Foreword
Saka, zvakakosha kuyeuka kuti mamakisi ekuvhura kwandiri kwaive kuenderera mberi kwechido changu chekushanda neelectron microscopy uye kucheka. kumashure muna 2012. IN Dzidziso yekushanda kwematagi eRFID yakaongororwa muchidimbu, uye akati wandei akajairika uye aripo tags panguva iyoyo akavhurwa uye akaparadzaniswa.
Panogona kunge paine zvishoma zvinogona kuwedzerwa kuchinyorwa ichi nhasi: yakafanana 3(4) yakajairika zviyero LF (120-150 kHz), HF (13.65 MHz - mazhinji ma tag anoshanda mune iyi renji), UHF (chaizvoizvo, kune maviri frequency renji 433 uye 866 MHz), inoteverwa ne ; iwo mamisimboti ekushanda - kupinza magetsi kune chip nemasaisai eredhiyo uye kugadzirisa chiratidzo chinouya nekubuda kweruzivo kudzokera kune anogamuchira.
Kazhinji, tag yeRFID inotaridzika seizvi: substrate, antenna, uye chip pachayo.
Tag-iyo kubva kuTexas Instruments
Nekudaro, iyo "nzvimbo" yekushandisa aya ma tag muhupenyu hwezuva nezuva yachinja zvakanyanya.
Kana muna 2012 NFC () chaiva chinhu chinoshamisa mu smartphone, iyo yakanga isina kujeka kuti ingashandiswa sei uye kupi. Uye hofori dzakadai saSony, semuenzaniso, dzakasimudzira NFC neRFID senzira yekubatanidza zvishandiso (mukurukuri kubva kune yekutanga Sony Xperia, iyo inobatanidza nemashiripiti nekubata foni - Wow! Shock content!) uye kuchinja nyika (somuenzaniso, akauya kumba, akatsvaira pa tag, foni yakashandura inzwi, yakabatana neWiFi, nezvimwewo), iyo, mumaonero angu, yakanga isinganyanyi kufarirwa.
Zvino muna 2019, simbe chete hadzishandise makadhi asina waya (ichiri iyo NFC imwe chete, yakakura), nhare dzine makadhi chaiwo (hanzvadzi yangu, pakuchinja foni yake, yakaramba ichida NFC mairi) uye kumwe "kurerutsa" kwehupenyu hwakavakirwa. pane tekinoroji iyi. RFID yave chikamu chakakosha chehupenyu hwedu hwezuva nezuva: anoraswa mabhazi anopfuura, makadhi ekuwana akawanda mahofisi uye zvimwe zvivakwa, mini-wallet mukati memasangano (akadai se ) "uye zvichingodaro, zvichingodaro, zvichingodaro."
Chaizvoizvo, ichi ndicho chikonzero nei kune nhamba yakakura kudaro yemategi, imwe neimwe yaunoda kuvhura uye kuona iyo yakavanzika mukati: ndiani chip akaiswa? yakachengetedzwa here? rudzii rwe antenna?
Asi zvinhu zvekutanga kutanga ...
Aive aya madiki zvidimbu zvesilicon zvakaita kuti nyika yedu ive nzira yatinoiziva nayo nhasi.
Mazwi mashoma ekuvhura ma tag
Rega ndikuyeuchidze kuti kuti usvike kune chip pachayo, unofanirwa kudzikisa chigadzirwa uchishandisa mamwe makemikari reagents. Semuenzaniso, bvisa goko (kazhinji kadhi kana yepurasitiki tag ine antenna mukati), nyatso bvisa chip kubva muantenna, geza chip yacho pachayo kubva glue / insulator, dzimwe nguva bvisa zvikamu zve antenna zvakasungwa zvakasimba kune ekubata pads. , uye chete wozoona chip uye marongero ayo.
Deprocessing kunzwa kwakaoma
Zvishandiso zvinoshandiswa kukwirisa machipisi zvakaita kuvandudzwa kunoshamisa mumakore achangopfuura. Kune rumwe rutivi, izvi zvakawedzera kuvimbika kwechip attachment uye kuderedza nhamba yezvikanganiso; nerumwe rutivi, kungofashaira muacetone kana kuti concentrated sulfuric acid kunyungudutsa kana kupisa organic matter zvino hazvichageze chip. Iwe unofanirwa kuwana yakanyanyisa, sarudza musanganiswa weasidhi kuitira kuti ubvise zvisingakoshi zvidimbu, asi panguva imwechete usakuvadza motori wemoto kune metallization yechip.
Matambudziko ekudzikisa: kana glue kubva pachipu haigoni kushambidzwa pasi pemamiriro ezvinhu ... Pano uye mberi LM - laser microscopy, OM -Optical microscopy
Kana kuti...
Dzimwe nguva, hongu, iwe une rombo rakanaka uye chip, kunyangwe ine insulating layer, inoshanduka kuve yakachena, iyo isinganyanye kukanganisa kunaka kwemufananidzo:
