Ibidukikije & Kohereza ibicuruzwa mu byiciro

Altera Cyclone® IV FPGAs yongerera ubuyobozi bwa serivise ya Cyclone FPGA mugutanga igiciro gito cyisoko, ingufu nkeya FPGAs, ubu hamwe na transceiver variant.Ibikoresho bya Cyclone IV bigenewe amajwi menshi, porogaramu-yorohereza porogaramu, ituma abashushanya sisitemu yujuje ibyifuzo byiyongera mugihe bagabanya ibiciro.Gutanga ingufu nigiciro cyo kuzigama utitanze kubikorwa, hamwe nigiciro gito cyo guhuza transceiver ihendutse, ibikoresho bya Cyclone IV nibyiza kubiciro bidahenze, bito-bito-bito bikoreshwa muburyo butagikoreshwa, insinga, insinga, itumanaho, inganda, abaguzi, n’itumanaho. .Yubatswe kumurongo wogukoresha imbaraga nkeya, umuryango wibikoresho bya Altera Cyclone IV utanga ibintu bibiri.Cyclone IV E itanga imbaraga zo hasi nibikorwa byinshi hamwe nigiciro gito.Cyclone IV GX itanga imbaraga nkeya nigiciro gito FPGAs hamwe na 3.125Gbps transceiver.

Cyclone® Umuryango FPGAs

Intel Cyclone® Family FPGAs yubatswe kugirango ihuze imbaraga zawe nke, zita kubiciro bikenewe, bigufasha kugera kumasoko byihuse.Buri gisekuru cya Cyclone FPGAs gikemura ibibazo bya tekiniki yo kongera kwishyira hamwe, kongera imikorere, imbaraga nke, nigihe cyihuse cyo kwisoko mugihe byujuje ibyangombwa bisabwa.Intel Cyclone V FPGAs itanga isoko rya sisitemu yo hasi cyane hamwe nimbaraga nke FPGA igisubizo kubisabwa mu nganda, insinga, insinga, itumanaho, n’isoko ry’abaguzi.Umuryango uhuza ibintu byinshi byumutungo wubwenge (IP) kugirango ubashe gukora byinshi hamwe nigiciro gito cya sisitemu nigihe cyo gushushanya.SoC FPGAs mumuryango wa Cyclone V itanga udushya twihariye nka sisitemu ikomeye itunganya ibintu (HPS) ishingiye kumurongo wa ARM® Cortex ™ -A9 MPCore ™ itunganya ibintu byinshi hamwe na periferi zikomeye kugirango igabanye ingufu za sisitemu, igiciro cya sisitemu, n'ubunini bw'inama.Intel Cyclone IV FPGAs nigiciro gito, imbaraga nkeya FPGAs, ubu hamwe na transceiver variant.Umuryango wa Cyclone IV FPGA wibasiye ubwinshi, porogaramu zita ku biciro, bigufasha kuzuza ibisabwa byiyongera mugihe ugabanya ibiciro.Intel Cyclone III FPGAs itanga ihuriro ritigeze ribaho ryigiciro gito, imikorere ihanitse, hamwe nogutezimbere imbaraga kugirango urusheho gutsinda.Umuryango wa Cyclone III FPGA wakozwe hifashishijwe tekinoroji yo muri Tayiwani Semiconductor Manufacturing Company ikoresha ingufu nkeya kugirango itange ingufu nke ku giciro gihanganye n’icya ASIC.Intel Cyclone II FPGAs yubatswe kuva hasi kugeza ku giciro gito no gutanga ibiranga umukiriya washyizweho kubijwi ryinshi, byorohereza porogaramu.Intel Cyclone II FPGAs itanga imikorere ihanitse kandi ikoresha ingufu nke kubiciro bihanganye nibya ASIC.

SMT ni iki?

Umubare munini wibikoresho bya elegitoroniki byubucuruzi byose byerekeranye numuzunguruko uhuza umwanya muto.Kugirango ukore ibi, ibice bigomba gushyirwaho muburyo butaziguye aho kuba insinga.Nibyingenzi mubyukuri tekinoroji yo hejuru.

Ikoranabuhanga rya Surface Mount ni ngombwa?

Umubare munini wibikoresho bya elegitoroniki byubu byakozwe na SMT, cyangwa tekinoroji yo hejuru.Ibikoresho nibicuruzwa bikoresha SMT bifite umubare munini wibyiza kurenza imirongo isanzwe ikoreshwa;ibyo bikoresho bizwi nka SMDs, cyangwa ibikoresho byo hejuru.Izi nyungu zemeje ko SMT yiganjemo isi ya PCB kuva yashingwa.

Ibyiza bya SMT

• Inyungu nyamukuru ya SMT nukwemerera umusaruro wikora no kugurisha.Ibi nibiciro kandi bizigama umwanya kandi binemerera kumurongo uhoraho.Kuzigama mubiciro byo gukora akenshi bishyikirizwa abakiriya - bigatuma bigirira akamaro buri wese.
• Umwobo muto ugomba gucukurwa ku mbaho ​​zumuzunguruko
• Ibiciro biri munsi ugereranije nu mwobo uhwanye
• Impande zombi zumuzunguruko zishobora kugira ibice byashyizwemo
• Ibice bya SMT ni bito cyane
• Ubucucike buri hejuru
• Imikorere myiza mugihe cyo kunyeganyega no kunyeganyega.

Ibibi bya SMT

• Ibice binini cyangwa imbaraga-nyinshi ntibikwiye keretse iyo hakoreshejwe umwobo.
• Gusana intoki birashobora kugorana cyane kubera ubunini buke bwibigize.
• SMT irashobora kuba idakwiriye kubice byakira kenshi guhuza no guhagarika.

Ni ibihe bikoresho bya SMT?

Ibikoresho byo hejuru yububiko cyangwa SMDs nibikoresho bikoresha tekinoroji yo hejuru.Ibice bitandukanye bikoreshwa byateguwe kugirango bigurishwe ku kibaho aho kuba insinga hagati yingingo ebyiri, nkuko bigenda hifashishijwe ikoranabuhanga.Hariho ibyiciro bitatu byingenzi bigize SMT.

SMDs

Ubwinshi bwa SMDs passive ni résistoriste cyangwa capacator.Ingano ya paki kuri izi zisanzwe neza, ibindi bice birimo coil, kristu nibindi bikunda kugira ibisabwa byihariye.

Inzira zuzuye

Kuriandi makuru yerekeye imiyoboro ihuriweho muri rusange, soma blog yacu.Kubijyanye na SMD byumwihariko, birashobora gutandukana cyane bitewe numuyoboro ukenewe.

Transistors na diode

Transistors na diode bikunze kuboneka mugikoresho gito cya plastiki.Kuyobora gushiraho amahuza no gukora ku kibaho.Ipaki zikoresha inzira eshatu.

Amateka magufi ya SMT

Tekinoroji ya Surface yakoreshejwe cyane mu myaka ya za 1980, kandi gukundwa kwayo kwiyongereye kuva aho.Abakora PCB bahise bamenya ko ibikoresho bya SMT byari byiza cyane kubyara umusaruro kuruta uburyo buriho.SMT yemerera umusaruro gukoreshwa cyane.Mbere, PCBs yakoreshaga insinga kugirango zihuze ibice byazo.Izi nsinga zacishijwe intoki hakoreshejwe uburyo bwo guca umwobo.Imyobo hejuru yikibaho yari ifite insinga zinyuzemo, kandi nazo, zahuzaga ibikoresho bya elegitoroniki hamwe.PCB gakondo yari ikeneye abantu kugirango bafashe muruganda.SMT yakuyeho iyi ntambwe itoroshye mubikorwa.Ibigize ahubwo byagurishijwe ku mbaho ​​ku mbaho ​​aho - bityo 'hejuru yubuso'.

SMT ifata

Uburyo SMT yihaye imashini bivuze ko imikoreshereze yakwirakwiriye vuba mu nganda.Hashyizweho ibice bishya bigize ibice kugirango biherekeze ibi.Ibi akenshi usanga ari bito ugereranije na bagenzi babo.SMDs zashoboye kugira ibara ryinshi cyane.Muri rusange, SMTs nayo iroroshye cyane kuruta ikibaho cyumuzunguruko, bigatuma ibiciro byubwikorezi bigabanuka.Muri rusange, ibikoresho birakorwa neza cyane kandi byubukungu.Bashoboye iterambere ryikoranabuhanga ridashobora gutekerezwa ukoresheje umwobo.

Gukoreshwa muri 2017

Iteraniro rya Surface rifite hafi yiganjemo gahunda yo kurema PCB.Ntabwo aribyiza gusa kubyara umusaruro, kandi bito byo gutwara, ariko ibyo bikoresho bito nabyo birakora neza.Biroroshye kubona impamvu umusaruro wa PCB wimutse uva muburyo bwakoreshejwe.
