Abstract
A chip tester is mounted on a circuit board for testing validity of a chipset includes a base member that receives the chipset thereon and that has a plurality of testing contacts in electrical communication with the circuit board and, and a top cover that is mounted on the base member to confine the chipset therebetween and has a test opening for access to the chip set. When the chipset is confined between the top cover and the base member, electrical contacts of the chipset are in contact with the testing contacts in the base member.

A chip tester mounted on a circuit board for testing validity of a chipset, the chipset including a base plate, a die disposed on an upper surface of the base plate, a plurality of electrical contacts disposed on a lower surface of the base plate, and an enclosure enclosing the base plate and the die in such a manner that the electrical contacts protrude outwardly from the enclosure, the chip tester comprising:
- a base member for receiving the chipset thereon, and having a plurality of built-in testing contacts that are adapted to be in electrical communication with the circuit board and the electrical contacts of the chipset;
- and
- a top cover mounted on the base member, and having a test opening for access to the chipset.
A top cover unit for use in a chip tester which, in turn, is mounted on a circuit board for testing validity of a chipset and which includes a base member for receiving the chipset thereon, the chipset including a base plate, a die disposed on an upper surface of the base plate, a plurality of electrical contacts disposed on a lower surface of the base plate, and an enclosure enclosing the base plate and the die in such a manner that the electrical contacts protrude outwardly from the enclosure, the top cover being disposed on the base member in order to permit extension of a testing needle for directly testing validity of the chipset, the top cover unit comprising:
- a main body having a test opening for exposing the die of the chipset to an exterior thereof once the chipset is uncapped;
- and
- a coupling member coupling the main body to the base member so as to confine the chipset between the main body and the base member.
