Oct 2, 2019

Appl. No.:

17/272155

Inventors:

- Portland OR, US
Jan Kleinert - Portland OR, US
Zhibin Lin - Portland OR, US

International Classification:

B23K 26/382
B23K 26/402
B23K 26/0622

Abstract:

A method for forming a through-via in a substrate having opposing first and second surfaces can include directing a focused beam of laser pulses into the substrate through the first surface of the substrate and, subsequently, through the second surface of the substrate. The focused beam of laser pulses can have a wavelength to which the substrate is at least substantially transparent and a beam waist of the focused beam of laser pulses is closer to the second surface than to the first surface. The focused beam of laser pulses is characterized by a pulse repetition rate, a peak optical intensity at the substrate and an average power at the substrate sufficient to: melt a region of the substrate near the second surface, thereby creating a melt zone within the substrate; propagate the melt zone toward the first surface; and vaporize or boil material of the substrate and located within the melt zone.

International Classification:

B23Q 15/14
G05B 19/19
G05B 19/402

Abstract:

One embodiment of the present invention can be characterized as a method for controlling a multi-axis machine tool that includes obtaining a preliminary rotary actuator command (wherein the rotary actuator command has frequency content exceeding a bandwidth of a rotary actuator), generating a processed rotary actuator command based, at least in part, on the preliminary rotary actuator command, the processed rotary actuator command having frequency content within a bandwidth of the rotary actuator and generating a first linear actuator command and a second linear actuator command based, at least in part, on the processed rotary actuator command. The processed rotary actuator command can be output to the rotary actuator, the first linear actuator command can be output to a first linear actuator and the second linear actuator command can be output to a second linear actuator.

Abstract:

Apparatus and techniques for laser-processing workpieces can be improved, and new functionalities can be provided. Some embodiments discussed relate to processing of workpieces in a manner resulting in enhanced accuracy, throughput, etc. Other embodiments relate to realtime Z-height measurement and, when suitable, compensation for certain Z-height deviations. Still other embodiments relate to modulation of scan patterns, beam characteristics, etc., to facilitate feature formation, avoid undesirable heat accumulation, or otherwise enhance processing throughput. A great number of other embodiments and arrangements are also detailed.
