  • Patent number: 4644335
    Abstract: Acoustic transducers are attached to each of the drill bits which produce electrical output signals in response to the vibrations during the drilling operation. A plurality of output signal includes waveforms having an amplitude and frequency dependent upon the condition of the drill bit and the medium being drilled. The waveforms represent the acoustic signature produced by the drilling operation. A control unit simultaneously compares the acoustic signature of each of the output signals with a reference signal by comparing the waveforms to determine if an improper drill condition exits. When drilling through a multilayered workpiece such as a printed circuit board having layers of different types of materials, the acoustic transducers will produce an output signal having a sequence of waveforms representing the acoustic signatures of the sequence layers. The control unit counts the number of waveform occurrences for each particular type of layer and indicates when a predetermined level is reached.

  • Patent number: 4504727
    Abstract: A laser drilling control system utilizing photoacoustic feedback is described. The control system provides an accurate monitoring of the laser drilling of a multilayered printed circuit board thereby allowing uniform drilling through layers of different optical and photoacoustic properties by both analyzing the photoacoustic feedback signals received, and adjusting optimally the laser parameters such as pulse duration, wavelength, energy, pulse repetition rate, and the number of pulses, for each successive layer. The system also provides an end point detection which prevents underdrilling overheating, and overdrilling of underlying layers and associated damages. According to another aspect of this invention, the control system can be used as a sensitive misregistration detector for aligning the laser beam to a selected drill site for subsequent drilling at the selected drill site.
