Abstract: A detection apparatus and an anti-bending device thereof are provided. The detection apparatus includes a probe card circuit board, at least one probe, and the anti-bending device. The probe card circuit board has a first board surface and a second board surface on opposite sides thereof The at least one probe is mounted on the first board surface. The anti-bending device includes an anti-bending frame, at least one sensor, a processing circuit, and a transmission part. The anti-bending frame is mounted on the second board surface of the probe card circuit board, and the at least one sensor is disposed on the anti-bending frame or the probe card circuit board. The processing circuit is disposed inside the anti-bending frame. The transmission part is mounted on the anti-bending frame, and is electrically coupled to the processing circuit.
