Sub-micron particle control
Yield-limiting defects come from particles well below 0.5 µm, which conventional filtration does not address at all.
Advanced Manufacturing · Industry
Ultrapure water, process chemical and cleanroom air filtration for PCB, display and component manufacturing.
- UPW polishing rating
- 0.05 µm
- TOC contribution
- < 1 ppb
- Cleanroom class supported
- ISO 5
The constraint
Particle counts measured in single digits.
Electronics manufacturing operates at a scale where the contaminant is smaller than anything visible. A particle that would be irrelevant in any other industry is a short circuit here.
Standards we work to
- ISO 14644
- SEMI F57
- ASTM D5127
- IEST-RP-CC001
- EN 1822
TOC and ionic contribution
The filter itself must not contribute organic or ionic load to ultrapure water systems.
Chemical aggression
Etchants, strippers and solvents demand PTFE and PFA flow paths across the full process chemical inventory.
Continuous recirculation
UPW loops run permanently, so pressure drop is a continuous energy cost as well as a hydraulic constraint.
