Abstract
The utility model discloses a kind of FPC industries pure copper foil new technological flow producing device, including light source and egative film, the egative film is located at light source output end, the egative film bottom is provided with dry film, and the dry film bottom is provided with pure copper foil, and the pure copper foil fits with dry film, the pure copper foil bottom is provided with PET carrier films, the PET carrier films fit with pure copper foil, and the utility model is that process fabrication cycle can shorten 30% before new technological flow, circuit；Design finger line width unrestricted to cover layer Edge Distance, hollow out state is not present in finger circuit during etching；Circuit process fabrication material can save 50%, the exposure station time can save 50%.
Description
Technical field
The utility model is related to Flexible Printed Circuit (printing printing immunity wiring board) sector application neck
Domain, more particularly to a kind of FPC industries pure copper foil new technological flow producing device.
Background technology
It is well known that current industry pure copper foil（Hollowed-out board）Circuit technique thereof flow：Sawing sheet -- baking -- pastes bottom cover layer（Cover
Epiphragma cuts-cover layer drilling-cover layer outline die）-- -- -- Chemical cleaning is -- two-sided to press dry film -- to expose for baking for pressing
Light -- DES-lower process pressing cover layer；It has the drawback that：Flow fabrication cycle is long, and cost is too high, during laminating film
Step bubble can not prevent at bottom cover layer opening, and quality yield is too low and finger line width is limited to cover layer Edge Distance
System, therefore, invents a kind of FPC industries pure copper foil new technological flow producing device necessary to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of FPC industries pure copper foil new technological flow producing device, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of FPC industries pure copper foil new technological flow
Producing device, including light source and egative film, the egative film are located at light source output end, and the egative film bottom is provided with dry film, the dry film
Bottom is provided with pure copper foil, and the pure copper foil fits with dry film, and the pure copper foil bottom is provided with PET carrier films, the PET carryings
Film fits with pure copper foil.
It is preferred that, the PET carrier films input is provided with PET carrier film cutting means.
Technique effect of the present utility model and advantage：This invention is new technological flow, and process fabrication cycle can contract before circuit
It is short by 30%；Design finger line width unrestricted to cover layer Edge Distance, hollow out state is not present in finger circuit during etching；Circuit
Process makes that material can save 50%, the exposure station time can save 50%.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
In figure：1- light sources, 2- egative films, 3- dry films, 4- pure copper foils, 5-PET carrier films.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of FPC industries pure copper foil new technological flow producing device as shown in Figure 1, including light
Source 1 and egative film 2, the egative film 2 are located at the output end of light source 1, and the bottom of egative film 2 is provided with dry film 3, and the bottom of dry film 3 is provided with
Pure copper foil 4, the pure copper foil 4 fits with dry film 3, and the bottom of pure copper foil 4 is provided with PET carrier films 5, the PET carrier films 5
Fitted with pure copper foil 4.
In addition, the above-mentioned input of PET carrier films 5 is provided with PET carrier film cutting means, be conducive to making carrier film using effect
More preferably.
This practical operation principle：Flow after change is：
Glue PET carrier films in sawing sheet --- pressing bottom（Glue PET carrier films and cut in bottom）- single sided lamination dry film-exposure --
DES-tear carrier film-lower process pressing cover layer；The procedure of main flow 9, the procedure of auxiliary material flow 3 before optimization；After optimization：It is main
Flow is 7 procedures, the procedure of auxiliary material flow 1；Be before process optimization dual sided lamination dry film, optimization after be single sided lamination dry film,
Dry film cost savings 50%, time for exposure shorten 50%.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
It should be included within protection domain of the present utility model.
