Abstract
The invention provides a small-size electronic tag antenna and a manufacture method thereof. The method comprises the following steps: printing a first printed coil on a substrate by using electrically conductive ink, and covering an insulating layer on the first printed coil; printing a second printed coil positioned at the upper surface of the insulating layer and a pair of terminals which are used for connecting an IC chip and positioned at the middle part of the substrate by using the electrically conductive ink, and enabling the initial end of the second printed coil to be connected with the tail end of the first printed coil, and enabling the tail end of the second printed coil and the initial end of the first printed coil respectively to be connected with the pair of terminals. The invention adopts a plurality of printed coils connected in series to be stacked on the substrate, and the antenna is manufactured between layers by using an isolation mode, so that the automatic production is easily realized, and the production cost is low. The antenna and the tag have small volumes, and are used conveniently; the printed coils of the antenna are stacked on the easily-broken substrate; when the substrate is damaged, the coil and the circuits are damaged together, so that the anti-fake tags can be avoided being possibly reused without permission, and the invention is safe and has good secrecy.
Description
Technical field
The invention belongs to the manufacture method of anti-counterfeiting electronic tag technical field, particularly a kind of small-size electronic tag antenna, and small-size electronic tag antenna and the small-size electronic tag made by the method.
Background technology
Electronic tag is used widely in the false proof field of electronic article, but along with commodity constantly develop to small-sized, microminiaturized, in a lot of use occasions, require the size of electronic tag more and more less, to satisfy the demand that makes things convenient for pasting electronic label on any commodity and any position on any commodity.
At present, electronic tag adopts wire winding, etch process and three kinds of manufacturing process of typography to produce more.Front two sides kind technique is difficult to realize false proof desired tamper function, owing to electronic tag itself can be reused, thereby loses false proof ability.In addition, the electronic label antenna that these two kinds of techniques are produced and the price of label product are very expensive, thereby have limited its extensive use.
Consider that from tamper performance and cost aspect above-mentioned typography is to make the ideal chose of false proof and low-cost electronic antenna and label.As, the disclosed scheme of Chinese patent " non-contact electronic anti-false identification label " (patent No. ZL99110297.5), its wire loop or a part of circuit wherein are to be that the substrate printing of base material forms by electrically conductive ink in fragile paper, and the two ends of the coil circuit on above-mentioned fragile paper substrate connect one to have specific cryptographic algorithm and have the IC integrated circuit of specific cryptosystem.This anti-fake label forms coil by mode of printing at paper substrate, and coil is together damaged when paper substrates is damaged, and makes anti-counterfeiting label avoid possible reusing.
But usually adopt the fertile electronic label antenna of existing typography, its live width minimum is about 0.3mm, the wire spacing minimum is 0.3mm, if surpass this live width and distance between centers of tracks lower range, typography is difficult to realize, and percent defective is very high, thereby manufacturing cost is greatly increased, and has therefore lost practicality.As, press 0.3mm live width, 0.3mm wire spacing, the minimum feature size of the electronic tag that satisfies iso standard 13.56MHz centre frequency by the typography manufacturing is 40mm, when label sizes is further dwindled, owing to do not have the antenna of enough enough number of turns of space arrangement, thereby it is many to make frequency tend to exceed our desired scope (being centre frequency 13.56MHz).
Summary of the invention
The defects that exists for overcoming existing Anti-fake electronic label antenna manufacturing technology the invention provides a kind of manufacture method of small-size electronic tag antenna, and small-size electronic tag antenna and the small-size electronic tag made by the method.The present invention adopts printed coil stacked setting on substrate of a plurality of series connection, and make the small size label antenna in the zone isolation mode, be convenient to realize automated production, production cost is low, the antenna that it is made and label volume are little, easy to use, can satisfy ideally the market demand of small size Anti-fake electronic label.
Small-size electronic tag antenna manufacture method of the present invention may further comprise the steps:
Wherein, described substrate is the scraps of paper or mylar etc.
The width of the line of described first, second printed coil is 0.2-0.7mm, and wire spacing is 0.3-1.0mm; The thickness of described insulating barrier is 4-35 μ m.
Described insulating barrier is annular, and its outer edge is provided with notch part, the top of described the second printed coil be connected the end of printed coil and in described notch part, connect by printing.
The helix of described the second printed coil can be positioned at the top, gap of the helix of the first printed coil below the insulating barrier, to reduce the distributed capacitance between two printed coils.
