7), peel off, the PET film base stock in the step 1 and aluminium foil layer or Copper Foil and compound with it antenna substrate layer PET film are separated, the aluminium foil layer of antenna pattern or copper foil layer and antenna substrate layer PET film are fixed together, and become the antenna stack finished product;
8), waste recovery, aluminium foil or Copper Foil and PET film base stock beyond the antenna pattern become waste material, rolling is got up.
Said method is that antenna substrate layer PET film adopts transfer method to make RFID antenna, can also use above-mentioned design, on antenna substrate layer paper base material, makes RFID antenna.
A kind of transfer type radio frequency identification read-write antenna making method is characterized in that, the present invention includes following steps:
1), aluminium foil layer or copper foil layer and PET film base stock are fitted, make to have the extremely low stripping power of drawing between aluminium foil layer or copper foil layer and the base stock, its draw stripping power size guarantee future during cross cutting aluminium foil or Copper Foil can not be shifted or come off;
2), die-cut antenna, cut out the shape of predefined antenna at aluminium foil layer or copper foil layer patrix;
3), the seal glue, the forme of glue is the same with the die-cutting rule version, guarantees to stamp uniformly on the antenna glue;
4), select paper roll as the antenna substrate layer material;
5), fit, above-mentioned antenna substrate layer paper and the aluminium foil layer or the copper foil layer that have printed glue are fit together;
6), heating cure, through heating, the glue curing on the antenna, antenna aluminium foil layer or copper foil layer and antenna substrate layer paper are fixed together closely;
7), peel off, the PET film ground paper layer in antenna substrate layer paper and aluminium foil or Copper Foil and the step 1 is separated, the aluminium foil of antenna pattern or Copper Foil and antenna substrate layer paper are fixed together and become the antenna stack finished product;
8), aluminium foil beyond the antenna pattern in the above-mentioned steps or Copper Foil and PET film ground paper layer become the waste material rolling.
Described aluminium foil layer or copper foil layer thickness are the 0.007-0.009 millimeter; Because it is too thin; Cross cutting aluminium foil or Copper Foil are very strict to the requirement of cutter separately, and the mechanical strength of aluminium foil or Copper Foil is very low, are easy to take place fold or fracture; So the aluminium foil or the Copper Foil production efficiency of cross cutting 0.007-0.009 millimeter are low separately, and is infeasible on the technology.
The aluminium foil of 0.007-0.009 millimeter or Copper Foil and PET counterdie (base stock) are fit together; Can improve the mechanical stability of aluminium foil or Copper Foil greatly; Because the thickness of PET counterdie (base stock) is greater than aluminium foil or copper thickness; Die-cutting rule is cut aluminium foil or Copper Foil, and cutting knife can not damage cutter yet, can guarantee large batch of high efficiency die-cutting production radio-frequency antenna.
According to above-mentioned design; The complex of aluminium foil or Copper Foil and PET counterdie (base stock); After aluminium foil or Copper Foil cross cutting; Unnecessary aluminium foil or Copper Foil beyond the radio-frequency antenna are disposed, adopted shifting process that aluminium foil or copper foil antenna part are separated with the part beyond the antenna, above-mentioned design has dual mode:
1, antenna part is transferred on the antenna substrate layer PET film, becomes antenna stack.Aluminium foil beyond the antenna part or Copper Foil, PET counterdie become waste material, and rolling is got up.
2, the part beyond aluminium foil or the copper foil antenna is transferred on the PET counterdie, becomes the waste material rolling, and the antenna part of aluminium foil or Copper Foil is stayed on the PET counterdie, becomes antenna stack.
Any mode all need be after cross cutting at used aluminium foil or Copper Foil and PET counterdie composite bed; Can strip down aluminium foil behind the cross cutting or Copper Foil (part beyond antenna or the antenna) smoothly; So; The compound peeling strength (drawing stripping power) of aluminium foil or Copper Foil and PET counterdie is can not ether big, otherwise aluminium foil or Copper Foil can not separate transfer with the PET counterdie.
Obviously, the second way, transferring to the part beyond the antenna on the PET counterdie becomes waste material, and antenna part is stayed on the PET counterdie becomes antenna stack, and the applying intensity of aluminium foil or copper foil antenna and PET counterdie is lower, can have influence on the stability of antenna stack.
In addition, for the cross cutting stability of the aluminium foil that guarantees the 0.007-0.009 millimeter or Copper Foil, it is big that the thickness of PET counterdie is wanted; Like the 0.03-0.05 millimeter; If adopt antenna stack to stay on the PET counterdie, the thickness of antenna stack is too big, can have influence on the quality of next packaging process.
And transfer to aluminium foil or copper foil antenna layer on the PET counterdie, the thickness of PET film does not influence the aluminium foil transfer effect, can use very thin PET counterdie, as 0.01 millimeter, even thinner counterdie, improves the package quality of radio frequency products greatly.
As stated, the aluminium foil antenna part not only can be transferred on the PET counterdie, and can transfer on the paper, becomes the papery antenna stack, is convenient to make radio frequency read-write ticket, card.
According to the present invention of above-mentioned process, solved the problem that traditional etching antenna exists:
1, do not have the optical exposure photographic fixing, without chemical etching liq, adopt the method for cross cutting to make antenna, operational environment and natural environment are not polluted, aluminium foil in the waste material or Copper Foil can be recycled.
2, continuous cross cutting, operating rate can reach more than 80 meters/minute, and production cost is significantly less than etching antenna.
3, die-cut antenna technology is simple, very easily with the online production line that becomes of other technologies: as with chip fall encapsulation be linked together, become radio frequency and read and write product line.Improve radio frequency read-write production efficiency of products.
4, can on paper substrate or PE, PVC film or other synthetic papers, make antenna.
