HDI fundamentals
Understand where high-density interconnect earns its place, and which construction decisions come first.
What is an HDI PCB?
An HDI PCB uses compact interconnect features to increase routing density. The useful question is whether those features solve a real escape, size or signal-path constraint.
HDI fundamentalsHDI vs standard PCB: making the choice
Choose HDI when the additional interconnect freedom resolves a measured limitation. A conventional multilayer PCB can remain the better construction when routing space is sufficient.
HDI fundamentalsHDI Type I, II and III explained
IPC construction types and 1+N+1 notation describe different aspects of a board. Do not read Type II as an automatic synonym for 2+N+2.
HDI fundamentalsWhen does a design need HDI?
A blocked BGA escape, a fixed outline or an unacceptable interconnect stub can justify HDI. A small package pitch is a useful warning, not a complete decision rule.
HDI fundamentalsHDI PCB benefits and tradeoffs
HDI can improve usable routing area and shorten interconnects, while increasing process complexity and the need for construction-specific validation.
HDI fundamentalsHDI vs ultra HDI
Ultra HDI describes a move toward substantially finer interconnect geometries and more demanding fabrication control. Supplier definitions and production windows need to be compared explicitly.
HDI fundamentalsHDI terminology: a drawing checklist
A useful HDI vocabulary connects each term to a drawing feature: build-up, core, microvia, blind via, buried via, target land and capture land.
HDI fundamentalsThe HDI project workflow
Begin with an escape study, agree a manufacturable stackup, encode the rules, then complete layout and release verification.
