AI Technical Summary

Problems solved by technology

However, such an inspection procedure is time-consuming, and the inspection speed is very slow. In today's fast-paced production and manufacturing, too many actions and procedures will not be able to effectively increase the output, which does not meet the principle of efficiency in inspection.

Embodiment Construction

[0049] In order to fully understand the purpose, features and effects of the present invention, now through the following specific embodiments, and in conjunction with the accompanying drawings, the present invention is described in detail, as follows:

[0050] See first Figure 2a , is a schematic diagram of a hole position information detection device in an embodiment of the present invention. The hole position information detection device of the present invention includes: a first illumination light source group 111 , a second illumination light source group 112 , an image capture device 120 and a control host 130 .

[0051] The first illuminating light source group 111 is arranged in the area above the position to be inspected to provide illumination light to the position to be inspected; the second group of illuminating light sources 112 is arranged in the area below the position to be inspected to provide illumination light to the position to be inspected. Figure 2a In...

Abstract

The invention discloses a detection method and detection device for hole site information of a printed circuit board. When a through hole passing through the printed circuit board are combined by two holes having a preset depth and drilled in two sides of the printed circuit board respectively and the two holes are irradiated by a light source, image picking is performed at one side of the printed circuit, relative information such as hole site offset of the two holes can be calculated through acquisition of information such as the aperture distance in an image and is provided for subsequent determination of the quality of drill holes. Accordingly, the detection method and the detection device can shorten the detection time and the detection cost without turning over the printed circuit board and arranging image picking devices on the two sides of the printed circuit board.

Description

technical field [0001] The invention relates to a detection method and detection equipment, in particular to a detection method and detection equipment for hole position information of a printed circuit board. Background technique [0002] Printed circuit boards are already one of the indispensable components of electronic, computer and communication products. Printed circuit boards have gradually developed into a technology that uses a large number of through holes, blind holes (blind holes or vias), and buried holes (buried holes). Blind vias and buried vias are used to connect the internal wiring boards with the surface wiring, without penetrating the entire board and wasting the layout space of other layers of wiring boards, thereby reducing the size of the printed circuit board. [0003] Even with the use of blind vias and buried vias, through-hole drilling technology is still an indispensable part in the manufacturing process of printed circuit boards for the electric...
