<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a tape carrier for TAB capable of carrying out screen printing of solder resist with high precision while suppressing an increase in the number of steps and waste of material. <P>SOLUTION: Positioning marks PM1 and PM2 are formed on both sides of each printing block 13 on the tape carrier 1 for TAB. In screen printing, a long-shaped circuit substrate 10 is transported by a roll-to-roll system. When an optical sensor detects the positioning mark PM1, the transport of the long-shaped circuit substrate 10 stops. Then, a screen printing device 100 carries out screen printing of solder resist on the printing blocks 13 of the long-shaped circuit substrate 10. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
