Abstract:
The present disclosure relates to a machining station for machining platelike workpieces (1) by means of at least one tool, in particular a drilling station for machining at least one circuit board, as well as to a method for controlling or identifying a platelike workpiece (1). The machining station has at least one X-ray radiation source (3), at least one detector (4) and a table (2) that can be positioned between the X-ray radiation source (3) and the detector (4), on which the workpiece (1) to be machined can be fastened. The table (2) has a receiving plate (6) made out of a material permeable to X-rays (5), in particular a plastic. The receiving plate (6) has at least one suction port (11) for extracting air and a distribution grid, which is connected in terms of flow with the at least one suction port (11) and consists of several channels (10) unilaterally open in a support surface (9) with beveled and/or rounded edges (13) and/or of inclinedly running through openings (14).
Abstract:
A substrate position detection device includes: an irradiator that irradiates a predetermined range of a substrate with a predetermined light; an imager that takes an image of the predetermined range of the substrate irradiated with the predetermined light; a moving mechanism that causes a relative movement of the imager and the substrate; and a controller that: detects a position of the substrate by sequentially executing to a plurality of recognition objects on the substrate: a moving process of relatively moving the imager to a position corresponding to a predetermined recognition object among the plurality of recognition objects on the substrate; an imaging process of taking an image of the predetermined recognition object under a predetermined imaging condition; and a recognition process of recognizing the predetermined recognition object based on image data obtained by the imaging process.
Abstract:
Terminal portions are arrayed at regular widths and regular intervals, and each face any enable terminal, and are electrically connected to the enable terminals by conductive particles. A lead portion is connected to the other terminal portion except for a pair of terminal portions which is a pair of terminal portions adjacent to each other, and extends from an overlap region to a lead region. A connection portion connects the respective terminal portions that are not connected with the lead portion to the adjacent terminal portions that are connected to the lead portion within an area of the overlap region. An interval between a pair of lead portions extending from a pair of connection portions located to sandwich a pair of terminal portions that are not connected with the lead portion therebetween is larger than an interval between the other adjacent lead portions.
Abstract:
In a device for producing and/or processing a workpiece, in particular circuit boards, in a work station, in particular for printing a corresponding blank or for checking finished circuit boards, at least one mark is provided on the workpiece. In this arrangement, at least one reference, which can be brought into alignment with the mark, is provided in the work station.
Abstract:
A manufacturing method for a component incorporated substrate according to the present invention includes positioning an electronic component with reference to a mark formed on a copper layer, the mark consisting of a material less easily etched than copper by a copper etching agent used for etching of copper, after mounting the electronic component on the copper layer with an adhesive layer interposed therebetween, embedding the electronic component and the mark in an insulating substrate, thereafter, etching and removing a part of the copper layer to form a window for exposing the mark, forming an LVH reaching a terminal of the electronic component with reference to the exposed mark, electrically connecting the terminal and the copper layer via a conduction via formed by applying copper plating to the LVH, and, thereafter, forming the copper layer into a wiring pattern.
Abstract:
A method of achieving precision registration in a roll to roll process by simultaneously depositing multiple inks onto a printing roll. One of these inks prints a pattern of fiducial marks onto a substrate while another ink prints a predetermined pattern on the same substrate such that the predetermined pattern bears a predictable spatial relationship to the pattern of fiducial marks. Consequently, even if the ink forming the predetermined pattern is invisible, or has such low contrast with the substrate that it is effectively invisible, or even has been dissolved away in a subsequent processing step, it is still possible to know where the predetermined pattern is by referring to the pattern of fiducial marks.
Abstract:
A printed circuit board may include an aluminum nitride (AIN) substrate that includes an AIN thin film and a layer of high-frequency polymer as a carrier substrate of the AIN thin film. The AIN substrate forms a first layer of the printed circuit board. The AIN substrate comprises a heat spreader that laterally spreads out heat from a heat sink on the printed circuit board to form a thermal dissipation path parallel with a signal path on the printed circuit board. The printed circuit board may include a main substrate aligned to and bonded with the AIN substrate. The main substrate may include one or more additional layers of the printed circuit board.
Abstract:
A mounting structure in which a plurality of substrates are electrically connected to each other includes a first substrate having a first alignment mark formed by partially cutting away a first terminal, and a second substrate having a second alignment mark formed by partially cutting away a second terminal. The first terminal and the second terminal are electrically connected to each other by being relatively positioned with respect to each other.
Abstract:
For a method for producing a circuit board consisting of a plurality of circuit board areas, wherein the individual circuit board areas comprise at least one layer made of an in insulating base material and a conducting pattern located on or in, the base material, the following is provided: a substrate material, at least one registration mark formed in the substrate material, a first circuit board area arranged on the substrate material, at least one additional circuit board area, which substantially adjoins the first circuit board area or at least partially overlaps the first circuit board, the additional circuit board areas being oriented relative to the registration mark, and a plurality of connections of the conducting patterns of the first circuit board area and of the at least one additional circuit board area. Thus improved registration and orientation can be achieved when circuit board areas are coupled.
Abstract:
A PCB according to an exemplary embodiment of the present disclosure includes a plurality of unit PCBs arrayed on the PCB, and a sawing line formed among the plurality of unit PCBs. The sawing line disposed among the dummy unit PCBs is formed with a conductive pad including a first layer formed with a PSR (Photo Solder Resistor) and a second layer on which the PSR is removed to open the conductive pad. Burr generation on the unit PCBs during a sawing process is prevented and a dummy area can be reduced.
