Businesses must weigh all these factors when determining whether a worker is an employee or independent contractor. Some factors may indicate that the worker is an employee, while other factors indicate that the worker is an independent contractor.
Conformal coating material is a thin polymeric film which âconformsâ to the contours of a printed circuit board to protect the board's components.he selection of conformal coating material is a crucial factor that needs to be considered carefully and in relation to the application method. The wrong selection can not only affect the long term reliability of the circuit board but can cause massive difficulties with both processing and costs.
Hydrophobic coatings protect various materials (metal, wood, plastics, leather, and fabric and nonfabric fibrous ma-terials) from the destructive action of water or wetting. They are used particularly extensively in machine building,construction, and textile production.1  Facebook.ubstances used as hydrophobic agents include salts of fatty acids and such metals as copper, aluminum, and zirconium; cation-active surface-active agents; and low-and high-molecular-weight organosilicon and organic fluorine compounds.
