Introduction
== Introduction ==
A According to [https://en.wikipedia.org/wiki/Conformal_coating Wikipedia], a conformal coating is "a thin electrically non-conductive protective coating that conforms polymeric film which ‘conforms’ to the contours of a printed circuit board to protect the PCBs or electronic assembliesboard's components". The primary main purpose for conformal coating of PCBs in satellites or other space applications is the protection of electronic assemblies and components from environmental contaminants including which include particles, dust, dirt, moisture, corrosive vapors, and fungus.<ref name = "ref1">http://prod.sandia.gov/techlib/access-control.cgi/2008/081125.pdf</ref>
=== Why use Conformal Coating? ===
Many Because there are mass and volume constraints in space, the packing of components is very tight in many electronic assemblies are tightly packed with components, thus having which results in very small spaces space between conductors (e.g., like solder pads and , or leads).If a particle settles in this small space, it may lead to a short circuit. Particles, that can settle onto on electronic modules during productionmanufacture, soldering, ground testing, and launch or buoyant particles in the zero-gravity space environment on in orbit that contact and span two or more closely spaced conductors may result in a . The short circuit, leading can lead to potentially serious catastrophic electrical failures in the a satellite system. Despite Inspite of all efforts to keep satellite assemblies clean and free from contaminants, the possibility that of stray particles, metal shavings, dust, and dirt will be being present always exists. <ref name = "ref1" />
