Filters for CMP slurries, ultrapure water, and cleaning chemicals used in electroplating applications are available. We have membrane filtering alternatives that can remove pollutants to the level greatly desired by data makers, whether it's during the initial galvanizing process or the final nickel plating. Alfa Chemistry data storage filters improve key process performance by removing impurities and lowering catastrophic flaws.
CMP slurries, ultrapure water, and cleaning chemicals used in electroplating applications can all be filtered with our filter solutions. We have membrane filtering alternatives that can remove pollutants to the level needed by data producers, whether it's during the initial galvanizing process or the final nickel plating. By removing pollutants and limiting catastrophic faults, Alfa Chemistry data storage filters improve the operation of crucial processes.
CMP Filtration
Our CMP filters are engineered to improve process performance by managing the shape, size, and concentration of slurry particles, resulting in higher yields and fewer defects. The particle size, shape, and density of the large particle count (LPC) slurry can be regulated to the given process parameters using filter design. To accomplish built-in pre-filtration and long service life, the CMP filter has a constantly distributed pore structure.
Benefits:
- Enhanced process control and stability
- Improve regional/process efficiency
- Extend mud life
- Reduce micro scratches
Electroplating Filtration
The adoption of an efficient filtration system can help to maintain the process and plating rate stable, as well as prevent downtime caused by the plating tank's offset. On nickel-plated substrates, effective filtration can eliminate flaws. The aluminum substrate is protected by our electroplating filter, which also aids in the proper control of the electroplating process. For the nickel plating process, we provide a choice of film solutions that guarantee high removal retention.
Benefits:
- Enhanced process control and stability
- Extend chemical/bath life
- Reduce common defects
Wet Etching Clean Filtration
Our wet etch cleaning filter removes faults from glass and aluminum substrates while also extending the filter life, lowering the cost of each disk. The advanced wet etch clean filter achieves sub-micron filtering at a very low-pressure drop, allowing for excellent particle retention without losing flow rate and thereby enhancing bath cleanliness. They can be customized and prevent particles from accessing the hard drive's surface.
Benefits:
- Enhance process stability
- Extend chemical life
- Reduce hard drive defects
