Abstract: Methods of forming a semiconductor package. Implementations include providing a leadframe, coupling a semiconductor die or an electronic component to the leadframe, and encapsulating at least a portion of the semiconductor die or the electronic component using a mold compound leaving two or more leads of the leadframe exposed. The method may also include coating the two or more leads of the leadframe with an electrically conductive layer. The method may include fully electrically and physically singulating one or more tie bars between two or more leads of the leadframe, a lead of the two or more leads and a leadframe flag, or any combination thereof. The method may also include singulating the leadframe to form one or more semiconductor packages.

Abstract: A method of forming a plurality of semiconductor packages includes providing an array of unsingulated semiconductor packages that are at least partially encapsulated in an encapsulant. The array of unsingulated semiconductor packages may be coupled with a lead frame or a substrate. A first plurality of singulation lines are simultaneously etched in the encapsulant through slits in an etch mask using a plasma etching process and a fixture coupled with the array. A second plurality of parallel singulation lines may also be etched. The first and second pluralities of singulation lines may include substantially straight or arcuate lines. The second plurality of parallel singulation lines may be substantially perpendicular to the first plurality of parallel singulation lines and be formed using the plasma etching process, the fixture, and an etch mask. The formation of singulation lines in the array singulates the array into a plurality of singulated semiconductor packages.

Abstract: A method of forming a leadframe (10) provides blocking fulcrums (21,23) adjacent to the leads (12,13,14, and 15). During the process of encapsulating the leadframe (10), the blocking fulcrums (21,23) restrict encapsulating material from exiting the mold cavity and from attaching to the leads (12,13,14, and 15).

Abstract: A method of forming leads and providing a final test of a semiconductor package including an electronic circuit therein, the package having unformed leads. A forming and testing station is provided including a support for receiving the package, and dies movably positioned adjacent the support for contacting and forming the leads with test equipment connected to the dies. The semiconductor package is positioned on the support, and the leads of the package are contacted with the dies to connect the test equipment to the leads for testing the electronic circuitry in the package and to form the leads with this contacting step as the final manufacturing step.
