Cyclone® Family FPGAs

Intel Cyclone® Family FPGAs amamangidwa kuti akwaniritse zosowa zanu zamapangidwe otsika, osakwera mtengo, kukuthandizani kuti mufike pamsika mwachangu.M'badwo uliwonse wa Cyclone FPGAs umathetsa zovuta zaukadaulo pakuphatikizana kowonjezereka, kuchuluka kwa magwiridwe antchito, mphamvu zotsika, komanso nthawi yachangu yogulitsa ndikukwaniritsa zofunikira zotsika mtengo.Intel Cyclone V FPGAs imapereka mtengo wotsika kwambiri pamsika komanso mphamvu yotsika kwambiri ya FPGA yothetsera ntchito m'misika yamakampani, opanda zingwe, mawayilesi, kuwulutsa, ndi ogula.Banja limaphatikiza midadada yochulukirapo (IP) kuti muthe kuchita zambiri ndi mtengo wotsika wadongosolo lonse komanso nthawi yopangira.Ma SoC FPGA m'banja la Cyclone V amapereka zatsopano monga hard processor system (HPS) yokhazikika mozungulira purosesa ya ARM® Cortex™-A9 MPCore ™ yokhala ndi zotumphukira zolimba zochepetsera mphamvu zamakina, mtengo wamakina, ndi kukula kwa board.Intel Cyclone IV FPGAs ndi otsika mtengo kwambiri, otsika mphamvu FPGAs, tsopano ndi transceiver zosiyanasiyana.Banja la Cyclone IV FPGA limayang'ana ma voliyumu apamwamba, osavuta kugwiritsa ntchito, kukuthandizani kukwaniritsa zofunikira za bandwidth pomwe mukutsitsa mtengo.Intel Cyclone III FPGAs imapereka kuphatikiza komwe sikunachitikepo mtengo wotsika, magwiridwe antchito apamwamba, komanso kukhathamiritsa kwamphamvu kuti mukulitse mpikisano wanu.Banja la Cyclone III FPGA limapangidwa pogwiritsa ntchito ukadaulo wamagetsi otsika a Taiwan Semiconductor Manufacturing Company kuti apereke kugwiritsa ntchito mphamvu pang'ono pamtengo womwe umafanana ndi ma ASIC.Intel Cyclone II FPGAs amamangidwa kuchokera pansi pamtengo wotsika komanso kuti apereke mawonekedwe odziwika ndi makasitomala omwe amakhazikitsidwa kuti agwiritse ntchito voliyumu yayikulu, yotsika mtengo.Intel Cyclone II FPGAs imapereka magwiridwe antchito apamwamba komanso kugwiritsa ntchito mphamvu zochepa pamtengo womwe umafanana ndi ma ASIC.

Kodi SMT ndi chiyani?

Zamagetsi zambiri zamalonda ndizokhudza ma circuitry ovuta kulowa m'malo ang'onoang'ono.Kuti izi zitheke, zigawozi ziyenera kuyikidwa mwachindunji pa bolodi la dera osati mawaya.Izi ndizomwe teknoloji yokwera pamwamba ili.

Kodi Surface Mount Technology ndiyofunikira?

Zamagetsi zambiri zamakono zimapangidwa ndi SMT, kapena ukadaulo wapamtunda.Zipangizo ndi zinthu zomwe zimagwiritsa ntchito SMT zimakhala ndi maubwino ambiri kuposa mabwalo omwe amayendetsedwa kale;zipangizo zimenezi zimadziwika kuti SMDs, kapena pamwamba phiri zipangizo.Ubwinowu watsimikizira kuti SMT yalamulira dziko la PCB kuyambira pomwe idakhazikitsidwa.

Ubwino wa SMT

• Ubwino waukulu wa SMT ndikuloleza kupanga ndi kuwotcha.Izi ndizotsika mtengo komanso zopulumutsa nthawi komanso zimalola kuti pakhale dera lokhazikika.Kusungirako ndalama zopangira zinthu nthawi zambiri kumaperekedwa kwa kasitomala - kuzipangitsa kukhala zopindulitsa kwa aliyense.
• Mabowo ochepera amafunikira kubowola pama board ozungulira
• Mtengo wake ndi wotsika kuposa magawo ofanana ndi bowo
• Mbali iliyonse ya bolodi yozungulira ikhoza kukhala ndi zigawo zake
• Zida za SMT ndizochepa kwambiri
• Kachulukidwe kagawo kakang'ono
• Kuchita bwino pansi pa kugwedezeka ndi kugwedezeka.

Zoyipa za SMT

• Ziwalo zazikulu kapena zamphamvu kwambiri ndizosayenera pokhapokha pomanga pobowo akugwiritsidwa ntchito.
• Kukonza pamanja kungakhale kovuta kwambiri chifukwa cha kuchepa kwambiri kwa zigawo.
• SMT ikhoza kukhala yosayenera pazigawo zomwe zimalandira kulumikizidwa pafupipafupi ndikudula.

Kodi zida za SMT ndi chiyani?

Zida zokwera pamwamba kapena ma SMD ndi zida zomwe zimagwiritsa ntchito ukadaulo wapamwamba kwambiri.Zigawo zosiyanasiyana zomwe zimagwiritsidwa ntchito zimapangidwira kuti zigulitsidwe mwachindunji ku bolodi m'malo momangirira mawaya pakati pa mfundo ziwiri, monga momwe zimakhalira ndi luso lamakono.Pali magulu atatu akuluakulu a zigawo za SMT.

Ma SMD osavuta

Ambiri mwa ma SMD omwe amangokhala ndi ma resistors kapena capacitors.Makulidwe a phukusi la izi ndi okhazikika bwino, zigawo zina kuphatikiza ma coils, makhiristo ndi zina zimakhala ndi zofunikira zenizeni.

Maulendo ophatikizika

Zazambiri za mabwalo ophatikizika ambiri, werengani blog yathu.Mogwirizana ndi SMD makamaka, amatha kusiyanasiyana kutengera kulumikizana komwe kumafunikira.

Transistors ndi diode

Transistors ndi ma diode nthawi zambiri amapezeka mu phukusi la pulasitiki laling'ono.Zotsogolera zimapanga maulumikizano ndikukhudza bolodi.Mapaketi awa amagwiritsa ntchito njira zitatu.

Mbiri yachidule ya SMT

Ukadaulo wa Surface Mount unayamba kugwiritsidwa ntchito kwambiri m'ma 1980, ndipo kutchuka kwake kwangokulirakulira kuchokera pamenepo.Opanga PCB anazindikira mwamsanga kuti zipangizo za SMT zinali zopambana kwambiri kupanga kusiyana ndi njira zomwe zilipo kale.SMT imalola kuti kupanga kukhale kwamakina ambiri.M'mbuyomu, ma PCB adagwiritsa ntchito mawaya kulumikiza zida zawo.Mawayawa ankayendetsedwa ndi manja pogwiritsa ntchito njira yodutsa pobowo.Mabowo omwe anali pamwamba pa bolodi anali ndi mawaya odutsamo, ndipo izi, nazonso, zimagwirizanitsa zigawo zamagetsi.Ma PCB achikhalidwe amafunikira anthu kuti athandizire kupanga izi.SMT idachotsa gawo lovutali pantchitoyi.Zida m'malo mwake zidagulitsidwa pamapadi pamatabwa m'malo mwake - chifukwa chake 'kukweza pamwamba'.

SMT ikugwira ntchito

Momwe SMT idadzipangira makina amatanthawuza kuti kugwiritsidwa ntchito kufalikira mwachangu m'makampani onse.Zigawo zatsopano zatsopano zidapangidwa kuti zizitsagana ndi izi.Izi nthawi zambiri zimakhala zazing'ono kuposa zomwe zimadutsa m'mabowo.Ma SMD adatha kukhala ndi ma pini apamwamba kwambiri.Nthawi zambiri, ma SMTs nawonso amakhala ophatikizika kwambiri kuposa ma board ozungulira mabowo, zomwe zimapangitsa kuti pakhale ndalama zotsika.Ponseponse, zidazi ndizosavuta komanso zotsika mtengo.Amatha kupita patsogolo kwaukadaulo komwe sikukadatha kuganiza pogwiritsa ntchito dzenje.

Ikugwiritsidwa ntchito mu 2017

Msonkhano wa Surface Mount uli pafupifupi ulamuliro wonse pakupanga PCB.Sikuti ndizongopanga zokhazokha, komanso zazing'ono zonyamula, koma zida zazing'onozi zimagwiranso ntchito kwambiri.Ndizosavuta kuwona chifukwa chake kupanga kwa PCB kwasuntha kuchokera panjira yamawaya kudzera pamabowo.
