Abstract
The utility model discloses a stainless steel stiffening plate of gum structure, nonrust steel sheet and glue film including laminating each other, the glue film includes outer lane glue film and inner circle glue film, and divides separating groove to keep apart through the round between outer lane glue film and the inner circle glue film, the outer lane glue film is still connected through being connected the glue film at the interval with the inner circle glue film, and outer lane glue film, inner circle glue film and connection glue film structure as an organic whole. The utility model discloses a through setting up branch separating groove at the glue film in order to keep apart inside and outside glue film to connect the integrated glue film of the interior outer joint of inside and outside glue film formation through connecting the glue film, the expansion stress of this kind of structure through dividing separating groove release inner circle glue film, thus effectively avoid the glue film to follow peeling off of nonrust steel sheet, guarantee the validity of stiffening plate.
Description
Technical field
The utility model relates to a kind of stainless steel stiffening plate of gum structure.
Background technology
Flexible PCB with its height reliability, excellent pliability, distribution density is high, lightweight, thickness is thin feature, and is widely used on a lot of product such as mobile phone, notebook computer, PDA, digital camera, LCM.Because flexible circuit board has flexibility, therefore need to carry out reinforcement to strengthen its mechanical performance for paster region or land.Conventional stainless steel reinforcing chip is made up of the conducting resinl on stainless steel substrates and its surface of fitting, and release liners need be pasted on conducting resinl surface before use, but because conducting resinl is different from the thermal coefficient of expansion of stainless steel substrates, when electronic component heating after reinforcement makes to occur during stiffening plate expanded by heating the undesirable condition that glue-line and stainless steel substrates depart from.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of stainless steel stiffening plate of gum structure, occurs to avoid stiffening plate thermal expansion the undesirable condition that glue-line and stainless steel substrates are peeled off.
For achieving the above object, the technical solution of the utility model is as follows:
A stainless steel stiffening plate for gum structure, comprises stainless steel substrates bonded to each other and glue-line;
Described glue-line comprises outer ring glue-line and inner ring glue-line, and encloses separation trough by one between described outer ring glue-line and inner ring glue-line and isolate;
Described outer ring glue-line and inner ring glue-line also interval connect by being connected glue-line, and described outer ring glue-line, inner ring glue-line and connection glue-line are structure as a whole.
Wherein, the width H1 of described outer ring glue-line is greater than the width H3 of described separation trough, i.e. H1 > H3.
Wherein, the width H1 of described outer ring glue-line is less than 1/2nd, i.e. H1 < H2/2 of described inner ring glue-line width H2.
Pass through technique scheme, the stainless steel stiffening plate of the gum structure that the utility model provides, it is by arranging separation trough to isolate inside and outside glue-line at glue-line, and connect by connecting glue-line the integrated glue-line that inside and outside glue-line forms inside and outside connection, this kind of structure discharges the swelling stress of inner ring glue-line by separation trough, thus effectively avoid glue-line from the stripping of stainless steel substrates, guarantee the validity of stiffening plate.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the stiffening plate plan structure schematic diagram disclosed in the utility model embodiment;
Fig. 2 be in Fig. 1 A-A to sectional structure schematic diagram;
Fig. 3 be in Fig. 1 B-B to sectional structure schematic diagram.
Numeral in figure:
11. outer ring glue-line 12. inner ring glue-line 13. separation troughs
14. connect glue-line 15. stainless steel substrates
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1-3, the stainless steel stiffening plate of the gum structure that the utility model provides, comprises stainless steel substrates 15 bonded to each other and glue-line; Glue-line comprises outer ring glue-line 11 and inner ring glue-line 12, and encloses separation trough 13 by one between outer ring glue-line 11 and inner ring glue-line 12 and isolate; Outer ring glue-line 11 and inner ring glue-line 12 also interval connect by being connected glue-line 14, and outer ring glue-line 11, inner ring glue-line 12 and connection glue-line 14 are structure as a whole.
Wherein, the width H1 of outer ring glue-line 11 is greater than the width H3 of separation trough 13, i.e. H1 > H3; The width H1 of outer ring glue-line 11 is less than 1/2nd of inner ring glue-line 12 width H2, i.e. H1 < H2/2.
The utility model arranges separation trough 13 to isolate inside and outside glue-line by die-cut mode at glue-line, and connect by connecting glue-line 14 the integrated glue-line that inside and outside glue-line forms inside and outside connection, this kind of structure discharges the swelling stress of inner ring glue-line 12 by separation trough 13, thus effectively avoid glue-line from the stripping of stainless steel substrates 15, guarantee the validity of stiffening plate.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
