  • MITIGATING EFFECTS OF CROSSTALK IN AN INKJET HEAD
    Publication number: 20170253028
    Abstract: Systems and methods of mitigating the effects of crosstalk in an inkjet head. An inkjet head has ink channels that jet droplets of a liquid material using piezoelectric actuators. Drive waveforms provided to the piezoelectric actuators include jetting pulses that cause activation of the piezoelectric actuators to jet the droplets from the ink channels. When crosstalk exists between the ink channels of the inkjet head due to the piezoelectric actuators, the amplitude of the jetting pulses are modified to mitigate the crosstalk between the ink channels.

  • Alignment support device and alignment support method for probe device
    Patent number: 9442156
    Abstract: The present invention provides a probe device that includes an alignment utility function. When a user inputs a condition value for a variation amount (variation range) of a contact position at which a probe is in contact with each chip, in a simulation using actual measurement data acquired by measuring a position of each of all chips in one wafer, a range of variation of each chip is calculated by changing a measurement point at which alignment is performed to calculate a setting of optimum measurement points so that the range of variation is equal to or less than the condition value and the number of measurement points is minimum. Then information on the optimum measurement point is provided to the user.
