Detailed Description

In the following, the embodiments of the present invention will be described in detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, back \8230;) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

It will also be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Furthermore, the descriptions in the present application related to "first", "second", etc. are for descriptive purposes only and are not to be construed as indicating or implying relative importance or to imply that the number of technical features indicated are implicitly being indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory to each other or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The utility model provides a PCB makeup, refer to fig. 1-4, this PCB makeup includes that a plurality of intervals set up and the PCB veneer 1 that connects gradually, has seted up recess 2 between the two adjacent PCB veneers, and the tank bottom of recess is constructed has a plurality of through-holes 3.

In this embodiment, need interconnect between PCB veneer 1, before preparation PCB veneer 1, can carry out layout design on the computer, with PCB veneer 1 with the most saved structure interconnect, then unified production of rethread producer comes out carries out the makeup, the makeup is for the convenience of producer batch production PCB veneer 1, on the other hand then is that it is more convenient with the customer's use mode behind the 1 makeup of PCB veneer, so can be linked together between a plurality of PCB veneers 1, junction between every PCB veneer 1 is equipped with through-hole or recess 2, so just can carry out the branch board fast, this scheme is with the through-hole with use together, carry out 1 makeup of PCB veneer, the through-hole of this scheme and the arrangement mode of recess 2 can be multiple, can set up the through-hole on recess 2, then do not need special branch board tool.

In some embodiments, referring to fig. 2-4, both sides of the pcb single board are provided with grooves 2, and the two grooves 2 correspond to each other.

In this embodiment, PCB veneer 1's both sides all are equipped with recess 2, so PCB veneer 1's junction can only open one side recess 2 just because through-hole 3 sets up on recess 2, but for easily dividing the board, set up the two sides, concrete one side still two sides are set up recess 2 and are seen PCB veneer 1's thickness, if PCB veneer 1 only sets up the condition that the burr can appear in the one side, then can all set up recess 2 with PCB veneer 1's two-sided, if PCB veneer 1's thickness undersize, only need set up recess 2 in the one side then can, set up on recess 2 because of through-hole 3, the makeup junction stress point of this scheme is inhomogeneous, it is easier when can dividing the board.

In some embodiments, referring to fig. 2-4, the groove 2 is V-shaped in cross-section.

In this embodiment, the groove 2 provided in the PCB single board 1 may have various shapes, but in order to make the PCB single board 1 easily separated when splitting the board, the V-shaped groove 2 may make the stress point concentrate on the bottom of the groove 2 when splitting the board, wherein the small opening of the V-shaped groove faces to the other side direction of the PCB single board 1, and the large opening direction of the V-shaped groove 2 is opposite to the small opening direction.

In some embodiments, referring to fig. 2-4, the groove depth of the groove 2 is less than or equal to one third of the thickness of the PCB single board 1.

In this embodiment, recess 2 sets up in PCB veneer 1's junction purpose in order to let convenient fixed when need not taking apart between a plurality of PCB veneers 1, so the degree of depth that recess 2 seted up can make easily part between a plurality of PCB veneers 1 if too deeply, and if under the condition of recess 2 is all set up on both sides, so the degree of depth that recess 2 seted up needs to be less than the one-third of PCB veneer 1 thickness more easily between PCB veneer 1, like this if the junction thickness of a plurality of PCB veneers 1 also remains one-third for the body under the condition that recess 2 was all set up on both sides of PCB veneer 1.

In some embodiments, referring to fig. 1, the PCB board further includes a fixing member 4 disposed on a peripheral side of the PCB board 1 and connected thereto.

In this embodiment, the PCB makeup is a monoblock PCB board that has not been handled, when having designed PCB veneer 1 on the computer and specifically having distributed, then process the PCB makeup through the mill, set up through-hole 3 and recess 2 on the PCB makeup to separate into a plurality of PCB veneers 1, in order to fix these PCB veneers 1 that have handled, and do not receive unexpected factor and lead to separating in advance between the PCB veneer 1, so utilize mounting 4 to fix a plurality of PCB veneers 1.

In some embodiments, referring to fig. 2-4, the distance between two adjacent through holes 3 is the same.

In this embodiment, through-hole 3 is equipped with a plurality ofly and all evenly distributed on recess 2, and the junction of a plurality of PCB veneers 1 is more weak for other places this moment, is parted more easily, so after setting up a plurality of evenly distributed's through-hole 3 on recess 2, can make PCB veneer 1 divide the board more easily, still does not need special branch board tool to carry out the branch board operation simultaneously.

Various embodiments or examples and features of various embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

What just go up be the utility model discloses a part or preferred embodiment, no matter be characters or the drawing can not consequently restrict the utility model discloses the scope of protection, all with the utility model discloses a holistic thought down, utilize the equivalent structure transform that the contents of the description and the drawing do, or direct/indirect application all includes in other relevant technical field the utility model discloses the within range of protection.
