METHOD FOR WINDING LEAD WIRE ON MULTILAYER COIL ELECTRONIC COMPONENTS

摘要

Provided is a method for winding lead wire on multilayer coil electronic components that prevents lead wire coil sagging or breaking and terminal disconnection failures. The lead wire (9) is wound on a core (7) only a prescribed number of turns, forming a first layer (17) and a second layer (18). The lead wire (9) is folded back in the direction of an electrode (4b), is pulled in the direction of the electrode (4b) on the coil ending side to cross over the second layer (18), and is wound around an exposed portion of the core (7) between the coil ending portion of the first layer (17) and a flange (8b). The lead wire (9) is additionally hooked on the base (20) of the flange (8b), and a final terminal part (10b) is formed. The final terminal part (10b) of the lead wire (9) is then thermocompression bonded to the electrode (4b).
