Abstract
The utility model relates to a back-off jointed board comprises a first jointed board (100) and a second jointed board (200), wherein the first jointed board (100) comprises a first effective part (101) and a first ineffective part (102), and the second jointed board (200) comprises a second effective part (201) and a second ineffective part (202). When the back-off jointed board is in use, one side of the first ineffective part (102) of the first jointed board (100) is overlapped with one side of the second ineffective part (202) of the second jointed board (200), and the overlapped part is a first effective part (300) and a second effective part (400) respectively. In the utility model, an L-shaped circuit board is processed to be the back-off jointed board which rotates at 180 degrees, effective parts of the two circuit boards mutually go deep into the ineffective parts of the other circuit board, so as to make full use of the whole ineffective parts and reduce the area of the ineffective parts, and the effective utilization ratio of the raw material is improved.
Description
Technical field
The utility model relates to a kind of back-off jigsaw, particularly relates to the back-off jigsaw that adopts in a kind of L type profile wiring board course of processing.
Background technology
Because electronic product is more and more littler now, it is more and more littler that this just makes that the size of printed substrate also requires, and the price of printed substrate is also more and more expensive, so in the making and use of printed substrate, in order to save cost, the polylith printed substrate can be stitched together.
The utility model content
At the problems referred to above, main purpose of the present utility model is to provide the back-off jigsaw that adopts in a kind of L type profile wiring board course of processing.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of back-off jigsaw, described back-off jigsaw comprises first jigsaw and second jigsaw, comprise first live part and the first invalid part on described first jigsaw, comprise second live part and the second invalid part on described second jigsaw, it is characterized in that: with a side superimposed of the second invalid part of the side of the first invalid part on first jigsaw and second jigsaw, the part after the coincidence is respectively first live part and second live part in use.
Positive progressive effect of the present utility model is: the back-off jigsaw that the utility model provides has the following advantages: the utility model is made the wiring board of L type profile the back-off jigsaw of Rotate 180 ° in the course of processing, and make the live part of two wiring boards wherein go deep into the invalid part of another piece wiring board mutually, whole invalid part is made full use of, invalid part area is reduced, improve raw-material effective rate of utilization thereby arrive.
Description of drawings
Fig. 1 is the structural representation of first jigsaw of the present utility model.
Fig. 2 is the structural representation of second jigsaw of the present utility model.
Fig. 3 is the structural representation after first jigsaw of the present utility model and second jigsaw splice well.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Jigsaw among the figure of the present utility model is " L " type, as shown in Figure 1, Fig. 1 is the structural representation of first jigsaw of the present utility model, comprise first live part 101 and the first invalid part 102 on first jigsaw 100, Fig. 2 is the structural representation of second jigsaw of the present utility model, comprise second live part 201 and the second invalid part 202 on second jigsaw 200, Fig. 3 is the structural representation after first jigsaw of the present utility model and second jigsaw splice well, as shown in Figure 3, with a side superimposed of the second invalid part 202 of the side of the first invalid part 102 on first jigsaw 100 and second jigsaw 200, the part after the coincidence is respectively first live part 300 and second live part 400 in use.
The wiring board of L type profile is made the back-off jigsaw of Rotate 180 ° in the course of processing, and make the live part of two wiring boards wherein go deep into the invalid part of another piece wiring board mutually, whole invalid part is made full use of, invalid part area is reduced, improve raw-material effective rate of utilization thereby arrive.
In specific embodiment of the utility model, when the polylith jigsaw is arranged, can adopt similar method that jigsaw is stitched together.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
