Abstract
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, an abutting member, and an airtight member. The cover is disposed on the circuit board to jointly define an accommodating space accommodating the abutting member and the electrically connecting units. The airtight member is arranged between the cover and the circuit board to seal the accommodating space. The cover has at least one exhaust hole. When an air suction apparatus exhausts air in the accommodating space through the at least one exhaust hole, the cover is abutted against the airtight member, and the abutting member is abutted against the chips to connect each of the electrically connecting units and the corresponding chip.
