Indlela yokukhetha izixhumi ezifanele zebhodi ukuya ebhodini

Ngakho-ke lapho sikhetha isixhumi, kufanele sicabangele isixhumi esifanele ukusetshenziswa kwehadiwe kusuka ngamuphi umbono?

1. Izikhonkwane, Pitch

Inombolo yephinikhodi nesikhala sephinikhodi kuyisisekelo esiyisisekelo sokukhetha isixhumi. Zingaki izinombolo zephinikhodi zezixhumi ozikhethayo zincike enanini lamasignali adinga ukuxhunywa. Kwezinye izixhumi zokuchibiyela, iphinikhodi yerowu yesichibi eboniswe emfanekisweni olandelayo akufanele ibe amaphini amaningi kakhulu. Ngoba inqubo yokushisela yomshini we-SMT, ngenxa yokushisa okuphezulu, ipulasitiki yesixhumi izoshiswa futhi ikhubazeke, futhi i-bulge ephakathi izobangela ukushisela okubonakalayo kwephini. Esigabeni sokuqala sokuthuthukiswa komhleli wethu we-P800Flash, sasebenzisa lolu hlobo lwephinikhodi nebha ukuze senze uxhumano phakathi kwamabhodi, futhi umphumela waba ukuthi iphinikhodi ye-prototype pin yayishiselwe endaweni enkulu. Ngemva kokufaka izikhonkwane ezimbili esikhundleni senombolo yezikhonkwane, kwakungekho ukushisela okungamanga.

Kulezi zinsuku, izinto zikagesi zithuthukela ekusetshenzisweni okuncane kanye nokunemba, futhi ukuhlukaniswa kwamaphini wezixhumi nakho kusuka ku-2.54mm kuya ku-1.27mm kuya ku-0.5mm. Uma isikhala sephini sincane, ziphakama kakhulu izidingo zenqubo yokukhiqiza. Ukuhlukaniswa kwamaphini kufanele kunqunywe izinga lenqubo yokukhiqiza yenkampani, nokuphishekela ukungaboni ngaso linye kwesikhala esincane

2. Ukusebenza kukagesi

Ukusebenza kukagesi kwesixhumi ikakhulukazi kuhlanganisa: umkhawulo wamanje, ukumelana nokuxhumana, ukumelana nokushisa kanye namandla kagesi. Uma uxhuma ukunikezwa kwamandla aphezulu, naka umkhawulo wamanje wesixhumi; Lapho uthumela amasignali amaza aphezulu njengezimpawu ze-LVDS ne-PCIe, naka ukumelana nokuxhumana. Isixhumi kufanele sibe nokumelana nokuxhumana okuphansi nokungaguquki, ngokuvamile amashumi e-mΩ ukuya kumakhulu we-mΩ.

3. Ukusebenza kwemvelo

Ukusebenza kwemvelo kwesixhumi kuhlanganisa ikakhulukazi: ukumelana nezinga lokushisa, ukumelana nomswakama, ukumelana nosawoti spray, vibration, umthelela nokunye. Khetha ngokuya ngendawo yohlelo lokusebenza ethile. Uma indawo yokufaka isicelo inomswakama, ukumelana nomswakama wesixhumi kanye nokumelana nesifutho sikasawoti kuyadingeka ukuze kugwenywe ukugqwala kokuthintana kwensimbi yesixhumi. Emkhakheni wokulawulwa kwezimboni, ukumelana komthelela wokudlidliza kwesixhumi kuyadingeka ukuthi kube phezulu, ukuze kugwenywe ukuthi isixhumi siwe ngesikhathi sokudlidliza.

4. Izakhiwo zemishini

Izici zemishini yesixhumi zihlanganisa amandla okuxhuma, i-anti-stay yemishini, njll. I-anti-stay yemishini ibaluleke kakhulu kusixhumi, uma sesifakiwe, kungenzeka sibangele umonakalo ongenakulungiseka kumjikelezo!

Amandla okufaka ahlukaniswe amandla okufaka namandla okuhlukanisa. Kunezinhlinzeko ezindinganisweni ezifanele zamandla amakhulu okufaka namandla okuhlukanisa amancane, ngokombono wokusetshenziswa, amandla okufaka kufanele abe mancane, amandla okuhlukanisa kufanele abe makhulu. Amandla okuhlukanisa amancane kakhulu azonciphisa ukwethembeka kokuxhumana, kodwa ezixhumi ngokuvamile ezidinga ukuxhunywa futhi zingaxhunywanga, amandla okuhlukanisa amaningi azokwandisa ubunzima bokudonsa futhi kunciphise impilo yemishini.
