The pads are copper areas, typically circular or rectangular but may have any shape, used to fix the electronic components to the board and to create interconnection points between the component pins and the copper tracks. A pad can exist on a single layer of the board, as in the case of the SMD component pads, or it can assume a three-dimensional consistency by presenting a copper area on each layer and a central hole through the board. The pads are mainly used in making footprints but can also be used individually.
Number
Specify the pad number.
Name
Specify the pad name
Pad X, Pad Y
Pad center coordinates. To set the pad position based on the pad center coordinates, uncheck the Hole box and specify the coordinate values in the Pad X and Pad Y boxes.
Hole X, Hole Y
The coordinates of the center of the hole. To set the pad position based on the position of the hole center, check the Hole box and specify the coordinate values in the Hole X and Hole Y boxes.
Rotation
Specify the angle of rotation of the pad.
Net
Specify the net to which the pad is connected. If the Auto check box is selected, the pad is inserted into the connection determined by the other objects it is in contact with.
Test Point
Use these parameters to define the pad as a test point during board construction. A test point is a point where a test probe can come into contact with the PCB to verify the proper functioning of the board. You can specify a name for the test point and the side on which the measurement is to be made.
Short ID
Within the same footprint, pads that have the same Short ID value are considered electrically connected.
SMD Layer
For SMD pads, specify the layer on which the pad is placed.
Style
Select the pad style from the proposed list or create a new style.
