3D model¶
Drag to rotate, pinch or scroll to zoom, two fingers to pan. Built from the layout with the same 3D models as the renders.
Renders¶
Assembly: top only (25 parts on top, 0 on the bottom, counted from the layout; fiducials, mounting holes and parts excluded from the BOM are not counted).
fab.yml says assembly_sides: top (bottom has only the lga pads; paste on them is for the host board's reflow, not ours) but the layout has parts on top only — fix fab.yml (SOP-021 step 12).

Manufacturing specs¶
| Requirement | Value |
|---|---|
| layers | 4 |
| thickness mm | 0.8 (to confirm with the JLCPCB 4-layer impedance stackup; thin keeps the LGA module low) |
| material | FR-4 TG150 |
| copper oz outer | 1 |
| copper oz inner | 0.5 |
| surface finish | ENIG |
| solder mask | green |
| silkscreen | white |
| min track space mm | 0.127 / 0.127 (JLCPCB rule file) |
| min via drill mm | 0.3 |
| via treatment | tented |
| impedance control | yes, 50 ohm single-ended RF line (ANT to AE301), JLCPCB stackup |
| castellated holes | no (LGA: 40 pads on the bottom side, outer ends 0.3 mm from the edge) |
| edge plating | no |
| panelisation | single piece, fab may panelise |
| rule file | BLE54_Module.kicad_dru (the JLCPCB file; board is JLCPCB-only) |
| assembly sides | top (bottom has only the LGA pads; paste on them is for the host board's reflow, not ours) |
| assembly type | SMT only |
| dnp policy | parts marked DNP in the schematic are omitted from the BOM and CPL |
| notes | draft until layout; values marked "to confirm" are proposals |
