The first metal forming 204, the second metal forming 205 are carried out pressing by the first metal forming applicator wheel 201, the second metal forming applicator wheel 202 with thermoplastic polyimide film applicator wheel 203 input heat pressure roller group 213a, 213b, 214a, 214b, 215a, 215b respectively with thermoplastic polyimide film 206.Wherein, the first metal forming 204 second metal formings 205 are more preferably Copper Foil nickel alloy foil or other metal formings.The first above-mentioned metal forming 204 and the second metal forming 205 need be selected the metal film of identical material, to avoid producing stress deformation because of the thermal coefficient of expansion difference.
In the present embodiment, can adjust on demand the angle that the first metal forming 204 and the second metal forming 205 import among the first heat pressure roller group 213a, the 213b, with the quality of better raising polyimides dual platen.As shown in Figure 2, the first metal forming 204 and the second metal forming 205 are to be imported among the first heat pressure roller group 213a, the 213b with an angle θ by the first metal forming guide wheel 209a, the second metal forming guide wheel 209b respectively.Wherein, above-mentioned angle θ is more preferably 5 ° to 45 °, but not as limit.Better can by the preheating device heat treated before thermoplastic polyimide film 206 is importing the first heat pressure roller group 213a, 213b, reduce the temperature difference of thermoplastics type's polyimide film and heat pressure roller group with this.Above-mentioned preheating device temperature is controlled between 150 ℃ to 200 ℃, and this preheating device is specifically as follows the ceramic-type air heating apparatus, but not as limit and the necessary temperature that can not surpass the first heat pressure roller group 213a, 213b.The first diaphragm 217 and the second diaphragm 218 import the first heat pressure roller group 213a, 213b by the first diaphragm applicator wheel 211 and the second diaphragm applicator wheel 212 through the first diaphragm guide wheel 210a, the first diaphragm guide wheel 210b respectively; wherein the first diaphragm and the second diaphragm are the heat pressure roller importing heat pressure roller groups that reclining fully, and diaphragm has good diathermancy and can protect goods to prevent from weighing wounded and oxidation.
The first metal forming 204, the second metal forming 205 are polyimide metal foil substrate 225 with thermoplastic polyimide film 206 through the first heat pressure roller group 213a, the preliminary pressing of 213b, wherein thermoplastic polyimide film 206 is between the first metal forming 204 and the second metal forming 205, and the width of polyimide film 206 needs the width less than the first metal forming 204 and the second metal forming 205.The first diaphragm 217 and the second diaphragm 218 are covered with the first metal forming 204, the second metal forming 205 and thermoplastic polyimide film 206 and import among the first heat pressure roller group 213a, the 213b in the mode that attaches in the present embodiment.The width of the first diaphragm 217 and the second diaphragm 218 needs the width less than the first metal forming 204 and the second metal forming 205.Above-mentioned the first heat pressure roller group 213a, 213b temperature are controlled between 220 ℃ and 250 ℃, and pressure is controlled to be about 0.8MPA, this scope not as the limit but need be no more than the second heat pressure roller group 214a, 214b.The polyimide metal foil substrate 225 that tentatively presses imports the second heat pressure roller group 214a, 214b with the first diaphragm 217 and the second diaphragm 218 and carries out further pressing, and wherein polyimide metal foil substrate 225 is between the first diaphragm 217 and the second diaphragm 218.The second heat pressure roller group 214a, 214b temperature are controlled between 250 ℃ and 300 ℃, and pressure is controlled to be about 0.9MPA, this scope not as the limit but need be no more than the 3rd heat pressure roller group 215a, 215b.After this polyimide metal foil substrate 225 that presses imports the 3rd heat pressure roller group 215a, 215b with the first diaphragm 217 and the second diaphragm 218 and carries out final pressing, and wherein polyimide metal foil substrate 225 is between the first diaphragm 217 and the second diaphragm 218.The temperature of the 3rd heat pressure roller group 215a, 215b is controlled between 300 ℃ and 380 ℃, and pressure is controlled to be about 1.0MPA, but this scope is not as limit.
Rolling is on goods winding wheel 226 behind the polyimide metal foil substrate 225 process cooling wheels 216 that finally pressing is good.The first diaphragm 217 and the second diaphragm 218 respectively rolling are taken turns on 224 in the 223 and second diaphragm rewinding of the first diaphragm rewinding wheel.Cooling wheel 216 does not contact with the first diaphragm 217 and the second diaphragm 218, in the mode of radiation the polyimide metal foil substrate 225 of deriving from the 3rd heat pressure roller group 215a, 215b is lowered the temperature, and the chilling temperature scope is 200 ℃ to 250 ℃.Thereby polyimide metal foil substrate 225 can directly be down to room temperature and cause shrinkage phenomenon to form wrinkle because of the 3rd heat pressure roller group 215a, the 215b from high temperature.
Therefore, in this embodiment, not only before the 3rd heat pressure roller group 215a, 215b, increase the second heat pressure roller group 214a, 214b and the first heat pressure roller group 213a, 213b and form the progressively effect of heating pressurization, further can carry out comprehensive hyperthermic treatment by 207 pairs of thermoplastic polyimide films of preheating device 206, and then effectively improve final pressing effect, more after triple heat pressure roller groups, set up a cooling wheel 216, and then the quality of goods after the Effective Raise pressing.
Above-described embodiment only is illustrative the utility model principle and effect thereof, but not is used for restriction the utility model.Rights protection scope of the present utility model should be listed such as claims.
