    Abstract: A method and associated structure for excising laminate chip carriers from a panel that has a thickness less than about 100 mils. A laser beam is focused on a surface of the panel, and the panel is moved relative to the laser beam in a geometric pattern, such that cells of the panel (e.g., chip carriers) are excised from the panel. The laser parameters include a wavelength between about 500 nanometers and about 600 nanometers, a pulse width greater than about 100 nanoseconds and less than about 350 nanoseconds, an average power of at least about 1 watt, a pulse repetition rate between about 5,000 pulses/sec and about 20,000 pulses/sec, and a target diameter (D) between about 2 microns and about 30 microns. The kerf width between adjacent excised cells is between about 2 microns and about 75 microns. The width of an excised cell is at least 5 mm. A displacement between successive pulses of the laser beam is less than about 2D. The panel may comprise a layered structure that includes an organic layer and a metal layer. The laser includes, inter alia, a lasant of Nd:YAG, Nd:YLF, Nd:YAP, or Nd:YVO4. The method of the present invention wastes less panel area by at least a factor of about 13 than does the mechanical excising techniques of the related art.

    Abstract: A method of fabricating a laminated circuit assembly and the assembly made therefrom including the steps of providing a relatively stiff substrate. A U-shaped slit is cut in the substrate in an area where a peripheral pull tab subsequently is to be located. The side legs of the U-shaped configuration define spaced slit portions. A relatively flexible backing sheet is adhered to a back side of the substrate. The laminated substrate and backing sheet are cut with a peripheral cut intersecting the side legs of the U-shaped slit, with the peripheral cut forming a pull tab projecting outwardly from the U-shaped slit. The pull tab can be grasped and separated from the substrate to strip the backing sheet therefrom.

    Abstract: A method of producing a semiconductor device of the present invention is applicable to a multilayer wafer for leadless chip carrier packages and breaks it on a package basis. The method begins with a step of forming a generally V-shaped groove in one major surfaces of the wafer in the direction of thickness of the wafer. A weak, cleaving portion is formed in the other major surface of the wafer in alignment with the groove. A cleaving force is exerted on the wafer to thereby form a break in the cleaving portion, so that the wafer is caused to break from the groove toward the cleaving portion in the direction of thickness of the wafer. The cleaving portion may be replaced with a strong, non-cleaving portion, in which case the break is formed in the interface between the non-cleaving portion and the wafer due to a difference in cleaving force.

    Abstract: Circuit boards are formed within the boundaries of an insulative sheet or panel such that the panel may be automatably processed. The periphery of each printed circuit board is defined by at least a plurality of score lines which do not extend to the edge of the sheets and may include also uncut and/or unscored areas to provide stability to either the sheet or segments of scrap material, lending rigidity to the sheet. Following complete fabrication of the printed circuit board, the sheet is cut by a routing process to extend selected score lines to the edges of the sheet to destroy the integrity of the frame of scrap material surrounding the printed circuit boards.
