Book excerpt: This final report covers the research and development work done on conformal coatins and is divided into five phases: Phase A - Evaluation of commercially available conformal coatings such as: epoxies, polyurethanes, silicons, acrylics and polystyrene materials, and their ability to meet the requirements specified in PR+C 61-SIMSA482 in order to obtain data for the preparation of a three services coordinated military specification. In this phase is also discussed the effect of coating thickness on insulation resistance and Q factor at 1, 50 and 100 mc under prolonged high humidity conditions. Phase B Investigation of methods for removing the conformal coating to permit replacement of parts when necessary without impairing the functional operations of the unit. Phase C - Evaluation, for upgrading purposes, of the allowable minimum spacing between conductors on uncoated and coated boards. Phase D - Study the effect of conformal coating on copper, gold and solderplated conductors with respect to their effect on Q factor and capacity at 1, 50 and 100 mc. (Author).

Book excerpt: Conformal coatings are used in space applications on printed circuit board (PCB) assemblies primarily as a protective barrier against environmental contaminants. Such coatings have been used at Sandia for decades in satellite applications including the GPS satellite program. Recently, the value of conformal coating has been questioned because it is time consuming (requiring a 5-6 week schedule allowance) and delays due to difficulty of repairs and rework performed afterward are troublesome. In an effort to find opportunities where assembly time can be reduced, a review of the literature as well as discussions with satellite engineers both within and external to Sandia regarding the value of conformal coating was performed. Several sources on the value of conformal coating, the functions it performs, and on whether coatings are necessary and should be used at all were found, though nearly all were based on anecdotal information. The first section of this report, titled 'Conformal Coating for Space Applications', summarizes the results of an initial risk-value assessment of the conformal coating process for Sandia satellite programs based on information gathered. In the process of collecting information to perform the assessment, it was necessary to obtain a comprehensive understanding of the entire satellite box assembly process. A production time-line was constructed and is presented in the second section of this report, titled 'Satellite Box Assembly', specifically to identify potential sources of time delays, manufacturing issues, and component failures related to the conformal coating process in relation to the box assembly. The time-line also allows for identification of production issues that were anecdotally attributed to the conformal coating but actually were associated with other production steps in the box assembly process. It was constructed largely in consultation with GPS program engineers with empirical knowledge of times required to complete the production steps, and who are familiar with associated risks from activities such as handling, assembly, transportation, testing, and integration into a space vehicle (SV) system. Finally, section three titled, 'Summary and Recommendations for Future Work', briefly summarizes what we have learned and describes proposed future work.

Book Synopsis Coating Materials for Electronic Applications by : James J. Licari
Download or read book Coating Materials for Electronic Applications written by James J. Licari and published by William Andrew. This book was released on 2003-06-11 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first book in the Materials and Processes for Electronics Applications series answers questions vital to the successful design and manufacturing of electronic components, modules, and systems such as: - How can one protect electronic assemblies from prolonged high humidity, high temperatures, salt spray or other terrestrial and space environments? - What coating types can be used to protect microelectronics in military, space, automotive, or medical environments? - How can the chemistry of polymers be correlated to desirable physical and electrical properties? - How can a design engineer avoid subsequent potential failures due to corrosion, metal migration, electrical degradation, outgassing? - What are the best processes that manufacturing can use to mask, clean, prepare the surface, dispense the coating, and cure the coating? - What quality assurance and in-process tests can be used to assure reliability? - What government or industry specifications are available? - How can organic coatings be selected to meet OSHA, EPA, and other regulations? Besides a discussion of the traditional roles of coatings for moisture and environmental protection of printed circuit assemblies, this book covers dielectric coatings that provide electrical functions such as the low-dielectric-constant dielectrics used to fabricate multilayer interconnect substrates and high-frequency, high-speed circuits. Materials engineers and chemists will benefit greatly from a chapter on the chemistry and properties of the main types of polymer coatings including: Epoxies, Polyimides, Silicones, Polyurethanes, Parylene, Benzocyclobenzene and many others. For manufacturing personnel, there is an entire chapter of over a dozen processes for masking, cleaning, and surface preparation and a comprehensive review of over 20 processes for the application and curing of coatings including recent extrusion, meniscus, and curtain coating methods used in processing large panels. The pros and cons of each method are given to aid the engineer in selecting the optimum method for his/her application. As a bonus, from his own experience, the author discusses some caveats that will help reduce costs and avoid failures. Finally, the author discusses regulations of OSHA, EPA, and other government agencies which have resulted in formulation changes to meet VOC and toxicity requirements. Tables of numerous military, commercial, industry, and NASA specifications are given to help the engineer select the proper callout.
