PURPOSE:To perform line junction efficiently, by making connection with element electrodes with ultrasonic waves and with leads by thermal pressing. CONSTITUTION:The cooling material 6 is closely mounted with the element mounting stand 4 on its surface, and it is hollow and has vent holes 6a' and 6a to prevent temperature rise of elements. The capillary 2 traverses with gold wire after ultrasonic welding of the gold wire 1 and moves to the upper direction of the lead ends. When the lead 5 is closely mounted on the upper surface of the heating material 7, no ultrasonic waves are required and connection can be made only with thermal pressing. With this method, the element performance can not be injured, no capillary choke is caused because of thermal pressing, and bonding can be made efficiently. |
