Precision Cleaning for Hard Disk Drives

Precision cleaning solvents for hard disk drive components and media

A tiny speck of dust, a bit of cleaning solvent residue – even the smallest trace of a fingerprint – can lead to serious read/write errors or even disk failure.

As component sizes grow smaller and more complex, however, it becomes more difficult to get at and remove contaminants. At the same time, increased regulatory scrutiny and concerns about worker health and safety are restricting your available choices of cleaning solvents. All of which makes finding a practical cleaning solution more challenging than ever before.

Now 3M™ Novec™ Engineered Fluids give you an effective, sustainable way to meet the precision cleaning requirements of today's hard disk drive industry. Novec fluids are a family of nonflammable, non ozone-depleting, low global warming cleaning solvents that are highly effective for contaminant removal from many parts of the drive, including MR heads, HGAs, suspensions, as well as from disk media.

The low surface tension and low viscosity of Novec fluids allows greater penetration than conventional cleaning solvents, providing outstanding performance on both metallic and non-metallic parts – even in complex configurations and tight spaces, such as ABS areas. Their low heat of vaporization ensures rapid drying after the cleaning process. Novec fluids can be used in standard vapor degreasing equipment, immersion systems and in specialized cleaning machines with ultrasonic agitation.

  • Extremely low surface tension and viscosity, to penetrate and clean tight spaces
  • Non-corrosive and compatible with sensitive substrates
  • Can be used in many existing vapor degreasing and ultrasonic cleaning machines
  • Reduced emissive and drag-out losses
  • Cost-in-use comparable to other solvent and aqueous systems
  • Dries quickly and completely without oven drying, for fast throughput
  • Selective solvency
  • Low water solubility

Engineered for improved worker safety and reduced environmental impact

Novec fluids offer you an effective, sustainable solution that balances precision cleaning performance with outstanding safety and environmental properties.

  • Non ozone-depleting
  • Low global warming potential
  • Low in toxicity*
  • Nonflammable throughout the cleaning and drying process*
  • No hazardous air pollutants (HAPs) or n-propyl Bromide (nPB)

  • * See Material Safety Data Sheets for precautions and handling recommendations.

Novec fluids are not targeted for emission reduction by the Kyoto Protocol, and can provide a meaningful reduction of greenhouse gas emissions when compared to conventional cleaning solvents such as HFCs.

3M Novec Engineered Fluids for Precision Cleaning of Hard Disk Drive Components

The Novec fluids products listed below have been shown to be particularly suitable for critical disk drive cleaning applications. Products designated "DE", "DA" and "IPA" are azeotopic blends of Novec fluid with one or more organic solvents, and are typically used for medium to heavy-duty solvent cleaning of lubricants, fluxes and other soils.

Several high purity electronics grades of Novec fluids (designated as "DL") have been specially formulated for use in precision cleaning and lube deposition applications where extra high purity is required. Novec DL fluids offer even tighter specifications for ions, metals, particulate and non-volatile residue, and exhibit excellent solvency for disk lubes and additives. Specialized packaging helps to meet consistency and purity requirements.
