Electronic Prototyping & Prototype Development

Circad provides electronic prototyping to help businesses turn product concepts into tested, practical electronic designs.

Prototyping allows us to prove key design principles, test hardware and firmware together and identify potential problems before committing to production.

Depending on the maturity of the product, we can develop anything from a simple proof of concept through engineering prototypes to production-representative electronics.

Our electronic design and manufacturing teams work together throughout this process, allowing designs to be refined quickly and prepared for reliable manufacture.

Proof-of-Concept Electronics

At the earliest stage of development, the objective is often to prove that the fundamental product concept is technically achievable without investing unnecessarily in a complete custom design.

A proof-of-concept prototype may use an electronic development platform such as Arduino or Raspberry Pi, together with additional circuitry, sensors or communications hardware.

This allows important questions to be answered early:

Does the proposed technology work?

Can the required performance be achieved?

Are the chosen sensors, processors or communications technologies suitable?

Are there technical limitations that need to be addressed before further development?

Once the concept has been demonstrated, development can progress towards a custom electronic design.

Engineering Electronics Prototypes

An engineering prototype moves the project beyond proof of concept and towards the intended finished product.

At this stage, Circad can develop custom electronics that more closely reflect the required functionality, physical dimensions and operating environment of the final design.

Once the required product form and dimensions have been agreed, we can establish the available space and locations for embedded electronics, connectors, sensors and electro-mechanical devices.

The resulting electronics prototypes can then be used to:

verify circuit performance

test hardware and firmware integration

assess thermal behaviour

confirm mechanical integration

validate communications and interfaces

identify changes before pre-production.

Simulation and physical testing are used throughout development to ensure that the design meets the agreed functional and performance requirements.

Testing and Refining Prototype Electronics

Effective electronic prototyping is an iterative process.

Testing frequently identifies opportunities to improve performance, reliability, manufacturability or cost. These findings can then be incorporated into the next design iteration before further prototypes are produced.

Depending on the application, testing may include:

electrical and functional testing

firmware validation

communications testing

thermal assessment

power-consumption testing

environmental evaluation

compliance pre-testing.

Because Circad combines electronic design and prototype capability, findings from testing can be fed directly back into the engineering process rather than managed between separate suppliers.

Pre-Production Prototypes

Once functionality and performance have been confirmed, pre-production prototypes provide an important bridge between product development and manufacture.

These prototypes allow the design to be evaluated using components, assembly methods and processes that increasingly reflect eventual production.

They also provide an opportunity to optimise:

assembly procedures

manufacturing documentation

work instructions

inspection requirements

functional testing

programming procedures

realistic manufacturing time and cost.

This provides valuable evidence that the design is not only functional, but capable of being manufactured reliably and economically.

From Electronic Prototype to PCB Manufacture

Once the design has been validated, the next stage is to confirm that it can be manufactured and assembled consistently.

Our Ipswich facilities include manual and automated manufacture covering PCB assembly, electrical and mechanical assembly, wiring harnesses, device programming and functional testing.

Where a project has reached the stage at which physical PCB manufacture rather than further development is required, our prototype manufacturing services provide the next step towards production.

Why Choose Circad for Electronic Prototyping?

Circad combines design, software development, prototype manufacture and testing within one engineering team.

This means prototype development can be considered as part of the complete route to manufacture rather than as an isolated activity.

Our prototyping capabilities include:

proof-of-concept development

circuit design

embedded hardware and firmware

PCB design

engineering prototypes

prototype manufacture and assembly

functional testing

pre-production prototypes

design refinement for manufacture.

This integrated approach helps identify technical and manufacturing risks earlier and reduces the number of handovers between design and production.
