## Materials and finish

As the datasheet states them (page.json `metadata.appearance`; the 3D model's colours follow it).

| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts |  | silver | will lead to the capacity of reflecting of silver layer reducing, light color temperature drift and serious decline ,seriously affecting | 9 |

## CAD (KiCad official)

- Symbol: `E6Q0603QBAC1UDA`
- Footprint: `LED_SMD:LED_0603_1608Metric`
- 3D model: 0603 (KiCad packages3D, STEP)
- 3D model files: `e6q0603qbac1uda-etched.step` / `e6q0603qbac1uda-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `e6q0603qbac1uda.step` / `e6q0603qbac1uda.glb` are the bare package body.
