Interactive Stack-up Tool
Map Density to a Stack-up
Once you know HDI is needed, this maps your density to a starting stack-up: 1+N+1, 2+N+2, or any-layer.
- 1+N+1Single fine-pitch BGA, entry-level HDI
- 2+N+2Denser routing, second microvia layer
- Any-layerMicrovias on every layer, highest density
HDI Build-Type Selector
Once you know HDI is needed, this maps your density to a starting stack-up: 1+N+1, 2+N+2, or any-layer.
Starting point only. Final stack-up depends on impedance targets, aspect-ratio limits, and copper-fill requirements — all confirmed on PCBark’s DFM review.
