<p><P>PROBLEM TO BE SOLVED: To provide a more practical screen printing line and printing method. <P>SOLUTION: The screen printing line has: two printers 10 arranged side by side; four mounters 14 arranged on the downstream side of them: shuttle conveyors 12 respectively arranged between the adjacent printers 10 and on the downstream side of the downstream printer 10. The printers 10 each have a front and rear conveyers 22 and 24, and solders are printed on circuit boards in main conveyers 50 of the front conveyers 22. An upstream movable conveyer 152 moves to the positions communicating with the conveyers 22 and 24 of the adjacent printer 10, while a downstream movable conveyer 152 moves to the positions communicating with the conveyers 22 and 24 of the printer 10 and communicating with conveyers 240 of the mounters 14, so as to supply and receive the circuit boards. Attachment of different masks on the two printers 10 enables a parallel solder printing on both front and back sides of circuit board of the same type, or attachment of the same masks enables a parallel solder printing on front surfaces of the circuit boards. Three or four printers 10 may also be used. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
