Clean room ISO 8

éolane has a 700m2 ISO Class 8 Clean Room in Angers.

 Salle Blanche Iso 8

The ISO 8 room standard (or Class 100.000 according to the US standard) requires users to have a particular level of equipment to maintain, according to the ISO 14644-1 standard, a maximum of 29.3 particles of 5µm/m3.
It is a closed contamination environment where air quality (particle concentration), temperature, hygrometry and pressure are controlled and mastered.
It requires strict operating procedures and a high equipment level.
It guarantees that no significant particles (dust) will disturb the assembly of sensitive electronic components.

This room, which protects the production of sensitive microelectronic processes, meets IATF requirements.

This clean room allows:

Image Wafer

  • Miniaturization / Optimization
  • Performance Improvement
  • Thermal Dispersion
  • Parasite Reduction (Rf)
  • Power Consumption Reduction

It is organized in 4 areas (with individual traceability of components from the beginning of the manufacturing process):

  • Component transfer line - SMT
  • Microchip assembly line - Chip On Board
  • Integration line - BACK END
  • Hybrid and final TESTS area
