Electronic Circuit Design & PCB Services.
Prototype to Production Support for Electronics
Firmware/Embedded Development.

Proto Circuit Lab delivers end-to-end electronic design support — from concept to functional hardware. We specialize in circuit design, PCB layout, and prototype development, and help engineers, startups, and product teams move ideas into reliable products. Whether you need a fast prototype, board debugging, design optimization, or guidance for mass production, we provide practical, engineering-driven solutions.

With deep hands-on experience in schematic design, multilayer PCB layout, DFM/DFT, component selection, and manufacturing readiness, we ensure your product is engineered for performance, cost, and reliability. From early design reviews to factory coordination, Proto Circuit Lab supports every step with clarity and technical confidence.

What We Do

 

Schematic Design

Schematic design starts with defining the system architecture and partitioning the design into functional blocks. These blocks are translated into a detailed schematic that captures component selection, power distribution, signal interfaces, and protection circuits. Using professional CAD tools , the circuitry is structured into logical modules to verify signal flow, power integrity, and design correctness before proceeding to PCB layout.

PCB Layout Services

PCB layout translates the approved schematic into a manufacturable physical design. The process includes defining the layer stack-up, board outline, and component placement based on mechanical constraints and electrical requirements. During routing, signal integrity, controlled impedance, power distribution, grounding, and clearance rules are carefully evaluated to ensure reliable and safe operation. DFM and DFA checks are performed to minimize manufacturing risks, reduce design iterations, and improve first-pass build success.

Prototype Fabrication and Testing

Once the PCB layout is finalized, we generate complete manufacturing outputs including Gerber files, drill data, pick-and-place files, and assembly documentation for prototype builds. A 3D PCB model is created to verify mechanical fit, component clearance, and enclosure compatibility prior to fabrication. We work closely with the manufacturer to define build requirements, controlled-impedance parameters, and test expectations. After prototype fabrication, the boards are validated through in-house electrical checks and functional testing to confirm correct operation and design intent.

Transition to Mass Production

After the prototype is validated, we assist with the transition to volume manufacturing by preparing complete production documentation, including BOMs, fabrication and assembly notes, and revision control details. We support vendor onboarding by clarifying design requirements and manufacturing constraints, and help coordinate initial production runs. When required, we also define factory test strategies, including custom test jigs, firmware support, and validation procedures, to ensure consistent and repeatable testing of each PCB during production.

Sheet Metal Design Services (Electronics Enclosures)

We provide sheet metal enclosure design services for electronic assemblies, focusing on practical, manufacturable designs. Our work includes mechanical layout of PCBs within enclosures, mounting features, cut-outs for connectors and displays, ventilation considerations, and overall structural integrity. Designs are created with standard fabrication processes in mind, ensuring compatibility with laser cutting, bending, and assembly workflows.

Design services only — fabrication and manufacturing are not included. 

Windows Desktop GUI Development  (wxWidgets) 

We develop Windows desktop GUI applications using wxWidgets, primarily intended as user interfaces for embedded and electronic products. These applications typically serve as configuration tools, diagnostics utilities, data monitoring interfaces, and production or field-testing support software. Development is focused on stable, lightweight, and maintainable GUIs that integrate reliably with custom hardware and embedded communication protocols. 

 

3D Enclosure Design Services

We provide 3D enclosure design services using open source Freecad for electronic products, focusing on accurate mechanical integration with PCBs and internal components. Designs address board mounting, connector alignment, cable routing, ventilation, and assembly constraints. Enclosures are modeled to support common manufacturing processes such as sheet metal fabrication or CNC machining, with attention to functional fit and serviceability.
