  • Dummy pad, a printed circuit board including the same, and a liquid crystal display including the same
    Patent number: 6266120
    Abstract: A dummy pad of a printed circuit board for display, delivering reference voltage, ground voltage or common voltage is divided into two portions and has a connection. The connection connects the two portions and is smaller than the two portions. The dummy pad of the printed circuit board is wider than a dummy pad of a soldering pad portion of a tape auto bonding-integrated circuit. Because the amount of the printed solder on the dummy pad of the printed circuit board is easily controlled, the heights of the solder drops is easily made to be equal, a soldering having a uniform adhesive strength is obtained. Furthermore, when the amount of the printed solder is different because the printed solder on one portion flows onto the other portion through the connection, the defects due to excessive solder and insufficient solder are reduced.
