material of printed circuit board
A printed circuit board, or pcb, is a self-contained module of interconnected electronic components found in devices ranging from common beepers, or pagers, and radios to sophisticated radar and computer systems. the circuits are formed by a thin layer of conducting material deposited, or "printed," on the surface of an insulating board known as the substrate.. 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 board material. circuit specialists carries affordable copper-clad and presensitized positive photoresist printed circuit boards (pcbs), which are ideal for prototypes or small production runs. these high quality circuit boards provide high resolution and excellent line width control.. 
material of printed circuit board Printed circuit boards (pcbs) are usually a flat laminated composite made from non-conductive substrate materials with layers of copper circuitry buried internally or on the external surfaces.. they can be as simple as one or two layers of copper, or in high density applications they can have fifty layers or more.. Most often printed circuit boards are made of standard glass-epoxy laminate namely fr4 type, with an operating temperature from -50 to + 110
