Abstract
A wire bonding method includes: arranging a first core including a plurality of strands exposed from an insulating sheath of a first wire, onto a side of an anvil and a second core including a plurality of strands exposed from an insulating sheath of a second wire, onto a side of a horn for ultrasonic bonding, the second core being larger in sectional area than the first core; and bonding the first core and the second core together by ultrasonic bonding between the horn and the anvil.
Claims5
A wire bonding method comprising:
- arranging a first core including a plurality of strands exposed from an insulating sheath of a first wire, onto a side of an anvil for ultrasonic bonding and a second core including a plurality of strands exposed from an insulating sheath of a second wire, onto a side of a horn for ultrasonic bonding, the second core being larger in sectional area than the first core;
- and
- bonding the first core and the second core together by ultrasonic bonding between the horn and the anvil.
A bonded wire comprising:
- a first wire having a first core including a plurality of strands exposed from an insulating sheath of the first wire;
- and
- a second wire having a second core including a plurality of strands exposed from an insulating sheath of the second wire, the second core being larger in sectional area than the first core, wherein
- the first core and the second core are bonded together by ultrasonic bonding between a horn and an anvil for ultrasonic bonding with the second core arranged on a side of the horn and the first core arranged on a side of the anvil, and
- the plurality of strands of the second core on the side of the horn is bonded with collapse stronger than collapse of the plurality of strands of the first core on the side of the anvil.
