In Case You Missed It

摘要

The high-end server market presents several manufacturing and technical challenges to socket manufacturers. Among the five notable trends: 1) Lower contact resistance. Contact resistance has a negative impact on current carrying capability and leads to higher socket operating temperatures. Given space constraints, the best approach to lowering contact resistance is by selecting materials with higher electrical conductivity. However, the tradeoff to higher conductivity materials is reduced mechanical performance. 2) Higher pin counts coupled with a need to maintain or lower socket loading force. Larger loading forces impact mechanical integrity and create ergonomic challenges. 3) Contacts with shorter electrical paths. As server frequencies increase, signal becomes more sensitive to noise.
