Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, and in particular to a PCB board for monitoring hole quality. Background Technology

[0002] PCB boards are an indispensable and important component in modern electronic devices. They are boards that form electrical connections between electronic components by patterning conductive copper foil on the surface of insulating material. The main function of PCB boards is to realize electrical connections between electronic components through these copper foil lines and to support and fix the components on the board.

[0003] With the rapid development of 5G, PCB boards are also moving towards higher speeds and higher frequencies. The high quality requirements for PCB boards are becoming increasingly important. In order to ensure that the quality of PCB boards meets customer requirements, quality monitoring of PCB boards is particularly important during the production process. The comprehensiveness and rationality of the monitoring directly affect the production quality and cost. As a common hole for electrical conduction between PCB layers, the quality of the metallized holes directly affects the quality of the PCB boards delivered to customers. Currently, slicing holes are usually designed on the edge of the board to inspect whether the hole diameter, the thickness of the copper in the hole, and the wall quality of the hole meet customer requirements.

[0004] In existing technologies, small array holes are often designed at the four corners of the PCB board as slicing holes, and only one or two hole diameters are designed. However, designing one or two slicing holes is insufficient to monitor the quality of the metallized holes on the entire board. In particular, high-end PCB boards require monitoring the quality of metallized holes of multiple diameters. If it is necessary to detect the quality of metallized holes of other diameters during the inspection process, holes can only be drilled in the functional area of ​​the PCB board as slicing holes for monitoring, which leads to the scrapping of PCB sub-boards in the functional area, resulting in increased production costs and reduced delivery quantity. Utility Model Content

[0009] In one of the embodiments, the slicing area is provided with two slicing holes.

[0010] In one of the embodiments, the slicing holes are arranged in order from large to small or from small to large on the slicing area.

[0011] In one of the embodiments, the centers of the slicing holes are arranged on the same straight line.

[0012] In one of the embodiments, the minimum aperture of the slicing hole is 0.1mm.

[0013] In one of the embodiments, the maximum aperture of the slicing hole is 6.5mm.

[0014] In one of the embodiments, the interval distance of the slicing holes is less than or equal to 0.3mm.

[0015] In one of the embodiments, the PCB sub-boards are evenly distributed in the functional area.

[0016] In one of the embodiments, the edge of the slicing area is provided with a mark line.

[0017] Compared with the prior art, the utility model has at least the following advantages:

[0018] The PCB plate for monitoring hole quality of the utility model discloses a slicing area is arranged on the PCB frame, and the slicing of the PCB frame will not affect the function of the PCB plate, and a plurality of slicing holes with different apertures are arranged on the slicing area, so that when the quality of the PCB plate needs to be monitored, the slicing area can be cut from the PCB plate, and the aperture size, hole copper thickness and hole wall quality of each slicing hole in the slicing area are detected and recorded, and since the slicing holes in the slicing area cover the aperture size of all the metallized holes on the PCB plate, the slicing holes in the slicing area can monitor the quality of the metallized holes of the whole PCB plate, and the setting overcomes the defects that only one or two kinds of slicing holes with apertures are insufficient to monitor the quality of the metallized holes of the whole PCB plate, avoids the function of the functional area in the PCB plate from being lost due to the punching of the functional area when the quality of the metallized holes with other apertures needs to be detected, thereby reducing the production cost and improving the delivery quantity. BRIEF DESCRIPTION OF DRAWINGS

[0019] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the drawings needed to be used in the embodiments will be briefly introduced.

[0020] Figure 1 It is a structural schematic view of the PCB plate for monitoring hole quality in one embodiment of the utility model.

[0021] ILLUSTRATIONS: 10, PCB plate; 100, functional area; 200, PCB plate frame; 110, PCB sub-plate; 210, slicing area; 211, slicing hole; 220, long frame; 230, short frame; 212, identification line; DETAILED DESCRIPTION

[0022] In order to facilitate understanding of the utility model, the utility model will be described more comprehensively below with reference to relevant drawings.

[0023] Please refer to Figure 1 A kind of PCB plate 10 for monitoring hole quality, comprising: PCB plate 10 body, PCB plate 10 body includes functional area 100 and PCB plate frame 200, PCB plate frame 200 is arranged around functional area 100, multiple PCB sub-plates 110 are arranged in functional area 100, slicing area 210 is arranged on PCB plate frame 200, slicing area 210 is provided with multiple slicing holes 211 of different aperture, each slicing hole 211 penetrates PCB plate 10 body.

[0024] It should be noted that, by being provided with slicing area 210 on PCB plate frame 200, slicing PCB plate frame 200 will not cause the function of PCB plate 10 to be affected, and then by being provided with multiple slicing holes 211 of different aperture on slicing area 210, when PCB plate 10 needs to be monitored, slicing area 210 can be cut from PCB plate 10, and the aperture size, hole copper thickness and hole wall quality of each slicing hole 211 in slicing area 210 are detected and data are recorded, since slicing holes 211 in slicing area 210 cover the aperture size of all metallized holes on PCB plate 10, slicing holes 211 in slicing area 210 can monitor the quality of metallized holes of entire PCB plate 10, so setting, overcome the defect that only one to two aperture slicing holes 211 in prior art are insufficient to monitor the quality of metallized holes of entire PCB plate 10, avoid the function area 100 in PCB plate 10 is perforated when the quality of other aperture metallized holes needs to be detected, so that PCB sub-plate 110 loses function, thereby reduce production cost, improve delivery quantity.

[0025] Please refer to again Figure 1In an embodiment, the PCB plate frame 200 includes a long frame 220 and a short frame 230, and the slicing area 210 is arranged in the middle of the long frame 220. Since the slicing hole 211 is arranged on the short frame 230, a target hole needs to be designed, which increases the process flow and reduces the production efficiency. Arranging the slicing area 210 in the middle of the long frame 220 will not increase the process flow, and it is more conducive to the structural stability of the PCB plate 10.

[0026] Please refer again to Figure 1 In an embodiment, each slicing hole 211 is arranged in order from large to small or from small to large on the slicing area 210. Such an arrangement can make the data recording more orderly and clear when the slicing holes 211 are detected in order, avoiding interference with the process of manually monitoring the quality of the PCB plate 10.

[0027] Please refer again to Figure 1 In an embodiment, two slicing areas 210 are arranged. Such an arrangement improves the utilization rate of the PCB plate 10. When cutting the slicing area 210, one slicing area 210 may be scrapped due to human error, and the other slicing area 210 can be used as a backup, thereby further reducing production costs.

[0028] Please refer again to Figure 1 In an embodiment, the centers of the slicing holes 211 are arranged on the same straight line. Such an arrangement further facilitates manual monitoring of the slicing holes 211.

[0029] Please refer again to Figure 1 In an embodiment, the minimum aperture of the slicing hole 211 is 0.1 mm, and the maximum aperture of the slicing hole 211 is 6.5 mm, covering all the metallized holes on the PCB plate 10, so that the quality of all the metallized holes on the PCB plate 10 can be monitored at the same time, improving the monitoring effect of the metallized holes of the PCB plate 10.

[0030] Please refer again to Figure 1 In an embodiment, the spacing distance between the slicing holes 211 is less than or equal to 0.3 mm. In this way, one slicing area 210 can contain more slicing holes 211. When the spacing distance between the slicing holes 211 is greater than 0.3 mm, the slicing area 210 cannot cover all the slicing holes 211 on the PCB plate 10, so the area of the slicing area 210 needs to be expanded, which affects the structural stability of the PCB plate 10.

[0031] Please refer again to Figure 1 In an embodiment, each PCB sub-plate 110 is uniformly distributed in the functional area 100, which can improve the overall stability of the PCB plate 10.

[0032] Please refer againFigure 1 In an embodiment, the edge of the slicing area 210 is provided with a marking line 212, which improves the accuracy of manual cutting of the slicing area 210.

[0033] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
