  • Why use PCB prototypes

    Before you start a full production run, you need to make sure your printed circuit board or PCB is operating properly. Because PCBs are such an integral part of so many electronic devices, they can be very expensive if they fail or are not fully implemented after full production. Prototyping your...

  • Selection basis of printed circuit  width

    Selection basis of printed circuit width

    The minimum width of the printed wire is related to the amount of current flowing through the wire:  1: The line width is too small, the resistance of the printed wire is large, and the voltage drop on the wire is also large, which affects the performance of the circuit, If the line width is too ...
