At this time, when the X-ray device is detected, the target set unit 200 with the actual correction value of 0mil can be observed first, and if the target set unit 200 observes that the correction value is not 0mil, it can be determined that the accuracy of the X-ray device has a deviation first, so that the structure can conveniently and quickly determine whether the X-ray device has a deviation.
In one embodiment, as shown in fig. 1 to 3, two side surfaces of the substrate 100 are a first side surface 110 and a second side surface 120, the first target 210 is disposed on the first side surface 110, the second target 220 is disposed on the second side surface 120, the first side surface 110 is disposed with a left deviation region 111 and a right deviation region 112, a plurality of first targets 210 are disposed in the left deviation region 111 and the right deviation region 112, the second target 220 corresponding to the first target 210 in the left deviation region 111 is a left deviation target 221, the second target 220 corresponding to the first target 210 in the right deviation region 112 is a right deviation target 222, in the same target group unit 200, a deviation direction of the left deviation target 221 with respect to the first target 210 is a direction in which the left deviation region 111 approaches the right deviation region 112, and a deviation direction of the right deviation target 222 with respect to the first target 210 is a direction in which the right deviation region 112 approaches the left deviation region 111. In this case, the offset direction of the second target 220 of the target group unit 200 with the correction value of not 0mil in the left offset region 111 and the right offset region 112 is a determined direction, and it can be observed that the actual correction value is not 0mil, but the target group unit 200 with the first target 210 overlapped with the second target 220 is located in the left offset region 111 or the right offset region 112, so as to determine the offset direction of the X-ray apparatus, thereby facilitating the direct adjustment of the X-ray apparatus. Wherein the offset direction of the X-ray apparatus is opposite to the offset direction of the second target 220 relative to the first target 210 in the target set unit 200.
