Established in 2018 in accordance with the law for the freedom to choose one’s professional future, the gender equality index is a score that enables companies to assess the level of equality between men and women by 100 points, based on the following criteria:

  • Gender pay gap
  • Individual pay rise gap
  • The number of employees who received a pay rise upon their return from maternity leave
  • Parity among the top 10 earners

The minimal score expected is 75/100¹ and the official national averages improve from one year to the next :

87 for companies of more than 1 000 employees (83 in 2019) ;

85 for companies  of 250 to 1 000 employees (82 in 2019) ;

83 for companies of 250 to 1 000 employees

Indicated hereinbelow all of ELVIA PCB GROUP subsidiaries’ scores :

elvia Normandy – Coutances89
elvia Brittany – A&P Lithos93
elvia Loire Valley – CIRETEC85
elvia Fontainbleau – BREE94

« These good scores reward the actions carried out during 2020 in favour of gender equality and diversity strengthening in our facilities in compliance with our values »
Gaëlle BACHELOT, ELVIA PCB GROUP Head of Human Resources

As the European leader in Space PCB market with our DAS (Defence – Aero – Space) division, it is a logical consequence for ELVIA PCB GROUP, as well as a source of pride, to learn the qualification of its elvia Brittany – A&P Lithos facility by the European Space Agency (ESA) for its sculpted flex PCBs.

«This qualification is a continuation of what we do and master from nearly 15 years » Yannick Pedron, elvia Brittany – A&P Lithos Director.

It’s indeed a beautiful story of innovation and technological competence that unites the sculpted flex PCB technology to the know-how of our teams of Elvia Brittany – A&P Lithos to. They knew how to develop this power connection PCB technology more than 10 years ago to meet the space sector requirements with the CNES qualification and recognition. Today, it is again, the great reliability and the power capacity guaranteed by our sculpted flex PCBs that legitimately qualify us for ESA selected space programs such as launchers, satellites and many others prestigious and enthralling projects.

A qualification that illustrates ELVIA PCB GROUP’s strategy and determination to broaden its scope internationally.

With this ESA qualification, our sculpted flex expert is expanding its presence in the European and global market, driven by the export development strategy of ELVIA PCB GROUP.

The ESA qualification is a prerequisite to enter International Space market. It allows companies to demonstrate their capacity for adaptation to the requirements and the rigour imposed by this sector constantly improving.

The evidence being the small number of qualified companies that does not exceed 6. Among them, you can find two companies of elvia PCB Group : elvia Brittany – A&P Lithos, the only one qualified in sculpted flex and elvia Loire Valley – CIRETEC, accustomed to space program in ELVIA PCB GROUP for many years now.

After Mars InSight’s seismometer, SEIS, our talented teams in ELVIA LOIRE VALLEY – CIRETEC took part in the development of Perseverance Rover’s SuperCam.

Was there life on Mars?

NASA’s Perseverance rover landed on the Red Planet on February 18 to get some answers. And to write this new chapter of space exploration, NASA could count on France’s support and its technological skills to develop an essential tool: SuperCam, the very laser camera analyzing the organic and chemical composition of the surface of Mars.

Being a space and aeronautics expert, ELVIA LOIRE VALLEY – CIRETEC has been part of this adventure alongside the Laboratoire d’astrophysique de Bordeaux (LAB), the National Center for Scientific Research (CNRS) and the company Steel Électronique. Our expertise in printed circuit board, including multilayer HDI (High density Interconnect) PCB (Printed Circuit Boards), has been our strength to take up the technical and technological challenges that have arisen in this exploration. This is how we developed several of the SuperCam’s electronic mounts, which are currently used on Mars.

We worked on this French technological mission for 4 years, developing cutting-edge technology for the SuperCam. That being said, it was not a first for ELVIA LOIRE VALLEY – CIRETEC, since we also designed some printed circuit boards for the lander InSight’s (INterior exploration using Seismic Investigations, Geodesy and Heat Transport) seismometer SEIS (the Seismic Experiment for Interior Structure). That project has been on Mars since November 26, 2018, and measures the tectonic activity of the planet to deduce information like the size of its core or the thickness of its mantle.

Space and Mars remain full of mysteries for us to solve, and our teams are ready to tackle them.

This means we’ll see you soon for a follow-up on ELVIA PCB GROUP’s space adventure!


The only HITACHI UV/CO2 laser drilling in France is in elvia PCB

The only HITACHI UV/CO2 laser drilling in France is in elvia PCB!

Nowadays, High Density Interconnected PCBs can be manufactured thanks to the creation of µvias. Today, in France, there is just one equipment able to drill those specific vias with extreme accuracy and efficiency. It is called the HITACHI UV/CO2 laser drilling and it is in elvia PCB Group’s factory, in Coutances!

How does it work? The goal is to drill a small via (70 to 180 µm) between a layer N and a N-1. A UV laser source, which drills the top copper (generally between 9 and 17 µm thick), is associated with the CO2 laser source, which comes next to remove the dielectric without damaging the lower copper.

This equipement can be used for laser drilling, but also for cavities laser cleaning, thin layer cutting or flex cutting.

HITACHI UV/CO2 has specific characteristics. The holes minimum diameter enabled by this equipment is of 70 µm with a positioning accuracy of 10 µm. It has an automatic loader and unloader and can work with a maximum panel size of 630 x 530 x 7 mm. And the French exclusivity is that it uses UV (λ =355 nm) and CO2 (λ = 9400 nm) laser sources.


Elvia PCB Group is working non-stop to fight COVID-19

By Uncategorized No Comments

We’re working non-stop since the beginning of the current COVID-19 pandemic.


The health and safety of employees are, as always, the top priority. The necessary preventative measures were implemented quickly and efficiently and production is continuing in order to safeguard jobs and to ensure that we continue to support ours customers at this critical time.
Faced with the spread of the Coronavirus, a consortium of four major industrial groups has committed to manufacture 10,000 medical ventilators by mid-May.
We’re making a valuable contribution to this critical project by manufacturing the PCBs, a crucial part of the medical ventilators, in a record time.
Bruno Cassin, our Group’s President commented “Elvia is proud to be supporting this vital endeavour. We have succeeded today in delivering the first batch of 500 PCBs, which was manufactured in just 4 working days”.
Further production volumes are in preparation and even larger PCBs volumes are expected.

PCB Technology training

Designing a printed circuit board is not something that can be improvised and manufacturing it neither. All starts with a mutual recognition of the respective constraints.

Once again, employees from several THALES sites, from different business sectors, but whose common thread remains the electronic board, met at Elvia PCB for 2 days, to attend an initiation to the manufacture of printed circuits. The many stages involved in the manufacture of a printed circuit board were detailed, providing the necessary insights to make tomorrow’s designs even more successful.

We thank our partner, THALES group, and our colleague and co-leader, for trusting us for the organization of this 2019 session.
