摘要： A burst of ultrashort laser pulses is employed to sever a conductive link (22) in a nonthermal manner and offers a wider processing window, eliminates undesirable HAZ effects, and achieves superior severed link quality. The duration of the burst is preferably in the range of 10 ns to 500 ns; and the pulse width of each laser pulse within the burst is generally shorter than 25 ps, preferablyshorter than or equal to 10 ps, and most preferably about 10 ps to 100 fs or shorter. The burst can be treated as a single "pulse" by conventional laser positioning systems (62) to perform on-the-fly link removal without stopping whenever the laser system (60) fires a burst of laser pulses at each link (22). Conventional wavelengths or their harmonics can be employed.
摘要翻译：采用一阵超短激光脉冲以非热方式切断导电链路（22），并提供更宽的处理窗口，消除不希望的热影响区效应，并实现卓越的切断链路质量。突发的持续时间优选在10ns至500ns的范围内; 并且脉冲内的每个激光脉冲的脉冲宽度通常小于25ps，优选小于或等于10ps，并且最优选大约10ps至100fs或更短。通过传统的激光定位系统（62），突发可被视为单个“脉冲”，以在激光系统（60）在每个链路（22）处发射激光脉冲时不停止地执行即时链路移除。可以采用常规波长或它们的谐波。

摘要： A method of forming a scribe line (36) having a sharp snap line (44) entails directing a UV laser beam (14) along a ceramic or ceramic-like substrate (10) such that a portion of the thickness (24) of the substrate (10) is removed. The UV laser beam forms a scribe line in the substrate in the absence of appreciable substrate melting so that a clearly defined snap line forms a region of high stress concentration extending into the thickness of the substrate. Consequently, multiple depthwise cracks propagate into the thickness of the substrate in the region of high stress concentration in response to a breakage force applied to either side of the scribe line to effect clean fracture of the substrate into separate circuit components. The formation of this region facilitates higher precision fracture of the substrate while maintaining the integrity of the interior structure of each component during and after application of the breakage force.
摘要翻译：形成具有尖锐捕捉线（44）的划痕线（36）的方法需要沿着陶瓷或陶瓷状衬底（10）引导UV激光束（14），使得一部分厚度（24）的去除衬底（10）。 UV激光束在没有明显的衬底熔化的情况下在衬底中形成划线，使得清晰限定的咬合线形成延伸到衬底厚度的高应力集中区域。因此，响应于施加到划线的任一侧的断裂力，多个深度裂纹在高应力集中区域中传播到基板的厚度中，以使基板清洁断裂成单独的电路部件。该区域的形成促进了基板的高精度断裂，同时在施加破损力的同时保持了每个部件的内部结构的完整性。

摘要： A laser-based drilling technique provides a microporous filter (10) having very small holes (30, 30') with known diameters and locations. One embodiment of the technique entails using a laser beam (62) with one or more uniform spot sizes to form each hole. The laser beam ablates material depthwise for corresponding known distances into a substrate (12) to form a desired number of hole steps (32, 38, 44) in each hole. Another embodiment of the technique entails using an imprint patterning toolfoil (80) to stamp in the substrate depressions (32, 38) of specified diameters and distances that correspond to the hole steps. In both embodiments, a laser beam of Gaussian shape removes the last portion of material to form a very small diameter final hole step (44).

摘要： Terminating the ends of passive electronic components entails applying a laser-ablative coating (70) to each of the opposed major surfaces (14 and 16; 36 and 38) of a substrate (10 and 34). A UV laser beam having a spot size and an energy distribution sufficient to remove the laser-ablative coating from multiple selected regions of the major surfaces is directed for incidence on the substrate. Relative motion between the UV laser beam and substrate effects removal of sufficient amounts of laser-ablative coating to expose the multiple selected regions of the opposed major surfaces. The substrate is then broken into multiple rowbars (48 and 50), each of which includes side margins (60 and 62) along which are positioned different spatially aligned pairs of the selected regions of the opposed major surfaces. An electrically conductive material is applied to the side margins to form electrically conductive interconnects (56 and 58) between each spatially aligned pair of the selected regions.

摘要： Terminating the ends of passive electronic components entails applying a laser-removable coating (70) to one or both of the opposed major surfaces (14, 16; 36, 38) of a substrate (10, 34). A UV laser beam having a spot size and an energy distribution sufficient to remove the laser-removable coating from multiple selected regions of at least one of the major surfaces to which the laser-removable coating was applied is directed for incidence on the substrate. Relative motion between the UV laser beam and substrate effects removal of sufficient amounts of laser-removable coating to expose the multiple selected regions. The substrate is then broken into multiple rowbars (48, 50, 98) or individual components (100), each of which includes side margins. An electrically conductive material is applied to the side margins to form electrically conductive interconnects (56, 58, 96) between portions of the side margins spatially aligned with the multiple selected regions.

摘要： A laser beam (102) cuts through a component carrier mask (96) made of thin elastomeric material such as silicone rubber to form slots (98) having slot openings of a desired shape. In a preferred embodiment, a light absorptivity enhancement material such as iron oxide introduced into the silicone rubber causes formation of a flexible support blank that operationally adequately absorbs light within a light absorption wavelength range. A beam positioner (106) receiving commands from a programmed controller causes a UV laser beam of a wavelength that is within the light absorption wavelength range to cut into the mask multiple slots with repeatable, precise dimensions. Each of the slots cut has opposed side margins that define between them a slot opening of suitable shape to receive a miniature component (10) and to exert on it optimal holding and release forces.
