Abstract

The invention discloses a microwave plasma vacuum film coating device and a using method. The device comprises a plasma generating system, a vacuum exhausting device, a plasma vacuum cavity and a movement device; the plasma generating system and the vacuum exhausting device are arranged outside the plasma vacuum cavity; and the movement device is arranged in the plasma vacuum cavity. The using method of the device comprises the following steps that the plasma vacuum cavity performs vacuumizing to perform pretreatment, film coating and the like on products to be subjected to film coating. According to the microwave plasma vacuum film coating device and the using method, a plasma chemical vapor deposition method is adopted for increasing the sedimentation rate of film coating substances andthe film coating production efficiency, and the film coating uniformity and consistency are improved; and meanwhile, the protective effects of waterproofness, sweat preventing, moisture preventing, corrosion resisting, solvent resisting and the like of a coating are improved at the same time, and application in occasions of various PCB, PCBA, electronic products, electric appliance parts, electronic half-finished products, metal, electronic parts and components, semiconductors, integrated circuit boards, plastic products and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of plasma chemical vapor deposition, in particular to a microwave plasma vacuum coating device and a use method. Background technique [0002] Plasma Enhanced Chemical Vapor Deposition PECVD: It uses microwave or radio frequency to ionize the gas containing the constituent atoms of the film to form plasma locally, and the plasma is very chemically active and easy to react, depositing the desired film on the substrate . In order to enable the chemical reaction to proceed at a lower temperature, the activity of the plasma is used to promote the reaction, so this CVD is called plasma-enhanced chemical vapor deposition (PECVD). Experimental mechanism: The gas containing the constituent atoms of the film is locally formed into plasma by means of microwave or radio frequency, and the plasma is chemically active and easily reacts to deposit the desired film on the substrate. [0003] The existing coating equipmen...
