摘要： 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.

摘要： A screen printing apparatus is designed so that cream solder 17 disposed on a mask plate 12 can be preserved at a certain appropriate temperature by the limited use of blown air. An air nozzle unit 20 is provided above the mask plate 12 at a place on the side edge running in parallel with the moving direction of a squeegee 16. The temperature-conditioning air is blown sidewise from the air nozzle unit 20 towards the cream solder 17 during the operation of printing the cream solder 17 on the surface of a substrate through the mask plate 12 disposed in contact therewith.

摘要： In a screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate, a predetermined measuring position of the mechanisms in the screen-printing apparatus is measured three-dimensionally by a three-dimensional measuring device. Based on the measured result, a predetermined measuring point on an object to be measured is determined on a position relative to the origin of the mechanical coordinate system in the screen-printing apparatus, and the origin position on a control program can be set. As a result, machine adjusting operation and teaching operation in the screen-printing apparatus can be simplified with high accuracy.

摘要： There is disclosed a solder paste screen printing apparatus and a solder paste screen printing method, in which a force of pressing of a squeegee can be adjusted delicately and accurately so as to effect the printing of solder paste with the optimum pressing force. A squeegee is connected to a lower end of a rod of a cylinder, and a load cell is provided above the rod. A first pressure and a second pressure are applied respectively to an upper chamber and a lower chamber of the cylinder. A load, applied to the load cell, is measured while varying the level of the first pressure, and the pressure measurement for the pressing force is effected in accordance with the measured load. In accordance with this result, the instruction pressure for the cylinder, which is necessary for obtaining the optimum pressing force, is determined, and then the printing of solder paste onto a substrate is started with this instruction pressure.

摘要： A screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate. A laser-measuring device mounted in the apparatus measures the top surface of the screen mask at a printing position and the top of the substrate at a substrate-measurement position by three-dimensional measurement, and detects a shape of the substrate or the screen mask, and determines whether or not they are acceptable. After screen printing is completed, the substrate and the screen mask undergo a printing inspection where their shapes are inspected. This provides not only inspection data of the printing results but also data for identifying the causes of print failures. As a result, the screen-printing apparatus, which has high-printing accuracy and can prevent printing failures from occurring, is provided.
