The specific embodiment
In order more to make much of the technology contents of the utility model, below in conjunction with specific embodiment the technical scheme of the utility model is further introduced and explanation, but be not limited to this.
As shown in Figure 1, a kind of FCCL precast construction A with two adhesive layers of the utility model comprises substrate layer 10, and substrate layer 10 is a polyimide film, the preferred thermoplastic polyimide film.The both sides of substrate layer 10 are provided with adhesive layer 11A, 11B, and the outside of adhesive layer 11A, 11B is provided with adherent layer 12,13. Adherent layer 12,13 is the release liners (again be called separate paper or barrier paper, by the paper that scribbles preventing viscosity substance processed, also can adopt mould release membrance) of thickness between 30-260 μ m.Wherein, the thickness of adhesive layer is 8-120 μ m, and the preferred epoxy halogen-free flameproof of adhesive layer glue-line.
As shown in Figure 2; A kind of production equipment with FCCL precast construction of two adhesive layers of the utility model comprises the stock shelf 2 that sets gradually, encapsulating machine 3, glue spreader 4, first baking oven 5, release liners bin 6, is laminated with machine 7 (can be described as compounding machine again) and rewinding frame 8.Also comprise second baking oven 9.Also comprise frame S, the top of frame S is provided with aforesaid encapsulating machine 3, glue spreader 4, first baking oven 5, release liners bin 6 and is laminated with the below that machine 7, the second baking ovens 9 are located at frame S, and stock shelf 2 and rewinding frame 8 are located at the two ends of frame S.Second baking oven 9 is provided with charging aperture 91 that connects with rewinding frame 8 and the discharging opening 92 that connects with stock shelf 2.Second baking oven 9 is provided with the transmission guide rail 93 that is connected between charging aperture 91 and the discharging opening 92.The below of second baking oven 9 is provided with the actuating unit (not shown, as to generally include parts such as motor, reducing gear and drive) that is used to drive transmission guide rail 93.
The technology and the method for FCCL precast construction are following: earlier hot polymerization acid imide film is used as base material, is loaded on stock shelf, be coated with the adhesive layer of one deck 8-120um with coating machine (being glue spreader 4), in 40 ℃ of-260 ℃ of horizontal baking ovens (i.e. first baking oven 5), toasted 2-12 minute; Use the release liners (perhaps mould release membrance) of the compound one deck 30-260um of compounding machine again, obtain three layers of semi-finished product; Again three layers of half-finished polyimides face are coated with the adhesive layer of one deck 8-120um with coating machine, in 40 ℃ of-260 ℃ of horizontal baking ovens (i.e. first baking oven 5), toasted 2-12 minute; Use the release liners (perhaps mould release membrance) of the compound one deck 30-260um of coating machine again; Put into baking oven (second baking oven 9); Make pressure sensitive adhesive double coated stick be in semi-cured state in 2-28 hour through 30 ℃-160 ℃ bakings, thereby obtain having the polyimides FCCL new material of two adhesive layers.Wherein, after compound release liners for the first time, second baking oven is not worked, and just wherein transmission guide rail can be used to transmit three and leads semi-finished product, and after compound release liners for the second time, second baking oven is launched heating work again.Because the time ratio of first heating is shorter; Heat time heating time, (promptly 30 ℃-160 ℃ were toasted 2-28 hour) was long for the second time; Since Compound Machining all be one involve in capable; When therefore after multireel PI film is compound through secondary, heating for the last time again, need before to accomplish re-compounded FCCL and place in second baking oven, the wait later stage accomplishes re-compounded FCCL and heats (promptly 30 ℃-160 ℃ were toasted 2-28 hour) together for the last time.When this processing mode of needs; Can in second baking oven, be provided with two transmission guide rail, wherein, first transmission guide rail is used to transmit three layers of semi-finished product after for the first time compound; First transmission guide rail can be located at the casing outside of second baking oven, also can pass the casing of second baking oven.Second transmission guide rail will be accomplished the compound FCCL afterwards of secondary and transfer in second baking oven.For reducing production cost, the structure that preferentially adopts two transmission guide rail to be arranged side by side, a shared actuating unit.
In addition, because frame is established De Taigao, be unfavorable for the maintenance of equipment; And cause equipment cost too high, thus can second baking oven be located at the side of frame, rather than the bottom; Like this; The main stand of equipment can be done lowlyer, helps regular maintenance, also helps reducing the production cost (shape of frame can be dwindled) of equipment.
In sum; The utility model has adopted the structure that is provided with adhesive layer and adherent layer in PI film both sides; Make it to become a kind of double faced adhesive tape material that is exclusively used in wiring board processing; The copper that covers that makes FPC manufacturer can carry out the later stage by the electronic circuit of own product is processed, and can reduce the production cost of FPC widely.Both can cover copper by single face, also can double-sided copper-clad; When carrying out double-sided copper-clad, can become two-sided FPC, when carrying out single face when covering copper, another adhesive layer of PI film can be used for being adhesively fixed of FPC, when FPC being used for LED lamp band, can FPC be fixed on the carrying object surface by another adhesive layer.The utility model not only can be applied to the LED lighting field, and can extensively be generalized to fields such as electronic product, space flight and aviation, medicine equipment.This material can reduce the manufacturing cost of FPC greatly, has accelerated the extensive use of FPC in the electronic product field.
The above only further specifies the technology contents of the utility model with embodiment; So that the reader is more readily understood; But do not represent the embodiment of the utility model to only limit to this, any technology of doing according to the utility model is extended or recreation, all receives the protection of the utility model.
