Problems solved by technology

[0004] The first method: the test PCB board of each IP is made separately, the advantages are convenient, fast and clean; the disadvantage is that the cost of a single area is too expensive
[0005] The second way: multiple types of seamless splicing panels, the advantage is to save engineering costs, the disadvantage is that there will be jigsaw costs, and the cutting of the produced panels is time-consuming and laborious, taking up too much manpower, material resources and resources

Embodiment 1

[0025] The present invention will be described in more detail below in conjunction with the accompanying drawings, wherein a preferred embodiment 1 of the present invention is indicated. It should be understood that those skilled in the art can modify the present invention described here and still achieve the beneficial effects of the present invention.

[0026] Such as figure 1 As shown, several printed circuit boards are provided, and the several printed circuit boards are spliced. Specifically, take the splicing of four single PCB boards as an example. It is worth mentioning that the present invention does not specifically limit the specific number, size and shape of the PCB boards to be spliced, and an appropriate number of PCB boards can be selected according to specific needs. figure 1 The splicing method of four single PCB boards is shown in , the four PCB boards are PCB-1, PCB-2, PCB-3 and PCB-4 respectively, and the four boards have the same shape, wherein each singl...

Embodiment 2

[0031] figure 2 It shows an actual PCB splicing plan, taking the splicing of 10 PCB boards as an example, including PCB-20, PCB-21, PCB-22, PCB-23, PCB-24, PCB-25, PCB-26, PCB- 27. PCB-28 and PCB-29, among which 10 PCB boards are different in shape and size, PCB-20 is the single board with the largest area, its short side is spliced ​​with one side of PCB-21, and two splicing points are set, The other long side of PCB-20 is spliced ​​with PCB-22, PCB-24, and PCB-26. Due to the long side, the number of connected boards is large, and the corresponding splicing points are also increased. As an example, PCB-20 A total of 5 splicing points are set on the long side, and the splicing points are separated by holes. The distance between each splicing point can be the same or different, and it can be adjusted according to actual needs. As an example, the pitch of the splicing points is 0.5cm˜5cm. It is worth mentioning that, in order to facilitate the operation during the actual divi...

Abstract

The invention provides a jointing method for printed circuit boards, and the method comprises the following steps: providing a plurality of printed circuit boards, and jointing the plurality of printed circuit boards, wherein a side of each single printed circuit board is provided with a plurality of jointing points, and the jointing points are separated from each other through via holes. According to the invention, the method can avoid a V-CUT flow and cost, greatly reduces the engineering cost and jointing cost, and enables manufacturing cost of a single-area PCB to be greatly reduced. Meanwhile, the method facilitates the segmentation of a PCB, improves the segmentation efficiency of the PCB, greatly saves the manpower cost, avoid dedicated board-cutting equipment, and saves time, labor and equipment resources.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a method for imposing printed circuit boards. Background technique [0002] At present, as more and more IPs need to be tested, the test volume is also increasing, and the types and quantities of test boards corresponding to the needs are also increasing. Moreover, the test IP of the same type is also constantly being updated, and the types of corresponding test board printed circuit boards (Printed Circuit Board, PCB) are also being constantly updated. It is difficult to avoid updating and producing multiple versions of the PCB test board of each IP in different versions. However, if each type of PCB test board is produced separately when the quantity is not very large, the engineering cost will be several times higher than the cost of the PCB board itself; For additional splicing costs, a large amount of manpower and equipment resources must be arranged for the spliced...
