Description
Technical field
The utility model belongs to high-density plate technical field, is specifically related to one and has intensive pad high-density plate.
Background technology
In some specific field, common rigidity PCB has been difficult to meet the product assembling requirement special to it, and flex circuit application is just obtaining with the three-dimensional flexibility of its excellence and applying more and more widely.Along with electronic product is to high density, miniaturization, high reliability future development, flexural high density plate can bend with it, fold, reduced volume, alleviate quality and the feature such as easy to assembly, is especially applicable to the requirement of current electronic product for light, thin, short, little feature.In PCB industry, flexural high density plate increases a very fast class printed board this year, and growth rate is fast, wide market.No matter be from consumer electronics product, or automotive field, communication, medical electronics, the device systems that even high-end airborne vehicle is installed all has a very wide range of applications.
In traditional handicraft, the required coverlay covered of flexural high density plate is first windowed according to certain figure and size by the means such as die-cut, and then fit with Copper Foil, but for intensive pad, coverlay is windowed under window, and spacing between window is little, cannot be completed by the mechanical punching of routine.
Therefore, need a kind of new technical scheme to solve the problem.
Utility model content
Utility model object: for above-mentioned prior art Problems existing and deficiency, the purpose of this utility model is to provide a kind of intensive pad high-density plate.
Technical scheme: the utility model discloses a kind of intensive pad high-density plate, comprise backing material plate, coverlay, ink layer and developing layer, described backing material plate is provided with part zone, described coverlay offers the district of windowing of exposing part zone, described district's area of windowing is greater than part zone, described ink layer is covered in district of windowing, described developing layer is covered on ink layer ink layer exposure imaging, special less for part zone, the comparatively intensive high-density plate of pad, some windows need not be offered, also avoid gap between window and window too small, affect the situations such as following process to occur.
As further optimization of the present utility model, ink layer described in the utility model is liquid photosensitive ink, and the full version printing of liquid photosensitive ink forms ink layer, and liquid photosensitive ink, after photo-curing, development, can etch, the process such as plating.
As further optimization of the present utility model, developing layer described in the utility model comprises film egative film.
Realize a kind of windowing method with intensive pad high-density plate of the present utility model, comprise the following steps:
Coverlay is fitted on backing material plate by 1;
The coverlay of 2 position, corresponding part zone offers window region, exposes whole part zone;
3 at part zone silk-screen liquid photosensitive ink;
4 adopt film egative film, and exposure imaging is carried out in liquid towards photosensitive-ink region, exposes part pad.
Beneficial effect: the utility model compared with prior art, have the following advantages: the utility model is by offering area the window district large compared with part zone in part zone, some small size windows need not be offered, equally, avoid spacing between window and window too small, be inconvenient to carry out follow-up work, the utility model adopts liquid photosensitive ink silk screen printing in window region, film egative film is adopted to develop, the utility model high-density plate structure is simple, windowing method is easy to operate, Be very effective, has good economic benefit.

1-backing material plate; 11--part zone; 2--coverlay; 3-district of windowing.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail; but illustrate that protection range of the present utility model is not limited to the concrete scope of the present embodiment simultaneously; based on the embodiment in the utility model; those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, in description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second ", " the 3rd " etc. only for describing object, and can not be interpreted as instruction or hint relative importance.
Embodiment:
As depicted in figs. 1 and 2, present embodiment discloses a kind of intensive pad high-density plate, comprise backing material plate 1, coverlay 2, ink layer and developing layer, backing material plate 1 is provided with part zone 11, coverlay 2 offers the district 3 of windowing of exposing part zone, district 3 area of windowing is greater than part zone 11, ink layer is covered in district 3 of windowing, developing layer is covered on ink layer ink layer exposure imaging, special less for part zone 11, the high-density plate that pad is comparatively intensive, some windows need not be offered, also avoid gap between window and window too small, affect the situations such as following process to occur.
The ink layer of the present embodiment adopts liquid photosensitive ink, and the full version printing of liquid photosensitive ink forms ink layer, and liquid photosensitive ink, after photo-curing, development, can etch, the process such as plating.Meanwhile, the developing layer of the present embodiment adopts film egative film.
Realize the windowing method of a kind of intensive pad high-density plate of the present embodiment, comprise the following steps:
Coverlay is fitted on backing material plate by 1;
The coverlay of 2 position, corresponding part zone offers the window region that area is greater than part zone, exposes whole part zone;
