Seprays Group: Which PCB Depaneling Method Causes the Least Stress?

Which PCB depaneling method causes the least stress? For engineers and production managers, this question often arises when dealing with sensitive PCBs. In SMT manufacturing, edge cracks, micro-stress, and component damage can lead to rework, delays, and higher costs. Choosing the right depaneling technique is critical to maintain quality and throughput. 🔧 Understanding Stress in PCB Depaneling Stress in depaneling arises from mechanical force, vibration, or heat. Methods like sawing and punching physically push the board, which can: Reducing these stresses is essential for fragile, high-density, or multi-layer PCBs. ⚡ Comparing Common Depaneling Methods Not all methods affect boards the same way. Here’s a practical overview: Method Stress Level Best […]
