Patent number: 7350685Abstract: The method is capable of securely mounting an electronic component on a circuit board by applying ultrasonic vibration. The method comprises the step of applying ultrasonic vibrations to the electronic component so as to flip-chip-bond the electronic component to the circuit board having electrodes. Portions of the circuit board, which correspond to peaks of amplitude of vibrations transmitted to the circuit board, are pressed when the ultrasonic vibrations are applied to the electronic component.Type: GrantFiled: January 25, 2005Date of Patent: April 1, 2008Assignee: Fujitsu LimitedInventors: Takayoshi Matsumura, Hidehiko Kira, Kenji Kobae, Norio Kainuma

Publication number: 20080006674Abstract: An apparatus and method for detecting the oscillation amplitude of a bonding tool includes a sensing unit disposed adjacent to and at a distance from the bonding tool. The sensing unit includes a pair of electrodes, a piezoelectric sensing layer located between the pair of electrodes, and a membrane associated with the piezoelectric sensing layer. The piezoelectric sensing layer becomes sensitive to ultrasonic vibrations and generates electrical voltage signals after being activated by a poling process. An optional pre-amplifier is used to amplify the signals generated from the sensing unit, and an oscilloscope is used to further process the signals.Type: ApplicationFiled: July 5, 2006Publication date: January 10, 2008Inventors: Helen Lai Wa Chan, Tin Yan Lam, Chen Chao, Kin Wing Kwok

Publication number: 20080000944Abstract: An ultrasonic welder includes a housing having an ultrasonic transducer, a horn mounted to one end of the housing, a motor having a shaft, and a mounting assembly having a fastener such as a threaded screw. One screw end is coupled to the motor shaft to rotate as the motor shaft is being driven. The other screw end extends into a threaded screw receiver running within the housing. Upon rotating in one direction, the screw engages more threads of the screw receiver such that the housing with the horn move upward. Upon rotating in the other direction, the screw engages less threads of the screw receiver such that the housing with the horn mover downward. A linear transducer extends from the mounting assembly into the housing to monitor the horn position. A pair of guide shafts extend from the mounting assembly into the housing to stabilize the horn positioning.Type: ApplicationFiled: June 30, 2006Publication date: January 3, 2008Applicant: T.A.
