What we do

The Department of Electronics and Electrical Engineering integrates advanced competences in the design of electronic and electrical systems to deliver solutions tailored to client requests, with a focus on reliability and compliance with product-specific standards.

The department is organised into two specialist areas, each with a dedicated head and a team of specialised engineers, ensuring high professionalism, technical consistency and continuity throughout design and development.

The department works in close collaboration with the other teams, allowing us to turn ideas, needs and design constraints into concrete, optimised and industrialisable solutions. Compolab is an organisation that ensures effective integration between mechanics, electronics and software, transforming functional requirements and application constraints into reliable solutions.

Electronics area

The electronics area gathers competences for the design and development of embedded systems for various application areas (e.g. industrial, defence, medical…), working on hardware and firmware architectures of high technical complexity.

Design covers all the sub-sections needed for the operation of the electronic board within the system in which it is to be integrated: design and development of the power-management section (battery management and protection, switching regulators…), analog signal conditioning, routing of high-frequency digital signals, driver control, firmware design for acquisition and control.

Our method

A structured approach to managing technical complexity.

The Electronics and Electrical Engineering Department adopts a structured working method that allows the technical complexity of projects to be governed, ensuring consistency, quality and continuity throughout the entire development cycle.

1. Analysis of technical and regulatory requirements

Every project begins with an in-depth analysis of functional, performance and regulatory requirements. In this phase, the application context, operating conditions, safety constraints and reference standards are assessed, so that technically sound and compliant solutions can be established from the outset.

2. Design

The design is developed in a structured and progressive manner, defining architectures, schematics and technical solutions consistent with the initial requirements. The phased approach makes it possible to control design choices, reduce risks and maintain alignment among the various disciplines involved.

3. Firmware development and systems integration (where applicable)

When the project requires it, the method incorporates firmware development and hardware–software integration activities. This phase ensures correct interaction between system components, operational stability and compliance with the defined functional requirements.

4. Testing, validation and optimisation

The solutions developed undergo technical verifications and functional tests aimed at validating performance, safety and reliability.

Test results are used to optimise the design and reduce the risk of issues arising in subsequent phases.

5. Pre-compliance and certification support

The method includes pre-compliance activities and support for certification processes, with the aim of anticipating any non-conformities. This approach makes it possible to address the

certification phases more efficiently and in a more controlled manner.

6. Technical documentation and production support

The development cycle is completed with the drafting of structured technical documentation and with support for industrialisation and production phases. The documentation ensures traceability of design choices and technical continuity over time.

Mission

The mission of the Department of Electronics and Electrical Engineering is to develop reliable, safe and compliant electronic and electrical systems capable of effectively responding to complex application requirements and demanding industrial contexts. Through a structured method and specialist competences, working transparently and continuously with the Client, the Department turns technical needs into solid industrial solutions, ready for industrialisation and the market.

One department, two specialised teams with distinct competences, united by a common goal: to deliver robust, reliable systems ready for industry, from design to construction.
