Abstract:
A multilayer circuit board is provided, which includes multiple core boards stacked together. The core board includes an insulation layer and at least one conductor layer attached together. The conductor layer includes a circuit. The core board has at least one identification conductor disposed at an edge of at least one conductor layer. The identification conductor forms an identification pattern on a side surface of the core board along a stacking direction of the core boards. The identification patterns of the multiple core boards are different from each other on the side surface of the multilayer circuit board along the stacking direction of the core boards. A manufacturing method of the multilayer circuit board is further provided.
Abstract:
A pattern forming method includes: performing a first droplet ejection step by ejecting droplets containing 0.1%-2% polysiloxane by mass onto a substrate; performing a first layer forming step by solidifying the droplets ejected onto the substrate so that a first layer is formed; performing a second droplet ejection step by ejecting more droplets over the first layer; and performing a second layer forming step by solidifying the droplets ejected onto the first layer so that a second layer is formed.
Abstract:
A transferable film includes a carrier layer and an intermediate film portion. The carrier layer is configured to receive one or more additional layers and to be releasable from the one or more additional layers temporally proximate to an application of the transferable film to an object. The intermediate film portion includes a readable conductive image portion and is configured for application thereto of an adhesive layer. The intermediate film portion is configured to be interposed between the carrier layer and the adhesive layer, and the adhesive layer configured to adhere to the object for the application of the transferable film to the object.
Abstract:
An exposure device can exposes a circuit pattern while information data is suitably changed. An exposure device comprises a first light source (20) for irradiating a first light including ultraviolet rays, a projection exposure unit (70) for exposing a circuit pattern drawn on a photomask on a substrate, with the first light, a substrate stage (60) for mounting the substrate, a housing (11) for arranging the substrate stage, a second light source (41) for irradiating a second light including ultraviolet rays, arranged at a position different from the first light source, a spatial light modulation unit (40) for exposing information data formed electrically using the second light on the substrate, and a spatial optical light modulation unit driving means (5) for moving the spatial light modulation unit arranged on the housing (11) in a direction parallel to a moving direction of the substrate stage.

Abstract:
A circuit board to be attached to a support such as a case body is provided. The circuit board has formed therein a mounting hole which is so designed as to permit a thermally deformable stud to protrude through the mounting hole and also to be thermoplastically staked to mount the board to the support. A layer is printed on the board by means of silk screen printing at a distance from the mounting hole. In a case where a moisture-proof and insulating material is applied over a surface of the board, the printed layer servers to block a flow of the moisture-proof and insulating material into the mounting hole. This avoids a reduction in strength of fastening the board to the support. The printed layer may also be used in visually inspecting a failure in thermoplastic staking to mount the board to the support.
Abstract:
A method of fabricating packaging for a product comprises forming a plurality of conductive tracks on a sheet of material and forming a physical barrier, such as a hole, for impeding fluid flow between adjacent conductive tracks. The method may further comprise depositing first and second regions conductive fluid onto adjacent first and second conductive tracks either side of the physical barrier and mounting an electronic device having first and second terminals such that the electronic device forms a bridge over the physical barrier and the first ands second terminals contact the first and second conductive adjacent tracks.
Abstract:
A label assembly includes a support and a label body. The label body is configured to allow a label to be attached thereto. The support includes an upright post, and a fixing portion formed at a distal end of the post opposite to the label body. The fixing portion is configured to removably attach the label assembly to a circuit board. A circuit board supporting the label assembly is further provided.
Abstract:
In a wiring substrate in which plural wiring layers and insulating layers are alternately stacked and the adjacent wiring layers are electrically connected through a via hole formed in the insulating layer, plural holes constructing substrate management information recognizable as a character, a symbol, etc. are formed in the outside insulating layer of the insulating layers.
Abstract:
A method and system increase processed specimen yield in the laser processing of target material that includes multiple specimens formed on a common substrate. Preferred embodiments implement a feature that enables storage in the laser processing system a list of defective specimens that have somehow been subject to error during laser processing. Once the common substrate has been completely processed, the system alerts an operator to the number of improperly processed specimens and gives the operator an opportunity to run a software routine, which in a preferred embodiment uses a laser to scribe a mark on the top surface of each improperly processed specimen.
