Laboratory for technical cleanliness, cleanroom class 8

Technical Cleanliness Verification

Residual dirt analysis for industry

Accredited test laboratory for
technical cleanliness verification

In our excellently equipped cleanliness laboratory we acquire, extract and analyse particulate contamination and filmic contamination. We undertake for you the check on the surface cleanliness of very small function-related components, entire assemblies and systems up to 1,000 kg, as well as a very wide range of fluids. We also support you with particle monitoring in your production and assembly environment.

Harmful particles

Correlative particle analysis:
know more sooner

We combine various microscopy and spectroscopy methods to acquire harmful particles reliably. As such, along with reflected light microscopy, we use also SEM-EDX analysis and RAMAN & FTIR spectroscopy. In this way we can clearly identify organic and inorganic particles in relation to their material and the damage the particles can cause.

Your advantage: you receive detailed, comprehensive results for organic and inorganic particles.

In your test report you receive detailed information about:

  • Quantity and size class: from 5 μm
  • Material classes & composition: metals, minerals, salts, organics
  • Damage behaviour: hardness class, conductivity, magnetism

Fast, reliable
cleanliness inspections

  • Acquisition, extraction and analysis of particulate and filmic contamination
  • Correlative particle analysis using light and electron microscopy, as well as RAMAN and FTIR spectroscopy
  • Verifiable types of particles: metals, minerals, salts, organics, fibres
  • Analyses according to VDA 19/19.1/19.2, ISO 16232 as well as customer standards and specifications
  • Class 8 cleanroom
  • Qualitative and quantitative investigation of filmic and ionic residues
  • Particle monitoring and analysis of particle traps for environmental monitoring

Quality advantage due to technical cleanliness verification

Technical cleanliness verification is an important quality feature these days, among others in the automotive industry, the supplier industry, medical technology, the electrical engineering industry and the new sector of e-mobility. Huge technical advances mean that consistent compliance with cleanliness requirements is no longer just a voluntary exercise, instead it has become mandatory. Our accredited laboratory and our multi-faceted cleanliness analyses help you as a manufacturer to guarantee the function, durability and quality, as well as the trouble-free manufacture of your products.

Applications for technical cleanliness verification

These days, no branch of modern industry can afford to fail to comply with cleanliness limits. Technical cleanliness verification guarantees both the checking of prototypes as well as the quality of ongoing production processes.

Automotive

Both conventionally powered vehicles and electric vehicles have function-related parts inside pipes, pumps, valves or similar components. Fluids can transport existing particles to susceptible areas and in this way cause the long-term impairment of functionality. During residual dirt analysis we detect these particles and analyse the damage they can cause.

Medical technology

Along with safeguarding cleanroom compatibility, technical cleanliness verification for medical technology is also used to make possible trouble-free operation. In practice, production-related particulate contamination represents an obstacle if, for example, material residue is left behind during milling. A thorough residual dirt analysis is the method of choice for verifying the removal of this residue in a subsequent washing process.

Electronics manufacturing

The assurance of technical cleanliness is of major importance during the manufacture of electronic assemblies. Even minor contamination can cause major economic damage. For this reason ensuring a clean assembly and production environment is extremely important. Foreign particles, if they are not embedded or fixed on printed circuit boards, can reduce the minimum electrical distance and drastically increase the risk of failure due to leakage currents, or even electrical breakdown. Solder pastes, flux residues or adhesives used during the manufacture of printed circuit boards can shorten leakage paths and hinder the wettability or solderability.

Frequently asked questions

What is the significance of iso 16232 and vda 19.1 for technical cleanliness verification?

ISO 16323 and VDA 19.1 (formerly VDA 19) are standards that specify the requirements on the use and documentation of the determination of particle contamination on components for the automotive industry. VDA 19.1 is a German standard for which ISO 16232 is the international counterpart.

Which components can be analysed at quality analysis?

In our laboratories we are able to analyse and determine the technical cleanliness of both very small function-related components with a size of a few millimetres, as well as entire assemblies and systems with a weight of up to 1,000 kilograms. We would be pleased to provide you with specific advice on this topic.
