The SMD command is used to add pads for surface mount devices to a package. When the SMD command is active, an smd symbol is attached to the cursor. Pressing the left mouse button places the smd pad at the current position and attaches a new smd symbol to the cursor. Entering numbers changes the x- and y-width of the smd pad, which can be up to 0.51602 inch (13.1 mm). These parameters remain as defaults for succeeding SMD commands and can be changed with the CHANGE command. Only even values should be used. Pressing the center mouse button changes the layer onto which the smd pad will be drawn, and the right mouse button will rotate the smd pad. The SMD command is active until ';' (or another command) is entered.

Names

SMD names are generated automatically and may be modified with the NAME command. Names may have up to eight characters and may be included in the SMD command if enclosed in single quotes.

Smd names with only three characters require much less memory than those with more than three characters.

Single Smds

Single smd pads in boards can only be used by defining a package with one smd.

Alter Package

It is not possible to add or delete smds in packages which are already used by a device, because this would change the pin/smd allocation defined with the CONNECT command.
