Indlela yokukhetha aisixhumi?Kunezinhlobo eziningi zezixhumi.Izigaba ezijwayelekile zihlanganisa amatheminali okuxhumana.Amabhulokhi wetheminali.Izixhumi ze-wire-to-board.Izixhumi zebhodi kuya ebhodini.Uhlobo ngalunye lungahlukaniswa ngezigaba eziningana, isibonelo, izixhumi zebhodi ukuya ebhodini zihlanganisa izihloko zephini kanye namabhasi..Izixhumi zebhodi ukuya ebhodini, njll.;Izixhumi ze-wire-to-board zihlanganisa izixhumi ze-FPC.Amasokhethi kagesi e-IDC.Izimpondo zenyathi ezilula, njll. Enqubweni yokukhetha isixhumi, yimuphi umbono okufanele sicabangele isixhumi okufanele sisetshenziswe ekucushweni kwehadiwe efanele?1. Iphinikhodi.Isikhala Inombolo yezikhonkwane.Isikhala sephinikhodi siyisisekelo esiyinhloko sokukhetha imodeli yesixhumi.Inani lamaphinikhodi akhethiwe lincike enanini eliphelele lolwazi okufanele lufinyelelwe.Kwezinye izixhumi ze-patch, njengoba kukhonjisiwe esithombeni esingezansi, inani lama-patches alikwazi ukuba likhulu kakhulu.Phakathi nenqubo yokushisela yomshini wokubeka, ngenxa yomphumela wokushisa ophakeme oqhubekayo, ipulasitiki yesixhumi izophuma phakathi lapho ikhubazekile ngokushisa okushisayo, okuholela ekushiseleni okungenalutho kwezikhonkwane.Esigabeni sokuqala sokuthuthukiswa kwe-P800Flash, umhleli we-microcontroller wasebenzisa lesi sihloko sephini.Ibhodi lomama lalixhunywe komunye nomunye, futhi kwaphetha ngokuthi isihloko sephinikhodi yesampula sathengiswa ngesilinganiso esikhulu.Ngemva kokufaka izihloko zamaphinikhodi amabili ngezibalo ezincishisiwe zamaphini, akusekho ukusoda okungenalutho.Manje imikhiqizo ye-elekthronikhi iyathuthuka ibheke kwi-miniaturization.Ngomkhuba wokuthuthuka wokunemba, iphinikhodi yezixhumi nayo iqala ukusuka ku-2.54mm iye ku-1.27mm bese iye ku-0.5mm.Uma isikhala sephini sincane, ziphezulu izidingo zobuchwepheshe bokucubungula.Izinga lobuchwepheshe bokukhiqiza lincike ekulandeleni ngobumpumputhe ukuthambekela nokuphishekela ibanga elincane eliphelele 2. Izimpawu zempahla kagesi Izici zemishini kagesi yesixhumi ikakhulukazi zihlanganisa: ukukhawula okwamanje, ukumelana ne-loop, ukumelana nomhlaba kanye namandla okucindezela.Uma uxhuma ama-resistors anamandla amakhulu, qaphela umkhawulo wamanje wesixhumi;lapho udlulisa amasignali ama-high-frequency, njengezimpawu ze-high-frequency, njenge-LVDS.PCIe elinde amasignali, qaphela ukumelana kwesifunda.Isixhumi kufanele sibe nokuphikiswa kwesekethe okuphansi futhi okuzinzile, ngokuvamile amashumi e-mΩ kuya kumakhulu we-mΩ.3. Izici zemvelo yemvelo Izici zemvelo zemvelo yesixhumi ikakhulukazi zifaka: ukumelana nezinga lokushisa eliphezulu, ukumelana nomswakama, ukumelana nesifutho sikasawoti, ukudlidliza, ukushaqeka, njll. Khetha ngokuvumelana nesimo sangempela sohlelo.Uma indawo yohlelo lokusebenza imanzi futhi ibanda, ukumelana nomswakama kwesixhumi.Ukumelana nesifutho sikasawoti kucaciswe kakhulu ukuvimbela izindawo zokuthintana zensimbi zesixhumi ukuthi zingagqwali.Ku-automation yemboni, ukusebenza komthelela kwesixhumi kuyadingeka ukuthi kube phezulu ukuze kuvinjwe isixhumi ukuthi siwe ngaphansi kwezimo zokudlidliza.4. Izakhiwo ezibonakalayo Izakhiwo ezibonakalayo zesixhumi zihlanganisa amandla okufaka, ukuhlola amaphutha ezinto zokusebenza zemishini, njll. Ezixhunyweni, ukuhlolwa kwephutha kwezinto ezisebenza ngomshini kubaluleke kakhulu.Uma ifakwe ngokuhlehlayo, kungenzeka ibangele umonakalo ongenakulungiseka kumjikelezo!Amandla okufaka ahlukaniswe amandla okufaka namandla okuhlukanisa.Amazinga afanelekile ahlanganisa amandla amakhulu okufaka namandla okuhlukanisa amancane.Ngokombono wesicelo, amandla okufaka kufanele abe mancane futhi amandla okuhlukanisa kufanele abe phezulu.Ukufushane kakhulu amandla okuhlukanisa azonciphisa ukuzinza koxhumana naye, kodwa kuzixhumi okufanele zivame ukufakwa, ukushintshaniswa kwamandla okuhlukanisa kuzokwandisa isici sobunzima futhi kunciphise impilo yesevisi yemishini yemishini.Ukuze kuncishiswe amandla okuhlukaniswa kwesixhumi futhi kube lula kumakhasimende ukufaka amabhodi ahambisanayo, senze imizamo eminingi, futhi ekugcineni sathola ukukhanya emgwaqeni wokuhlola, futhi ekugcineni sasebenzisa isixhumi esiboniswe esithombeni esingezansi, futhi yashintsha i-PCB nesakhiwo sekesi lempahla.Ngokukhethekile, lesi sixhumi sinokucaciswa okuhlukile, umphumela osobala wobufakazi bephutha, amandla okufaka aphansi, amandla okuhlukanisa amaphakathi, nomuzwa omuhle wesandla lapho sifakiwe, okuthuthukisa kakhulu ukwenza kube lula kokufakwayo.Izixhumi, izixhumi ze-alias zonjiniyela bezobuchwepheshe, zisetshenziselwa ukuxhuma amabhodi esekethe amabili noma imikhiqizo ye-elekthronikhi ukuqedela ukuhanjiswa kwamandla okushintsha noma ulwazi.Ngokusho kwesixhumi, umklamo we-modular wesifunda samandla ungenziwa, yonke inqubo yenqubo yokuhlanganisa yemishini ye-elekthronikhi ingenziwa lula, futhi izimpahla zingenziwa lula ukuze zigcinwe futhi zivuselelwe.Kumasekhethi wamandla aklanywe ngokwe-modular, ukukhetha kohlobo lwesixhumi kudlala indima ebalulekile.
