HDI designs are reviewed together with multilayer PCB, impedance control and testing requirements.
HDI PCB
HDI PCB manufacturing review for compact high density electronics.
YBCPCB reviews HDI PCB projects by stackup, drilling structure, component density, material selection and inspection requirements before production planning.
HDI PCB introduction
High density interconnect PCB is used when product size, routing density and component pitch require tighter design coordination than a standard multilayer board. Feasibility should be confirmed with complete manufacturing data.
Manufacturing review focus
- Stackup, dielectric structure and controlled impedance notes.
- Drill strategy, via structure and pad-to-trace density.
- Surface finish, inspection needs and assembly compatibility.
