Multilayer HDI boards from 5 days. DFM review before production release

We design anything from simple 2-layer boards to 60-layer HDI with laser microvias. We validate manufacturability before you pay for fabrication.

Unique value proposition

The board is designed around components you can actually buy — not the ideal world of datasheets.

The classic problem: the circuit designer gets the customer BOM, creates an ideal topology, then procurement finds half the chips are on 26–40 week lead times. Re-layout = 2–4 weeks + validation + money. Our circuit designer sits in the same office as the component sourcing manager.

PCB Development Stages

  1. 1

    Requirements Specification

    We gather requirements: dimensions, interfaces, temperature range, EMC requirements. We create a block diagram and preliminary complexity estimate. Deliverable: signed specification with fixed cost and schedule.

    1–3 days
  2. 2

    Circuit Design

    Schematic design, power rail analysis, and component selection with availability in mind. We check every part against current stock.

    3–10 days
  3. 3

    Layout

    Component placement, routing, and characteristic-impedance control for high-speed lines (USB 3.0, HDMI, Gigabit Ethernet). Signal-integrity simulation when required.

    5–15 days
  4. 4

    DFM Review

    We check minimum clearances, trace widths, hole ratios, and thermal zones. We generate Gerber, production order, and Pick&Place data, then submit the package for factory review before launch.

    1–2 days
  5. 5

    Prototyping

    Fabrication of 2–5 samples. We check net integrity, solder joint quality, and dimensional compliance. Functional testing when firmware is available.

    7–14 days
  6. 6

    Documentation & Production

    Full package: Gerber, assembly drawing, BOM, soldering and test instructions. We support the first production run and clear early issues.

Features and details

HDI

High Density Interconnect — microvias and vias-in-pad for boards under 50×50 mm with BGA

Impedance Control

Precise characteristic-impedance matching for USB 3.0, HDMI, Ethernet, DDR

DFM

Design for Manufacturing — manufacturability review before production release

Rigid-Flex PCBs

Combination of rigid and flexible sections for foldable designs and medtech

Metal-Core PCBs

Aluminum substrate for heat dissipation — LED drivers, power electronics

Frequently asked questions

What is the maximum layer count?+
We design boards from 2 to 60 layers, including HDI with laser microvias. Topology complexity is discussed at the specification stage.
What is a DFM check?+
DFM (Design for Manufacturing) — verifying board manufacturability before production. Minimum clearances, trace widths, hole-to-pad ratios, thermal zones — we check all against the fab capabilities.
Manufacturing in Russia or China?+
We work with verified manufacturers in Russia and China. The choice depends on volume, deadlines, board complexity, and certification requirements.
What is the prototype turnaround time?+
2–5 sample prototypes — from 7 to 14 days after Gerber approval. Timing depends on board complexity and factory workload.
