Abstract

The invention provides a manufacturing method of a component electrode. The manufacturing method comprises the following steps: (1) casting a ferrite base material: coating and casting ferrite slurry, and drying to form the ferrite base material; (2) printing a conductive adhesive on a release film: printing a photosensitive conductive adhesive layer on the PET release film, and heating and drying; (3) mask exposure: an electrode pattern mask is placed above the dried photosensitive conductive adhesive, and the photosensitive conductive adhesive is exposed, cured and denatured through ultraviolet irradiation; (4) showering and developing: showering and developing by using a developing solution, and forming an electrode pattern on the PET release film; and (5) temperature and pressure transfer: transferring the electrode pattern formed on the PET release film to the ferrite base material under the action of certain temperature and pressure. According to the method, the problems of ghost shadow, defect and the like when the ferrite base material is exposed and developed to manufacture the electrode are solved through the self-made ferrite slurry, the photosensitive conductive adhesive and the temperature-pressure transfer process.
