Abstract: A component mounting station is divided into two component mounting areas in a board conveyance direction according to the size of circuit boards used in two types of production that are performed in order, and the area in which a backup pin is arranged on a backup plate is divided into two pin arrangement areas corresponding to the two component mounting areas. The quantity of backup pins necessary to support the component mounting board are arranged in a predetermined arrangement pattern, the circuit boards transported using the conveyor are stopped in the component mounting areas according to the type of component mounting board produced, the backup plate is lifted up, and the circuit boards are clamped by the clamp member, and the circuit boards supported by the backup pins in the pin arrangement areas are positioned below the circuit boards, and components are mounted on the circuit boards.

Abstract: A revolving nozzle station and a revolving drive device that revolves the revolving nozzle station are housed inside a cassette case of a cassette-type nozzle exchanging unit. In an outer circumferential portion of the revolving nozzle station, multiple nozzles for exchange with a nozzle of component mounter are arranged radially along a revolution path, and the nozzles are held in a detachable manner. A nozzle exchange port is formed in a top end surface of cassette case, and nozzle exchange is performed between the revolving nozzle station and a mounting head of the component mounter through the nozzle exchange port. A shutter mechanism which opens and closes the nozzle exchange port is provided in the cassette case.

Abstract: A component mounting machine moves a mounting head from a supply position P1 to each of mounting positions P3 and P4 of a circuit board CB via an imaging position P2. Further, the component mounting machine performs control such that the mounting head moves in a direction of movement at the time of imaging that is either of an X-axis direction or a Y-axis direction when passing through the imaging position P2. The component mounting machine determines the direction of movement at the time of imaging, according to a first X-axis distance Lx and a first Y-axis distance Ly from the imaging position P2 to each of the mounting positions P3 and P4.

Abstract: The component mounting device determines suction deviation (posture change) of the component from after suction of the component until prior to mounting of the component based on an immediately post-suction image which is acquired by imaging the suction nozzle from the side immediately after suction of the component and an immediately pre-mounting image that is acquired by imaging the suction nozzle from the side immediately prior to mounting of the component.

Abstract: A soft back-up pin state checking device including a soft back-up pin formed of a bottom-side holder portion, and a top-side soft pin portion which is held by the holder portion in an exchangeable manner. A ring-shaped background portion which is possible to be distinguished from the soft pin portion and be recognized using image processing is provided on a top end surface of a cylindrical fitting portion which is outside of an outer circumference of the soft pin portion in the holder portion of the soft back-up pin.

Abstract: A board work device provided with mounting head that performs work with respect to a circuit board, slider on which the mounting head is mounted, moving device that moves the slider to any position, and support pin gripping device for gripping support pins which is provided on the slider on the opposite side to the side on which the mounting head is mounted.

Abstract: A mounting machine acquires identification information arranged in a back-up plate, from the back-up plate. The mounting machine controls a conveyance unit so as to change a conveyance lane based on mounting conditions when the acquired identification information is identification information which is included in the mounting conditions of a printed circuit board. Meanwhile, in the mounting machine, when the acquired identification information is not the identification information which is included in the mounting conditions of the printed circuit board, the conveyance lane is stopped from being changed. In this manner, a conveyance width of the conveyance lane is not changed when the back-up plate which is ready to be subjected to mounting processing and matches the mounting conditions is not mounted.

Abstract: This invention provides an engine cleaning composition for removing sediment formed in an engine. Such engine cleaning composition comprises: a dispersant containing a carboxylic acid and an amine; a chelating agent; a glycol solvent; and a naphthenic oil.

Abstract: The present invention provides a resin sheet that exhibits a small reduction in light reflectance due to a heating treatment and a light irradiation treatment with an excellent heat resistance being maintained. The present invention provides a resin sheet including a layer including a resin composition containing an aliphatic epoxy-modified silicone compound (A), a branched imide resin having an isocyanurate group and a carboxyl group (B), titanium dioxide (C) and a wetting and dispersing agent (D).

Abstract: A component mounter which picks components which are stored in tape and supplied from a component supply device by a component picking device and mounts components on a board which is conveyed by a board conveyance device including a waste box which stores the cut tape after the components are picked, a scraping out device which can scrape the tape out of the waste box, and a control device which controls scraping out the stored tape by the scraping out device when the tape is stored in the waste box to a predetermined amount.

Abstract: Provided are a resin composition that can realize a prepreg, a metal foil-clad laminate and the like high in light reflectance in an ultraviolet region and in a visible light region, small in the reduction in light reflectance due to a heating treatment and a light irradiation treatment, good in peel strength of metal foil, also excellent in heat resistance after moisture absorption, also good in outer appearance, and also excellent in preservation stability, and a prepreg, a metal foil-clad laminate and the like using the same. The resin composition of the present invention contains at least an epoxy-modified silicone compound (A), a branched imide resin (B) having an isocyanurate group and a carboxyl group, a phosphorus curing accelerator (C), titanium dioxide (D) and a dispersant (E).
