For Contact Us page click here. 1) My customer has requested that we apply a Conformal Coating to their assemblies. We have never used a Conformal Coating before and were hoping you could provide us with some information about the different types of coatings. Answer: A good place to start would be HumiSeal's comprehensive Conformal Coatings Handbook, available on this web site. Additional information can be obtained via the IPC's CC-830 Conformal Coatings Handbook. This is available from the IPC at www.ipc.org . 2) We apply Conformal Coating to a small portion of our work and at this point do not want to perform the coating application in-house. Can HumiSeal provide information on contract coating services in my area? Answer: HumiSeal is aware of many quality contract firms who apply our coatings. To provide you with the latest information please contact us directly for information on contract coaters in your area 3) Our customer requires that we coat their boards with a Conformal Coating that is military qualified. Does HumiSeal have any coatings that meet the military specification? Answer: Yes, in fact HumiSeal has more products qualified to the Military's MIL-I-46058C specification than any other Conformal Coating Manufacturer. The product tables contained on this web site clearly state which of our products meet these rigid requirements. You may also view the Military's Qualified Products List (QPL) for this specification on their web site at; www.dscc.dla.mil/programs/qmlqpl/QPLdetail.asp?QPL=46058 . 4) We are required to use a Conformal Coating that is UL recognized. Does HumiSeal have any UL recognized Conformal Coatings? Answer: Yes a great many of HumiSeal's Coatings are recognized under the Component Program of Underwriters Laboratories, Inc., File Number E 105698. The product tables contained on this web site clearly state which of our products meet these requirements. You may also view a complete listing of HumiSeal's UL recognized Coatings on the UL web site at http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm . Once there simply insert HumiSeal's name into the company name space, hit search and our file will come up. 5) Conformal Coatings protect against moisture. If I use a Conformal Coating is my assembly waterproof. Answer: All Conformal Coatings can be described as semi permeable membranes. Although they protect the assembly from the negative effects of high humidity environments and water vapor, Conformal Coatings DO NOT render electronic or printed circuit assemblies waterproof against standing water. With a properly applied Conformal Coating an electronic assembly MAY be able to withstand full contact with water for a short time. However this is NOT RECOMMENDED. 6) There are so many different Conformal Coatings available, how do I know which one is right for my particular application? Answer: Selecting the best Coating for your application can be challenging. To assist you we have included a self-help "Decision Tree" accessible on this web site. We also suggest that your review HumiSeal's comprehensive Conformal Coatings Handbook available on this web site at Additional information can be obtained via the IPC's CC-830 Conformal Coatings Handbook, available from the IPC at www.ipc.org . 7) We are using a "No-Clean" assembly process. Do I still need to clean my boards prior to the application of a Conformal Coating? Answer: There are a wide variety of "No-Clean" products on the market and unfortunately not all are of equal quality. Therefore HumiSeal strongly recommends checking the compatibility of your "No-Clean" process with any Conformal Coating prior to starting production. Additional information about cleaning requirements and be obtained from the IPC at www.ipc.org,¬Ýby reviewing HumiSeal's Conformal Coating Handbook.and by checking for any technical papers on this web site that may pertain to cleaning. . However for maximum long term reliability, the best practice may be to follow the old adage "When in doubt - CLEAN" 8) Our company has been using HumiSeal coatings and applying them via manual methods. We are investigating automated application and need to know if HumiSeal's coatings are compatible with this type of equipment. If so, can HumiSeal make any recommendations regarding the equipment types? Answer: HumiSeal works very closely with all the major manufacturers of selective robotic application equipment. As a result all of HumiSeal's coatings are compatible with the majority of automated application systems on the market. For further information please contact HumiSeal directly at our Contact Us page. 9) Our design and prototyping work is done in one location but we have production facilities in several different countries. Is HumiSeal available globally? Answer: HumiSeal enjoys a presence on over thirty countries globally. Please check for the location nearest to your facilities at our Global HumiSeal page. 10) We are in the design phase of a new project and were wondering if you could provide us with the estimated cost of conformal coating a PCB assembly? Answer: The cost of actually applying the conformal coating to the assembly will vary greatly by application method and projected volumes. The material costs for the Conformal Coating itself are very low and will normally be less than $0.001 per square inch of board surface for a 1mil dry film thickness! This may vary slightly dependent upon the Conformal Coating ¬Ýused and can be further reduced dependent upon your purchasing volumes! Overall, the application of a quality Conformal Coating is the cheapest way to insure the long term reliability of your printed Circuit assemblies! Please contact HumiSeal directly for further assistance in determining your actual Conformal Coating costs at our Contact Us page. 11) We have been using HumiSeal Conformal Coatings for quite a while. Lately we are coming under more and more pressure by our local regulatory agencies to reduce the level of VOCs and HAPs we are emitting. Does HumiSeal offer any products that will enable us to meet these requirements? Answer: Yes! HumiSeal offers a full range of environmentally friendly Coatings. These Coatings have been specially formulated to retain their full reliability while addressing today's more stringent environmental regulations. HumiSeal offers Conformal Coatings and Thinners that are low in VOCs and HAPs, as well as a full compliment of VOC and HAPs free products. Please contact HumiSeal directly so that we may recommend the product which best fits your particular requirement 12) We are currently purchasing your Conformal Coatings in one gallon containers. Does HumiSeal offer other packing sizes and is so what are they? Answer: HumiSeal offers the majority of our Conformal Coatings, Thinners, Stripper and other products in a variety of package sizes. These package sizes include; US Quart, US Gallon, 5 US Gallon Pail and 55 US Gallon Drums. Dependent upon your global point of purchase, we also offer a full range of metric package sizes. Please contact HumiSeal directly so that we may assist you with the selection of the package size that best fits your needs¬Ý 13) Are samples of your products available and how do I obtain one? Answer: Yes! Samples of our products are readily available. Please contact HumiSeal directly so that we may recommend the product which best fits your particular requirement 14) We have reviewed your web site and can find no mention of a Parylene coating. What is it and do you provide it? Answer: Parylene, also know as Polyparaxylelene, is a very good Conformal Coating that applies by a vapor deposition process. However Parylene is also a very expensive coating. Not only is the material itself expensive, the equipment required to apply Parylene is also expensive. Parylene is vacuum deposited onto the assembly and one application cycle can require many hours to complete. Due to its cost and application issues, Parylene does not readily lend itself to large volume application and subsequently HumiSeal has chosen not to include it in our range of product offerings. If you have an application where you feel that Parylene may be required, there is a strong possibility that another Coating may suffice at far less expense. Please contact HumiSeal directly and allow us to assist you with a potential offset recommendation 15) How can I determine how much board coverage I can achieve using HumiSeal's coatings? Answer: To assist you with this answer we provide the following rough formula. This is a rough estimate and is based entirely upon a bare, unpopulated board and does not compensate for any transfer inefficiencies or waste.
