Methods for modifying a vertical surface mount package
View Patent ↗A vertically mountable semiconductor device including a plurality of stub contacts extending perpendicularly from a bottom edge thereof. The stub contacts may be formed by trimming the leads of an existing vertical surface mount package. A complementary alignment device includes a receptacle for receiving the vertically mountable semiconductor device. The alignment device is attachable to a carrier substrate. Upon attachment of the alignment device to a carrier substrate and insertion of a vertically mountable semiconductor device into the receptacle, a contact element applies a downward force to the vertically mountable semiconductor device to establish and maintain an electrical connection between the vertically mountable semiconductor device and the carrier substrate.
1. A method for modifying an existing semiconductor device package to create a semiconductor device package mountable in nonparallel relation to a carrier and including a plurality of leads and a bottom peripheral edge, the method comprising:
trimming the leads on the existing semiconductor device package close to the bottom peripheral edge thereof and substantially parallel to the bottom peripheral edge to form a plurality of substantially non-deformed stub contacts, prior to assembly of the semiconductor device package with a carrier or other electronic device component.
2. The method of claim 1 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of less than about one millimeter past the bottom peripheral edge.
3. The method of claim 1 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of less than about one-half millimeter past the bottom peripheral edge.
4. The method of claim 1 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of about 10 mils or less past the bottom peripheral edge.
5. The method of claim 1 , wherein trimming comprises trimming leads of a semiconductor device package that includes leads extending only from the bottom peripheral edge thereof, in mutually parallel relation, and at least partially within or parallel to a plane in which a semiconductor device of the semiconductor device package is located.
6. The method of claim 5 , wherein trimming comprises trimming leads adjacent to a cover of a semiconductor device package, the cover forming the bottom peripheral edge from which the leads extend.
7. A method for modifying an existing semiconductor device package that is configured to be secured to a carrier in nonparallel relation thereto, comprising:
trimming leads that extend from a single edge of the existing semiconductor device package to form a plurality of substantially non-deformed stub contacts prior to assembly of the semiconductor device package with a carrier or other electronic device component.
8. The method of claim 7 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of less than about one millimeter past the single edge.
9. The method of claim 7 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of less than about one-half millimeter past the single edge.
10. The method of claim 7 , wherein trimming comprises cutting the leads so that the stub contacts extend a length of about 10 mils or less past the single edge.
11. The method of claim 7 , wherein trimming comprises trimming leads of a semiconductor device package that includes leads extending from a single edge thereof, in mutually parallel relation, and at least partially within or parallel to a plane in which a semiconductor device of the semiconductor device package is located.
12. The method of claim 11 , wherein trimming comprises trimming leads adjacent to a cover of a semiconductor device package that forms the single edge from which the leads extend.
