Title:
AIR TENSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/077681
Kind Code:
A1
Abstract:
Disclosed is an air tension device, comprising a through tube (4), further comprising a through aperture (3), wherethrough a metallic wire-bonding wire (2) is capable of passing; a support body (6) whereupon the through tube (4) is inserted, and which thereby supports the through tube (4); and a pressurized gas supply apparatus (7), which supplies pressurized gas to the through aperture (3) via a gas channel (18) that is disposed upon the through tube (4). The through aperture (3) is formed from a first through aperture (10), and a second through aperture (11), which is positioned below the first through aperture (10) and further comprises a narrow aperture portion (17) that has a smaller diameter than first through aperture (10). The diameter of the narrow aperture portion (17) is 0.070-0.100mm, and is formed such that the ratio of the diameter of the first through aperture (10) to the diameter of the narrow aperture portion (17) is greater than or equal to 3.00 and less than 6.00. The apparatus thus avoids damaging the metallic wire (2) and applies a prescribed appropriate tension thereupon.
