<fabricationnotetext />

Overview

<fabricationnotetext /> lets you drop short build notes directly onto the PCB fabrication layer. These notes are useful for communicating assembly instructions such as "do not populate" or "install on second pass" to your manufacturer. Fabrication notes are only exported with fabrication outputs—they do not appear on the silkscreen or schematic.

Basic Usage

Below is a simple board with a fabrication note reminding the assembler about a special assembly step. The note is positioned by its PCB coordinates and can be aligned using anchorAlignment to point at a specific area of the board.

export default () => (
  <board width="24mm" height="18mm">
    <resistor name="R1" resistance="10k" footprint="0402" pcbX={-5} pcbY={0} />
    <led name="D1" footprint="0603" pcbX={5} pcbY={0} />
    <fabricationnotetext
      text="Install connector last"
      pcbX={0}
      pcbY={6}
      fontSize="1.6mm"
      anchorAlignment="top_left"
      color="#d97706"
    />
  </board>
)

Properties

Property	Type	Description
text	string	Message to display on the fabrication drawing.
pcbX	length	X coordinate of the note, measured in PCB units (defaults to 0).
pcbY	length	Y coordinate of the note, measured in PCB units (defaults to 0).
anchorAlignment	enum	Alignment of the anchor point relative to the text. Options: "center", "top_left", "top_right", "bottom_left", "bottom_right". Defaults to "center".
fontSize	length	Height of the rendered text. Defaults to 1mm if not provided.
font	enum	Currently "tscircuit2024". Optional—rarely needs to be changed.
color	string	Optional hex color to highlight the note in previews.
pcbRelative	boolean	When true, pcbX/pcbY are relative to the parent group instead of the board origin.
relative	boolean	Similar to pcbRelative, but also applies to schematic coordinates when used inside groups.

Tips

• Keep fabrication notes concise so they remain legible when exported to Gerbers or assembly drawings.
• Use distinct anchorAlignment values to align the note with the area or component it refers to.
• Combine fabrication notes with <group /> to move related callouts together when laying out subassemblies.
• Fabrication notes are separate from silkscreen text—they will not print on the final PCB silkscreen layer.
