1st place in the Occupational Health and Safety Award

The Occupational Safety Award Baden-Württemberg honours small and medium-sized companies that are committed to maintaining the health of their employees.
For the first time, Labour Minister Dr. Nicole Hoffmeister-Kraut awarded small and medium-sized enterprises in Baden-Württemberg with the NOBIS-Occupational Health and Safety Award . "Making our working environment safe and healthy is central to maintaining the well-being of employees, their performance and satisfaction. The attractiveness of a workplace also depends on this. Baden-Württemberg will only be able to maintain its leading position as one of the most successful economic regions in the world if we maintain the earning capacity of employees into old age," said the initiator of the award at the online award ceremony.

Our winning idea: A warehouse guidance system

Due to the constantly growing range of products, the complexity of our warehouse requirements and occupational safety measures is also increasing. In order to guide our employees through the confusing "jungle" of hazard classes, we have developed an intuitive colour-coded warehouse guidance system. Deliberate simplification and a visual division of our warehouse sections into different coloured categories is intended to ensure that our employees can recognise hazards at any time without prior technical knowledge and take appropriate protective measures in an emergency. Furthermore, the colours provide information on which products may be stored together and where a suitable storage space for the corresponding chemical is located. This procedure has the added advantage that every pallet space is used optimally and without further risk.

! AZ 520 D phase out !

The manufacturer Merck informed us that the protective coating AZ 520 D will be phased out no later than end of 2021 (official statement).
Basically, the AZ 520 D is a photoresist without photoactive compound, which should make it comparable easy to find a suited alternative. We would be glad if you contact us to discuss your requirements on a protective coating, and assist in finding another resist from our portfolio, which could either be a standard low-cost photoresist, or another PAC-free resist.

We are very sorry about this decision from the manufacturer, and will do our best to allow you a smooth transfer to an alternative resist.

! AZ 5214E phase out !

The manufacturer Merck informed us, that the photoresist AZ 5214E will be phased out until end of 2021 (official statemant). We also have been informed, that a similar (but not identical) product is already on the market: The Japanese version of the AZ 5214E.

In order to assist you for qualification of the Japanese AZ 5214E, we will be able to provide samples of this resist in near future (probably February/March 2021) as well as technical support in process parameter optimization.

Please feel free to contact us!

For some years now, NMP has been classified as toxic to reproduction and the use of NMP has become more and more restricted. Now the EU has continued to restrict the use of NMP, so that after 09.05.2020, NMP can only be used if special precautions are taken.

Technic France, our current single supplier for NMP, has now decided to completely stop the production of the NMP.

We have many products in our portfolio that can replace NMP and many customers have already qualified alternatives in the past due to the increasingly problematic situation regarding NMP. DMSO, TechniStrip D350, NI555, P1316, P1331, MLO-07, Micro D2, AZ 100 Remover or the strippers from Intelligent-Fluids SH5 and SVD can be considered as alternative products.

We would be happy to supply you with samples of possible alternatives; it is best to briefly describe the process and the (substrate) materials involved so that we can explore the best alternatives together with you.

! AZ MIR 701 product change !

The manufacturer of the resist AZ 701 MIR (14 and 29 cPs) informed us on a scheduled product change notification concerning a PFOA related ingredient (PCN).

As the qualification document (each one for both viscosities) shows, the PFOA-free AZ 701 MIR does not reveal significant changes compared to the PFOA-containing AZ 701 MIR.

If you would like to test or qualify the PFOA-free AZ 701 MIR, we will be able to provide samples.

Please feel free to contact us!

DMSO from MicroChemicals

In addition to our solvents acetone and isopropyl alcohol, we are now offering our new MicroChemicals DMSO in ULSI quality. The solvent and stripper is available in 2.5 L containers and can be ordered as single bottles or in the packaging unit of 4 x 2.5 L.

Due to its low vapor pressure and its water solubility, DMSO is an excellent stripper for resists respectively Lift-off media and is a non-toxic substitute for the NMP, which has been classified as toxic since a while. The optional addition of cyclopentanone or MEK increases the performance of the stripper for certain
applications and significantly lowers the melting point of pure DMSO.

If you are interested in a sample of our DMSO, please let us know.

Our new Strippers

Photoresist Stripper SVD and SH5

The strippers easily removes layers of photoresists (PR) from inorganic substrates such as silicon, glass and metals (e.g. copper). The smart intelligent fluids® (IF) mode of action is not based on aggressive dissolving processes as in the case of many conventional products. Instead, intelligent fluids® enable a gentle physical detaching even of persistent layers, without damaging the substrate surface.
