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

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.


We will be in Munich from November 13th to 16th, 2018 for ELECTRONICA fair
