Overview
Definition
Panelization is the process of arranging multiple PCB boards into a larger manufacturing panel. Instead of fabricating and assembling individual boards separately, manufacturers process multiple boards together using a panel. Panelization includes board arrays, panel rails, tooling holes, fiducials, breakaway features, and manufacturing support structures.
Objective
Create a robust and manufacturing-friendly panel that supports fabrication, assembly, testing, and depanelization.
Why it matters
Poor panelization can cause panel flexing, assembly defects, misalignment, PCB cracking, low manufacturing yield, and increased production cost. Good panelization improves both quality and productivity.
