Description
Technical Field
The present invention relates to a manufacturing apparatus of metal foil laminated plate, and more particularly to a manufacturing apparatus of thickened metal foil laminated plate.
Background
Regarding a Flexible Printed Circuit (FPC), which is also called a Flexible copper foil substrate, after exposure, development and etching processes, a Circuit lead with a desired design is obtained, which can be used as a medium for transmitting a current signal of an electronic product. Flexible Printed Circuit (FPC) has the characteristics of flexibility, thinness, shortness, and smallness, and is also called flexible pcb, and related products are roughly classified into single panel, double-sided board, multi-layer board, and the like.
Since the Flexible Printed Circuit (FPC) has various characteristics such as flexibility, lightness, thinness, shortness, anti-static property, low power consumption and capability of changing according to space design, the application market of the FPC is increasing and has a huge market potential while the trend of lightness, thinness, shortness and bending resistance is emphasized in today's electronic products.
A Flexible Copper Clad Laminate (FCCL) is a processing substrate of a Flexible printed circuit board (FPC). Depending on whether it contains an adhesive, it can be divided into: a glue three-layer flexible copper clad laminate (3L-CCL) and a glue-free two-layer flexible copper clad laminate (2L-FCCL). The adhesive three-layer flexible copper clad laminate (3L-CCL) contains an adhesive, so that the application is more limited due to the poor performance items, such as dimensional stability and heat resistance; as for the non-adhesive double-layer flexible copper foil substrate (2L-FCCL), not only has excellent performance in dimensional stability and heat resistance, but also includes fine circuit preparation capability, compared with the adhesive substrate, the non-adhesive double-layer flexible copper foil substrate has better circuit resolution, good heat resistance, good dimensional stability, electrical characteristics, bending resistance and reliability, and also improves the application range of FPC products.
Although the conventional adhesive-free double-layer flexible copper clad laminate (2L-FCCL, hereinafter referred to as double-layer flexible copper clad laminate) can be manufactured by using special equipment, the supplier of the plastic resin adhesive layer in the conventional adhesive-free double-layer flexible copper clad laminate (2L-FCCL) can only manufacture the plastic resin adhesive layer with the thickness of less than 50 μm, and the requirement of the present customers on the use of thick-specification new products cannot be met. In other words, the supplier cannot manufacture the plastic resin adhesive layer with a thickness of more than 50 μm by the prior art, which is a problem that the present inventors want to solve.

Detailed Description
The following detailed description and technical contents of the present invention are described with reference to the drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.
The utility model provides a manufacturing device of thickened metal foil laminated plate, which is used for manufacturing a non-adhesive double-layer double-sided flexible metal foil laminated plate (hereinafter referred to as double-sided metal foil laminated plate) with required thickness.
As shown in fig. 1 to 3, a first embodiment of a manufacturing apparatus for a thickened metal-foil laminated plate (hereinafter referred to as a manufacturing apparatus) according to the present invention includes: a feeding wheel set 1 and a hot pressing wheel set 2, preferably further comprising: two protective layer take-up wheels 3, a semi-finished product take-up wheel 4a, a semi-finished product supply wheel 4b, a semi-finished product supply structure 5, a width cutter 6 and a finished product take-up wheel 8. Fig. 1 shows a front part of a first embodiment of the manufacturing apparatus of the present invention for manufacturing a double-sided metal-foil laminate; fig. 2 shows a rear portion of a first embodiment of the manufacturing apparatus of the present invention for cutting the manufactured double-sided metal-foil laminate into a desired width.
The front part of fig. 1 includes the feeding wheel set 1, the hot press roller set 2, the protective layer receiving wheel 3 and the semi-finished product receiving wheel 4a, which are described in detail as follows (as for the rear part of fig. 2, the semi-finished product feeding wheel 4b, the semi-finished product feeding structure 5, the width cutter 6 and a finished product receiving wheel 8 are included).
The feed wheel group 1 comprises: a first feeding wheel 11, a second feeding wheel 12, a third feeding wheel 13, a fourth feeding wheel 14, a fifth feeding wheel 15 and a sixth feeding wheel 16, which are used for outputting six layers of materials.
The first and second material supplying wheels 11 and 12 respectively output two protective layers L1 and L2 located at the outermost two layers (i.e., the first and sixth layers shown in fig. 1); the third and fourth feed wheels 13 and 14 output two metal foils L3 and L4 located at the next two layers (i.e., the second and fifth layers shown in fig. 1), respectively; the fifth and sixth supply wheels 15 and 16 output two thermoplastic resin adhesive layers L5 and L6 located in the middle two layers (i.e., the third and fourth layers shown in fig. 1), respectively. It should be noted that the two thermoplastic resin adhesive layers L5, L6 overlap each other and jointly go around the same path after being delivered by the fifth and sixth feeding rollers 15, 16 and before being thermally pressed by the hot press roller set 2.
The metal foils L3, L4 may be any metal foil, for example: copper foil or aluminum foil, but not limited thereto. The thermoplastic resin bonding layers L5 and L6 may be any resin having thermoplastic properties and being used for bonding, for example, thermoplastic Polyimide (PI) film having good high and low temperature resistance, environmental stability, mechanical properties and excellent dielectric properties; the thermoplastic resin adhesive layers L5 and L6 may also be Liquid Crystal Polymer (LCP) films, which are thermoplastic organic materials having characteristics of low moisture absorption, good chemical resistance, high gas barrier properties, low dielectric constant/dielectric loss factor, and good bendability; however, the present invention is not limited to Polyimide (PI) films or Liquid Crystal Polymer (LCP) films.
The thermocompression bonding roller set 2 thermocompresses the two protective layers L1, L2, the two metal foils L3, L4 and the two thermoplastic resin adhesive layers L5, L6 stacked on each other to form a thickened double-sided metal foil laminate D (having the two protective layers L1, L2). Therefore, at this time, the thermoplastic resin adhesive layers L5 and L6 are respectively bonded and fixed to the rough surfaces of the metal foils L3 and L4, and the two thermoplastic resin adhesive layers L5 and L6 are bonded and fixed to each other by controlling the temperature and other parameters during the production.
It should be noted that the original surfaces (original film surfaces) of the thermoplastic resin bonding layers L5 and L6 themselves are smooth and plastic, and although the thermoplastic resin bonding layers are bonded and fixed to the material with the rough surface at a certain high temperature, the bonding property between the smooth original surfaces of the two thermoplastic resin bonding layers L5 and L6 is rather weak, so the present invention needs to add a method or structure capable of enhancing the bonding force, as described in detail in the following.
In order to enhance the bonding force, the two thermoplastic resin bonding layers L5, L6 are bonded and fixed to each other by controlling the temperature and other parameters during the production process, as mentioned above. In the structure capable of enhancing the bonding force of bonding, as shown in fig. 3, each of the thermoplastic resin bonding layers L5 and L6 has two surfaces opposite to each other, and each surface is subjected to a surface treatment for enhancing the bonding force in advance to form a bonding enhanced surface F; in this way, the two thermoplastic resin adhesive layers L5 and L6 can be tightly bonded and fixed to each other via the bonding reinforcement surfaces F adjacent to each other, and the two thermoplastic resin adhesive layers L5 and L6 are tightly bonded and fixed to the metal foils L3 and L4 via the bonding reinforcement surfaces F away from each other.
Therefore, the utility model utilizes the characteristic that the thermoplastic resin bonding layers L5 and L6 can generate enough bonding force under specific conditions or after the bonding reinforcing surface F is added, and simultaneously, at least two thermoplastic resin bonding layers L5 and L6 are laminated to form a thickened metal foil laminated plate (namely a thickened double-sided metal foil laminated plate D) together with other layers after hot pressing. Therefore, the present invention can not only simply laminate at least two thermoplastic resin adhesive layers to increase the thickness, but also ensure that the formed thickened metal foil laminate does not peel between any two adjacent thermoplastic resin adhesive layers L5 and L6.
Note that, the thermoplastic Polyimide (PI) films used in the thermoplastic resin adhesive layers L5 and L6 are abbreviated as: TPI; the double-sided metal foil laminated plate D manufactured as described above is abbreviated by english as: 2 LD-FCCL.
Preferably, the first embodiment of the manufacturing apparatus of the present invention further includes two protective layer take-up wheels 3 and a semi-finished product take-up wheel 4a as seen in fig. 1, and a semi-finished product supply wheel 4b, a semi-finished product supply structure 5, a width cutter 6, and a finished product take-up wheel 8 as seen in fig. 2.
The width cutter 6 is located between the semi-finished product feeding structure 5 and the finished product take-up wheel 8 in the rear section as shown in fig. 2, and the width cutter 6 is used to cut the double-sided metal foil laminate D into a desired width.
The two protective layer receiving wheels 3, the semi-finished product receiving wheel 4a and the semi-finished product feeding structure 5 are all located behind the hot pressing roller group 2 and are all located in front of the width cutter 6. As shown in fig. 1, the two protective layer take-up wheels 3 take up the two protective layers L1 and L2, respectively, of the double-sided metal-foil laminate D, so that the double-sided metal-foil laminate D becomes a double-sided metal-foil laminate D (not having the two protective layers L1 and L2, the remaining part of the double-sided metal-foil laminate D not having the two protective layers L1 and L2 is the double-sided metal-foil laminate D) and is taken up by the blank take-up wheel 4 a.
The semi-finished product take-up wheel 4a is arranged on the semi-finished product feeding structure 5 to become a semi-finished product feeding wheel 4 b. The blank feeding wheel 4b feeds the rolled double-sided metal foil laminated sheet d to the width cutter 6. The width cutting device 6 cuts the double-sided metal-foil-laminated sheet d having no protective layers L1 and L2 to a desired width.
The product take-up wheel 8 is located behind the width cutter 6, and the product take-up wheel 8 is used to roll up the double-sided metal foil laminate (i.e. the aforementioned thickened metal foil laminate) cut to the desired width.
In addition, in order to achieve the best bonding and fixing effect, the present invention can increase or decrease the curing time required for the different thermoplastic resin bonding layers L5, L6 to pass through the rollers by controlling the number of the rollers after the hot pressing roller set 2, so as to achieve the best bonding and fixing effect. The position design of the roller can be changed according to the size of the space (such as the internal space of a factory building).
Fig. 4 shows a second embodiment of the manufacturing apparatus of the present invention, which is substantially the same as the first embodiment, and the only difference is that the second embodiment is an integrated apparatus without front and rear sections, and therefore, the second embodiment does not include the semi-finished product receiving wheel 4a, the semi-finished product feeding wheel 4b and the semi-finished product feeding structure 5 in the first embodiment.
In other words, in the second embodiment, the double-sided metal-foil-laminated sheet d is directly output to the width cutter 6, and the blank receiving wheel 4a, the blank feeding wheel 4b and the blank feeding structure 5 in the first embodiment are not required at all, thereby reducing the equipment cost.
It should be understood that the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the specification and drawings are included in the scope of the present invention.
