Patent attributes
A testing apparatus includes a chip carrying device and a pressing device. The chip carrying device includes a circuit board and a plurality of electrically connecting units that are disposed on the circuit board and each can receive a chip. The pressing device includes a cover and an abutting member disposed between the cover and the electrically connecting units. The cover is disposed on the circuit board to jointly define an accommodating space that accommodates the abutting member and the electrically connecting units. The cover can be connected to an air suction apparatus for expelling air in the accommodating space. When the air suction apparatus performs a suction operation to expel the air in the accommodating space, the abutting member is abutted against the electrically connecting units and the chips so as to connect each of the electrically connecting units and the corresponding chip.
