HDI pool Guidelines

Advanced PCB technology without unnecessary complexity

Integrate fine-pitch components, microvias and controlled high-speed signal transitions without turning the complete PCB into a fully customised HDI project.

Eurocircuits HDI Pool combines partial HDI technology and standardised build-ups with European PCB manufacturing and assembly for prototypes, NPI and low-volume production.

Before production, our digital-first platform provides transparent pricing and uses automated PCB and PCBA checks to identify detectable risks involving manufacturability, the BoM, component footprints, placement, polarity and availability.

Engineers receive these insights online within minutes, with expert support available when needed.

Advanced where necessary. Standardised wherever possible.

Is your design reaching the limits of standard PCB technology?

As electronic components become smaller and more densely packaged, standard PCB technology can reach its limits. Fine-pitch BGAs, CSPs, QFNs and similar packages often require:

  • Smaller vias for effective fan-out
  • More routing space between component pads
  • Removal of via stubs to maintain signal integrity
  • Controlled thermal pad connections to internal copper layers

In many designs, only one or two components create these advanced requirements. HDI pool applies HDI technology only where it is needed, keeping the remainder of the PCB conventional.

The result is a simpler, more cost-effective solution for prototypes, NPI and low-volume production.

What is HDI Pool?

HDI stands for High-Density Interconnect.

Eurocircuits HDI Pool provides access to microvia technology using a range of standardised PCB build-ups and manufacturing parameters.

Why HDI pool?

HDI where it adds value

A single fine-pitch component should not necessarily force the complete PCB into a complex, fully customised HDI manufacturing process.

What can HDI Pool help you achieve?

Integrate fine-pitch BGAs

Microvias can make it possible to fan out compact component packages where conventional drilled vias consume too much space.

What are the Practical applications of partial HDI

Eurocircuits and the HDI design experts at CIBOARD electronic developed a practical six-layer demonstration board using real component packages.

Who is HDI pool for?

HDI pool is intended for PCB designers and electronics development teams that need controlled access to microvia technology for prototypes, NPI and low-volume production.

Do you actually need HDI?

Not every fine-pitch component automatically requires an HDI PCB. The answer depends on the complete package, fan-out and routing problem, not on component pitch alone.

Why is HDI pool a practical solution for partial HDI?

HDI pool currently provides a defined manufacturing route for compatible designs, including:

How do you design for manufacturability from the start?

Start the PCB design with a known, manufacturable layer structure rather than adapting the completed layout to an available build-up afterwards.

Start your HDI design with confidence

Your design may need advanced interconnect technology. It should not need unnecessary complexity.

Eurocircuits HDI pool provides access to staggered microvias, fine-pitch component integration and controlled high-speed interconnect structures within a standardised, manufacturable and poolable PCB service for prototypes, NPI and low-volume production.

Pre-production verification through the Eurocircuits digital twin helps identify detectable design and manufacturability risks before production, supporting a Right First Time result.

Advanced where necessary. Standardised wherever possible.
