EP024-A Deep Dive into SMD and NSMD Pads for Enhanced BGA Performance
This deep dive compares SMD and NSMD pad designs for BGA solder joint reliability, focusing on cracking resistance and void reduction. SMD pads offer stronger board adhesion for mechanical stress resistance, while NSMD pads generally provide better solderability and potentially fewer voids. The choice involves trade-offs. Crucially, preventing cracking largely depends on the product's overall mechanical design, not just the pad. (Revised on 2025/04/28 at 17:50: Changed opening music.)
