Indlela yokukhetha aisinxibelelanisi?Kukho iintlobo ezininzi zezixhumanisi.Iindidi eziqhelekileyo ziquka iitheminali zonxibelelwano lonxibelelwano.Iibhloko zetheminali.Izixhumi zocingo ukuya ebhodini.Izixhumi zebhodi ukuya kwibhodi.Uhlobo ngalunye lunokwahlulwa lube ngamacandelo amaninzi, umzekelo, izixhumi zebhodi ukuya kwibhodi ziquka iintloko zepini kunye neebhasi..Iziqhagamshelo zeBhodi ukuya kwiBhodi, njl.Izixhumi zocingo ukuya ebhodini ziquka izihlanganisi zeFPC.I-IDC iziseko zamandla.Iimpondo zenyathi ezilula, njl.njl. Kwinkqubo yokukhetha isinxibelelanisi, yeyiphi imbono ekufuneka siyithathele ingqalelo isinxibelelanisi ekufuneka sisetyenziswe kuqwalaselo lwehardware efanelekileyo?1. Iphini.Isithuba Inani lezikhonkwane.Isithuba sephini sisisiseko esiphambili sokukhetha imodeli yesinxibelelanisi.Inani lezikhonkwane ezikhethiweyo lixhomekeke kwisixa esipheleleyo solwazi ekufuneka lufikelelwe.Kwezinye izihlanganisi zepatch, njengoko kubonisiwe kumzobo ongezantsi, inani leepatshi alikwazi ukuba likhulu kakhulu.Ngethuba lenkqubo ye-welding yomatshini wokubeka, ngenxa yefuthe eliqhubekayo lobushushu obuphezulu, iplastiki yesiqhagamshelo iya kuphuma phakathi xa i-thermal deformed, okubangelwa ukuwelda okungenanto kwezikhonkwane.Kwinqanaba lokuqala lophuhliso lwe-P800Flash, umdwelisi wenkqubo we-microcontroller wasebenzisa le ntloko ye-pin.Ibhodi yomama idibaniswe omnye komnye, kwaye kwagqitywa ukuba isampuli ye-pin header yathengiswa kwizinga elikhulu.Emva kokutshintsha iiheader ezimbini zepin ngezibalo ezincitshisiweyo zepin, akusekho solder engenanto.Ngoku iimveliso ze-elektroniki ziphuhlisa kwicala le-miniaturization.Ngomkhwa wophuhliso wokuchaneka, i-pin pitch yezihlanganisi nayo iqala ukusuka kwi-2.54mm ukuya kwi-1.27mm kwaye emva koko ukuya kwi-0.5mm.Okukhona sincinci isithuba sephini, kokukhona ziphezulu iimfuno zeteknoloji yokusetyenzwa.Inqanaba leteknoloji yokuvelisa ixhomekeke ekulandeleni ngokungaboniyo umkhwa kunye nokulandela umgama omncinci ogqibeleleyo 2. Iimpawu zezixhobo zombane Iimpawu zezixhobo zombane zekhonkco zibandakanya ngokukodwa: ukukhawulela okwangoku, ukuchasana kwe-loop, ukuxhathisa umhlaba kunye namandla oxinzelelo.Xa udibanisa i-resistors-power high-power, nikela ingqalelo kumda wokukhawulela umdibaniso;xa uhambisa iimpawu ze-high-frequency signals, ezifana ne-high-frequency signals, njenge-LVDS.PCIe elinde iimpawu, qaphela ukuchasana kwesiphaluka.Isidibanisi kufuneka sibe noxhathiso oluphantsi noluzinzileyo lwesekethe, ngokubanzi amashumi e-mΩ ukuya kumakhulu e-mΩ.3. Iimpawu zokusingqongileyo zendalo Iimpawu zendalo zendalo yesiqhagamshelo zibandakanya ikakhulu: ukumelana nobushushu obuphezulu, ukuxhathisa ukufuma, ukuxhathisa ityuwa yokutshiza, ukungcangcazela, ukothuka, njl. Khetha ngokwemeko yokwenyani yesicelo.Ukuba indawo yesicelo imanzi kwaye ibanda, ukuxhathisa ukufuma kwekhonkco.Ukumelana nokutshizwa kwetyuwa kuchazwe kakhulu ukuthintela iindawo zoqhagamshelwano zentsimbi yesiqhagamshelo ekuruseni.Kwi-automation ye-industrial, ukusebenza kwempembelelo yesiqhagamshelo kufuneka ibe phezulu ukukhusela umdibaniso ukuba ungawa phantsi kweemeko zokungcangcazela.4. Iimpawu ezibonakalayo Iipropati ezibonakalayo zekhonkco zibandakanya amandla okufaka, izixhobo zomatshini zobungqina bephutha, njl. Kwiziqhagamshelo, ukuqinisekiswa kwephutha kwisixhobo somatshini kubaluleke kakhulu.Nje ukuba ifakwe umva, inokubangela umonakalo ongenakuguqulwa kwisekethe!Amandla okufaka ahlulahlulwa abe ngamandla okufaka kunye nokwahlula.Imigangatho efanelekileyo ibandakanya amandla amakhulu okufaka kunye namandla okwahlukana aphantsi.Ukusuka kwindawo yokujonga isicelo, amandla okufaka kufuneka abe yincinci kwaye amandla okuhlula kufuneka abe phezulu.Ifutshane kakhulu amandla okwahlukana aya kunciphisa ukuzinza koqhagamshelwano, kodwa kwiikhonkco ezimele zifakwe rhoqo, ukutshintshiselwa kwamandla okuhlukana kuya kwandisa ubunzima kunye nokunciphisa ubomi benkonzo yezixhobo zoomatshini.Ukuze kuncitshiswe amandla okuhlukana kwekhonkco kwaye kube lula kubathengi ukuba bafake iibhodi ezihambelanayo, senze iinzame ezininzi, kwaye ekugqibeleni safumana ukukhanya kwindlela yokuhlola, kwaye ekugqibeleni sisebenzisa isinxibelelanisi esiboniswe kumzobo ongezantsi. kwaye yatshintsha iPCB kunye nolwakhiwo lwetyala lemveliso.Ngokukodwa, esi sidibanisi sinobungqina obukhethekileyo, umphumo ocacileyo wobungqina bempazamo, amandla aphantsi okufakwayo, amandla okuhlula okuphakathi, kunye nemvakalelo emihle yesandla xa ifakiwe, ephucula kakhulu ukusetyenziswa kwesicelo sokufaka.Izixhumi, i-alias connectors yeenjineli zobugcisa, zisetyenziselwa ukudibanisa iibhodi zeesekethe ezimbini okanye iimveliso zombane ukugqiba ukuhanjiswa kwamandla okutshintsha okanye ulwazi.Ngokuhambelana nekhonkco, idizayini yemodyuli yesekethe yamandla inokwenziwa, yonke inkqubo yenkqubo yendibano yezixhobo zombane inokwenziwa lula, kwaye iimpahla zinokuququzelelwa ukugcinwa nokuhlaziywa.Kwiisekethe zamandla eziyilwe ngokwemodyuli, ukhetho lohlobo lwesihlanganisi ludlala indima ebalulekileyo.
