Description
Technical field
The utility model protects membrane stability bonding structure more particularly to a kind of FPC, belongs to flexible circuit board technical field.
Background technique
With the intelligentized development of electronic equipment, flexible circuit board is as the important load for realizing electronic equipment correlation function
Body plays more and more crucial effect in current field of electronic device.
Because of increase or the needs of function, the wiring and pad in flexible circuit board are closer and closer, and insulating layer is caused to be opened
Window is offline or mode of the more and more nearlyr insulation sandwich circuit with a distance from pad there are two types of, one is only protected with polyimides
Cuticula, one is polyimides protective films, and solder mask to be added to expose.When insulating layer windowing is offline or close from pad pitch, because
The harmomegathus characteristic of polyimides protective film, when especially windowing area is big, fitting protective film is easy to deviation, often will
Route exposes or covers pad, seriously affects the quality of flexible circuit board.To solve this problem often through polyimides
Protective film adds the mode of solder mask exposure to solve the problems, such as this, but the method will increase process and raw material, increases cost.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of FPC protection membrane stability fitting
Structure improves protective film Anawgy accuracy and dimensional stability, promotes flexible circuit board by changing structure when protective film fitting
Quality can effectively solve the problems in background technique.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model provides a kind of FPC protection membrane stability bonding structure, including protective film, carrier film and windowing, institute
It states the upper surface of protective film and presses one layer of colored carrier film, the top of the carrier film is equipped with windowing, the protective film and carrying
Film for fitting in flexible circuit board together.
As a kind of optimal technical scheme of the utility model, the protective film thickness range is 22um-100um.
As a kind of optimal technical scheme of the utility model, resistance to 200 DEG C of the high temperature of carrier film.
As a kind of optimal technical scheme of the utility model, the carrier film with a thickness of 0.05-0.06mm.
As a kind of optimal technical scheme of the utility model, the top of the carrier film and protective film is drilled with hole.
The utility model beneficial effect achieved is: one layer of colored carrier film of face pressure on protective film, increases and protects
Film strength and hardness are protected, in this way, protective film will not shake when fitting, the precision of protective film fitting is improved, does not increase protection
In the case where film, general Anawgy accuracy can only accomplish 0.15-0.20mm, and after increasing carrier film, Anawgy accuracy can be accomplished
0.010mm is that carrier film removes unclean undiscovered and flow to client in order to prevent using colored carrier film.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.
In the accompanying drawings:

3, the protective film 1 and carrier film 2 for fitting in flexible circuit board together.
Further, 1 thickness range of protective film is 22um-100um.
Further, the high temperature of 2 resistance to 200 DEG C of the carrier film.
Further, the carrier film 2 with a thickness of 0.05-0.06mm, too thick, punching can be easy to produce flash, too
Bao Liao does not have the effect of support.
Further, the top of the carrier film 2 and protective film 1 is drilled with hole, and the off-type force of carrier film will be controlled in 8g
Left and right, it is too big to be not easy to remove, it is too small, it has been easy bubble between carrier film and protective film, has influenced quality.
It should be noted that the utility model is that a kind of FPC protects membrane stability bonding structure, in use, in protective film
One layer of colored carrier film of upper pressure has following the most key requirement to carrier film, and carrier film will be resistant to 200 DEG C of high temperature,
It is required that carrier film with a thickness of 0.05-0.06mm, too thick, punching can be easy to produce flash, too thin, not have the effect of support
Fruit, the off-type force of carrier film will be controlled in 8g or so, too big to be not easy to remove, too small, be held between carrier film and protective film
Bubble is tended to have, quality is influenced, colored carrier film and protective film drill together, drill out the hole of needs, carrier film and protection
It is punched together, goes out the window for needing to open a window, carrier film and protective film are fitted in flexible circuit board together, high-temperature laminating is protected
Cuticula and carrier film.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
