Features & Benefits

IDC estimates 900,000 smartphones are damaged by liquid every day. Until now, this was a problem without a great solution. Previously, water-resistance product offerings generally fell into two categories: solution-based conformal coatings that repel fluids but require some level of masking or “keep-out” areas, and vacuum-deposited coatings (which also require masking) such as parylene-based treatments. Aculon® NanoProof® surface treatments create a third category – no mask solution based hydro/oleophobic encapsulants that are done on an inline basis and deliver the benefits of a conformal coating yet eliminate the need for costly capital investment and avoiding the bottlenecking batch process of vacuum based manufacturing or masking operations.

Aculon® 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® 2.1, 7.0, 8.4), 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® 2.1, 7.0 & 8.4).

Aculon NanoProof® Series uses a mix of Aculon® Proprietary Transition Metal Complexate technology (TMC) and fluorinated acrylic polymers to achieve a series of products that are compatible with all of the common material types used in SMT parts. Aculon® NanoProof® series are sprayable or dip based treatments that do not require a cure and have no impact on conductivity testing. While some of the NanoProof® series are so thin that they are invisible to naked eye, all of the Nanoproof® series contain a UV tracer to ensure detection at customer sites.

Benefits of the NanoProof® Series includes:

  • Improved device reliability due to protection of PCBs from water damage
  • From accidental submersion (IPX 4), water immersion for 30 minutes (IPX7) to prolonged immersion (IPX 8)*
  • Reduced product returns due to device failures
  • Reduces cost as no masking required
  • Improves yields as enables rework after coating
  • Can be applied via spray, dispense, jet, film, or dip, thereby eliminating need for costly vacuum deposition equipment
  • Save energy compared to vacuum deposition process
  • Improve throughput as does not require batch production
  • Safe for use in factory environment – non toxic
  • Electrical connections unimpacted – No impact on signal strength, antenna or acoustic performance (NanoProof® 1.0, 4.0, & 5.1 only)
  • Flexible encapsulants resist cracking/flaking

Features of the NanoProof® Series includes:

  • Liquid at room temperature
  • Ability to protect many substrates on a PCB
  • Post treatment water contact angle from 100 to 120 degrees*
  • Post treatment oil resistant – contact angle up to 76 degrees*

Application of conformal coatings has been used for some time to enhance the lifetime and reliability of electronics made to operate in harsh environments. Conformal coatings are typically used on PCBs to protect from moisture attack, chemicals, salt and other exposures. There are several key challenges utilizing traditional conformal coatings in consumer electronics with very strict tolerances, performance requirement, and high volume UPH required. Challenges with traditional conformal coatings include:

  • Difficulty maintaining uniform thickness. Poor edge coverage leads to failure
  • Long cure times lead to poor throughput
  • Reworking is impossible or extremely difficult
  • Masking is complicated and time intensive
  • Coatings are thick making it difficult to incorporate into tight tolerance configurations
  • High viscosity formulations lead to limited application methods

 

Aculon® NanoProof® line of coatings are cost effective solutions which exceed the performance of traditional conformal coatings while also solving the above issues:

  • Thin and 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

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. Other challenges with parylene and CVD coatings include:

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

 

Aculon® NanoProof® line of coatings are cost effective solutions which exceed the performance of traditional conformal coatings while also solving the above issues:

  • Thin and 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

Enabling IPX Level 7/8
PCB Waterproof Protection

Examining NanoProof® qualifications for IPX7 and IPX8 level protection for electronic devices.

Every PCB has an Achilles heel: water. Is there a solution beyond conformal coatings?

Aculon makes the front page with whitepaper featured in Circuits Assembly September 2018 edition.

FAQs

1) How durable is NanoProof® ?
ANSWER: NanoProof® is designed to provide protection against water and moisture damage. It is designed to have lasting exposure to oxygen/light with great durability. It is not however designed to provide abrasion durability as the substrates it coats are typically contained within an out case and not exposed to abrasive action.

2) Can these treatments be applied over a no-clean Flux?
ANSWER: Yes, our chemistry can be applied to boards where no clean flux has been used. Fatty acids compounds are often used and traces are left behind. These traces are not water soluble but solvent soluble. For any traces left behind it would be best to clean with a solvent first. Our treatment is not water soluble, but is solvent soluble. If you have an open flux, you may need to clean material. Leaves a partially conductive residue.

3) Do any options require special spray equipment? Can we use our existing spray systems/equipment?
ANSWER: Yes, the product is designed to be used with standard spray equipment. Acrylic conformal spray equipment is optimal. Automated and selective spray equipment can be sourced via PVA at pva.net.

4) What is a typical oil contact angle for NanoProof® 5.1?
ANSWER: About 78° – typically in the high 70°’s. As a point of reference: An untreated product, depending on the substrate, would fall somewhere in the 10°-20° degree range.

5) How it is the product cured when applied? Is it a UV or heat cure or is it a room temperature dry?
ANSWER: Room Temperature drying is all that is typically needed. A quick cure is possible – which does not damage the coating. Longest air dry time is typically no longer than 30 minutes. Can reduce drying rates by adding heat. A heated cure typically does not add performance benefits.

6) Which application process is better? Dispensing, manual spray, or dipping?
ANSWER: Depends on the process you use and your part to be coated. No easy answer. Comes down to testing and what you need in the areas that are going to cause the most problems on your specific part. However in general spray is often preferred for application of 1.0, 3.5, 4.0, 5.0, & 5.1. Also keep in mind, 7.0 & 8.4 can not be applied via spray due to their thick nature and must be applied via dip or film coat.

8) We use a specialty coating robotic that needs to be cleaned once done. Are the Nanoproof® treatments easy to clean once the job is done?
ANSWER: Yes, we can provide the appropriate solvent for cleaning after use. It is not difficult when utilizing the proper solvent, just like cleaning a paint brush with paint thinner.

9) Is there a high-temperature curing step?
ANSWER: No, none required. These treatments can handle some level of high temperature after being applied, however it is recommended to not go over 200°C for any of the NanoProof® encapsulants. If you wish to increase the speed of the line, the option to use high temperature to cure is available.

10) Can it be applied over a traditional conformal coating such as parylene in order to obtain additional performance and protection?
ANSWER: Yes, it can be applied over conformal coatings. However, this is not something we have tested to evaluate the performance and protection change. Typically the value proposition with use of NanoProof® is replacing a parylene coating with our more cost effective, scaleable, and easy to apply NanoProof® encapsulant options rather than doubling down.

11) Are these materials currently being used in any OEMs or CEMs that we can reference?
ANSWER: Yes, they are being used; however, due to confidentiality, we cannot reference customer names. We have worked with several customers over a time period to ensure that the products work as intended. These products are commercially available and commercially used.

12) How do you test or check if the coating is on the surface?
ANSWER: A UV Tracer is added into every version of NanoProof. The UV Tracer utilized is visible under a 365 nanometer light. For QC purposes, the treatment illuminates blue under the UV lamp which gives an indication of how well you have treated your parts.

13) Do connections or solderable surfaces need to be masked?
ANSWER: This is dependent on the application and which NanoProof® is selected. No masking is typically required for application of NanoProof® 1.0, 3.5, 4.0, & 8.4. These materials are designed around having a push thru connectivity at all the times. Even days or weeks later – you can still push through. NanoProof® 5.0, 5.1, & 7.0 have a limited window for making electrical connections, generally around an hour or so after application. Once NanoProof® 5.0, 5.1, & 7.0 have set, it is possible to use a bit of fluorosolvent (available through Aculon® , please call 858-350-9474) around the specific area to allow for push through connectivity.

14) Can you dip coat unsealed switches?
ANSWER: Yes, with NanoProof® 1, 3.5, 4.0, there is no problem with this. With NanoProof® 5.0, 5.1, 7.0, & 8.4 – though it has not been tested, it most likely would not work due to its more rigid structure once it has set.

15) Has any testing been done for protection against steam, such as use in an Autoclave?
ANSWER: This is not a problem so long as you do not go above the recommended max temp of 200° degree C. Autoclaves do not typically get that hot.

17) What are the Carrier Solvents?
ANSWER: For NanoProof® 1.0, 3.5 & 4.0, the carrier is a Hydrocarbon Solvent. For NanoProof® 5.0, 5.1, & 7.0 the carrier is a fluorosolvent blend.

18) Do we have measured viscosities of the various treatments?
ANSWER: For NanoProof® 1.0, 2.0, 3.5, & 4.0 it is very low, less than a centipoise. For NanoProof® 5.1 – it depends on the application formulation selected. It is fairly light in viscocity in the 1-10 centipoise range. 7.0 & 8.4 have viscosities higher than 20 centipoise.

19) Are there disadvantages for a surface that has been over-applied or applied to be too thick?
ANSWER: No, only thing to be impacted would be the push-thru connectivity with a treatment that is too thick. For NanoProof® 5.1, two treatment layers may impede push-thru if you spray it, let it dry and spray again. This may prevent you from being able to do a push-pin connection.

20) Does the applied thickness impact conductivity?
ANSWER: Our NanoProof® films themselves are not conductive. NanoProof® 1.0, 2.0, 3.5, 4 .0 & 8.4 will be able to push through (allowing electrical connections to be made) with no impact to conductivity. NanoProof® 5.0, 5.1, & 7.0 is a firmer barrier – you will need to peel off or use a fluorosolvent to re-wet the area if you want to go through it.

21) If we wish to test the material, how do we obtain it? Direct or through distribution?
ANSWER: Depends somewhat on the region where you are located. In the United States, we distribute directly from our warehouse in Southern California. In Asia, we will have local distributors which we can re- direct you to. Because we have a mixed model, it is best to contact us if you have any questions. We will connect you with the best source based on location.

22) What are some common treatment cosmetic defects which are seen, such as fish eyes or de-wetting.
ANSWER: You might see some haziness in the treatment if put on a clear substrate. You would not see fish-eye, but quite possibly orange peel style defects where one area is slightly higher than another. This usually happens when the solvent is really rapidly dried by heating the substrate or when the product is used outside of the specification.

23) Is NanoProof alcohol and chlorine proof?
ANSWER: Performance testing has been done in saltwater (sodium chloride) and NanoProof® performs well. Alcohol will not dissolve the treatment. In short, it shouldn’t have an impact – but along with other liquids that are not specifically mentioned in our tests, we recommend testing if there is concern.

24) Because Parylene is vapor applied and the NanoProof® materials are liquid applied, my assumption is that the edge thickness does not compare to parylene. Do you have any information on this?
ANSWER: This is not something we’ve measured and will likely not compare to the uniformity of parylene. However the performance testing is positive and ultimately is typically what is most important. If edge thickness is critical to you we do find that you can do multiple applications in a far shorter cycle time.

25) What is the application rate?
ANSWER: Typical application time is 30 seconds for dipping. However, every part is unique – so your part may need some process optimization. The withdrawal speed will also impact the thickness. Spraying can be done in seconds.

26) Do the treated surfaces remain solderable or can you solder through a treated PCBA.
ANSWER: For NanoProof® 1.0, 3.5 & 4.0, yes it is possible to solder through a treated PCBA. With NanoProof® 5.0, 5.1, & 8.4 during the first hour window of dry time you can solder before the material has set. Once the film has set, take a clean room swab, dip in fluorosolvent, and rub over the area you want to solder.

27) Do these products have low boiling points?
ANSWER: Boiling points for NanoProof® 1.0, 3.5 & 4.0 are in the 90 – 100°C range. For NanoProof® 5.1, it would depend on which application you choose, dip, spray or dispense. The solvent range boiling point is 85 – 140°C.

28) Do these encapsulants comply with ROHS and REACH regulations?
ANSWER: Yes, no heavy metals, no VOAs, no v-techs.

29) When you make a push through connector does it remain sealed?
ANSWER: Assuming that the treatment covers the bare metal lead – Yes.

30) Where does the product ship from?
ANSWER: The products are manufactured at our facility in California. Orders from the United States market will ship from California. We do have some distributors in Asia who will carry and ship for orders in that area.

31) Can a regular test tape be used to test for adhesion?
ANSWER: An adhesion tape test is not really relevant for NanoProof® 1.0, 3.5, & 4.0 – these are actually still semi-liquid once they are down. NanoProof® 5.0, 5.1, 7.0, & 8.4, on the other hand, does cure into a hard treatment. So yes, once cured, a tape test can be utilized to test for adhesion.

32) Have you done any accelerated life testing such as what is used in automotive or medical?
ANSWER: No, we have not, as this is typically unique per the specific application and performed by the customer utilizing the application specific part. Feedback from customers is that there is not a concern surrounding any testing performed that shows degradation in the life of the board. We have just tested performance in water and salt water and found no impact.

33) How much NanoProof® is needed for a certain size?
ANSWER: For all products: In general, approximately 1ml per square foot of surface area for dipping. For example a 3″x5″ board would use less than a ml. Spray utilizes approximately 1-3 ml per square foot of surface area. Spray can be more efficient if not all surfaces need treatment.

34) When breaking through encapsulant with mounting screws, will water migrate under the coating?
ANSWER: No, not in our experience.

35) You mention that NanoProof® allows for electrical connections. Is the treatment itself conductive?
ANSWER: The treatments are all non-conductive by nature. They do allow for connections to be made through them by pushing out of the way or due to their ultra thin nature. They will not impact the conductivity of a treated trace. By design our products are meant to keep conductivity from bridging.

36) How well does it perform under extreme conditions. – 40°C to 80°C?
ANSWER: Based on chemistry, it will survive both very well. All NanoProof® materials are stable at this temperature range.

37) Would our products pass Mil 4658C or IPCCC830? For Biocompatible, ISO10993?
ANSWER: This testing has not been done at this stage. It is likely they would pass. If a customer with a significant enough project requiring this was interested, we are glad to look into the possibility.

38) Are you planning to test repellency or have you tested for other fluids in the auto industry, i.e. brake fluid and gasoline?
ANSWER: Due to the shear # of liquids which can potentially be tested, we have not tested every possible scenario. However NanoProof® is both hydrophobic & oleophobic – you would expect to see the high contact angles for most oil and water based liquids.

39) If you want to have a thinner thickness for each type of treatment for application what is your recommendation?
ANSWER: If thinner coverage is required, we can potentially lower the actives %. We do not encourage you to dilute the concentration, as it goes on very thin as is, and therefore provides a cost-effective treatment. We can work to customize the concentration once you have tested samples and can confirm your needs.

40) How do you suggest I test if a water proof encapsulant is needed for my part? Also, How do I determine which NanoProof® meets my performance needs?
ANSWER: From working with our customers, we see that there is a huge variety of testing: we have manufacturers of medical devices that are worried about splashing of liquid on their device, other who need IPX7 qualification or others who require even longer periods of submersion in a variety of solutions.

Determine the level of exposure and performance you want the part to pass– connect the device (board), turn the power on the unit and test against those conditions.

If you want something very simple for humidity – go with something straightforward like NanoProof® 1.0. If you want full submersion of a running device over a long period of time NanoProof 7.0 OR 8.4 is likely most appropriate. NanoProof® 3.5, 4.0, 5.0, & 5.1 fit somewhere in the middle performance wise and are usually robust enough to meet most performance specs.

41) How does the UV tracer impact the capabilities of the waterproof treatment?
ANSWER: We have not found any negative impact. If a treatment with no UV tracer is desired, this can be arranged. Please inquire for information.

43) What intensity of UV light is advised for UV Tracer?
ANSWER: Aculon® uses a 4 watt UV lamp at 365 nanometers in the lab. A stronger or weaker lamp will likely work, just be sure that it is a 365 nm UV lamp.

44) What type of PCB handling is recommended or allowed after treating with 3.5 or 4.0?
ANSWER: Keep in mind both 3.5 and 4.0 are never actually cured and are gel like in nature (allows for push through connectivity!) and should be handled carefully. Once inside of the units enclosure, this is not a concern. Hold in an area you are not trying to protect. Usually there are plenty of parts on the board or the edge of the board where you can handle and get it on to the next step of manufacturing without actually disturbing the leads on the ic or where the power slides come in. Basically, don’t handle in the areas that you are trying to protect as the treatment is still deformable.

Push-Through Connectivity®

One of NanoProof® most significant advantages over conformal coatings is the fact that electrical connections can be made through the NanoProof® treatment in many cases. NanoProof® 1.0, 4.0, 7.0, and 8.4 have full push-through connectivity capability, while 2.0 and 5.1 allow for push-through connectivity within 20 minutes of treating the board.
