  • Publication number: 20100176084
    Abstract: Disclosed is a squeeze for a screen printer. The present invention provides a squeeze for a screen printer, which coats a printed circuit board with an adhesive paste while moving parallel over a metal mask on the printed circuit board, the printed circuit board being open through an opening of the metal mask, the squeeze including a solvent storage unit for storing solvents; and solvent discharging holes for discharging the solvents, stored in the solvent storage unit, to an adhesive paste. Accordingly, the squeeze for a screen printer of the present invention may be useful to prevent a dog ear phenomenon, namely that an adhesive paste layer is asymmetrically formed in an indented manner, by controlling a viscosity of an adhesive paste by discharging a solvent onto an adhesive paste layer that comes in contact with the squeeze when the adhesive paste layer is formed in the printed circuit board.

  • Publication number: 20100087067
    Abstract: A method for packaging a semiconductor is provided to allow uniform coating of a die attachment paste, shorten a B-staging time, and improve die pick-up characteristics and die attachment characteristics. This method includes preparing a die attachment paste with a viscosity of 1,500 to 100,000 cps; rotating a wafer and applying the die attachment paste to an upper surface of the wafer into a predetermined thickness; and B-staging the paste applied on the wafer. This method makes it possible to reduce costs by substituting for WBL (Wafer Backside Lamination) film, uniformly apply a die attachment paste to a wafer, freely control a thickness of applied die attachment paste by adjusting viscosity and dosage of discharged paste and a speed of a spin coater, and also shorten a process time by decreasing a B-staging time.
