MANUFACTURE OF ELECTRONIC PART

摘要

PURPOSE: To perform soldering by using cream solder in a short time and with less energy by moving an electronic part element assembly through the inside of an induction heating equipment under a condition where a lead terminal touches an electrode portion via cream solder. CONSTITUTION: A silver electrode 1a is formed on both the surfaces of a ceramic electronic part element assembly 1 constituted by a varistor sintered body having zinc oxide as main component. Cream solder 2 is screen-printed on this silver electrode 1a and is dried. Flat plate-shaped lead terminals 3 clamp both the surfaces and are temporarily bonded together under pressure; and cream solder 2 is melted by passing through an induction heating equipment and the lead terminal 3 is soldered to the silver electrode 1a. By doing this, working time can be shortened and the amount of energy used can be reduced.
