ABSTRACT:
Positioning marks are formed on both sides of each printing block on a tape carrier for TAB. A long-sized circuit board is transported by a roll-to-roll system in screen printing. When an optical sensor detects a positioning mark, transportation of the long-sized circuit board is stopped. Thereafter, the screen printing of a solder resist is performed to the printing block of the long-sized circuit board by a screen printing device.
