Aculon's award-winning NanoProof® Series offer customers a range of PCB waterproofing solutions from protecting against accidental water damage (NanoProof 1.0) to IPX7, immersion in water at one meter depth for 30 minutes (NanoProof® 3.5, 4.0), to greater barrier properties that can withstand 100 hours immersion in sweat solutions and some of the most stringent test methods developed for non-hermetic components (NanoProof® 5.1).
Application of Aculon's Nanoproof 3.5
Parts Must be sufficiently clean prior to treatment for proper bonding and effective application.
Option – Spray (preferred method) Apply Aculon NanoProof® PCB Water Protection Treatment via spray gun. Aculon NanoProof® PCB Water Protection Treatment comes 1L Bottles for spray applications. Spray application typically results in treatment thickness of 50 nm - 20 µm depending on process parameters and chemistry selected. Recommended Equipment:
Option - Dip Fully immerse the part in the Aculon NanoProof® PCB Water Protection Treatment solution for 30 seconds. Withdraw the part at a steady rate to ensure even coverage. Allow to dry or cure depending on your substrate. Aculon NanoProof PCB Water Protection Treatments come in convenient 1L quantities for dipping applications. Option - Disperse Dispense product over the surface. Apply enough material to coat the surface. Utilization of multiple options Please note that many customers have found significant success utilizing two or more of the available NanoProof® technologies successfully. 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!
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 soldermasks and other substrate materials containing a UV tracer may make accurate detection of NanoProof difficult.
