Question 1

What makes an electronic design safety-critical?

Accepted Answer

A safety-critical electronic design is one where failure could result in injury, loss of life, or significant environmental damage. These designs must adhere to rigorous standards such as DO-254 for aerospace, ISO 26262 for automotive, and IEC 62304 for medical devices. They require formal verification, redundancy analysis, and comprehensive documentation throughout the design lifecycle.

Question 2

How do you ensure EMC compliance in PCB designs?

Accepted Answer

We implement a first-principles approach to EMC compliance, starting with proper stack-up design and impedance control, strategic component placement to minimise coupling paths, careful power distribution network design, and pre-compliance simulation using signal integrity tools. Our designs are engineered to meet EN 55032, EN 55035, and MIL-STD-461 requirements from the outset, reducing the risk of costly re-spins.

Question 3

What industries do you serve?

Accepted Answer

Hian Technologies Ltd. serves aerospace, defence, automotive, medical devices, industrial automation, and other regulated industries where electronic reliability is paramount. Our clients include organisations such as Parker, ASML, Jaguar Land Rover, ProDrive, Protean Electric, Potenza, and TUMI Robotics.

Question 4

What is included in a Schematic Review?

Accepted Answer

Our Schematic Review (from £2,000) includes a comprehensive independent assessment of your electronic schematic covering circuit topology analysis, component selection validation, power integrity assessment, signal integrity considerations, safety and reliability analysis, compliance gap identification, and a detailed report with prioritised recommendations.

Question 5

What is included in a PCB Layout Review?

Accepted Answer

Our PCB Layout Review (from £2,500) covers stack-up assessment, impedance control verification, signal integrity analysis, EMC pre-compliance evaluation, thermal management review, DFM (Design for Manufacture) assessment, and a comprehensive report with actionable recommendations to reduce re-spin risk.

Question 6

How many projects do you take on at once?

Accepted Answer

We take on a maximum of three concurrent engagements. Availability is intentionally limited to protect engineering quality and ensure each client receives dedicated, senior-level attention throughout their project.

Question 7

Do you offer consultancy services outside the UK?

Accepted Answer

While we are based in Leicestershire, UK, we work with clients internationally. Our engineering consultancy services can be delivered remotely, with on-site visits arranged as needed for UK and European clients.

Question 8

What is the typical engagement process?

Accepted Answer

Our engagement follows a structured five-step process: 1) Discovery and NDA, 2) Risk mapping and requirements definition, 3) Design or independent review, 4) Verification gates and compliance alignment, and 5) Delivery and technical handover. This ensures rigorous quality at every stage.
