Chinese How to Address the Stress Generated by a PCB Depaneling Machine?
How to address the stress generated by a PCB depaneling machine? It’s a question many engineers don’t ask—until defects start showing up. Cracked edges. Intermittent failures. Reduced yield with no obvious root cause. In many cases, the issue isn’t assembly.It starts with depaneling. 🔍 Where Does Depaneling Stress Come From? Stress is introduced during the separation process. Different sources include: Even small forces can affect: The challenge is not eliminating stress—but controlling it. ⚙️ How Different Depaneling Methods Affect Stress Not all machines behave the same. Here’s a simplified comparison: Method Stress Level Key Characteristics Saw Blade Medium High speed, mechanical contact Router Low-Medium Controlled cutting, flexible paths Laser Very […]
