Patent JP-S567443-A (JP)
Title: Wire bonder
Inventor: TANIGUCHI YUUZOU
IPC: H01L21/60
Filed: 1979-06-29
Abstract: PURPOSE:To provide a wire with fixed tension at all times even when a device is operated at high speed by a method wherein a clamper is used which a space between an attracting surface of an electromagnet and a surface to be attracted of a magnetic material in case of nonattraction is made slightly wider than the thickness of the wire. CONSTITUTION:A space between an attracting surface of an electromagnet 12 and a surface to be attracted of a magnetic material 13 in case of nonattraction is made slightly wider than the thickness of a wire 4, and both surfaces approximately contact to the wire closely. When switching the electromagnet ON, the magnetic material 13 is instantaneously attracted, and the wire 4 is clamped. When switching the electromagnet OFF, the tension of the wire is removed, and the wire is extracted to the bonding side from a capillary. Thus, the wire is provided with the desired tension at all times by switching the electromagnet ON-OFF. When the magnetic material 13 is hung by a string, etc. and moved in air, its responsiveness is far better than a movable plunger. Thus, wire bonding at high speed can be executed.

Therefore, the thermal insulative layer 1 is not formed under a proper condition of temperature, a dispersion in strength of the thermal insulative layer 1 and a poor strength of the thermal insulative layer are hardly occurred.

Abstract: PURPOSE:To prevent the damage of a magnetic tape by protruding the sloping part provided at the head part of the 2nd guide over the upper edge of the tape when the tape drawn out of the 1st tape guide is taken up to the 2nd guide during the loading and unloading processes. CONSTITUTION:A take-up roll 64 and an arm 79 move forward with turnings of a loading ring 71. Then the arm 79 slides to a stopper 78 to compress a spring 80 and presses the roll 64 to a catcher 82 when the rotary shaft 90 of the roll 64 touches a V-shaped groove 95 at the upper edge of the catcher 82 and the ring 71 has more turnings. The arm 79 bends with the reaction of the pressure of the spring 80, and therefore the height and the sloping angle of the roll 64 are prescribed. The upper edge of a magnetic tape 6 reaches an adverse truncated cone set at the head of the roll 64 as a base 63 goes up. Then the power is generated to push down the tape 6 via the taper of said truncated cone. Thus the tape 6 is moved down and driven at a correct position.
