Description
Technical field
The present invention relates to a kind of electronic tag and adopt the printed circuit board of this label, relate in particular to a kind of split type passive electronic label and adopt the printed circuit board of this label.
Background technology
In the big events such as Aero-Space, to product designation and the independent assembly of paying are arranged, other product of equipment (containing) higher level, the product quality form of personal details is set up in requirement, product log should be set up when Product Assembly begins, main record product is paid the quality and performance situation before dispatching from the factory, the quality problems that occur behind the product export, every content in the product log should have trackability, product log is standby by the production unit responsibility system, fill in, preserve, file, guarantee in time to provide inquiry and use, and be responsible for providing copy by the requirement of general assembly unit.Every content in the product log should be in time, fill in exactly, and in accordance with regulations signature.The employing of product log, to the supervision of batch changing management, product quality of product with review the very important effect of having played.
The product quality form of personal details of at present aerospace field product employing all is the papery form of personal details basically, be that production unit prepares different paper products forms of personal details according to code requirement in advance to different product, be responsible at the scene record by technological process by the special messenger, input again computing machine and preserve, print paper-copy when needing and hand over general assembly unit.There is following shortcoming in existing record management method: (1) papery is filled in, and different product requires different table content, and preparation papery form of personal details increases cost, loses time; (2) the on-the-spot hand filling of papery form of personal details, standardization control is difficult, exists easily fill substance unclear; (3) the on-the-spot keeping of paper document is inconvenient, also needs again input computer afterwards, increases work load, and promptness is inadequate; (4) paper document inquiry and use very inconveniently, the papery form of personal details is difficult to surely with corresponding nation in kind simultaneously, and paper document is corresponding with printed circuit board to be the comparatively difficult thing of part; (5) after papery form of personal details copy was transferred to general assembly unit, applying unit was difficult to carry out timely and effectively quality analysis; (6) papery form of personal details content be difficult in time to have access to, the Authorized operation management of classification inquiry, additional modifications etc., it is very large constant to bring for outfield user debugging and quality check.
Along with the develop rapidly of electronic information technology, papery form of personal details electronization is the inexorable trend of development, how the electronic record book is used for printed circuit board, and the scheme that can select at present has SD card, contact SIM card, passive RFID tags.These electronic products have relatively large memory capacity, but SD card and contact SIM card connecting line is more, cost is high, processing is used complicatedly is embedded in that to use on the printed circuit board be not very suitable.
RFID is a kind of simple wireless system, is comprised of an interrogator (or reader) and a lot of transponder (or label).The RF technology utilizes wireless radio frequency mode to carry out the noncontact bi-directional transfer of data between reader and radio-frequency card, to reach the purpose of target identification and exchanges data.1), label (Tag, i.e. radio-frequency card) the most basic RF system is comprised of three parts:: be comprised of coupling element and chip, label contains built-in aerial, be used for and radio-frequency antenna between communicate.2), reader: the equipment that reads (in read-write card, can also write) label information; 3), radio-frequency antenna: between label and reader, transmit radiofrequency signal.
The RFID label is commonly called as electronic tag, also claim transponder (tag, transponder, responder), can be divided into active (active) and passive type (passive) two large classes according to working method, passive type RFID label is comprised of label chip and label antenna or coil, utilize inductive coupling or electromagnetic backscatter coupling principle realize and read write line between communication.Unique coding of storage is generally 64bits, 96bits even higher in the RFID label, and its address space is much higher than the space that bar code can provide, and therefore can realize the article code of single grade.Enter the zone of action of read write line when the RFID label, just can produce the induced electricity potential difference at the label antenna two ends according to inductive coupling principle (in the reach of near field) or electromagnetic backscatter coupling principle (in the reach of far field), and in the label chip path, form weak current, if this strength of current surpasses a threshold value, just will activate RFID label chip circuit working, thereby the storer in the label chip is carried out read/write operation, microcontroller can also further add sophisticated functionss such as password or anti-collision algorithm, very is suitable for making the printed circuit board electron form of personal details.
The RFID label that is applied at present article supervision field substantially all is the passive soft label of RFID, the soft label of RFID is printed on the metal induction antenna on the soft materials such as paper, PVC film exactly, IC chip flip chip package forms the RFID label at induction antenna, again the soft label of RFID is coated with and is covered with gum, can directly glue when specifically using and be posted on the article.
With the soft label of the RFID of gum, its advantage is not need printed circuit board to anticipate, and directly pastes at printed circuit board and uses.The shortcoming that exists is: will increase the space of certain area on (1) printed circuit board for the soft label sticking of RFID, be difficult to satisfy for small-sized or special-shaped printed circuit board; (2) RFID soft label by glue on printed circuit board, be not easy to printed circuit board and stand the cleaning of solvent, simultaneously when printed circuit board environmental test and use, because the factor of environmental stress causes the soft label of RFID to come off easily or label chip is connected the problems such as not smooth with induction antenna; (3) the soft label induction antenna of RFID is electric conductor, in case damage or the meeting that comes off produce electric fifth wheel; (4) electric parameter of the soft label of RFID is subject to the impact of printed circuit board surrounding enviroment easily; (5) the soft label induction antenna of RFID itself is exactly that a telefault exists the electric parameter to printed circuit board itself to exert an influence sometimes.
If the passive RFID tags induction antenna is directly designed on printed circuit board, has equally following point: will increase larger space on (1) printed circuit board and lay for RFID label induction antenna, be difficult to satisfy for small-sized or special-shaped printed circuit board; (2) RFID label induction antenna be designed with professional electric parameter requirement, and the media environment of the shape of induction antenna and attached work all can be relevant, this increase a lot of work difficulty will for the Printed Circuit Board Design personnel; (3) design of RFID label induction antenna exists the electric parameter to printed circuit board itself to exert an influence on printed circuit board sometimes; (4) the RFID label induction antenna of design on printed circuit board is various, does not utilize standardization to use.Therefore the printed circuit board that is necessary to provide split type passive electronic label and adopts this label is avoided induction antenna to take installing space and is reached the shortcoming that easily causes interference.
