Abstract: A test apparatus for testing electronic device comprises a lower base, an upper base and a pressing force generating module disposed between the upper and lower bases. The lower base having a chip socket for receiving a plurality of probes, and a test socket plate having a first guiding device, each of the probes has a spring force stored therein. The upper base having a second guiding device coupled to the first guiding device. When an electronic device is placed in the chip socket, and the upper base is slidably moved with respect to the lower base by the cooperative actions between the first and second guiding devices, so that the pressing force generating module is in alignment with the electronic device for applying a pressing force on the electronic device, and the pressing force being greater than the sum of the spring forces generated by the plurality of probes.

Abstract: A rotating buffer station for a chip mainly comprises an upper cover plate, a rotatable plate, a movable jaw member and a lower base. The upper cover plate is arranged on the lower base and formed with a guide slot. The rotatable plate is located between the lower base and the upper cover plate and formed with a cam slot. The rotatable plate is pivotally coupled to the lower base. The movable jaw member is slidably engaged with the cam slot and the guide slot. When the rotatable plate is rotated, the cam slot forces the movable jaw member to move radially along the guide slot so as to form a chip socket. Accordingly, with rotation of the rotatable plate, the cam slot forces the movable jaw member to move radially along the guide slot so that the chip socket can be resized to hold various differently-sized chips.
