circuit Analysis--Clock Circuit

    Author: Judy Chen | Catgorys: PCB Layout&Design

     

    In a circuit system, the clock is an essential part. The clock circuit is quite critical, which is like the function of the human heart. If the clock of the circuit system is wrong, the system will be disordered. Therefore, it is necessary to design a good clock circuit in the PCB. Our commonly used clock circuits are: crystal, crystal oscillato...
