Engineering capabilities

From Circuit to Product

Hardware development is a chain of dependent decisions. A component chosen at architecture stage constrains the layout; a layout choice constrains what can be assembled.

Quantum Circuit Technologies can support a project across the full chain or join at the stage where support is needed — reviewing an existing schematic, taking a proven prototype toward manufacturing, or starting from a blank page.

  1. 01

    Concept

    Requirements, constraints, target application and feasibility.

  2. 02

    System Architecture

    Block diagram, component selection, interfaces and power topology.

  3. 03

    Schematic

    Circuit design, pin planning, review and design rule definition.

  4. 04

    PCB Layout

    Stack-up, placement, routing, grounding and DRC verification.

  5. 05

    Prototype

    Fabrication and assembly documentation, build and bring-up.

  6. 06

    Testing

    Measurement, debugging, refinement and design iteration.

  7. 07

    Manufacturing

    Production package, DFM review and transition to manufacturing.

How we work

Our Process

A predictable engineering sequence. Each stage produces something reviewable, so the design is validated before it moves forward.

  1. 01

    Understand

    We understand the product requirements, constraints and target application.

  2. 02

    Architect

    We select the appropriate components, interfaces, power architecture and system topology.

  3. 03

    Design

    We develop the schematic, PCB layout and supporting engineering documentation.

  4. 04

    Prototype

    The design is prepared for manufacturing and prototype assembly.

  5. 05

    Validate

    The prototype is tested, debugged and refined.

  6. 06

    Manufacture

    We prepare the final production package and support the transition toward manufacturing.

Product design flow

From Schematic to Finished Product

Every stage of hardware development produces something tangible. This is what gets designed, and what you receive at each step.

Schematic Design

The circuit itself — component selection, pin planning, power rails and interfaces, drawn as a reviewable sheet with reference designators and net labels.

  • Source project
  • Design notes

PCB Layout

Stack-up, placement and routing — controlled return paths, sensible grounding and a board outline that fits the mechanics it has to live in.

  • Layout files
  • Gerbers
  • Drill files
  • DRC report

BOM & CPL

The bill of materials with part numbers and packages, plus the component placement list — the two files an assembler needs before a board can be built.

  • BOM (CSV)
  • CPL / pick-and-place
  • Sourcing notes

Manufacturing

The design prepared for the factory floor — stencil and paste data, assembly drawings and the checks that catch problems before they are etched into copper.

  • Fabrication package
  • Assembly drawings
  • Stencil data

Finished Product

The assembled unit, tested and fitted to its enclosure — the point where a schematic becomes something you can hold, ship and sell.

  • Assembled hardware
  • Test results
  • Production package
