Production manner null of the electronic parts which possess the lead/read

摘要

PURPOSE: To suppress generation of a solder ball at a lead terminal by covering an electronic component body in which the terminal is axially extended with an insulating sheath, heating it at a temperature of a melting point or higher of solder, feeding excess solder of a base end out of the sheath, and then bending the terminal along the sheath. ;CONSTITUTION: An inductor body 1 is formed by winding a winding 3 on a drum-shaped core 2, binding its end 4 with a base ends of lead terminals 7, 7 fixed in recesses 5, 5 formed on both end faces of the core 2 with adhesive 6 and conductively fixing with solder 8. An insulator of resin including the base end is covered with insulating sheath 9 by molding. Then, excess solder 8 of the base end of the terminal 7 is fed externally between the terminal 7 and the sheath 9, and so covered as to become a thin layer by extending toward the outer end of the terminal 7. Thereafter, the terminal 7 is bent along the sheath 9.;COPYRIGHT: (C)1994,JPO&Japio
