HDI PCB Design

High density interconnect (HDI) designs push the limits of trace, via, and layer density. These boards have high layer counts with very small traces and vias. HDI PCBs also require different fabrication and assembly processes than typical circuit boards that use larger features. Browse our library of resources to learn more about implementation of HDI PCB design.
