TAB (1 Metal Circuit with Adhesive)

The significant feature of TAB is flying leads, which are hanging over holes in polyimide film. This can be realized because the film with adhesive is punched out before copper foil is laminated. Especially for TCP (Tape Carrier Package), IC chip can be attached on both top side and bottom due to the flying leads structure over through holes. TAB is suitable for digital equipment, mobiles, because the fine pitch substrate make them smaller and lighter.
