Title: Winding of bonding wire
Inventor: KUBO TOSHIYUKI
IPC: B65H55/04
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent winding from collapsing and to increase the amount of the winding to enhance the workability of a bonding work by a method wherein the first layer of winding is wound on a spool in a prescribed length and at a prescribed winding pitch with the center of the winding surface of the spool as the center of a winding surface for the winding and the second and later layers are wound at a prescribed spreading pitch in such a way the width increase. SOLUTION: First, one layer of a gold wire 2 is wound on a spool in a prescribed winding length 1. Then, a gold wire 3 is wound on the gold wire 2. That is, the first layer gold wire 2 is wound on the spool in a prescribed length and at a prescribed winding pitch with the center of the winding surface of the spool as the center of a winding surface for the winding wires and the second and later layers of gold wires are wound in such a way as to wind-spread at a prescribed spreading pitch. In such a way, as the lower layer parts of the gold wires are surely covered with the upper layer parts of the gold wires, the gold wires hardly collapse even if there are a strong shock and vibrations when the spool is erected or during the carrying of the spool. Thereby, the winding amount of the gold wires is increased and the workability of a bonding work can be made to enhance.

CONSTITUTION:A sampling tube S containing a sample taken out of a molten metal is placed on supports 5 in a sample chamber 4, which is then enclosed and exhausted by a vacuum exhaustion pump 6 into a vacuum state equal to or lower than 10<-6>Torr. After confirming with a vacuum gauge 7 that the sample chamber has reached a given vacuum level, an electron beam of high energy density from an electron beam source 8 is narrowed down through a focus adjusting section and focused on an outer tube 1 of the sampling tube S to melt the tube, so that the hydrogen released at the time of solidification, which was collected in a vacuum part 2 of the sampling tube S, is released into the sample chamber 4. A change in hydrogen partial pressure within the sample chamber S is detected by a mass spectrometer 10 to measure a quantity of the hydrogen released at the time of solidification. Subsequently, the electron beam is adjusted to be focused on the surface of a solidified metal 3 and then irradiated to the metal, thereby to melt a part of the solidified metal 3. The hydrogen released from the molten metal is measured in quantity thereof in a similar way.

Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To improve light shielding property at the time of function trimming, by covering a semiconductor element on a thick film substrate, with a cap for light shielding. SOLUTION: The function trimming of a thick film resistor part is performed while the resistance value of a thick film resistor 4 is measured, by moving up and down a mounting stand on which a specimen is set, and bringing a probe pin 8 into contact with a pad part 7 for contact. By using the up-and- down movement, a light shielding cap 11 is pressed with a spring 10 fixed to a probe board 9, at the time of function trimming of thick film function. Thereby the semiconductor element 2 is subjected to light shielding. Adhesion of the cap 11 to the thick film substrate 1 is improved by previously coating the bonding surface of the thick film substrate 1 to the light shielding cap 11 with silicone rubber. Thereby accurate trimming is enabled, and dispersion of characteristics of a hybrid integrated circuit can be restrained, so that products of stable quality can be obtained.
