Abstract
Disclosed in the utility model is a measuring instrument for detecting an internal circuit of a PCB board. The measuring instrument comprises a detection platform for placing a to-be-detected PCB board and a computer device for detecting a 2D image. An X-ray tube and an image generating device are respectively arranged at two sides of the PCB board; the image generating device that is connected with the computer device is used for carrying out X-ray shooting on the PCB board at the detection platform to generate an X-ray image of the internal circuit of the PCB board. Because the X-ray device is used and is combined with the existing 2D detection measuring instrument, a traditional expanding amount mode is changed, a precision error of a drilling target drone itself can be overcome, and an expanding change of the PCB board is avoided. Therefore, a coordinate deformation situation of an internal graph of the PCB board can be precisely detected; a CNC drilling program and the internal graph of the PCB board are matched with each other well; a degree of alignment of a via hole and an inner-layer welding plate is improved; and a risk of discarding of a PCB board due to hole drilling deviation can be reduced.
