PURPOSE:To reduce the number of manufacturing steps and to improve the rate of yield by a method wherein an adhesive agent thermosetting mechanism is additionally provided capable of transporting a lead frame after pellet mounting. CONSTITUTION:A lead frame handling section 9, after detecting the completion of pellet mounting onto a paste-applied lead frame 14, handles the lead frame 14 into a stage 8. The lead frame 14 synchronized with a feeding section 11 is sent into a heater unit 3, heated while travelling along a heater block 10, and accommodated in a housing section 12. When the index time per pellet in the heating unit 3 is not longer than that in a die-bonder 1, the intermediate stage 8 keeps the die-bonder 1 and the heating unit 3 from mutual interference. This in turn enables a fine trimming of heating time, preventing die-bonder serviceability deterioration that may otherwise be present due to improper line balancing. |
