Hard Disk Drive

For manufacturers of hard disk drives, eliminating damaging contaminants is an essential part of the quality process. 3M filtration products help manufacturers of hard disk drives achieve high levels of process integrity for their critical applications for computer hard disk drives, server farms, data centers, and cloud storage.

Applications for Hard Disk Drives

For more than 100 years, 3M has developed innovative filtration and purification products by partnering with our customers and designing products to meet the exacting requirements of the hard disk drive manufacturing.

Ultrapure Water

Ultrapure water (UPW) is mainly used to remove defect-causing contaminants and to rinse or clean the substrates after the various processes.

3M’s filtration and gas transfer membrane products provide the required particle reduction and dissolved gas (O₂ & CO₂) reduction to meet the strict requirements needed for hard disk drive production.

3M’s filtration products provide superior flow characteristics while meeting the strict particle, TOC and resistivity requirements of electronics manufacturers.

Chemical Mechanical Polishing

Chemical mechanical polishing (CMP) is a process to level uneven areas by combining a chemical slurry of micro-abrasives with mechanical force provided by polishing.

3M has the CMP filtration solutions to allow hard disk drive manufacturers to help reduce micro scratches and defects and providing more process stability and reliability.

Plating Chemicals

Your plating solutions require stringent particle control to prevent defects and impurities in the deposited metal surface.

3M has particle control solutions to help remove particulate or contaminants and extend bath life to meet the needs for your electroplating process for process reliability and stability.

Wastewater

Manufacturing of hard disk drives requires large amounts of chemicals, which invariably generates large volumes of wastewater.

3M has particle control solutions to help remove or help reduce particulate/contaminants to extend bath life meeting your desired specifications.

3M™ Liqui-Cel™ Membrane Contactors are used in a variety of gas transfer applications to strip dissolved gases from aqueous fluids. In one specific use, ammonia gas is stripped from wastewater streams with a high concentration of ammonia, diffuses across the wall of a hollow fiber membrane, and is directly absorbed into a reactive acid solution.

This simultaneous removal and recovery of ammonia is possible in a single device. This process is called TMCS (Transmembrane Chemisorption).
