Abstract
A method for making and using a test fixture (10) for testing a packaged semiconductor device (44). The test fixture (10) includes a nonconductive housing (11) and a contactor assembly (30). The contactor assembly (30) has a contactor lead (31) and is removable from the housing (11). The contactor assembly (30) is mounted to the housing (11) such that the contactor lead (31) becomes interdigitated between upper cantilever structures (20) and lower cantilever structures (21). The test fixture (10) is coupled to a tester (46) which is between a first tool set (41) and a second tool set (42) of a trim and form apparatus (40). The packaged semiconductor device (44) is placed in contact with the test fixture (10) and tested.
Claims20
An adjustable test fixture for mating with leadframe leads, comprising:
- an electrically nonconductive base, the electrically nonconductive base having at least one side wherein the at least one side has a recess extending into the electrically nonconductive base and terminating at a backwall;
- a plurality of guidemembers extending from the backwall;
- and
- a detachable contactor assembly, the detachable contactor assembly having a top side and a bottom side and a plurality of leads which mate with the plurality of guidemembers, each lead having a first end and a second end wherein the first end projects from the top side and the second end projects from the bottom side.
An adjustable test fixture, comprising:
- a base having a plurality of sides, wherein a first side of the plurality of sides has a recess having a mouth and a backwall;
- a first plurality of cantilever structures extending from the backwall of the recess in the first side of the plurality of sides, wherein the cantilever structures of the first plurality of cantilever structures are spaced apart from each other;
- a second plurality of cantilever structures extending from the backwall of the recess in the first side of the plurality of sides, and wherein the cantilever structures of the second plurality of cantilever structures are spaced apart from each other and each of the second plurality of cantilever structures is aligned with a corresponding cantilever structure of the first plurality of cantilever structures;
- and
- a first detachable contactor assembly for mating with the base, wherein the first detachable contactor assembly comprises a case having a top side, a bottom side, and at least one contactor lead having a first end extending from the top side and a second end projecting from the bottom side.
