Samsung patents a fixture that holds chips steady during testing
This filing describes a mechanical fixture used to test semiconductor chips. It uses a base plate, elastic cylinders, and locking stops to hold a chip in place between a top plate and a substrate cover.
In the filing’s own words
A semiconductor test apparatus includes a base plate, side supporters provided as three or more on a lower surface of the base plate, an elastic cylinder and a side stopper provided on a lower surface of each of the side supporters, a center stopper provided laterally apart from the side supporters on the lower surface of the base plate, a stopper foot provided at one end of the center stopper, a foot supporter provided at one end of the stopper foot, a top plate disposed under the base plate to contact the elastic cylinder and the side stopper, the top plate including a center hole in a center portion thereof, and a substrate cover provided under the top plate, wherein the center stopper and the side stopper are selectively locked.
What exactly they claim (claim 1)
1. A semiconductor test apparatus comprising: a base plate; a plurality of side supporters on a lower surface of the base plate; an elastic cylinder and a side stopper on a lower surface of each of the plurality of side supporters; a center stopper laterally spaced apart from the plurality of side supporters on the lower surface of the base plate; a stopper foot at one end of the center stopper; a foot supporter at one end of the stopper foot; a top plate under the base plate and configured to contact the elastic cylinder and the side stopper, wherein the top plate comprises a center hole in a center portion thereof; and a substrate cover under the top plate, wherein the center stopper and the side stopper are configured to be selectively locked.
