Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.
Fig. 4 shows the schematic diagram of a kind of aluminium etching antenna card in the utility model embodiment, this card mainly comprises polyester film antenna stack 1, cover layer and glue-line 4 three parts, wherein, cover layer comprises upper caldding layer 2 and lower caldding layer 3, polyester film antenna stack 1 comprises polyester film and is fixed on the aluminium etching antenna coil on polyester film, polyester film antenna stack 1 has hollow out 5, as shown in Figure 5, glue-line 4 is arranged between upper caldding layer 2 and polyester film antenna stack 1 and/or between lower caldding layer 3 and polyester film antenna stack 1, upper caldding layer 2 when becoming to block, polyester film antenna stack 1, glue-line 4 and lower caldding layer 3 hot pressing, as shown in Figure 4.
Glue-line 4 can adopt two kinds of forms, a kind of form is glue-line 4 is independent layers of two-sided, as PET base material double faced adhesive tape, as shown in Figure 4, now, glue-line 4 generally only needs one deck, be arranged between upper caldding layer 2 and polyester film antenna stack 1 or be arranged between lower caldding layer 3 and polyester film antenna stack 1, when becoming card, according to the order hot pressing of upper caldding layer 2, glue-line 4, polyester film antenna stack 1 and lower caldding layer 3 or the order hot pressing according to upper caldding layer 2, polyester film antenna stack 1, glue-line 4 and lower caldding layer 3.
The another kind of form of glue-line 4 is glue-lines that on face that above and/or under the face by contacting with polyester film antenna stack 1 at upper caldding layer 2, cover layer 3 contacts with polyester film antenna stack 1, brush coating is formed, namely at a brush coating of upper caldding layer 2 and/or lower caldding layer 3, now, generally can at upper caldding layer 2 and equal brush coating in the one side contacted and in the one side that contacts with polyester film antenna stack 1 of lower caldding layer 3, when becoming card, according to the order hot pressing of upper caldding layer 2, polyester film antenna stack 1 and lower caldding layer 3.
When actual fabrication, the form of preferred glue-line 4 is above-mentioned first kind of way, as shown in Figure 4.In present embodiment, the aluminium etching antenna coil of polyester film antenna stack 1 is fixed on polyester film by glue, hollow out on polyester film antenna stack 1 is positioned at the middle part of polyester film antenna stack, concrete, inside the aluminium etching antenna coil of polyester film antenna stack 1, there is hollow out 5, wherein, hollow out 5 can be by coil inside whole region carried out hollow out, as shown in Figure 5, also side region multiple discontinuous hole can be offered in coil, preferably whole region hollow out.
When glue-line 4 is an independent layers of two-sided, as shown in Figure 4 and Figure 6, in present embodiment, the overall dimension of glue-line 4 is less than tectal overall dimension (tectal size is the size of card), is greater than the overall dimension of polyester film antenna stack 1.By glue-line 4, upper caldding layer 2 and upper caldding layer 3 can better be bondd in the process being laminated into card.Now, occur significantly protruding after card forming in the position of aluminium etching antenna coil, position (circumference of glue-line 4) corresponding with aluminium etching antenna coil on glue-line 4 has hollow out 6, in order to easy to process, hollow out 6 on glue-line 4 is discontinuous hollow out, as shown in Figure 6, in figure, white openwork part is hollow out 6, other dash area 7 is actual glue-line, and the size of glue-line 4 hollow out inboard portion (the glue-line mid portion shown in Fig. 6) is less than hollow out 5 size on polyester film antenna stack 1.
In present embodiment, polyester film antenna stack 1, cover layer and glue-line 4 the profile of three parts be all made into quadrangle, the overall dimension of glue-line 4 is less than tectal about overall dimension 1mm, and the length and width of glue-line 4 hollow out inboard portion are all less than each about the 1mm of length and width of the openwork part on polyester film antenna stack 1.
Manufacturing process below in conjunction with the utility model aluminium etching antenna card is further described card, and its making step comprises:
(1) first, adopt existing method to make aluminium etching antenna, and aluminium etching antenna coil glue is fixed on polyester film, make polyester film and coil become overall, form polyester film antenna stack 1;
(2) by polyester film antenna stack 1 middle part (inside aerial coil) hollow out, as shown in Figure 5;
(3) glue-line 4 is made, in ability mode, when glue-line 4 is independent layers of two-sided, glue-line 4 overall dimension is less than finished product card about overall dimension 1mm, glue-line 4 is die-cut into the pattern shown in Fig. 6 according to actual conditions, the hollow out position of glue-line 4 is corresponding with the coil position of polyester film antenna stack 1, and the length and width of hollow out inboard portion are less than each about the 1mm of polyester film antenna openwork part length and width;
(4) upper caldding layer 2, polyester film antenna stack 1, glue-line 4 and lower caldding layer 3 is carried out hot pressing and be formed into card, as shown in Figure 4.
Aluminium etching antenna card of the present utility model is by carrying out hollow out by polyester film antenna stack mid portion, and by increasing glue-line, upper and lower substrate layer (cover layer) can be bondd by glue-line, strengthen between upper and lower substrate layer and connect, efficiently solve the lamination problem between polyester film antenna stack and upper and lower substrate layer occurred in existing aluminium etching antenna card.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technology thereof, then the utility model is also intended to comprise these change and modification.
