Patent ID: 8720331

Claim:
A screen printing device that performs screen printing to a circuit board in which an upper-layer board member is bonded to an upper surface of a lower-layer board member on a first electrode pattern formed on an upper surface of the upper-layer board member and a second electrode pattern formed on the upper surface of the lower-layer board member that is bottom surfaces of openings disposed in a part of the upper surface of the upper-layer board member, in the circuit board in which the upper-layer board member is bonded to the upper surface of the lower-layer board member, the screen printing device comprising: a mask member which has a second electrode pattern corresponding mask region where a second electrode pattern corresponding mask pattern corresponding to the second electrode pattern is formed on bottom faces of fitting portions to be fitted into the openings of the upper-layer board member, and a first electrode pattern corresponding mask region where a first electrode pattern corresponding mask pattern corresponding to the first electrode pattern is formed as separate regions; and print executing means which performs positioning between the second electrode pattern corresponding mask region of the mask member and the second electrode pattern of the circuit board, and performs screen printing on the second electrode pattern, and which performs positioning between the first electrode pattern corresponding mask pattern of the mask member and the first electrode pattern of the circuit board, and performs screen printing on the first electrode pattern.
