Patent JP-H09186188-A (JP)
Title: Wire bonding apparatus
Inventor: NAKAO MITSUHIRO
IPC: H01L21/60
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce a required time for setting and adjusting conditions by calculating and indicating the diameter of a ball. SOLUTION: A ball diameter calculator 16 receives a signal a indicating the diameter of a thin metal wire, signal d indicating a target value of the diameter of a ball, discharge current setting signal 9, output terminal voltage signal depending on the voltage value between output terminals 11 and 11a at the output of a high voltage detector 14a, and discharge start timing signal from a timing generator 12a and calculates the ball diameter on the basis of these input signals. An output signal of the calculator 16 is fed to a ball diameter indicator 17 to indicate the ball diameter. This eliminates the necessity for adjusting a bonding machine with repetition of settings of the discharge current and the time as well as measuring of the ball diameter by operators.  And, if the gap length, i.e., the distance between the metal wire and torch electrode changes, a ball of a fixed diameter can be always formed.

Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To compensate the fast variation by dividing an orthogonal frequency multiplex modulated signal into plural frequency bands and estimating the amount of phase variation due to the multipath fading by means of a guard section waveform for every frequency band. SOLUTION: A timing/frequency offset estimation part 31, a delay part 32 and a frequency compensator 33 cooperate with each other to compensate the fixed frequency offset between a transmitter and a receiver. The compensated reception signal is divided into the coherence band width degrees of a transmission line by the BPF 40, 41 and 42. A variation estimator 43 estimates the time variation of a fading transmission path, and a delay part 46 delays the signal by a time needed for the estimation. A variation compensator 51 compensates the time variation of the estimated signal. The compensated signal is divided into the signals for every subchannel by a 2nd discrete Fourier transformer 61, and a parallel/serial converter 64 converts the divided signals into the serial data. So are with other divided channels.  Then a digital demodulator 38 demodulates the signal that is multiplexed by a multiplexer 37.
