Abstract

The invention discloses plasma vacuum coating equipment with the function of electrode and workpiece movement and a using method. The equipment comprises moving electrodes, a vacuum air exhausting device, a plasma vacuum cavity, a workpiece driving moving device, a plasma discharge source and an air inlet channel; the plasma discharge source and the vacuum air exhausting device are arranged on theexterior of the plasma vacuum cavity; and the moving electrodes and the workpiece driving moving device are arranged in the plasma vacuum cavity. The using method of the equipment comprises the following steps that the plasma vacuum cavity is vacuumized, and coating is conducted on a to-be-coated workpiece. According to the plasma vacuum coating equipment with the function of electrode and workpiece movement and the using method, the coating sedimentation rate and the coating production efficiency are improved by adopting a plasma-enhanced chemical vapor deposition method, the coating uniformity and consistency are improved, the protection effects such as water prevention, sweat prevention, moisture prevention, corrosion resistance and solvent resistance of a coating are improved, and theplasma vacuum coating equipment can be applied to various coating occasions such as PCBs, PCBAs, electronic products, electric appliance parts, electronic semi-products, metals, electronic components, semiconductors, integrated circuit boards and plastic products.

Description

technical field [0001] The invention relates to the technical field of plasma chemical vapor deposition, in particular to a plasma vacuum coating device and a use method for electrode and workpiece movement. 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] Th...
