, filling, electrical boundaries, etc., the main function of each component is as follows:
Solder pad: metal hole for welding component pins.
Over the hole: there is a metal hole and a non metallic hole, wherein the metal hole is used to connect the components between the various layers.
Mounting hole: used for fixing the circuit board.
Wire: electrical network copper film used to connect components pins.
Connector: used to connect components between circuit boards.
Fill: the application of the ground wire network, can effectively reduce the impedance.
Electrical boundary: for determining the size of the circuit board, all the components on the circuit board can not exceed the boundary.
