Add 2 terminal components to the part schematic.
In Flux part projects, pads are created from terminals in schematic, then configured in PCB. A terminal you place in schematic will generate a corresponding pad in the PCB editor .
Name the two terminals something simple like:
12
For a crystal, the pin type should be Passive if you set terminal properties later .
Set the pin numbers to match the package:
- terminal 1 -> Pin Number = 1
- terminal 2 -> Pin Number = 2
Pin numbers should match the package definition exactly .
Switch to the PCB editor.
Each schematic terminal will now have a generated pad in the footprint view, because Flux creates pads from terminals added in schematic .
Select pad 2 and set the same values:
- Pad Type =
SMD
- Width = 2.3 mm
- Height = 1.6 mm
Set the pad positions so the pad centers are 4.88 mm apart.
The easiest symmetric placement is:
- pad 1 center at X = -2.44 mm
- pad 2 center at X = +2.44 mm
- both pads at the same Y position
That gives exactly 4.88 mm center-to-center.
Optionally add silkscreen/body outline in PCB if you want the footprint to be easier to place and inspect. The critical electrical part is the two generated SMD pads; pad geometry is the essential footprint definition .
