  • Method for screen printing solder paste onto a substrate with device premounted thereon
    Patent number: 4784310
    Abstract: A printing screen for screen printing fabrication substances such as solder paste has an aperture formed therein so that the screen may be placed on a substrate surface with a pre-mounted device extending through the aperture. A metal cap is bonded to the screen over the pre-mounted device to protect the device against damage during a subsequent screen printing operation. Different elements may, therefore, be bonded to a substrate in completely independent steps without the need for fluxing operations in later bonding operations.
    Type: Grant
    Filed: November 28, 1986
    Date of Patent: November 15, 1988
    Assignee: General Motors Corporation
