The Essential Guide to PCB Via Protection: Strategies and Standards
Ensure the long-term reliability and performance of your PCBs by understanding the critical role of via protection. In this comprehensive guide from PICA Manufacturing Solutions, explore IPC-4761-compliant strategies including unprotected vias, mask-tented vias, plugged and epoxy-filled vias, and copper-filled microvias—each with unique advantages for different density, environmental, and mechanical requirements. Learn how advanced protection methods like filled vias with cap plating support SMT pad integration, heat transfer, and space optimization in HDI and flex circuit designs. Backed by industry standards and decades of manufacturing expertise, this guide helps engineers choose the optimal via protection technique for cost-effective, high-reliability PCB assemblies.
