Embodiment Construction

[0021] The embodiment of the present invention provides a kind of fixing plate of PCB board, such as figure 2 As shown, including the base plate, also includes the relief slot 1;

[0022] There are multiple relief grooves 1, which are respectively arranged at multiple relief positions of the substrate;

[0023] The step-off groove 1 is a groove that matches the appearance of the electrical components on the PCB that need to make way, and is used to accommodate the electrical components that need to make way on the PCB;

[0024] The bottom of the relief groove 1 is provided with a through hole 2 , and the cross-sectional area of ​​the through hole 2 is smaller than that of the relief groove 1 .

[0025] The place where the substrate needs to make way, that is, the A region shown in the figure, and the make way groove 1 is arranged in the A region.

[0026] Preferably, as a possible implementation manner, the depth of the relief groove 1 is equal to the distance that the elec...

Abstract

The invention discloses a fixing board for a PCB (Printed Circuit Board) and a machining method thereof. The machining method comprises the following steps: performing adhesive reducing treatment at a step-aside position on a substrate to thin the step-aside position in order to form a step-aside groove; and forming a through hole in the bottom of the step-aside groove, wherein the cross sectional area of the through hole is smaller than that of the step-aside groove. The problem of bulging deformation caused by thickness unevenness during machining of the fixing board for the PCB is solved; and meanwhile, the appearance effect of the fixing board stuck with a surface film on the outside is not influenced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a fixing plate of a PCB board and a processing method thereof. Background technique [0002] The fixing plate of the PCB board is used to accommodate and fix the PCB board, usually an injection molded part. In the design process of injection molding products, the material thickness is generally required to be uniform, that is, a certain thickness must be maintained everywhere, so that a good appearance surface can be guaranteed during the production heating process, that is, no deformation such as bulges will occur. [0003] In the development process of the fixed board of the PCB board, it is often encountered that due to the continuous updating of the components on the PCB board and the increase in the height and size of the components, the space for the fixed board is insufficient. At present, the following two methods are usually adopted solve: [0004] One is to use th...
