Abstract
The invention relates to a small patch fuse and a manufacturing method, in particular to a small patch fuse which can improve the electrical properties, and a manufacturing method thereof. The small patch fuse takes a glass-ceramic layer as the substrate and takes the fuse metal or alloy as the internal electrodes to form a monolithic structure; both end parts of the monolithic structure are provided with end electrodes, wherein, one or more layers of internal electrodes are arranged between two glass-ceramic layers; both ends of each internal electrode are contacted with each end electrode; the middle part of the internal electrode is a fuse part; the upper and lower surfaces of the internal electrode are respectively provided with attached glaze layers; the attached glaze layers cover the entire fuse part of the internal electrode; besides, the length and width of the attached glaze layers are less than the length and width of the monolithic structure. The attached glaze layers can prevent the internal electrodes and the ceramic body penetrating each other in the co-firing process and improve the consistency of product resistance and electrical properties, and also achieve the effect of thermal insulation, so that the fuse part can quickly and effectively act.
Description
technical field [0001] The invention relates to a small chip fuse and a manufacturing method thereof, in particular to a small chip fuse with improved electrical performance and a manufacturing method thereof. Background technique [0002] Due to the requirements of production accuracy, the small chip fuse with a monolithic structure usually only prints one or more layers of internal electrodes, and then separates them with a glass-ceramic body. The applicant of the present invention discloses a chip type fuse in its Chinese Patent Publication No. CN101202186, which cuts a slit in the width direction of the glass ceramic substrate, so that the metal thin film material used as the internal electrode extends from between the substrates to the end surface of the substrate, and then The terminal electrode is changed to change the line-surface contact between the internal electrode and the terminal electrode into surface-surface contact, thereby improving the contact strength. ...
