Abstract:
A circuit board with identifiable information and a method for fabricating the same are proposed. At least one insulating layer within the circuit board has a non-circuit area free of a circuit layout. A plurality of openings are formed in the non-circuit area of the insulating layer. A patterned circuit layer is formed on the insulating layer. Metal identifiable information is disposed in the openings of the non-circuit area. By this arrangement, a product status of the circuit board can be traced and identified via the metal patterned information.

A method and apparatus include providing a printed circuit board (PCB) having at least one light permeable layer, at least one non-light permeable layer having at least one void therethrough that may be vertically aligned with the at least one light permeable layer, and a source of illumination to simultaneously illuminate through the void and the at least one light permeable layer.
Abstract:
A circuit board (205) for a valve block (120) of a solenoid valve manifold is described. Each valve block (120) contains a valve which is actuated by either one single solenoid or by two solenoids. Both sides (210, 220) of the circuit board (210) are provided with a circuit (212, 222). The first surface (210) of the circuit board (205) carries a single type valve circuit (212) for supplying one single solenoid with electrical energy. This first surface (210) can be mark e.g. with an “S”. The second surface (220) of the circuit board (205) carries a double-type valve circuit (222) for supplying two solenoids with electrical power. This second surface (220) can be marked e.g. with a “D”. The circuit board (205) is positioned in the respective valve block (120) with the first surface (210) or the second surface (220) facing upwards depending on whether a single- or a double-solenoid-valve is used in the respective valve block (120).

Abstract:
An exemplary PCI interface card includes a printed circuit board having a plurality of testing points arranged thereon, and a connecting portion configured to engage in a PCI connector of a motherboard. The connecting portion protrudes from the printed circuit board, and has a plurality of golden fingers disposed thereon. Some of the golden fingers configured to respectively connect with contacts of the PCI connector, which are set to connect with a south bridge chip of the motherboard to transmit address and data signals, are respectively electronically connected to the testing points of the printed circuit board.
Abstract:
A printed circuit board on which multiple component-dedicated alignment line indicators including parallel lines may be used to facilitate the evaluation and segregation process during the production of printed circuit board assemblies based on the alignment characteristics of mounted disk drive electrical components with respect to these parallel lines. Each electrical component defines a perimeter with edges defining a first and second lateral distances and corners defining a diagonal distance. The alignment line indicators include first and second inner line segments spaced apart a first inner spacing at least the first lateral distance and less than the diagonal distance. The alignment line indicators include third and fourth inner line segments spaced apart at least the second lateral distance and less than the diagonal distance. The alignment line indicators include first and second outer line segments spaced apart more than the first inner spacing and less than the diagonal distance.
Abstract:
The invention discloses an identifiable flexible printed circuit board (PCB) and a method of fabricating the same. The identifiable flexible PCB includes a flexible substrate, a conductive layer, and a printing ink layer. First, the conductive layer is formed over a surface of the flexible substrate. Second, the printing ink layer is formed on the surface of the flexible substrate by coating, exposing, and developing to uncover parts of the conductive layer. Also, at least one identifiable area is formed on the printing ink layer and one can easily and correctly identify the cartridge with the flexible PCB.
Abstract:
Information regarding electrical components and their use is provided with a foldable information sheet having instructions thereon. The sheet has apertures which fit over the electrical components and information is printed on the sheet in proximity to the electrical component or components to which it applies. A portion of the information sheet may be adhered to a planar surface on which the components are mounted and non-adhered portions of the information sheet may be folded over the components.
