PCB via hole processing quality detection device

The utility model relates to the field of circuit board processing, in particular to a PCB via hole processing quality detection device which comprises a working platform, a through hole is formed inthe middle of the working platform, a support is arranged below the through hole, an X-ray emitter is arranged in the support, a protective cover is arranged above the working platform, a gap is formed between the protective cover and the working platform, and a PCB can move in the gap. An X-ray receiver is installed at the position, right opposite to the X-ray emitter, in the protective cover, acomputer is installed on the protective cover, the X-ray receiver is electrically connected with the computer, the X-ray receiver converts received X-rays into images visible to naked eyes and displays the images on a display screen of the computer in real time, and whether through hole machining is qualified or not is judged through the computer. The PCB via hole quality detection device is universal for detecting the qua
