soundMeter_sm.sch, as shown in Figure 5-29. The addition of _sm indicates that this is the
surface-mount version. It has no special significance as far as EAGLE is concerned; it just allows us
to distinguish the two versions.

FIGURE 5-29 Saving the schematic to copy it.

After saving the copy of the schematic, you will notice that the Title field in the schematic’s frame
will now also be updated to soundMeter_sm, allowing us to tell our schematics apart should we
print them out.

Saving a copy of the schematic in this way will automatically create a copy of the board called
soundMeter_sm.brd that is linked to the new schematic.

Swap Parts on the Schematic

The surface-mount schematic (soundMeter_sm.sch) is currently exactly the same as the through-
hole schematic. We now need to go through the parts on the schematic and swap them for equivalent
SMD packages. The microphone and screw terminals will remain as through-hole devices.

Let’s start with IC1. Click the Replace command on the Schematic Editor’s Command menu and
then use “*7611*” as the search string (Figure 5-30).
