ESD in cleanrooms

Cleanrooms are among the most demanding environments for controlling electrostatic charge. As well as freedom from particles, ESD must also be strictly managed.

Where are cleanrooms used?

In semiconductor and display manufacturing, medical technology, optics and anywhere the highest cleanliness is required.

Why is ESD critical in a cleanroom?

A discharge also attracts particles and can instantly destroy highly sensitive structures – see what is ESD.

Special ESD equipment

Cleanroom-grade ESD clothing, gloves, shoes and dissipative floors of a suitable cleanroom class.

Air ionisation

Ionisers are indispensable, because many insulating plastics are used in a cleanroom.

Environmental control

Controlled humidity and regular measurements with measuring instruments keep the ESD risk low.

Standards

Besides ČSN EN 61340-5-1, cleanroom standards (ISO 14644) and industry-specific requirements apply.

Common mistakes

Unsuitable materials, missing ionisation and inadequate control.

Conclusion

In a cleanroom, cleanliness and ESD protection combine into one system. Find more guides in the ESD Guide.
