PURPOSE:To bond leads onto a substrate while retaining the flatness of the ends of the leads and uniform interval of the leads by retaining the ends of the leads to be bonded with removable lugs. CONSTITUTION:Leads 2b-5b are bent in reverse direction to lugs 2a-5a. A frame 1 is placed on a ceramic plate 7, and adhered thereto with adhesive glass 8. When the substrate 7 is then passed between rollers 9 and 7, the lugs 2a-5a make contact with the roller 9 to be thus returned downwardly. Since notches 2d-5d are cut between the lugs and the leads, the lugs 2a-5a are cut and isolated and removed from the simple substrate 7 to complete the mounting of the leads 2b-5b onto the substrate 7. The ends of the leads are flat, and the interval among the leads is retained uniformly. |
