Description This command is used to fanout the pads of the selected surface mount components that connect to both signal and power plane nets, in accordance with defined fanout design rules.

Use First, ensure that each SMT component whose pads you wish to fanout has been selected in the main design window.

After launching the command, each component in the selection will have its signal and power pads fanned out, where possible. The fanout process follows the applicable Fanout Control design rules that have been defined.

Notes If a component contains pads that are not connected to any nets, a dialog will appear asking if you wish to fanout these pads as well.

Running this command is equivalent to running both the Fanout Signal and Fanout to Plane passes in a strategy defined for the Autorouter.

The following default Fanout Control design rules are automatically created, covering the typical component package types available (listed in descending order of priority):

Fanout_BGA - with a query of IsBGA

Fanout_LCC - with a query of IsLCC

Fanout_SOIC - with a query of IsSOIC

Fanout_Small - with a query of (CompPinCount < 5)

Fanout_Default - with a query of All

These rules can be edited or others defined, in accordance with your individual design requirements.

The style used for the fanout vias will follow the applicable Routing Via Style design rule(s). Additional track laid down as part of the fanout process from pad to via will follow the applicable Routing Width design rule(s).

If you use any of the fanout commands before autorouting the board, there is no need to lock the preroutes, unless you have additional manual routing or have modified the fanout routing in some way.
