Abstract
The utility model relates to an anti-warping rigid printed circuit board. The excess copper ratio of the body part of a printed circuit board is basically equal to the excess copper ratio in each layer of waste boards because the area ratio of auxiliary graphs on the waste board is equal to that of the gaps which are mutually separated among the auxiliary graphs, and the area ratio of main graphs on the body part of the printed circuit board is equal to that of the gaps which are mutually separated among the auxiliary graphs; and when the temperature and the humidity are changed, the stretch of the body part of the printed circuit board and the stretch of the waste board can be basically the same, so that the warping and distortion of the printed circuit board can be greatly lowered.
Description
Technical field
The utility model relates to printed substrate and makes field, especially a kind of anti-warping rigidity printed substrate.
Background technology
In recent years, because semiconductor technology is fast-developing, the packing density of printed wiring board constantly develops to the High Level direction; Along with densification is installed; At the installation procedure of printed wiring board, because the crooked or distortion that printed wiring board produces has seriously influenced the qualification rate of installing.
So, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, and a kind of anti-warping rigidity printed substrate is provided.
For realizing above-mentioned utility model purpose, the anti-warping rigidity printed substrate of the utility model can adopt following technical scheme:
A kind of anti-warping rigidity printed substrate comprises the discarded plate of printed wiring board main part and non-printed wiring plate portion, between the auxiliary pattern area on the said discarded plate and the auxiliary pattern apart from one another by the ratio of slit area equate; Between main graphic area on the printed wiring main part and the auxiliary pattern apart from one another by the ratio of slit area equate.
Compare with background technology, the utility model through between the auxiliary pattern area on the discarded plate and the auxiliary pattern apart from one another by the ratio of slit area equate; Between main graphic area on the printed wiring main part and the auxiliary pattern apart from one another by the ratio of slit area equate; The residual copper rate of each layer is equal basically on printed wiring board main part and the discarded plate like this; When humiture changes; The flexible of printed wiring board main part and discarded plate can be basic identical, then can reduce warpage, the distortion of printed wiring board significantly.
Description of drawings
Fig. 1 is the structural representation of the anti-warping rigidity printed substrate of the utility model.
Fig. 2 is the enlarged diagram of discarded plate among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment; Further illustrate the utility model; Should understand these execution modes only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
See also shown in Figure 1; The utility model discloses a kind of anti-warping rigidity printed substrate 1; Between the discarded plate 3 that comprises printed wiring board main part 2 and non-printed wiring plate portion, auxiliary pattern 31 areas on the said discarded plate 3 and auxiliary pattern 31 apart from one another by the ratio of slit area 32 equate; Between main graphic on the printed wiring main part (not shown) area and the auxiliary pattern 31 apart from one another by the ratio of slit area 32 equate; The residual copper rate of each layer is equal basically on printed wiring board main part 2 and the discarded plate 3 like this; When humiture changes; The flexible of printed wiring board main part 2 and discarded plate 3 can be basic identical, then can reduce warpage, the distortion of printed wiring board 1 significantly.Main graphic on the printed wiring board main part 2 is two-layer above figure.
Claims (2)
1. anti-warping rigidity printed substrate is characterized in that: comprise the discarded plate of printed wiring board main part and non-printed wiring plate portion, between the auxiliary pattern area on the said discarded plate and the auxiliary pattern apart from one another by the ratio of slit area equate; Between main graphic area on the printed wiring main part and the auxiliary pattern apart from one another by the ratio of slit area equate.
2. anti-warping rigidity printed substrate as claimed in claim 1 is characterized in that: the main graphic on the printed wiring board main part is two-layer above figure.
