I am asked quite often about conformal coating classification. The reality is conformal coatings can be classified in many ways.
However, the IPC do a great job of splitting out the various subdivisions.
They include:
- Liquid or vapour deposition materials
- Organic or inorganic coatings
- The resin types (AR, UR, SR, XY, FC)
- Drying and curing mechanisms
- One or two part materials
- Solvent or non-solvent based
A typical family tree for conformal coatings is shown below:
