The utility model relates to the field of semiconductor testing, and particularly discloses an adapter plate and equipment suitable for chip CP testing. The adapter plate comprises a plate body, one side of the plate body is a gas distribution face, the other side of the plate body is an adsorption face, and the gas distribution face and the adsorption face are both planes. A gas distribution groove is formed in the gas distribution surface, adsorption holes are distributed in the bottom of the gas distribution groove, and the adsorption holes penetrate through the plate body and are communicated with the adsorption surface. The chip is clamped and transferred by the adapter plate in a direct negative pressure adsorption mode, so that the operation efficiency and the detection precision are effectively improved.

The present application relates to material storage technology field, specifically to a kind of storage bin and its installation method, the storage bin includes bin wall and stress release seat, bin wall is equipped with multiple and multiple bin wall annular arrangement, to enclose storage cavity, stress release seat is arranged between two adjacent bin walls, and stress release seat is equipped with stress release groove on one of bin wall, and the other is equipped with sliding connection part, sliding connection part can be relatively slidably arranged in stress release groove.The present application can enclose storage cavity of storage material by multiple bin wall annular arrangement, when storage bin is subjected to temperature change and generates temperature stress (i.e. thermal expansion and contraction effect), the relative sliding of sliding connection part in stress release groove can release the temperature stress of bin wall, avoid the deformation damage or structural strength weakening of entire storage bin due to excessive temperature stress, improve the anti-deformation capacity and structural strength of storage bin.
