Abstract:
METHOD OF DEPOSITING RESIST ON A CONTINUOUSLY MOVING WEB OF CONDUCTOR METAL FOIL BACKED BY FLEXIBLE DIELECTRIC MATERIAL WHEREIN A RESIST PATTERN IS DEPOSITED ON THE FOIL AT ONE STATION AND A DIFFERENT RESIST PATTERN IS DEPOSITED ON THE FOIL AT ANOTHER STATION, FROM WHICH WEB AN INDEFINITED LENGTH OF FLAT FLEXIBLE CABLE AND CIRCUITS IS FORMED BY ETCHING THE FOIL, THE SELECTION OF RESIST DEPOSITION BEING CONTROLLED BY SENSING OF PREVIOUSLY FORMED CONTROL INDICIA IN THE FORM OF OPENINGS, SUCH AS NOTCHES OR HOLES, LOCATED ALONG THE WEB AT A PREDETERMINED TRANSVERSE POSITION ON THE WEB.
Abstract:
A system and method for marking components of an assembly and/or portions of an assembly including at least one of the components with a plurality of markers, each component and/or portion including its own marker or markers, to be read in an operational sequence so as to generate at least one identifier representative of a characteristic and/or feature of the assembly. Any marker can be a certain type of marker, the combination of which can be used to generate an identifier. A certain type of marker 1 need not be dedicated to a certain component. Each marker can be associated with a proxy value, which can be obtained by reading the marker with a reader. An identifier of the assembly can then be generated by employing a predetermined sequence of reading the markers.
Abstract:
A circuit card is disclosed. The circuit card may have a strain relief aperture and a conductor contact. A conductor may extend through the strain relief aperture and connect in electrical continuity with the conductor contact. The circuit card may have a conformal coating, such as poly(p-xylylene) polymer applied. The conformal coating may be applied in layers, and the layers may have different thicknesses.
Abstract:
A light emitting device (10) includes light emitting elements (12), conductor wirings (14), and alignment marks (18) formed on a substrate (11). The alignment marks (18) and the conductor wirings (14) are formed by printing.
Abstract:
A flexible printed circuit board having a copper foil character with good visibility and without copper foil pattern peeling. The flexible printed circuit board has a base material having optical transparency, a wiring pattern formed on one surface of the base material; a first opaque cover lay film covering a surface of the wiring pattern, a character formed on the other surface of the base material; and a second opaque cover lay film covering a surface of the character. The first opaque cover lay film has an opening portion is formed therein, and the character is formed so as to be visually recognizable through the opening portion.
Abstract:
A printed circuit board (PCB) includes a stack of core layers disposed one over another, and electrically conductive interconnects extending vertically in the stack. Each of the core layers includes a substrate having opposite major surfaces, an electrically conductive active trace extending along at least one of the major surfaces, and an indicium. The stack also has an exposed edge where the indicia of the layers are together revealed. The indicia provide identifying and/or fiducial information about the PCB.
Abstract:
According to the present application, a printing unit is provided. The printing unit may include a first print head, a second print head, a UV pinning light source between the first print head and the second print head and a UV curing light source on an outer side of one or the other of the first print head and second print head. A printing apparatus of the type that uses liquid ink for printing on the surfaces of printed circuit boards is also provided. With the present application, it is possible to print high resolution images in one single pass.
