5-1-7 The Spatial Reversal: The Performance Revolution of RDL and Flip Chip (Flip Chip Packaging)

Flip Chip's spatial reversal breaks wire bonding bottlenecks. RDL routes contacts from edge to interior; copper pillars connect directly to substrate, reducing latency, increasing bandwidth, optimizing cooling. Despite thermal expansion warping (needs underfill), it's crucial for AI chip compute ...
