Printed Circuit Boards (PCBs) are robust, insulating boards created on a substrate
foundation,exemplified. Their primary role is to establish electrical
connections and provide structural support to a circuit's electronic components.
Commonly found in a myriad of electronic devices, PCBs are typically recognizable
by their green color. These boards are designed to accommodate various active components
like operational amplifiers and batteries, as well as passive components, including
inductors, resistors, and capacitors, aligning with the specific design needs and
dimensions of the intended final product.
