Technical field
The utility model belongs to RFID electronic label technology field, and particularly a kind of raising read the conforming RFID anti-metal electronic tag of distance.
Background technology
Along with the development of semiconductor technology, extensive or ultra-large integrated circuit all finds broad application in a lot of fields, this has directly caused the development of chip package process, be characterized in, by etching, the solder joint of the complete wafer stage chip of growth process by manual binding machine welding aluminum steel to antenna substrate, thereby realizing circuit connects, by epoxy resin, wafer stage chip and aluminum steel are encapsulated again, thereby wafer stage chip is applied on concrete circuit substrate, this mode has formed ripe technique, can make the wafer stage chip of small size is directly the use of downstream producer by general welding technology reliably.
Mainly there are the following problems for current technology: aluminum steel of (1) manual binding is difficult to accomplish that length is consistent, different in sizely easily causes resistance and inductance property is inconsistent in batches; (2) encapsulate with resin glue, it is in full accord how many flatness, consumptions are difficult to accomplish, error can cause that the batch of resistance and inductance is inconsistent.As above 2 problems can produce antenna and mate the very large problem of error in batches with the conjugate impedance of chip, and while finally causing whole RFID anti-metal tag batch production, the inconsistent probability of happening of decipherment distance is very big.
Therefore, it is consistent that the batch of a kind of resistance and inductance is badly in need of in RFID electronic label technology field, and error is little in batches for conjugate impedance coupling, and the consistent one of decipherment distance improves and reads the conforming RFID anti-metal electronic tag of distance.
Utility model content
The utility model provides a kind of raising to read the conforming RFID anti-metal electronic tag of distance, and technical scheme is as follows:
A kind of raising read the conforming RFID anti-metal electronic tag of distance, it is characterized in that, comprising: antenna substrate, SMT steel mesh, leg tin cream, blue oil layer, RFID chip;
Antenna substrate, surface has pad, and 2 ends have respectively symmetrical circular hole;
SMT steel mesh, covers on antenna substrate, is connected with antenna substrate, and surface has mesh, the position of mesh and the position consistency of pad;
Leg tin cream, is filled in the mesh of SMT steel mesh;
Blue oil layer, is positioned at antenna substrate surface;
RFID chip, has 3 pins, and 3 pins are between the pad and leg tin cream of antenna substrate.
A kind of raising as above read the conforming RFID anti-metal electronic tag of distance, and wherein, SMT steel mesh is the encapsulating structure of SOT-323 form.
The beneficial effects of the utility model are:
1, the utility model arranges blue oil layer on antenna substrate surface, is different from the structure of exposed Copper Foil in traditional binding technique, because blue oil layer has the effect of welding resistance, is difficult for causing oxidation, and stability is better, has extended serviceable life, cost-saving.
2, the utility model is by behind pad fixed position, and the position of RFID chip is fixed by leg tin cream, therefore limited the structure of RFID chip and the concrete link position of antenna substrate, consistance is splendid.Therefore the pad locations of antenna substrate, the resistance of feed port and the batch of inductance are consistent, and error is little in batches for conjugate impedance coupling, and decipherment distance is consistent.
