Printed Circuit Boards (PCBs) are crucial components in electronic devices, providing a platform for interconnecting electrical components. Composed of insulating substrate material like fiberglass, epoxy, or phenolic resin, PCBs feature conductive copper traces that facilitate the flow of electrical signals. Electronic supports refer to structures, often PCBs, that hold and connect electronic components. These supports ensure stability and proper alignment for components like resistors, capacitors, and integrated circuits. Modern PCBs employ advanced manufacturing techniques, including surface mount technology, enhancing compactness and reliability in electronic systems. Both PCBs and electronic supports play pivotal roles in the functionality and efficiency of electronic devices.
