Abstract
A ball forming method and device used in a wire bonding apparatus in which a discharge is caused to occur by applying a high voltage between an electric torch and a tip end of a wire that extends out of a lower end of a capillary so as to form a ball at a tip end of the wire, and an insulating member is provided so as to cover the electric torch with a space between the vicinity of a discharge portion of the electric torch and the insulating member, a heater being further provided on the insulating member so as to heat such a space.
Claims3
A ball formation method in a wire bonding apparatus in which a discharge is caused to occur by applying a high voltage between an electric torch and a tip end of a wire that extends out of a lower end of a capillary so as to form a ball at a tip end of said wire, wherein said discharge is performed in a state:
- in which a discharge portion of said electric torch is covered by an insulating member with a space formed between said discharge portion and said insulating member,
- in which said tip end of said wire is located outside of said insulating member, and
- in which said space is being heated by a heating means provided on said insulating member.
A ball forming device used in a wire bonding apparatus in which a discharge is caused to occur by applying a high voltage between an electric torch and a tip end of a wire that extends out of a lower end of a capillary so as to form a ball at a tip end of said wire, wherein said ball forming device is comprised of:
- an insulating member which covers said electric torch with a space formed between the vicinity of a discharge portion of said electric torch and said insulating member, and
- a heater provided on said insulating member so as to heat said space, and wherein
- a tip end of said wire is provided outside of said insulating member.
