Description
Technical field
The utility model relates to printed circuit board field, is specially a kind of circuit board consent general-purpose and breathes freely backing plate.
Background technology
In the print production process of printed circuit board industry, for when preventing consent, ink diffuses to pad to limit, hole under the effect of scraper, two kinds of settling modes are generally selected at present.The first is at plate face underlay blank sheet of paper, often prints a slice pad a blank sheet of paper, tears blank sheet of paper again after printing.The drawback of this mode is, blank sheet of paper is easy to take aperture ink out of, and cause aperture quality abnormal such as rubescent grade, and operating process is loaded down with trivial details, efficiency is low.The second adopts special ventilative backing plate.Described special ventilative backing plate, although can solve the exception easily occurred in first kind of way, manufacture a finished product increase, needs extra each product to make backing plate specially, all have larger puzzlement to production, tool making storage and managenent etc.
Utility model content
The utility model object is for the above prior art Problems existing, provide a kind of structure simple, various lines plate can be adapted to make, the consent general-purpose of enhancing productivity is breathed freely backing plate.
In order to realize the utility model object, the timely scheme that the utility model is taked is: consent general-purpose is breathed freely backing plate, it comprises substrate and is deposited on the thick copper layer on substrate, described substrate is double face copper, receptacle region and marginal zone are wherein set, described thick copper layer is deposited on receptacle region, and described thick copper layer arranges some consent copper posts.
The thickness of described thick copper layer is 3-7 ounce.
Preferably, the thickness of described thick copper layer is 5 ounces.
Described consent copper post can be furnished with aperture and increase ring, for adapting to the hole in various aperture.
Between described consent copper post, gap is set, for ventilative.
Compared with prior art, the utility model has the advantages that: make simple, without special flow process; Easy to operate, do not change original operating type; Reduce work flow, do not need pad and tear blank sheet of paper, save the activity duration, enhance productivity, former every board produces jack panel 300PNL/ class, now can reach 800PNL/ class; Under effective minimizing, the use of pad blank sheet of paper, cost-saving.
Accompanying drawing explanation
Fig. 1 is plane graph of the present utility model;
Fig. 2 is cutaway view of the present utility model;
Fig. 3 is the plane graph that aperture increases ring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Consent general-purpose is breathed freely backing plate, and shown in Fig. 1-Fig. 3, it thick copper layer 12 comprising substrate 11 and be deposited on substrate, described substrate 11 is double face copper, wherein arranges receptacle region 2 and marginal zone 1, and the width of described marginal zone 1 is at 2-6cm.Described thick copper layer 12 is deposited on receptacle region 2, and described thick copper layer 12 arranges some consent copper posts 3.Wherein, the thickness of described thick copper layer 12 is 3-7 ounce.Preferably, the thickness of described thick copper layer 12 is 50 ounces.Described consent copper post 3 can be furnished with aperture and increase ring 4, for adapting to the hole in various aperture.Between described consent copper post 3, gap is set, for ventilative.
The breathe freely manufacture method of backing plate of consent general-purpose described in the utility model is as follows:
(1), according to size needs, sawing sheet is carried out to copper-clad plate;
(2) whole for double face copper plate plate face layers of copper is thickeied;
(3) to copper-clad plate pressing dry film, exposure, development;
(4) copper-clad plate is etched.
Above-mentioned, copper-clad plate size is larger than needing the board dimensions of consent;
Above-mentioned, double face copper layers of copper thickeies through plating mode, and copper is thick requires more than 5OZ;
Above-mentioned, copper-clad plate, in Graphic transitions process, adopts the film to carry out exposing or Direct Laser imaging;
Above-mentioned, the copper-clad plate surface through having etched Graphic transitions forms the copper post of multi-set parallel arrangement;
Above-mentioned, breathe freely when each copper inter-column gaps is used for consent.
Described general-purpose breathes freely backing plate using double face copper as making material, and specifically making step is as follows:
(1), when ensureing that backing plate effective dimensions reaches actual production board size, selecting optimum sawing sheet size, sawing sheet is carried out to copper-clad plate.
(2), in order to form the structure of similar spike on copper-clad plate plate face, need to thicken copper layer thickness.In the present embodiment, copper is thick reaches more than 5OZ to adopt the copper-plated mode of full plate to make.
(3), after the treatment step of copper-clad plate before the pad pastings such as nog plate, microetch, washing, dry plate, pressing photosensitive dry film, selects the film to carry out exposing or Direct Laser imaging, through developing, etching, move back film, completes the Graphic transitions of copper-clad plate.
Concrete, step (3) in, copper-clad plate is developed, removes the unexposed part of plate face photosensitive dry film; Exposed layers of copper etches through acidic etching liquid; Peel off the protection dry film covered in layers of copper moves back the effect of film liquid in alkalescence under.Wherein, described etching process, because layers of copper is thicker, needs repeatedly to have etched, and meanwhile, due to the lateral erosion effect of liquid medicine, the final plate face partial enlargement effect formed as shown in Figure 1.
This general-purpose breathes freely backing plate use simply, and backing plate gummed paper of being breathed freely by general-purpose is fixed on board, and directly at effective coverage internal fixtion location PIN, the contraposition of adjustment board can start to make.
As described above, be only the preferred embodiment that this is novel, when can not limit the scope of this novel enforcement with this, the simple equivalence change namely generally done according to this novel claim and novel description with modify, all still belong in scope that this new patent contains.
