Abstract: The invention provides semiconductor device packages, leadframes, and methods for their manufacture, with improved characteristics for the formation of metallurgical joints. In a disclosed preferred embodiment of a semiconductor device leadframe according to the invention, a generally rectangular sheet metal body has a semiconductor device mounting site for receiving a semiconductor device. Leadfingers extend from the proximity of the device mounting site the outer edges of the leadframe. An anchor pad is included at each corner of the leadframe body, each anchor pad having a patterned surface. According disclosed aspects of the invention, the patterned surfaces of the anchor pads may include indented, embossed, or cut-out portions. According to other aspects of the invention, patterned anchor pad surfaces are plated with a low-melting point alloy and remain exposed at the corners of an encapsulated package.

Abstract: A carrier and package for plural semiconductor devices includes a member with device-conformal apertures therethrough. A first removable cover is attached to one side of the member to close one end of each aperture. After devices are inserted into the apertures with their first ends “up” and their second ends “down,” a second removable cover is attached to the other side of the member to close the other end of each aperture. After inverting the assembly, removal of the first cover presents the devices in the apertures with their second ends “up” and their first ends “down.

Abstract: A reel adapted to have chip carrier tape wound thereabout includes at least one flange and a plastic rail. The flange is made from a paper-based material. The plastic rail is attached an interior major surface of the paper flange. The plastic rail may extend along a radial direction of the flange and/or along a circumferential direction of the flange, for example. The plastic rail may be substantially straight and/or curved, for example. The plastic rail is preferably made from a static dissipative material. The plastic rail reduces or eliminates the generation of paper particles from the paper-based flange while reeling/unreeling chip carrier tape from the reel.
