Foamtec Face Masks for Cleanroom

Foamtec’s cleanroom foam face masks are widely employed as under masks in cleanrooms that use headcovers with built-in face masks.

Foamtec’s Foam face masks are not impacted by recently implemented export or import restrictions, so are a more readily obtained mask for semiconductor, pharmaceutical, aerospace and medical device cleanrooms.

Most importantly, the use of Foamtec’s foam face masks does not take supply away from hospitals and medical clinics treating the Corona Virus.

While foam face masks do not have filtration capabilities against viable particulates, the table below demonstrates the low particle counts vs. three-ply non-woven masks. As an added benefit, foam face masks significantly reduce the fogging of safety glasses, primarily when employed as under mask.

S3 Alliance installed and grounded a Wafer Transfer Unit from Mactronix

Last year S3 Alliance installed and grounded a Wafer Transfer Unit from Mactronix to a Manufacturer of electronic devices in Germany.  The Maintenance Engineer said: 

“Our PVA-TePla Wafer Transfer Units from Mactronix showed increased static load during transfer of ~3KV as measured. The solution offered by Mactronix was to replace the original Ultem combs with new, ESD-compatible PEEK ones. After installing and grounding them (S3-Alliance service available), the measured static load was reduced to <50V!

This solution is simple and very efficient and because the new comb’s pricing is similar to the original combs, also the most price-worthy option to get rid of ESD problems with batch transfer systems in general.”
