Abstract

Electronic coatings consist of a wide variety of materials that are used in the manufacture of electronic devices for military, industrial, and consumer usage. Coatings may be organic and inorganic compounds and polymers or metals. These coatings may be functional, providing electrical, magnetic, optic, mechanical, and/or thermal functions; they may be manufacturing aid coatings such as those used in the manufacture of circuit boards, or they may be protective or decorative coatings.

Polymeric materials are used to protect components from the environment and polymers having conductive metallic fillers are used to alleviate electromagnetic interference. Photoresists, inks or screenable resists, and solders all serve as coatings to produce microelectronic components such as printed circuit boards and integrated circuits.

Electronic coatings are applied in a wider range of coating widths and densities, under more stringent conditions, than conventional coatings. Both continuous and discrete coating methods employing a variety of solvents are used in designated clean rooms.
