Abstract
The utility model belongs to the technical field of film technique and specifically relates to a PCB film with function is detected partially in hole, including the interior film and the outer film, be provided with hollow ring on the frame between the interior film and the outer film, hollow ring is located the drilling position. The utility model discloses an invention aim at provide a PCB film with function is detected partially in hole, the utility model discloses simple structure, the cost of manufacture is low, adopts the utility model provides a technical scheme is being convenient for in the drilling, can also whether the off normal detects to the hole site.
Description
Technical field
The utility model relates to film technical field, specifically a kind of PCB film with the inclined measuring ability in hole.
Background technology
In PCB industry, the film is a kind of egative film for exposing.When doing pcb board, needing be coated with one deck photosensitive layer on pcb board surface, then being attached on pcb board with the film with map of current, then through ultraviolet exposure machine exposure, the circuit diagram on the film is developed on pcb board.
Along with the fast development of PCB industry, the live width line-spacing of pcb board is more and more less, and corresponding minimum cage ring is also more and more less, and in boring procedure, the inclined problem in hole happens occasionally.Testing tool for the inclined problem in hole has X-RAY, X-RAY transmitting tube produces X ray and passes through PCB, there is different uptakes to X ray according to the density of PCB own and atomic weight different and produce on picture receiver and project, the material shade that density is higher is darker, and therefore X-RAY can penetrate encapsulation inside and directly check the quality of quality of welding spot.But X-RAY can not judge that quality hidden danger is deposited in its hole partially whether intuitively, often there is difference when judging.
Utility model content
Goal of the invention of the present utility model is to provide a kind of PCB film with the inclined measuring ability in hole, the utility model structure is simple, cost of manufacture is low, adopts the technical scheme that provides of the utility model while being convenient to boring, can also whether off normal detects to position, hole.
In order to reach foregoing invention object, the utility model provides a kind of PCB film with the inclined measuring ability in hole, comprises the interior film and the outer film; Frame between the described interior film and the outer film is provided with cavity ring; Described cavity ring is positioned at bore position.
As further improvement of the utility model, the quantity of described cavity ring is 6, and is divided into 3 groups.
As further improvement of the utility model, the ring width of described cavity ring is 4mil; The annular diameters of described cavity ring is 0.8mm+4mil+N; Described N is the minimum cage ring value of product.Wherein 0.8mm is the aperture value of boring.
On the utility model film, the corresponding position in needs boring is provided with cavity ring, because this film is the negative film film, pcb board forms filled circles PAD after the etching, hole to pcb board in corresponding cavity ring position again, and whether the filled circles PAD directly with reference to pcb board destroys the effect that can reach and judge boring quality, does not need the product examine personnel of specialty, just quality hidden danger can whether be there is in position, intuitive judgment hole, not only improve detection efficiency, reduce enterprise's production cost, production quality can be taken into account simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.Apparently, the accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model example structure schematic diagram.
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.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.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.
Embodiment 1
As shown in Figure 1, present embodiment discloses a kind of PCB film with the inclined measuring ability in hole, comprise the interior film 10 and the outer film 20, the frame 30 between the interior film 10 and the outer film 20 is provided with cavity ring 40, and cavity ring 40 is positioned at bore position.The quantity of cavity ring 40 is 6, and is divided into 3 groups.The ring width of cavity ring 40 is 4mil, and the annular diameters of cavity ring 40 is 0.8mm+4mil+N, and wherein N is the minimum cage ring value of product.0.8mm is the aperture value of boring.
Because this film is the negative film film, pcb board forms filled circles PAD after the etching, and the annular diameters due to cavity ring 40 is 0.8mm+4mil+N, consider the side etching quantity of 1mil, the diameter of filled circles PAD is 0.8mm+3mil+N, and certainly, this side etching quantity is different because of different processing technology.
After etching, pcb board is carried out pressing boring, drilling data adds corresponding 0.8mm hole according to the position of cavity ring; After boring during X-RAY check-out console piece bores position, whether the direct filled circles PAD with reference to pcb board destroys the effect that can reach and judge boring quality, do not need the product examine personnel of specialty, just quality hidden danger can whether be there is in position, intuitive judgment hole, not only improve detection efficiency, reduce enterprise's production cost, production quality can be taken into account simultaneously.
Above-described execution mode, does not form the restriction to this technical scheme protection range.The amendment done within any spirit at above-mentioned execution mode and principle, equivalently to replace and improvement etc., within the protection range that all should be included in this technical scheme.
