Description
Technical field
The utility model relates to print circuit plates making technical fields, quick more particularly to a kind of printed circuit-board assembly
Scoreboard structure.
Background technique
PCBA (Printed Circuit Board Assembly, printed circuit-board assembly) is generated during scoreboard
Mechanical stress is easy to damage multi-layer ceramic capacitance, so as to cause part function failure.Simultaneously jigsaw design in because too much
V-CUT slot causes production efficiency low.Therefore, it is necessary to a kind of new scoreboard structure be designed, to solve the above problems.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of can guarantee and makes pottery without scoreboard mechanical stress to multilayer
Porcelain capacitor impacts, and improves the quick scoreboard structure of printed circuit-board assembly of scoreboard efficiency.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of quick scoreboard structure of printed circuit-board assembly, including multiple veneer printed circuit boards being connected in one, institute
The two sides edges of boards for stating veneer printed circuit board are equipped with gong slot, and the gong slot extends the entire edges of boards of the veneer printed circuit board
Length.
Further, edge grinding is equipped between two gong slots that the adjacent veneer printed circuit board is closer.
Further, the edge grinding width is 3mm.
Further, the width of the gong slot is 1mm.
Further, the gong flute profile forming V-shape slot.
Further, location hole is equipped on the outside of the gong slot of the veneer printed circuit board at both ends.
The utility model has the beneficial effects that
Gong slot is set in the two sides edges of boards of veneer printed circuit board, and gong slot extends the entire plate of veneer printed circuit board
Edge lengths then reduce the quantity of V-CUT slot, improve scoreboard efficiency, while causing to multi-layer ceramic capacitance without scoreboard mechanical stress
It influences, edge grinding is equipped between the gong slot of two adjacent veneer printed circuit boards, edge grinding plays the role of keeping off tin, crosses wave-soldering process
When molten tin bath in tin will not swarm come.
Detailed description of the invention
Fig. 1 is the quick scoreboard structure of the utility model printed circuit-board assembly；
In figure, 1-veneer printed circuit board, 2-gong slots, 3-edge grindings, 4-location holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
Such as Fig. 1, the utility model provides a kind of quick scoreboard structure of printed circuit-board assembly, including multiple is connected in one
Veneer printed circuit board 1, veneer printed circuit board 1 realize its electrical functionality.The two sides edges of boards of each veneer printed circuit board 1
Equipped with gong slot 2, gong slot 2 extends the entire edges of boards length of veneer printed circuit board 1.In the present embodiment, the width of gong slot 2 is
1mm.Preferably, gong slot 2 forms V-shaped groove, in order to scoreboard.Multiple veneer printed circuit boards 1 are connected, realize high efficiency
Production is arranged gong slot 2 in edges of boards, reduces the V-CUT slot number of edges of boards, makes scoreboard improved efficiency 85%, and can avoid board separator
Influence of the tool stress to multi-layer ceramic capacitance.
Edge grinding 3 is equipped between two gong slots 2 that two neighboring veneer printed circuit board 1 is closer, in the present embodiment,
The width of edge grinding 3 is 5mm.Pass through the design of edge grinding 3, it is ensured that the tin of molten tin bath, which will not swarm, in wave-soldering comes.Two 1mm gongs
Slot 2 adds 3mm edge grinding 3, so that having the space 5mm between two neighboring veneer printed circuit board 1, facilitates the life of high density product
Produce operation.
It is equipped with location hole 4 on the outside of the gong slot 2 of the veneer printed circuit board 1 at both ends, improves the essence of scoreboard and plug-in unit
Degree.
The quick scoreboard structure of the printed circuit-board assembly of the utility model reduces the quantity of V-CUT slot, improves scoreboard effect
Rate, while multi-layer ceramic capacitance is impacted without scoreboard mechanical stress, and edge grinding plays the role of keeping off tin, when crossing wave-soldering process
Tin in molten tin bath, which will not swarm, to be come.
Above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to preferred embodiment pair
The utility model is described in detail, it will be appreciated by those skilled in the art that can to the technical solution of the utility model into
Row, which is modified, or equivalent replacement is without departing from the objective and range of the technical program should all cover the power in the utility model
In sharp claimed range.
