Quantum Circuit Technologies
An electronics engineering company focused on custom PCB design, embedded hardware, IoT systems and product development.
An electronics engineering company built around hardware
Quantum Circuit Technologies is an electronics engineering company focused on custom PCB design, embedded hardware, IoT systems and product development.
The company combines practical electronics engineering with modern embedded technologies to help transform concepts into functional prototypes and manufacturable products.
Work is organised around the engineering itself: understanding the requirement, choosing an architecture that fits it, designing the circuit and board, and proving the result on real hardware. Documentation is produced as part of the design, not after it — so a project that reaches prototype can move toward manufacturing without being rebuilt.
Engagements range from a focused review of an existing design to full ownership of the hardware development path. In every case the deliverable is an engineering package a manufacturer can build from.
- Custom PCB design
- Schematic capture and multilayer layout prepared against manufacturing constraints.
- Embedded hardware
- Microcontroller, wireless, sensor and power subsystems designed as one system.
- IoT systems
- Connected hardware with the connectivity, power and data path planned together.
- Product development
- Concept through prototype to a documented, manufacturable design.
Why Work With QCT?
Practical reasons rooted in how the engineering is done — not marketing claims.
Engineering First
Design decisions are driven by electrical performance, reliability, manufacturability and cost.
Production Mindset
PCB designs are prepared with manufacturing and assembly requirements in mind.
Complete Hardware Workflow
From schematic and PCB layout to BOM, Gerbers, CPL and prototype support.
Flexible Technology
We work across microcontrollers, sensors, wireless systems, power electronics and embedded hardware.
Direct Communication
Clear technical communication throughout the development process.
No inflated claims
We publish capability, not statistics. Project references, measured results and client details are shared directly during technical discussion where they are relevant.
Our Process
A predictable engineering sequence. Each stage produces something reviewable, so the design is validated before it moves forward.
- 01
Understand
We understand the product requirements, constraints and target application.
- 02
Architect
We select the appropriate components, interfaces, power architecture and system topology.
- 03
Design
We develop the schematic, PCB layout and supporting engineering documentation.
- 04
Prototype
The design is prepared for manufacturing and prototype assembly.
- 05
Validate
The prototype is tested, debugged and refined.
- 06
Manufacture
We prepare the final production package and support the transition toward manufacturing.
Technologies We Work With
Platforms, tools and interfaces we build with when a project calls for them. Technology is selected to fit the requirement — not the other way round.
