When designing HDI or high-density boards, blind vias help free up routing space and cut down on via transitions, but I’ve noticed some PCB manufacturers don’t list them as a standard capability, or they require extra re…

We often see via-related issues during layout and DFM reviews because vias are frequently chosen for routing convenience. A via may look like a simple plated hole, but it can directly impact: Manufacturability …
