One of the key concepts in electronics is the printed circuit board (PCB).
A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks. Simplest PCBs have only insulation board with copper traces on one side. More complicated PCB is sort of like a layer cake or lasagna- there are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object.
Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. It is estimated that the PCB market would reach $79 billion by 2024.
But how those PCBs are made in factories? Hare are few videos that describe how PCBs are made and how PCB factories work.
