A PCB creates the electrical interconnection network necessary for electronic chips to function and gives them a structured physical platform. Previously separate electronic chips can now collaborate closely to accomplish the intricate tasks needed by electronic devices thanks to PCBs’ precise routing, power distribution, and signal integrity control.
