Clean room and laboratory in Switzerland

"The precision of a reading head can be compared with a Boeing 747 flying over earth surface less than 1 cm from the ground, with a speed of 272 km per second and able to count every single blade of grass."

Our swiss laboratory

Our laboratory is adjacent to our administrative offices. The access to this laboratory is secure with a swipe card locking system that allows only a few permitted persons to enter. It also offers a traceability for each entrance and exit.

Our laboratory is divided in different specific zones (soldering, disassembly, recovery, clean room, etc.).

A secure and quality laboratory is a success factor.

Our swiss clean room


We have our own clean room in Neuchâtel - Switzerland - (in a separate room of our laboratory) of 12m2 ISO 5 certified.

This clean room is under overpressure and inside, there's a laminar flow hood ISO 3 certified.

This in the laminar flow hood that we proceed to the manipulations that require a absolute cleanness, as, for example, changing the head stack or cleaning the platters.

Why we work in a clean room ?

The constant evolution of technologies and the miniaturization of the HDDs force us to use leading-edge technologies, so we can maximize a data recovery success chances.

Indeed, the detail of a platter surface is so small, that a single speck of dust could irreparably damage this surface.

Miniaturization and density of the HDDs

The detail of a platter surface is so small, that the informations density per cm2 is extremely high. Here are some examples of density on actual HDDs.

Distance between a reading head and the surface

A read/write head's size is close to 12 nanometers, or 0.000012 millimeters. The platters, that are spinning very fast, create a 250km/h draught on the platters surface. This allows the reading heads to fly over the surface, thanks to the bearing capacity.

The least unevenness on the platter will damage the reading irreparably, then the rest of the surface will be damaged because of the domino effect.
