PCB bare board that is shorthand for printed circuit board , Chinese name for the printed circuit board , also known as printed circuit boards, printed circuit boards, it is important to the Department of Electronics
Member , the support of electronic components, electronic components are provided by the electrical connection . Since it is produced using electronic printing , so called " print" circuit board.
As electronic devices become more complex , more and more natural parts needed , PCB top of the line and the parts are more intensive . Bare board ( no top parts ) is also often referred to as " the printed circuit board Printed Wiring Board (PWB)". The board itself is made of an insulating substrate insulation, not easy to bend the material made into .
Can be seen on the surface of the fine copper wiring material , the original copper foil covering the entire board , part of the manufacturing process and in the etching process is away , leaving to become part of a fine mesh lines the . These lines are called conductors (conductor pattern) , or said wiring and connecting the circuit to provide the parts on the PCB .
PCB color is usually green or brown , which is solder mask (solder mask) color. An insulating protective layer can protect the copper can be prevented from
Part to be welded not only to the right place . Will be printed on the solder layer on the surface layer of screen printing (silk screen). Usually in it will be printed on text and symbols ( large Mostly white ) to mark the location of the parts on the board . Also referred to silkscreen icon plane (legend).
