PCB LAYOUT / ALTIUM DESIGNER / CLI SYSTEMS

Professional Altium PCB design, from schematic to fab.

We design and rescue printed circuit boards in Altium Designer — multilayer, rigid-flex, and high-speed work delivered as a complete manufacturing package. Existing project or blank canvas, we route it like it's going to production. Because it is.

Who we are

By professionals, for professional projects.

AltiumDeveloper is the PCB design practice of CLI Systems. We take on the boards that need to actually work in the field — not entry-level, not hacked together, not "close enough."

Bring us a brand-new design and we'll carry it from schematic capture through layout, verification, and a fabrication-ready package. Bring us an existing Altium project that stalled, needs a respin, or needs cleaning up, and we'll pick it up mid-stream and finish it right.

Either way you get real design files, sane libraries, and documentation your fab and assembly house can build from without a dozen back-and-forth emails.

What we do

Everything between the netlist and the finished board.

A full-stack design service. Whatever technology your product needs, it's a routing problem we've solved before.

CAP.01

New board design

Schematic capture, component libraries, placement, and layout for a design that starts as a blank sheet — built on a clean, maintainable Altium project.

CAP.02

Design rescue & respin

Inherited a stalled or messy Altium project? We pick it up mid-stream, resolve the DRC and library debt, run the ECOs, and get it back to buildable.

CAP.03

Multilayer & HDI

Controlled stackups, plane management, and high-density interconnect — blind and buried vias, microvias, and via-in-pad where the density calls for it.

CAP.04

Rigid-flex & flex

Dynamic and static bends, coverlay, stiffeners, and bend-aware routing for boards that have to fold into a real enclosure and survive it.

CAP.05

High-speed & SI

Controlled impedance, differential pairs, length and skew matching, return-path discipline, and EMI-aware layout for the signals that actually care.

CAP.06

Manufacturing packages

Gerber / ODB++ / IPC-2581, drill files, BOM, assembly drawings, pick-and-place, and a DFM review — a package your fab can build without guessing.

Selected work

Boards built for the field, not the bench.

PROJECT / EMBEDDED FLEX INTERFACE

Embeddable flex PCB

We helped a client develop a custom flex PCB to integrate into an existing system for voltage monitoring application — folded into the assembly working with the existing enclosure.

The board carries multiple bends, 0402 passives, and was designed for a 10,000-unit production run from the start.

CAPABILITY / DENSE ROUTING

High-density routing

Tight placement, poured planes, and disciplined routing on a densely packed board — analog kept clean, digital kept contained, and every net length-aware where it mattered.

PROJECT / MULTI-BOARD ASSEMBLY

Multi-board assembly

Several rigid boards designed to work as one system, joined by flex jumpers through board-to-board connectors — each board routed to its own mechanical envelope, with the interconnect planned so the stack folds together and builds cleanly every time.

How it works

A straight line from kickoff to a build package.

01 / SCOPE

Review & scope

We go through the netlist, constraints, stackup, and mechanical envelope, and agree on DFM targets before a single trace is drawn.

02 / LAYOUT

Place & route

Placement, plane strategy, controlled impedance, and length tuning — with checkpoints so you see the board take shape, not just the final file.

03 / VERIFY

Verify

Clean DRC, a DFM / DFA pass, and impedance and fabrication details confirmed against your chosen manufacturer's capabilities.

04 / HANDOFF

Handoff

You get the full manufacturing package plus the source Altium project — version-controlled, documented, and yours to keep.
