NanoProof 1.0 PCB Waterproofing Surface Treatment

Harmonization Code : 2901.10.00.00 |   Acyclic hydrocarbons; Saturated
Main features
  • Provides basic protection for accidental water damage
  • 10-100 nm thickness
  • IPX3

Product Description

NanoProof 1.0 is a nanoscale surface treatment designed to impart hydrophobicity and reduced friction to circuit boards and electronic components. It is a simple, one-step process that provides basic protection for accidental liquid contact, IPX3

NanoProof 1.0 is safe to use, and the dried film is PFAs free, nontoxic, nonflammable, and nonconductive. The treatment can adhere to a broad range of substrates and does not change the appearance of the surface (100% Visible light transmission) at <20 nm thickness. 

Advantages of Aculon's NanoProof 1.0

 

  • IPX3
  • Very forgiving in application / reworkable
  • Extremely flexible
  • No cure required
  • Handleable when dry
  • Contains UV tracer
  • RoHS and REACH compliant
  • PFAs Free


Utilization of multiple options
Please note that many customers have found significant success utilizing two or more of the available NanoProof® technologies. Often times the most sensitive components benefit from the most robust NanoProof® technology (5.1) while the remaining components can be coated with the less robust coatings to benefit from their electrical push-through capability, flexible nature, and lower costs.

 

Detection/Inspection

All NanoProof products contain a UV Tracer which is visible under 365nm wavelength UV light (Detectable by both the human eye and automated detection systems). Please note that solder masks and other substrate materials containing a UV tracer may make accurate detection of NanoProof difficult.

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 25°C 24 days
Physical Properties
Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in

Flash Point
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor.

Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.

How to apply NanoProof 1.0

STEP 1  CLEAN

STEP 2  TREAT

STEP 3  DRY

Parts must be sufficiently clean before treatment for proper bonding and effective application. This can be accomplished by first degreasing the surface with solvents/rinsing with IPA.

Dip - Fully immerse the part in the treatment solution for 1 minute. Withdraw the part at a steady rate to ensure even coverage. Allow to air dry.

 

To dry, the part should be placed at room temperature until the solvent is evaporated. It should leave an oily coating that is deformable to the touch. In some cases, additional thermal treatment (e.g. 100C for 5 minutes) will speed solvent evaporation.

 

 

Spray - Spray the solution on the substrate, air dry. If the coating is too thick, reduce the amount applied by changing the settings on the spray gun or using a diluent.

Dispense - Dispense the treatment over the surface, applying enough to coat the entire surface. Allow excess material to drain.

 

 

Application Tips

  • In some cases, Kyzen cleaners like Ionox I3s416 or Cybersolv 141-R may be appropriate for removing surface contamination.
  • For dip applications, dip containers should be stainless steel, glass, or aluminum. Plastic containers are likely to contaminate the solution.
  • Use a microfiber cloth to wipe after cleaning.
  • Coat the substrate as soon as possible after cleaning to prevent recontamination.
  • Spray Equipment Suggestion
    • Spray & Dispense Valve - The PVA FCS300 Valve has been tested and confirmed compatible with all NanoProof products.
    • Manual Coating System - The PVA MCCS-SYS-1 Manual Conformal Coating System has been tested and confirmed compatible with all NanoProof products.
    • Automated & Selective Coating - The PVA Delta 8 Selective Coating / Dispensing System has been tested and confirmed compatible with all NanoProof Products.
  • Cure temperatures and conditions should be optimized based on substrate and durability requirements.

 

 

How to test for Hydrophobicity

To test for hydrophobicity, allow water droplets to fall onto the surface, which should bead up to a contact angle >90⁰. If the contact angle is <90⁰, then the surface is not
hydrophobic. The surface should be cleaned again and the treatment reapplied.
