Abstract

PURPOSE:To prevent the faulty swelling of a clad material for a lead frame and obtain high yield by a method wherein a brazing material of Ag or an Ag alloy is rolled and pressure-welded on an IC lead frame substrate, and annealed at a specified temperature. CONSTITUTION:The brazing material 11 of Ag or an Ag alloy is rolled and pressure-welded on the IC lead frame substrate 10, and annealed at a temperature not more than 500 deg.C. For example, the IC lead frame substrate 21 in 42Ni and a brazing material sheet 20 in an Ag-Cu alloy are rolled and pressure-welded by means of a device shown in the figure at the normal temperature and at 30% rolling rate, and diffused and annealed at 400 deg.C, and the clad material is obtained.
