Definition
Conductor Spacing is the distance between adjacent copper features on the same PCB layer. It influences manufacturability, insulation resistance and signal integrity.
How It Works
Fabrication rules define the minimum spacing based on copper weight, etch process and reliability class. Higher voltages require wider spacing to prevent arcing, while high‑speed designs need controlled spacing to reduce crosstalk. DFM checks highlight areas where spacing falls below capability or safety limits.
Practical Example
A control board for 48 V power fails hipot testing. Engineers increase spacing from 0.2 mm to 0.4 mm, resolving insulation breakdown issues and improving safety compliance.
Context & Relevance
Conductor spacing is a fundamental design and inspection criterion that underpins both safety and electrical performance in printed circuits.
At Rework, we deliver hands-on training and IPC certification that helps teams understand and manage Conductor Spacing. Our on-site and virtual courses are designed to improve skills, prevent defects and support reliable electronics assembly.
