Overview
Definition
Fabrication Drawing Preparation is the process of creating a manufacturing document package that clearly defines how the PCB should be fabricated. It communicates board geometry, stack-up, materials, drilling information, copper requirements, surface finish, manufacturing notes, and quality expectations. Fabrication drawings eliminate ambiguity and reduce manufacturing errors.
Objective
Create a complete fabrication drawing package that enables the PCB fabricator to manufacture the board accurately without assumptions.
Why it matters
Poor fabrication documentation can cause incorrect board thickness, wrong copper weight, incorrect surface finish, wrong drill sizes, stack-up errors, manufacturing delays, and increased cost. Good fabrication drawings reduce communication issues and improve first-pass success.
