摘要： An element forming an electronic component has a first face and a second face facing each other, and a third face adjacent to each of the first face and the second face. A method of forming an external electrode of the electronic component involves a pre-formation step, first to third formation steps, and an electrode formation step. The pre-formation step is to apply a conductive paste onto the third face and to evaporate at least a part of a liquid contained in the applied conductive paste, to form a precoat portion expected to become a part of a third electrode portion. The first formation step is to apply the conductive paste from a direction opposite to the first face, onto the first face to form a first electrode portion. The second formation step is to apply the conductive paste from a direction opposite to the second face, onto the second face to form a second electrode portion. The third formation step is to apply the conductive paste onto the third face so as to cover the precoat portion, to form the third electrode portion. The electrode formation step is to dry the element to form the external electrode consisting of the first electrode portion, the second electrode portion, and the third electrode portion. The first electrode portion, the second electrode portion, and the third electrode portion are formed so as to connect with each other.

摘要： A method and device for forming external electrodes on opposing surfaces of an electronic chip. A plurality of chips are arrayed on a plate and held at a first end faces by a silicon rubber provided on the plate. The plate is brought close to a coating bed so that second end faces of the chips are immersed in an electrically conductive paste formed on the coating bed. The second end faces of the chips are coated with the conductive paste which forms first electrodes after drying step. Subsequently, the plate is inverted and brought toward a sheet with a foamable and releasable adhesive layer for allowing the chips to be pressed against the foamable and releasable adhesive and held thereby. The chips are transferred from the plate to the sheet. Next, second electrodes are formed on the first end faces. After the first and second end faces are formed with electrodes, the sheet is heated, causing the foamable and releasable adhesive in the sheet to foam and lose its adhesive strength to remove the components from the sheet by their own weight.

摘要： A method of forming an external electrode of an electronic component involves a paste preparation step, a removal step, an element preparation step, a contact step, and a formation step. The first step is to prepare a jig with a groove into which an element forming the electronic component can be inserted. The groove of the jig includes at least a first wall surface inclined outward in a direction from an interior toward an aperture. The paste preparation step is to fill a conductive paste in the groove. The removal step is to remove the filled conductive paste so as to leave the conductive paste along the first wall surface and remove the rest. The ealement preparation step is to locate the element immediately above the groove. The contact step is to insert the element into the groove and to move the element toward the first wall surface to bring a ridgeline of the element into contact with the first wall surface. The formation step is to move the element along the first wall surface and toward the aperture in a state in which the ridgeline of the element is kept in contact with the first wall surface, and to move the element away from the first wall surface so as to separate the ridgeline from the first wall surface.
