Capabilities

Everything a build needs, kept under one roof.

One partner from design to dispatch means fewer handoffs, tighter control and a single point of contact for your programme.

PCB Assembly

Surface-mount and through-hole assembly on a fully controlled line, from first prototypes to production runs.

01

PCB Fabrication

Bare-board fabrication to your Gerbers, single-sided through to complex multilayer stacks.

Prototyping & Quick-Turn

Full-turnkey prototypes with no minimum quantity, so you can iterate before you commit.

Schematic & PCB Layout Design

Design and engineering support that gets your board manufacturable, testable and right the first time.

Conformal Coating

Protective coatings for boards headed into harsh, humid or high-vibration environments.

Box Builds

Full enclosure assembly and system integration. Orders of any size, ready to deploy.

Cable Assembly

From custom cables to complex wire harnesses, built to your drawings.

Procurement

Component sourcing through established supply lines, managing cost, lead time and obsolescence.

A straight line from your files to your dock.

Send us your Gerbers and bill of materials. We handle the rest, and you keep one point of contact the whole way through.

  1. 01

    Quote & DFM review

    We price the build and flag anything that would bite in manufacture before it does.

  2. 02

    Procurement

    Components sourced and kitted through trusted supply lines, with lead times managed up front.

  3. 03

    Assembly

    SMT and through-hole populated on a controlled line by time-served technicians.

  4. 04

    Inspection & test

    Optical inspection and functional test, so what leaves the floor is proven, not assumed.

  5. 05

    Box build & ship

    Coated, enclosed, integrated and dispatched, ready to go straight into your product.
