PCB Layout Design Service
We take a reviewed schematic and turn it into a manufacturable board — placement, stackup, routing, copper pours, and a fabrication package that a factory can build without asking questions.
What PCB layout design covers
PCB layout is the stage where electrical intent becomes physical geometry. Every decision here — where the regulator sits, how the ground plane is split, which layer a differential pair runs on — determines whether the board works on the first spin or the third. We treat layout as an engineering task, not a drafting task.
- Board outline, mechanical constraints, and mounting/connector alignment against your enclosure
- Layer stackup definition with dielectric thicknesses and target impedance
- Component placement driven by thermal, signal, and assembly considerations
- Power distribution network design — plane splits, decoupling strategy, copper weight
- Signal routing with length matching, differential pairs, and return-path continuity
- Design rule checks against IPC-2221 spacing and IPC-7351 land patterns
- Silkscreen, assembly drawings, fabrication notes, and a revision-controlled release
Layer count and what it costs you in complexity
Layer count is the single biggest driver of both fabrication cost and design time. Adding layers is often cheaper than the engineering hours spent trying to squeeze a dense design onto too few of them — and a 4-layer board with a solid ground plane will outperform a 2-layer board on EMC every time.
| Layers | Typical use | Design time | Notes |
|---|---|---|---|
| 2 | Simple sensors, breakouts, low-speed MCU boards | 5–8 business days | No dedicated ground plane; EMC needs care |
| 4 | STM32/ESP32 products, mixed-signal, most IoT | 2–3 weeks | Signal / GND / PWR / Signal — the practical default |
| 6 | Dense designs, multiple supplies, some high-speed | 3–4 weeks | Room for two routing layers plus clean references |
| 8–12+ | High-speed digital, RF front ends, SoM carriers | 4–6 weeks | Controlled impedance and stackup review mandatory |
If you are unsure which layer count your design needs, send us the schematic and a rough component list. Stackup recommendation is part of the quote, not a paid extra.
How we route for signal and power integrity
Most first-spin failures we are asked to rescue trace back to three things: a broken return path, inadequate decoupling, or a stackup that never had a defined impedance in the first place. Our routing process addresses each explicitly.
Reference-plane discipline
Every high-speed net is routed adjacent to an unbroken reference plane. Where a signal must change layers, we place stitching vias so the return current has a path that does not detour around a plane split.
Controlled impedance
Single-ended 50Ω and differential 90Ω/100Ω targets are calculated against the actual dielectric stack your fabricator will build, then handed to them as an impedance table in the fab notes — not left to chance.
Decoupling placement
Bypass capacitors are placed and via-connected before general routing begins, so the low-inductance path to the plane is never compromised by a trace added later.
Length matching where it matters
DDR, Ethernet, USB, and LVDS groups are matched to the tolerance the interface specification requires — and left alone where matching buys nothing.

Common questions
Can you do PCB layout from my existing schematic?
Yes — that is the most common engagement. We import your Altium or KiCad schematic, run a review pass to flag missing decoupling, footprint mismatches, or unconnected nets, then proceed to layout once you have signed off on the review findings.
Do you provide controlled impedance layouts?
Yes. We calculate trace geometry against your fabricator's actual dielectric stack and deliver an impedance table in the fabrication notes so the factory builds to the specified target rather than guessing.
How are revisions handled?
Revision scope is defined on each quote and agreed before work starts. Changes that alter the agreed scope are quoted separately rather than absorbed silently into the invoice.
