Pcb Board Material Properties. The last of those layers substrate is made of fiberglass and is also known as fr4 with the fr letters standing for fire retardant. We use the following cem materials for pcb design.
Therefore it is necessary to define them during design so they can be incorporated into the manufacturing process. The material used in pcb from top to bottom includes silkscreen soldermask copper and substrate. For its function in helping to prevent solder shorts the coating is called solder resist or solder mask.
Your pcb material properties will determine the electrical mechanical and thermal behavior of this board.
The tracks function as wires fixed in place and are insulated from each other by air and the board substrate material. Tg is expressed in units of degrees celsius ºc. Power and heat impact on pcb material selection. Conductive copper tracks are printed or etched onto this con conductive base substrate.
