How to Eliminate Burrs in the PCB Depaneling Process

In PCB manufacturing, burrs—those tiny, unwanted metal or fiberglass edges—are a common issue during depaneling. They may seem minor, but they can lead to serious quality concerns such as electrical shorts, poor solderability, and reduced product reliability. This article explores how to eliminate burrs in the PCB depaneling process, comparing traditional and advanced methods, and sharing insights from real factory applications. ⚙️ Understanding the Root Cause of Burrs Burrs typically form when the cutting stress between the tool and PCB substrate exceeds material tolerance.Key causes include: In manual or saw-blade depaneling, mechanical contact is the main culprit. Operators apply force inconsistently, and even small deviations in angle or speed can […]
