20120216690 | MASK FOR SCREEN PRINTING, SCREEN PRINTING DEVICE AND SCREEN PRINTING METHOD EMPLOYING SAME - The screen printing mask is used for printing paste simultaneously on circuit boards held by the carrier. The mask has a flat mask plate. On the lower surface of the mask plate, a flat-bottomed recess capable to accommodating at least one of the circuit boards is formed so as to correspond to the array of the circuit boards on the carrier. A pattern hole is formed only in the recess. | 08-30-2012 |
20130057676 | COMPONENT MOUNTING METHOD AND COMPONENT MOUNTER - A component mounting method includes: identifying, by image processing, a dark color region from image data obtained by imaging a two-dimensional region including a pickup face of a component to be picked up; deriving position data indicating a position of the identified dark color region; and deriving, based on the derived position data, a pickup position indicating a position at which a nozzle picks up the component. The imaging is performed by an imaging unit, and the dark color region indicates a dark color portion between electrodes of the component. | 03-07-2013 |
20130089239 | METHOD OF DETERMINING SOLDER PASTE HEIGHT AND DEVICE FOR DETERMINING SOLDER PASTE HEIGHT - A method of determining a solder paste height of solder paste printed on a circuit board, the method including obtaining a two-dimensional image of the circuit board which is captured from above a solder printed surface, and determining the solder paste height corresponding to a pixel value of each of pixels of the two-dimensional image, based on height information which defines a relationship between the pixel value and the solder paste height, the pixel value being a value representing at least one of luminance of red in a RGB color model, luminance of green in the RGB color model, luminance of blue in the RGB color model, hue in a HSI color model, saturation in the HSI color model, and intensity in the HSI color model. | 04-11-2013 |
20130239830 | SCREEN PRINTING DEVICE AND SCREEN PRINTING METHOD - At the two ends of a pair of clamping members ( | 09-19-2013 |
20140102322 | SCREEN PRINTING MACHINE, AND SCREEN PRINTING METHOD - A printing operation is repeatedly performed with respect to one substrate | 04-17-2014 |
20140318394 | SCREEN PRINTING MACHINE AND SCREEN PRINTING METHOD - In a screen printing that shifts squeegees in a horizontal direction while abutting the squeegees against a mask, and slides the squeegees on the mask, and scrapes up the paste on the mask so that opening portions are filled with the paste to transfer the paste onto the substrate, a larger amount of paste Ps is supplied to regions in which the paste is scraped up by the end portions of the squeegee than a region in which the paste is scraped up by a center portion of the squeegee on the mask. | 10-30-2014 |
20150129641 | SCREEN PRINTING MACHINE, ELECTRONIC COMPONENT MOUNTING SYSTEM, AND SCREEN PRINTING METHOD - A screen printing machine for forming a print of paste supplied to a mask plate having pattern holes, includes: a flexible filling squeegee which performs a squeegeeing operation in which the filling squeegee is moved relative to the mask plate in a printing direction; and a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction and to be movable together with the filling squeegee in the printing direction, and which scraps off the paste remaining on the mask plate after passage of the filling squeegee. In the squeegeeing operation, the filling squeegee is pushed up and bent by the paste to provide a clearance between a bottom end of the filling squeegee and the mask plate with the paste interposed therebetween so that the pattern holes are filled with paste with a prescribed filling pressure. | 05-14-2015 |
20150216058 | SCREEN PRINTING APPARATUS, ELECTRONIC COMPONENT MOUNTING SYSTEM AND SCREEN PRINTING METHOD - A screen printing apparatus includes a substrate positioning part that upwardly and downwardly moves a substrate with the substrate clamped by a clamp member to thereby bring the substrate into contact with a mask stretched in a frame body and fixed in a predetermined height position from an underside of the mask and position the substrate in a predetermined height position, a mask suction part that is provided in the clamp member and sucks the mask in contact with the substrate, and a screen printing part that prints paste on the substrate through a pattern hole formed in the mask by sliding a squeegee on the mask to which the paste is supplied. The mask is pressed up by a predetermined amount through the substrate with the mask sucked by the mask suction part when the substrate is upwardly moved by the substrate positioning part. | 07-30-2015 |
