At Quantum Controls, Inc., we specialize in the design and development of custom printed circuit board assemblies (PCBAs) and embedded software that power innovative products across industries. Our development process combines engineering precision with a commitment to quality, ensuring every solution meets rigorous technical standards and client expectations.
Below is an overview of our structured development approach, from concept to production, that drives reliability and results.
1. From Vision to Feasibility
Every successful project begins with understanding.
We start with in-depth client consultations to define functional requirements, technical specifications, and timelines. Once objectives are clear, our engineers create a comprehensive requirements document outlining key details, including PCB size, power needs, communication interfaces (I²C, SPI, UART), and microcontroller selection.
A feasibility assessment follows to evaluate component availability, cost, and technical risk. Nothing proceeds without mutual agreement, ensuring alignment before design work begins.
2. PCB Design Excellence
Our hardware design team transforms requirements into a tangible solution using Altium Designer.
The process includes:
- Schematic Design: Capturing every electrical connection with precision.
- Component Selection: Choosing reliable, readily available parts and maintaining a detailed Bill of Materials (BOM).
- PCB Layout: Optimizing signal integrity, power distribution, and thermal performance, verified through comprehensive Design Rule Checks (DRC).
- Prototype Fabrication: Partnering with trusted fabrication houses for high-quality prototypes ready for real-world evaluation.
3. Embedded Software Development
Our embedded systems engineers craft the firmware that brings the hardware to life.
- Architecture Design: Defining system modules and interfaces based on performance and functionality goals.
- Implementation: Writing efficient, maintainable code in C, adhering to Quantum Controls’ internal coding standards.
- Integration and Testing: Testing each module independently, then integrating on the actual hardware platform.
- Documentation: Providing thorough, well-commented code for transparency, maintainability, and future scalability.
4. Testing, Validation, and Client Collaboration
Before any design reaches production, it undergoes rigorous testing and validation.
- PCB Testing: Electrical and functional validation ensures every board performs as designed.
- Firmware Testing: Includes unit, integration, and system-level testing — often conducted on near-production hardware.
- Client Feedback: Results and findings are reviewed collaboratively, with refinements made as necessary to achieve full satisfaction.
5. From Prototype to Production
Once validated, we move toward full-scale production with precision and transparency.
- Final Documentation: Complete design packages include source code, design files, BOM, and test reports.
- Handover and Field Testing: Clients receive all deliverables and may conduct additional real-world testing.
- Production Release: Upon approval, final files are transferred to our in-house manufacturing team.
- Post-Release Support: Our engineers remain available for continued support and optimization.
6. Quality Assurance and Document Control
Quality is more than a phase, it’s part of our culture.
We conduct regular internal and external audits to verify compliance with our documented procedures. Any nonconformities trigger corrective action plans, ensuring continuous improvement.
All project files are maintained in a centralized repository with version control (SVN), ensuring full traceability, accountability, and change management throughout the product lifecycle.
The Quantum Controls Advantage
By combining structured engineering methodology with hands-on expertise, Quantum Controls delivers PCBAs and embedded systems that are not only functional but built for long-term performance and reliability.
Whether you need concept-to-production design or firmware integration, our team ensures your product is developed right the first time, efficiently, transparently, and to the highest standard.
