Other teams have resorted to just applying a silicon coating after all the debugging is done or using a full 3d printed enclosure. I would hesitate to take these routes because of my understanding of our project constraints. We are heavily dependant on passive air cooling so fully enclosing the board may not be feasible. Also, from what I understand we had the dust issues before the competition and need a solution during the testing phases too.
IPC Standards
IPC-CC-830C: This is the main standard for conformal coating. It is used to qualify different conformal coating products, and contains sections on materials, shelf life, curing, chemical, viscosity, and appearance requirements. It also contains standards on fungus, moisture, and flammability resistance as well as dielectric withstanding voltage and other electrical specifications.
IPC-A-610G: This standard covers the acceptability of electronics assemblies, and as such has a section on the requirements for conformal coating coverage and thickness.
IPC J-STD-001F: This standard covers the requirements for soldered electrical and electronic assemblies, and has a section dealing with materials and application of conformal coatings
