HDI technology ensures comprehensive control over signal integrity and offers superior electrical performance compared to standard PCBs. Stacked and staggered microvias are the driving factors in high-density boards since they enable dense component placement and versatile routing with optimized cost.

Staggered microvias have separate drill axes and are positioned offset to each other. For a perfect staggered design, the vertical separation between the centers of two microvias should be greater than the microvia diameter. So, if your board demands tight spacing restrictions, staggered vias might not be the best choice. These vias can withstand multiple thermal cycles and reduce signal reflection by trimming down the stub lengths.
