Abstract:
When a laser beam is incident on a thin film, carbide generated by the heat of the beam is not ejected between respective metallic thin plates. In each of second conductive sections of a metallic thin plate, a slit extends from a welding position to the end of the second conductive section. The second conductive sections are respectively welded to terminals by making the laser beam incident on the respective welding positions of a substrate for the thin film. Thereby, when the beam is incident on a resin, the resin is carbonized by the thermal energy of the laser beam and the resin carbide is ejected from the welded portion, and the carbide is discharged to the outside from the lower end of the second conductive section via the slit of the second conductive section. Thereby, the carbide is not ejected between the adjacent second conductive sections. Consequently, lowering of the insulation resistance between the respective second conductive sections due to the carbide is prevented.

The printed wiring board 1 includes the metallic substrate 2, the insulating layer 3 provided on the surface of the metallic substrate 2, and the conductive layer 4 formed on the surface of the insulating layer 3. The conductive layer 4 is electrically connected to the metallic substrate 2. A bottomed via hole or a through hole 6 is formed in the insulating layer 3 and the conducive layer 4. The via hole has a bottom in the metallic substrate 2, and has a wall surface in the insulating layer 3 and in the conductive layer 4. The through hole 6 extends through the insulating layer 3, the conductive layer 4, and the metallic substrate 2. Conductive paste 7 fills the bottomed via hole or the through hole 6 to electrically connect the metallic substrate 2 and the conductive layer 4 with each other. The printed wiring board 1 is subjected to a process in which current is applied to the interface between the metallic substrate 2 and the conductive paste 7.
Abstract:
Fine conductor lines (those having a width of ≦50 μM) are disposed on a flexible metal oxide containing substrate by masking portions of the substrate, and then surface metallizing unmasked portions of the substrate. Polymeric preceramic films are preferred, especially those having a glass temperature of at least 300° C. and those of the PZT family, or those containing BeO. All suitable reducing gasses are contemplated, including especially H2. All suitable masking materials are similarly contemplated, including especially titanium, titanium nitride, tungsten nitride, tantalum, and tantalum nitride. In especially preferred embodiments the conductor lines have a width of ≦25 μM, ≦15 μM, ≦5 μM, and even ≦1 μM. The lines can advantageously compose a circuit that is coupled to a piezoelectric or other mechanical actuator, which in turn can be fluidly coupled to a fluid reservoir.
