Abstract
The utility model discloses a stamp hole structure of a circuit board, which comprises a circuit board body, wherein two rows of stamp holes used for separating two circuit board units are formed on the circuit board body, two gonglike zones needing removing after a finished product is made are formed on the left and the right edges between the two rows of stamp holes, the inner ends of the two gonglike zones are positioned at the end part between the rows of stamp holes, the two gonglike zones are nonintersecting, and dedusting holes are respectively formed at the inner ends of the two gonglike zones. The utility model provides the stamp hole structure with low cost and good quality, and is widely applied in electronic Industries.
Description
[technical field]
The utility model relates to a kind of circuit board, and what be specifically related to is the stamp hole structure of circuit board.
[background technology]
In design circuit plate process, designer generally designs several stamp holes at circuit board gong groove edge, separates from the circuit board of bulk from being about to single junior unit circuit board so that it has mounted the back.
Yet, in the circuit board manufacturing process, need gong to fall waste material and circuit board leftover bits and pieces of material in the gong groove.The big template powder that produces can be squeezed into and stop up the stamp hole on gong groove next door, will cause following defective: the first, the plate powder is hidden and is stayed, and has influenced the stamp hole drilling quality.The second, because plate powder Tibetan allowance is big and because of extruding becomes hard, simultaneously, the stamp hole design is generally smaller, so circuit board manufacturer is difficult to remove stamp hole inner panel powder by washing plate.Three, hiding the plate powder stay in stamp hole mounts also in the future circuit board to have buried quality hidden danger.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art and stamp hole structure that the circuit board of a kind of low cost, quality product matter is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of stamp hole structure of circuit board, it is characterized in that including the circuit board body, on the circuit board body, be provided with and be used for separately two row's stamp holes of two circuit board units, two the gong groove zones of left and right limit between described two row's stamp holes for after making finished product, needing gong to fall, in the end of inner end, described two gong grooves zone between two row's stamp holes, two gong groove zones are non-intersect, are respectively equipped with the dedusting hole in inner end, two gong groove zones.
The stamp hole structure of aforesaid a kind of circuit board, the number that it is characterized in that described each row's stamp hole is 4.
The stamp hole structure of aforesaid a kind of circuit board is characterized in that the diameter of described dedusting boring ratio stamp hole is big.
The stamp hole structure of aforesaid a kind of circuit board is characterized in that the width in described dedusting boring ratio gong groove zone is little.
The utility model compared with prior art has following advantage: the utility model increases the dedusting hole slightly littler than groove width newly.Can address the problem like this: in gong sheet metal forming process, owing to increased the dedusting hole slightly littler than groove width newly at the groove end, the plate powder that is squeezed at the groove end can be bored smoothly, so just is not easy to be squeezed in the stamp hole.
[description of drawings]
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of prior art.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
A kind of stamp hole structure of circuit board includes circuit board body 1, is provided with to be used for separately two row's stamp holes 2 of two circuit board units on circuit board body 1.Two the gong groove zones 4 of left and right limit between described two row's stamp holes 2 for after making finished product, needing gong to fall, dotted portion as shown in the figure.In the end of 4 inner ends, described two gong grooves zone between two row's stamp holes 2.Described two gong grooves zone 4 is non-intersect, and two gong groove zone 4 distances apart are approximately the distance of 2 of two adjacent stamp holes.
Be respectively equipped with dedusting hole 3 in 4 inner ends, two gong groove zones.In the present embodiment, the number of described each row's stamp hole 2 is 4.Described dedusting hole 3 is bigger than the diameter of stamp hole 2.Described dedusting hole 3 is littler than the width in gong groove zone 4.
Stamp hole 2 is to be used for separately circuit board body 1, and described dedusting hole 3 is positioned at 4 inner ends, gong groove zone, and the hole of dedusting simultaneously 3 is also in two ends of arranging between the stamp holes 2.Because the plate powder that gong groove zone 4 produces in gong cutter operation will bore smoothly by dedusting hole 4.The plate powder just can not be squeezed in the stamp hole 2 on next door so, add the further reinspection and the help in dedusting hole 3, the dust energy high efficiency in the stamp hole 2 is thoroughly removed cheaply, guaranteed the stamp hole drilling quality, simultaneously also for future circuit board mount quality assurance be provided.
