Photon counting detector and preparation method thereof

The invention discloses a photon counting detector and a preparation method thereof, and the preparation method of the photon counting detector comprises the steps: enabling an adapter plate to be disposed on a peelable support plate in an attached manner; a machining plate is arranged on the side, away from the strippable carrier plate, of the adapter plate; stripping the strippable carrier plate from the adapter plate to expose one side, far away from the processing plate, of the adapter plate; a photoelectric conversion plate is arranged on the side, away from the machining plate, of the adapter plate, so that the photon counting detector is obtained. Through the above mode, the rigidity of the strippable carrier plate can be utilized to prevent the pinboard from deforming in the preparation process of a processing plate, and the bending resistance of the pinboard is improved, so that the buckling deformation of the photon counting detector in the packaging process is prevented, the risk of pseudo solderin
