Description
Technical field
The utility model relates to a kind of hot roll extrusion and closes equipment, especially belongs to a kind of hot roll extrusion for preparing the polyimide foil laminated plates and closes equipment.
Background technology
Polyimide copper foil laminates is the material of a flexible printed circuit, can generally be divided into the three ply board that the glue formula is arranged and not have two laminates of glue formula.The preparation method that the three ply board of glue formula is arranged mainly is to use adhesion agent layer to cohere polyimide film and Copper Foil.And do not have the preparation method of two laminates of glue formula, and be earlier the precursor solution of polyimides to be coated copper foil surface, make the precursor solution of polyimides change into polyimides through high-temperature chemical reaction again, be used on copper foil surface, forming one deck polyimide film.Compared to the three ply board that the glue formula is arranged, two laminates of no glue formula have thin, durable advantage, thereby are used widely.Moreover, again since many electronic products requires gradually toward meticulous small and exquisite development, so a kind of manufacture method of not having a two-sided copper foil laminates of glue formula polyimides then in response to and give birth to.
The preparation method of the two-sided copper foil laminates of known polyimides mainly is prior to reel respectively on the feed wheels two Copper Foils and thermoplastic polyimide film, then two Copper Foils is fitted in the upper and lower surface of thermoplastic polyimide film respectively.Then, after guide wheel group adjustment, alignment, enter hot roller set, with the two-sided copper foil laminates of the incompatible formation polyimides of hot pressing.Yet, because the Copper Foil in the two-sided copper foil laminates of known polyimides and the thickness of thermoplastic polyimide film are all extremely thin, adding again that hot roll extrusion is closed normally turns round under quite high rotating speed, so Copper Foil and thermoplastic polyimide film tend to produce because of running up tension variation.Moreover, because the surface temperature of hot roller set has at least more than 280 ℃,, can produce stress again because of thermal expansion effects so coating materials that ought be colder directly contacts the hot roller set of high temperature, as long as so a little stress difference is arranged, metal forming and thermoplastic polyimide film just may produce fold.
In view of this, a kind of hot roll extrusion of Improvement type is closed machine and then is developed.Please refer to Fig. 1, it is the structural representation that machine is closed in a kind of known hot roll extrusion.In Fig. 1, carrying out before hot roll extrusion closes processing procedure at coating materials such as metal forming 102a, 102b and thermoplastic polyimide films 104, allow metal forming 102a, 102b earlier through preheating guide wheel 106, to dwindle the temperature difference between metal forming 102a, 102b and the hot roller set 108 earlier.Yet equipment is closed in this known hot roll extrusion has a difficulty to be, in case leave after the preheating guide wheel 106 through metal forming 102a, the 102b of preheating, the temperature stability of metal forming 102a, 102b just is difficult to control, and then causes follow-up hot pressing effect instability.Thus, then be difficult to the effectively quality of the two-sided copper foil laminates of control polyimides.
Therefore, need a kind of hot roll extrusion of improvement to close method, to solve the above problems.
Summary of the invention
