Parylene Coating Alternative Technology

Parylene coatings have been used for some time to enhance the lifetime and reliability of electronics made to operate in harsh environments. Parylene coatings are expensive and difficult to apply. The high cost and difficulty required to apply parylene coatings are challenging for many markets. For many applications an alternative to the costly and time consuming parylene process is needed.

Parylene Coatings Vs Next Generation Protection

Application of parylene or CVD coatings has been used for some time to enhance the lifetime and reliability of electronics made to operate in harsh environments. Parylene coatings are typically used on PCBs to protect from moisture attack, chemicals, salt and other exposures. Parylene is expensive and difficult to apply, but has proven to be very reliable so is typically utilized in critical applications where 20+ years of performance are critical, such as aviation and military applications. The high cost and difficulty required to apply CVD are challenging for the consumer electronics market as product lifetimes of 1-3 years are typically all that is required.

Aculon NanoProof® line of coatings are cost effective solutions which exceed the performance of traditional parylene coatings while also addressing the negative issues associated with vacuum deposited Parylene.

Parylene Coating Challenges:

  • Extremely expensive capital equipment
  • Long batch times lead to low throughput and higher labor costs
  • Reworking is impossible or extremely difficult
  • Masking is complicated and time intensive
  • Difficult to do selective application

Challenges Addressed with NanoProof® Series:

  • Thin & uniform coatings. Good edge coverage.
  • Extremely quick dry times
  • Up to IPX7+ levels of protection
  • Easy to rework
  • No masking needed.
  • Flexible application methods
  • Thin coatings can be utilized in nearly any packaging configuration

NanoProof® Customized Solution

For parts that are complicated, require formulary work, or selective/complex treatment, Aculon® can work directly with you on your application. We will customize a solution to fit your specific needs. Once a solution has been determined, Aculon® will assist with implementation in your facility and bulk chemistry and cleaning solutions can be delivered on a monthly/weekly basis to meet your production needs.

Key questions to consider for waterproofing your boards:

  • Is full immersion or incidental moisture protection required?
  • Do you have a specific thickness requirement or need for a flexible treatment?
  • What are the exposure conditions the selected treatment (and treated product) must survive?
  • Is there a desired application method? (Spray, Dispense, etc)
  • Does the part require selective application to only certain areas?
  • Are there low/no VOC requirements in your production facility?
