Use the drop-down to select another template. If there is an associated Library, that library will be displayed. Template - displays the current template for the pad.

Ths field is dependent upon the net selected in the Net field and is not editable. Net - use the drop-down to select the net to which this pad belongs. All nets for the active board design will be listed in the drop-down list. Note that if pad placement commences at the same location as an existing object that is already connected to a Net, then the Net property of the new object is automatically assigned to that Net. Select No Net to specify that the pad is not connected to any net. The Net property of a primitive is used by the Design Rule Checker to determine if a PCB object is legally placed.

Let’s set the design rules for our drone PCB.įirst, we need to configure a basic rule for net-to-net clearance for all nets in our PCB.In the below properties listing, options that are not available as default settings in the Preferences dialog are noted as ' Properties panel only'. You will soon see that setting even the most complicated rules in Altium Designer is incredibly easy and clear. You can access the PCB Rules and Constraints Editor dialog at any time your PCB is open by selecting Design > Rules from the main menus. The rules in Altium Designer are set up using the PCB Rules and Constraints Editor dialog, which is a modern and powerful tool for design rules management. Rules in Altium Designer are presented in the form of a hierarchy - from the fundamental rules covering the entire board to the rules of individual net classes. Any mistake or failure to comply with the rules can lead to problems, up to and including the complete inoperability of the PCB or the impossibility to manufacture or assemble it.

These rules cover everything from the minimum width of the conductor to the maximum height of the component in a particular area of the PCB. These rules describe to CAD the restrictions for manufacturing, impedance control, and routing parameters, and what can and cannot be done within the design. Correct rules definition is a very important step in the PCB design process.
