    摘要： A screen printing method is provided, in which a work time for changing machines is short and which is capable of highly accurately positioning fine patterns and narrow pitch patterns to perform screen printing. The method comprises finding an amount of movement of a circuit board from positions of recognition marks (2, 2) on the circuit board (1) and positions of recognition marks (5, 5) on a screen form plate (4), positioning the circuit board (1) relative to the screen form plate (4) on the basis of the amount of movement of the circuit board, detecting a discrepancy between an aperture pattern (18) and a land pattern (19) in a specified portion of the circuit board (1), finding a positional correction from the discrepancy, and positioning the circuit board (1) relative to the screen form plate (4) on the basis of the amount of movement of the circuit board and the positional correction.

    摘要： In a screen printing apparatus and a screen printing method, in which a printing paste on a screen is squeezed by a squeegee which is moved horizontally for printing and coating on a substrate, the squeegee is flexibly moved along the substrate, irrespective of inclination, waviness and warp of the substrate, to evenly perform printing under low, constant printing pressure to provide a highly accurate printing of good configuration. Thus an air cylinder (27), which is rotatable about the central position in a lenghtwise direction of squeegees (26a, 26b) and cancels a weight of the squeegees (26a, 26b), lifts the squeegees (26a, 26b), and then air cylinders (35, 36) disposed at symmetrical positions relative to the central position push down the squeegees (26a, 26b) to squeeze an upper surface of a screen (23).

    摘要： A screen printing method capable of preventing the drop of printing quality due to a jerky behavior of a screen resulting from the change-over operation between a going squeegee and returning squeegee. The going squeegee (2a) and the returning squeegee (2b) are equipped independently with an actuator (6a) for the going squeegee and an actuator (6b) for the returning squeegee, and the returning squeegee (2b) lowers at a standby position over a screen (1) and strikes the screen (1). Next, the going squeegee (2a) is raised and printing by the squeegee (2b) is conducted, so that the jerky behavior of the screen due to the squeegee switching can be restricted and quality of the printing shape can be improved.
