What we build

One partner from first prototype to production run.

Pick the board you need. Every service shares the same DFM review, the same inspection and one point of contact.

Prototype PCBs

Quick-turn 1–2 layer and multilayer boards for bring-up, testing and design iteration.

  • — Quantities from 5 pcs
  • — FR-4, 0.4–2.0 mm
  • — Engineer DFM check on every order

Multilayer & Impedance Control

4 to 32 layer stack-ups with controlled impedance for high-speed and dense digital designs.

  • — ±10% impedance (±5% on request)
  • — Via-in-pad, epoxy or copper filled
  • — Backdrill on 4+ layers

Aluminium & Copper Core

Single-layer metal-core boards that move heat away from LEDs, drivers and power stages.

  • — Aluminium-core MCPCB
  • — Copper core with direct thermal pads
  • — Up to 602 × 506 mm

RF & High-Frequency

Rogers and PTFE laminates for antennas, radar front-ends and low-loss signal paths.

  • — 2-layer Rogers / PTFE
  • — 1 oz finished copper
  • — Stable Dk across frequency

PCB Assembly (PCBA)

SMT and through-hole assembly with sourced or consigned parts, inspected before it ships.

  • — Single or double-sided SMT
  • — Turnkey or consigned parts
  • — AOI and X-ray for BGA

Design & DFM Support

Schematic-to-layout support and a manufacturability review before anything is built.

  • — Layout from schematic
  • — Stack-up and impedance planning
  • — Panelization for assembly
Mask & finish

Seven mask colours, four finishes. Try them on.

Choose the look and the solderability your product needs. Mask colour doesn't change the price on standard FR-4.

How ordering works

Six steps, and you approve before we build.

01

Upload files

Send Gerbers, drill data and, for assembly, a BOM and pick-and-place file.

02

DFM review

An engineer checks your data against the capability sheet and flags anything that would fail.

03

Quote and approve

You receive a line-item quote with lead time. Production starts only after your approval.

04

Fabrication

Imaging, etching, lamination, drilling, plating, mask, finish and electrical test.

05

Assembly and inspection

Parts placed and soldered, then checked with AOI, X-ray where needed, and visual QC.

06

Pack and ship

Vacuum-sealed with desiccant and shipped with tracking, plus the inspection report.

Hands assembling electronic components on a board
PCB assembly

Boards that arrive populated, inspected and ready to power up.

Send a BOM and placement file with your Gerbers. We source parts or use yours, place and solder them, and inspect every board before it ships.

  • 0201 passives and 0.4 mm BGA
  • Turnkey or consigned parts
  • Single and double-sided SMT
  • Programming and functional test
Assembly details
Quality

Checked by people and machines at every stage.

A person reviews your files

Every order gets an engineer DFM check against the capability sheet. Problems are raised with you, never silently "fixed".

Electrical test on bare boards

Opens and shorts are tested before boards leave fabrication, so faults are caught before parts are placed on them.

AOI and X-ray on assembly

Automated optical inspection on every assembled board, with X-ray for BGA and bottom-terminated packages.

Your design stays yours

Files are used only to build your order. We sign NDAs before you send anything if you need one.

FAQ

Questions before you order?

All questions
What do I need to send for a quote?

A zipped set of Gerber files with the drill file is enough for bare boards. For assembly, add a BOM with manufacturer part numbers and a pick-and-place file. Tell us the quantity and anything non-standard, such as impedance control or a special finish.

What is the minimum order quantity?

Bare boards start at 5 pieces, and assembly starts at 2 boards. There is no upper limit; pricing per board drops as quantity rises.

How quickly will I get a quote?

Most requests are quoted within one business day. Assembly quotes with many unique parts can take a little longer while we check component availability.

Is my design kept confidential?

Yes. Files are used only to quote and build your order, are never shared outside the production team, and we are happy to sign an NDA before you send anything.

What layer counts and materials do you support?

FR-4 from 1 to 32 layers, single-layer aluminium and copper-core boards, and 2-layer Rogers and PTFE for RF. The full list of limits is on the capabilities page.

Can you build controlled-impedance boards?

Yes, on 4 layers and above with ±10% tolerance as standard and ±5% on request. Send your target impedances and we will propose a stack-up and trace geometry.
