Fixing Missing Footprint Error
Thought for 44 sec
Here’s what I found for U8:
What U8 currently says in your project
Table
| Item | Value |
|---|---|
| Part | EM4305 |
| Manufacturer | EM Microelectronic |
| MPN | EM4305 |
| Package property | EM4205_EM4305_EMDFN02 |
| Package code | EMDFN-02 |
| Footprint property | EM4205_EM4305_EMDFN02 |
From the official datasheet for EM4305:
Table
| Datasheet item | Value |
|---|---|
| Package name | EMDFN02 |
| Package style | 2 leads Plastic Package |
| Body size | 2.20 mm x 1.78 mm |
| Thickness | 0.76 mm |
| Tolerance note | All dimensions in mm |
Table
| Pad name | Datasheet description |
|---|---|
| Coil 2 | Coil connection 2 |
| Test | Test purpose, NC, active pad |
| V test 1 | Test purpose, NC, active pad |
| V test 2 | Test purpose, NC, active pad |
| Coil 1 | Coil connection 1 |
The likely root problem is not just missing geometry. The part definition behind U8 appears incomplete.
The library entry for EM4305 is showing 0 terminals, which strongly suggests the part project does not have a valid symbol/terminal-to-footprint setup yet. That would absolutely cause a Missing Footprints-type failure even if a text property says “Footprint”.
What to fix in the part project
For the part project of EM4305, make sure it has:
Table
| Required fix | What to check |
|---|---|
| Footprint asset | A real footprint object exists, not just a footprint property string |
| Terminals | The part has actual terminals defined |
| Terminal mapping | Each terminal is mapped to the correct footprint pad |
| Package choice | Confirm whether you want the 2-lead EMDFN02 package or a bumped-die style implementation |
In the part project, verify these exact terminal mappings first:
Table
| Logical terminal | Map to footprint pad |
|---|---|
| Coil 1 | Coil 1 |
| Coil 2 | Coil 2 |
And if you include the test pads in the footprint, keep them as NC / non-user terminals unless your exact package variant requires otherwise.
If you want, I can now give you a click-by-click checklist for rebuilding the footprint and remapping the terminals for U8.
Clean up U8's terminals so Coil 1 and Coil 2 map correctly, and leave test pads as NC.
