material used for printed circuit board
A printed circuit board (pcb) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it.. Circuit board material. the circuit board foundation, sometimes referred to as the base, comprises the substrate (or core) and the laminate. the substrate is the non-conductive dielectric material, typically chosen based upon the dielectric constant, dk. laminates when used in conjunction with substrates provide the copper foil or surface. Printed circuit boards (pcbs) are thin boards made from an insulating material, with a metal coated surface, sometimes on both the top and bottom. etches are made in the metal with acid to create pathways for electricity to travel among various components which are surface mounted on the board with solder..
