Patent ID: 7077170

Claim:
A method of forming leads of a packaged semiconductor device that includes a package having opposed first and second sides and first and second leads extending outwardly from the first and second sides of the package, respectively, the method comprising: adjusting separation between first and second bottom dies to receive the package of the packaged semiconductor device between the first and second bottom dies, the first and second bottom dies having respective top surfaces that include oblique portions; placing the package of the packaged semiconductor device between the first and second bottom dies with the first and second lead proximate the top surfaces of the first and second bottom dies, respectively; moving at least one of the first and second bottom dies and first and second top dies having respective bottom surfaces with oblique portions complementary to the top surfaces of the first and second bottom dies, respectively, toward each other; clamping the first and second leads between the top and bottom surfaces of the first top and bottom dies and between the second top and bottom dies, respectively, and urging the first top and bottom dies and the second top and bottom dies together, thereby forming the first and second leads, and, simultaneously, producing lateral forces through contact of the complementary top and bottom surfaces and the first and second leads, and, in response to the lateral forces, moving the first and second top dies laterally, relative to the first and second bottom dies, thereby changing separation between the first and second top dies.
