Pad Fanout

JLCEDA / EasyEDA Pro PCB Pad Fanout Via Plugin v2.3.5

Features

Automatically create fanout vias and traces for selected pads in PCB design.

Key Features:

• Single Pad Fanout: Select a single pad and fan out via direction buttons or staggered length setting
• Batch Fanout: Box-select multiple pads and fan out all at once in a unified direction, executed in pad number order
• Direction Button Fanout: UI provides 8 direction buttons; all pad shapes support 8-direction fanout
• Cursor Fanout: Enable cursor fanout mode, then click on empty canvas to automatically determine direction and fan out
• Blind/Buried Via Support: Automatically reads blind/buried via configuration from PCB design rules; supports through-hole, blind, and buried vias
• Design Rule Following: Automatically reads via size and trace width from PCB design rules as defaults on startup; supports mm/mil unit auto-detection and switching
• Net Rule Following: When switching pads, automatically updates default trace width based on the selected pad's net rules
• Staggered Fanout: Set stagger length for both single and batch pad fanout; adjacent pads alternate between different fanout lengths
• Collapsible Panel: Main panel collapses to a mini popup with refresh, cursor fanout toggle, and expand button
• Rotated Pad Support: For non-circular pads with rotation, direction buttons correspond to consistent dial directions
• Persistent Settings: Remembers the last used trace length setting

Usage

1. Launch the plugin from the EDA top menu: Pad Fanout → Pad Fanout…
2. Single-click or box-select pads on the PCB canvas
3. Click direction buttons in the UI panel to fan out; or enable "Cursor Fanout" toggle and click on empty canvas
4. Adjust the following parameters in the UI panel:
   • Via type (through-hole / blind / buried)
   • Via outer diameter, hole diameter (mm/mil)
   • Trace width, trace length (mm/mil)
   • Stagger length (for alternating trace length in fanout)
5. Click "↺ Refresh" to re-read current PCB design rules
6. Click "−" to collapse the main panel; a mini popup appears when collapsed

Notes

• When box-selecting multiple pads, cursor fanout uses the pad closest to the mouse cursor as the reference point for direction determination
