High-Reliability PCB Design Tips for Aerospace and Other Harsh Environments

This whitepaper by Summit Interconnect explores essential design strategies for developing high-reliability printed circuit boards (PCBs) used in aerospace and other harsh environments. It highlights the critical difference between quality and long-term reliability, emphasizing lifecycle performance under extreme thermal and mechanical stress. The paper reviews key IPC standards, material selection criteria, and thermal management techniques necessary for mission-critical applications. It also addresses common failure mechanisms such as via fatigue, CTE mismatch, and solder reliability challenges. Engineers will gain practical insights to enhance durability, performance, and system integrity in demanding operating conditions.
