The HDI Design & Engineering Workflow
HDI success requires a meticulous, phase-gated approach. Our workflow is built to manage complexity proactively, ensuring every design decision supports manufacturability and performance from the start.
Density Analysis & Strategy
We assess component placement and netlist complexity to define the optimal HDI stack-up and technology path (e.g., laser vs. mechanical drilling), establishing a feasible foundation.
Critical Net Planning & Constraint Setting
High-speed and critical signals are planned upfront, setting rules for impedance, length matching, and via usage to prevent signal integrity issues in the dense layout.
Layer-by-Layer Routing & Via Optimization
We execute routing with a focus on via-in-pad and microvia utilization, minimizing layer count and maximizing space efficiency while adhering to fabrication capabilities.
DFM/DFA Review with Fabrication Partner
The layout undergoes a joint review with our manufacturing team, aligning design choices with process capabilities to eliminate yield risks early.
Prototype Data Package & Panelization
We prepare a complete data set including Gerber files, drill charts, and a panel drawing optimized for HDI processes like laser drilling and sequential lamination.
Production Ramp-Up Support
We monitor the first production run, providing engineering support to ensure a smooth transition from prototype to volume manufacturing.
Why Partner with Us for HDI Design?
HDI design decisions directly determine your product’s manufacturability, cost, and timeline. A layout that looks perfect in CAD can still lead to low yields and delayed launches if not aligned with fabrication reality. We ensure your design is not only dense and high-performing, but also optimized for reliable, scalable production—turning advanced layouts into deliverable products.
- Design for Manufacturing at the Core – We don't just design for density; we design for the laser drill, the plating bath, and the lamination press. This manufacturing-aware approach prevents costly delays and ensures your design is viable at scale.
- Risk Mitigation Through Process Experience –HDI introduces new failure modes. Our experience allows us to pre-empt issues like copper cracking in stacked vias or laminate misregistration, building reliability into your board's architecture.
- Unified Design-to-Production Responsibility – As your single point of contact, we manage the entire journey. This seamless integration between design and our factory floor accelerates timelines and ensures accountability for the final product's performance.

Ready to Pack More Performance into Your Product?
HDI typically carries a higher initial cost per board due to advanced processes like laser drilling and sequential lamination. However, it often reduces the total system cost by enabling a smaller size (saving on enclosure, shipping), fewer layers than a conventional dense layout, and higher assembly yields due to better design for manufacturing.
The key risks are microvia reliability (cracking), laminate registration errors, and plating voids in high-aspect-ratio holes. We control these through strict process parameters, controlled impedance models, and by designing within proven capability limits. Every batch undergoes cross-sectioning and microvia reliability testing.
We can often perform a successful HDI redesign from an existing schematic and layout. The process involves analyzing the current layout, proposing a new HDI stack-up, and re-routing with microvias. Starting from a known-good design can significantly reduce engineering time and risk.
To provide a meaningful proposal, we need:
- Your schematic,
- Critical component datasheets (especially BGAs),
- Board outline and mechanical constraints,
- Key performance requirements (speed, impedance, thermal).
With this, we can assess complexity and provide accurate scope.
