Some of these include:<\/p>\n<div align=\"justify\">\n<ul>\n<li>Apply thermal compounds wherever necessary to dissipate heat.<\/li>\n<li>Apply additional shielding and grounding on critical traces.<\/li>\n<li>Apply high quality acrylic-based sprays to coat the PCBs protecting them from the aggressive environment of the applications.<\/li>\n<li>Use mil-spec components than using commercial grades.<\/li>\n<li>Use proper termination techniques.<\/li>\n<li>Select materials and components carefully to withstand extreme heat. These include Pyralux AP, epoxy laminates like FR408, and various metal core materials.<\/li>\n<li>Use extremely reliable finishing materials for enhanced protection in harsh conditions. Some of the most commonly used finishing materials in the assembly of military and aerospace PCBs include:\n<ul>\n<li>ENIG<\/li>\n<li>Electrolytic nickel and gold<\/li>\n<li>ENEPIG<\/li>\n<li>Lead Free HASL<\/li>\n<li>Immersion silver<\/li>\n<li>Electrolytic wire bondable gold<\/li>\n<li>SMOBC<\/li>\n<li>Immersion gold<\/li>\n<li>HASL<\/li>\n<\/ul>\n<\/li>\n<li>Manufacture <a href=\"http:\/\/www.rigiflex.com\/industry-served\">military and aerospace grade PCBs<\/a> in conformance with MIL-PRF-31032, MIL-PRF-50884, and MIL-PRF-55110 standards.<\/li>\n<li>Verify the flexural strength, bond strength, trace width, thickness, resolution, protective coatings, and dielectric thickness etc. thoroughly before dispatching. \u00a0Make sure that they are ready for use in hostile industrial environments.<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\">Design military and aerospace grade PCBs keeping quality and durability as paramount importance.
