Manufacturing method of plastic mask for paste printing, Plastic mask and paste printing method for paste printing

摘要

SUMMARY OF THE INVENTION An object of the present invention is a method of manufacturing a plastic mask for paste printing, which is excellent in filling performance of a paste into a through-opening portion in a pattern shape and a detachment of a paste from a through-opening portion, and in particular capable of high quality and high precision printing of a fine pattern, The plastic mask manufactured and the paste printing method using this plastic mask are provided.;The present invention also provides a plastic mask for paste printing excellent in antistatic and wear resistance of static electricity and a paste printing method using the plastic mask. In addition, a paste printing plastic mask and a paste using the plastic mask are made to minimize the warp of the ribs of the opening as much as possible, to prevent printing defects due to the warp of the ribs, and to prevent the rib proximal end from fatigue failure due to the repeated warpage. Provide a printing method. According to the present invention, the polymer film absorbing at least a portion of the excimer laser beam is brought into close contact with the beam irradiation surface of the plastic plate and then irradiated with the excimer laser beam from the beam irradiation surface. After the through opening is formed, a method of producing a plastic mask for paste printing, characterized in that the polymer film is removed, a plastic mask produced by this method, and a paste printing method using the plastic mask. The plastic mask for printing is characterized in that a conductive layer is formed on the back surface of the plastic mask plate in a plastic mask in a predetermined pattern on the plastic plate. Moreover, this plastic mask is used and paste printing method characterized by forming paste printing in the state which electrically conductive layer was grounded. A paste printing plastic mask having a through opening formed in a predetermined pattern on a plastic plate, wherein one or more connecting portions for reinforcing are formed in the slit-shaped opening in the opening, and Paste printing method using a plastic mask.
