Process for a surface treatment of a glass fabric |
摘要 |
A surface treatment of a glass fabric used for a fiber reinforced composite such as multilayer circuit boards comprises the steps of exposing the glass fabric to an atmospheric pressure plasma of a mixture gas to obtain a plasma-treated surface of the glass fabric, and coating an organosilane compound on the plasma-treated surface. The mixture gas contains as a reaction gas at least one of an oxidative gas and a fluorine-containing gas, and a rare gas as a carrier of the reaction gas. The mixture gas is pre-heated prior to the plasma excitation thereof. When the glass fabric includes an organic compound as a sizing agent, the organic compound can be efficiently removed from the glass fabric by the exposing step. For example, the organosilane compound can be coated on the plasma-treated surface by exposing the plasma-treated surface to a second atmospheric pressure plasma of a second mixture gas containing an organosilane monomer. The surface treatment of the present invention is useful to efficiently produce a multilayer circuit board having excellent adhesion between the glass fabric and a resin, and resistance to CAF (Conductive Anodic Filaments).
