Conformal coatings are designed to protect printed circuit boards (PCBs), assuring they work under all operational circumstances. However, cases emerge where boards fail to function despite conformal coating protection. Such non-performance can be a consequence of:Read More

NASA certification is essential to aerospace conformal coating applications, and thus is sought after by many firms in the industry. In addition to 8739.1, other NASA standards, such as ASTM E595 – a test developed by NASA to determine levels of coatings’ volatile content, appropriately screening low outgassing materials for use in space – are inspection and performance parameters applicable to aerospace uses.
The AS9100/9120 and ISO9001 qualification are international aerospace standards for quality assurance, development, production, installation, and servicing also relevant to quality workmanship for aerospace products and the firms that manufacture them; equally relevant are IPC-CC-830 and IPC--A-610 classifications, from the Association Connecting Electronics Industries, often considered equivalent to NASA 8739.1 for aerospace conformal coatings. Nadcap’s AC7120 Rev A - Nadcap Audit Criteria for Circuit Card Assemblies is also applicable.Read More
