Low-particle couplings and screws in stainless steel, titanium and aluminium, ultrasonically cleaned and cleanroom-packaged for semiconductor, pharma and medical production.

Cleanroom

Overview

Components for cleanroom environments

In cleanroom production, materials with low-to-zero particle generation are essential. Preferred materials are stainless steel, titanium and aluminium; black-oxide coatings are not allowed because they can shed particles. NBK cleanroom couplings and screws are ultrasonically or IPA-cleaned in a cleanroom and then packaged, so they arrive ready to install without adding contamination.

These components are ideal for semiconductor equipment, pharmaceutical machinery and medical and life-science devices, as well as food machinery. NBK offers a dedicated cleanroom washing and packaging service (wash room ISO Class 7, packing ISO Class 4) with ultrasonic or IPA methods and post-cleaning particle measurement. Full specifications and CAD files are on nbk1560.com.

Frequently asked questions

What is included in the cleanroom wash and packing service?

Parts are cleaned and packed in a cleanroom (wash room ISO Class 7, packing ISO Class 4) using either ultrasonic cleaning (suffix USC) or IPA cleaning (suffix IPA), followed by particle measurement. It is used for FPD, semiconductor, medical and food components.

Why is black oxide not allowed in cleanrooms?

Black-oxide coatings can shed particles, which contaminate a cleanroom. NBK therefore supplies cleanroom parts in stainless steel, titanium and aluminium, cleaned and packaged to avoid adding particles.
