Printed circuit board is based on what basis the processing of the circuit board
Printed circuit boards are not integrated together, by a number of components and devices (which can also have integrated circuits) combination. Its assembly process, does not involve the semiconductor process.
The integrated circuit (IC) is a circuit that integrates it into a separate device. Its manufacturing process is basically a semiconductor process.
The printed circuit board (PCB) is used to provide electronic components of the electrical connection of the physical hardware, from the actual manufacturing point of view.
