<p>PURPOSE: To enhance part holding force and to ensure prescribed holding force in necessary min self-adhesive tape width by heating the lead wires of radial lead electronic parts to mount them on pasteboard by a self-adhesive tape. CONSTITUTION: After a silver electrode is formed on a varistor element based on zinc oxide, two lead wires are soldered to the varistor element and radial lead electronic parts 1 provided with exterior elements by an epoxy resin are mounted on pasteboard 4, for example, by a self-adhesive tape 3 with a width of 13mm to be heated by the hot air of about 180 deg.C from a hot jet using a nickrome heater. At the same time, the lead electronic parts 1 are heated, for example, by using an induction heater with frequency of 400kHz and output of 2kW and pressed through the self-adhesive tape 3 to be bonded to the pasteboard 4. By this constitution, prescribed part holding force can be ensured in necessary min. self-adhesive tape width and a taping product of electronic parts can be obtained in low cost.</p> |
