DXF Drawing
Failed to load DXF drawing.
The DXF uses a
MILLING_CUTOUT layer and shows the 1.5mm non-plated full-height isolation slot centered at x=85mm on the 200×140mm board. Specify 2-layer FR4, ENIG in the fab order notes.Review package and DRC

PCB Layout Constraints — GLECS V4 Logic Controller
Board Setup
- Board outline: rectangle, 200mm × 140mm.
- Stackup: Standard 2 Layer.
- Board coordinate convention in Flux: board center at (0,0), so left edge is x=-100mm and right edge is x=+100mm.
Isolation Slot / Zone Boundary
- Required isolation boundary from the spec: x = 85mm from the left board edge.
- Flux center-origin coordinate: x = -15mm.
- Required slot width: 1.5mm.
- Required slot height: full board height, 140mm.
- Slot rectangle: x = -15mm center, width = 1.5mm; y = 0mm center, height = 140mm.
- Layout marker added: Isolation Slot Mechanical Cutout Marker.
Zones
Table
| Zone | Board Area | Flux Coordinates | Ground Policy |
|---|---|---|---|
| Relay / Switching Zone | 0–85mm from left edge | x = -100mm to -15mm | GND_RELAY only |
| Logic / MCU / LTE Zone | 85–200mm from left edge | x = -15mm to +100mm | GND_STAR only |
Hard Rules for Placement and Routing
- Do not place logic/LTE/MCU components in the relay zone.
- Keep K1, Q1, D2, relay contact terminal, and relay-domain side of U_OPTO1 on the left side of the isolation slot.
- Keep U_MCU, U_LTE, J_SIM, J_ANT, regulators, sensors, OLED/debug headers on the right side of the isolation slot unless a connector must be on an edge.
- No copper, fills, or traces should cross the isolation slot.
- GND_STAR and GND_RELAY must remain separated.
- Only the optocoupler path may bridge control intent across the isolation boundary.
Manufacturing Note
Verification on 2026-06-13: the isolation feature is not currently a real board cutout in the PCB manufacturing geometry. It is only represented by:
Isolation Slot Mechanical Cutout Marker— Top-layer rectangle at x = -15mm, y = 0mm.Isolation Slot Label— Top-layer text:1.5mm ISOLATION SLOT — NO COPPER / NO ROUTING ACROSS.
The board outline is still a simple 200mm × 140mm rectangle; no internal cutout, routed slot, Edge.Cuts feature, or board-outline slot was found. Do not release Gerbers for fabrication until this slot is converted into an actual routed/milled slot or explicitly included in fabrication drawings/notes accepted by the PCB manufacturer.
Conversion attempt on 2026-06-13: current Flux layout operations available in this project do not expose a true internal board cutout / routed slot primitive. The available operations can create outer board outlines, normal layout primitives, pads/holes, text, and markers, but not a reliable plated/non-plated internal 1.5mm × 140mm milled slot feature. Therefore the marker was intentionally left unchanged rather than replaced by a misleading non-manufacturable approximation.
Manufacturing workaround: include this slot explicitly in the fabrication drawing / order notes, or perform final mechanical cutout editing in the manufacturer’s CAM/KiCad/Gerber tooling before release. Confirm with the PCB manufacturer that the slot will be milled as a non-plated internal slot and that copper clearance is preserved on both sides.
Manufacturer mechanical drawing created on 2026-06-13:
GLECS_V4_isolation_slot_mechanical_drawing.dxf. This separate DXF should be supplied to the PCB fab along with the Gerbers as the milling instruction for the isolation slot. It contains:- 200mm × 140mm board outline.
- 1.5mm wide rectangular milling cutout spanning the full 140mm board height.
- Slot centerline at x = 85mm from the left board edge.
- Slot edges at x = 84.25mm and x = 85.75mm.
- Notes calling out non-plated routed/milled cutout and no copper crossing.
Required fabrication callout: 1.5mm wide milled isolation slot at x = 85mm from left board edge (Flux x = -15mm), spanning the specified isolation boundary, with no copper crossing the slot.
