Sanibonani nonke, yimina mhleli.Kunezinhlobo eziningi zezixhumi.Izinhlobo ezijwayelekile zifaka amatheminali okuxhumana, amatheminali ezintambo, izixhumi zezintambo kuya ebhodini, nezixhumi zebhodi ukuya ebhodini.Isigaba ngasinye singahlukaniswa ngezigaba eziningana, njengalezi: izixhumi zebhodi ukuya ebhodini zihlanganisa izihloko nezinsikazi, izixhumi zebhodi ukuya ebhodini, njll.;izixhumi ze-wire-to-board zihlanganisa izixhumi ze-FPC, amasokhethi e-IDC, amasokhethi ezimpondo ezilula, njll. Ngakho-ke lapho sikhetha isixhumi, yimaphi ama-engeli okufanele sicabangele isixhumi esifanele ukusetshenziswa kwehadiwe?
1. Izikhonkwane kanye nezikhala
Inombolo yamaphini kanye nesikhala phakathi kwamaphini kuyisisekelo esiyisisekelo sokukhetha isixhumi.Inani lamaphini akhethelwe isixhumi lincike enanini lamasignali azoxhunywa.Kwezinye izixhumi ze-patch, inani lezikhonkwane ezihlokweni ze-patch njengoba kukhonjisiwe esithombeni esingezansi akufanele libe liningi kakhulu.Ngenxa yokuthi ohlelweni lwe-soldering yomshini wokubeka, ngenxa yokushisa okuphezulu, ipulasitiki yesixhumi izofudumala futhi ikhubazeke, futhi ingxenye ephakathi izoqhuma, okuholela ekuthungeni okungamanga kwezikhonkwane.Ekuthuthukisweni kwangaphambi kwesikhathi komhleli wethu we-P800Flash, lesi sihloko kanye nesihloko sikamama kwasetshenziselwa ukuxhumanisa ibhodi nebhodi.Ngenxa yalokho, izikhonkwane zesihloko se-prototype zathengiswa ezindaweni ezinkulu.Ngemva kokushintshela kuzihloko zamaphinikhodi angu-2 anamaphini ahhafu, akuzange kube khona ukusoda okungamanga.
Ezinsukwini zanamuhla, okokusebenza kwe-elekthronikhi kuthuthukela ekusetshenzisweni okuncane kanye nokunemba, futhi iphimbo lephinikhodi yesixhumi nalo selishintshile lisuka ku-2.54mm laya ku-1.27mm laya ku-0.5mm.Uma iphimbo lomthofu lincane, ziba phezulu izidingo zenqubo yokukhiqiza.Isikhala somthofu kufanele sinqunywe yizinga lobuchwepheshe bokukhiqiza benkampani, siphishekele ngokungaboni isikhala esincane
2. Ukusebenza kukagesi
Ukusebenza kukagesi kwesixhumi ikakhulukazi kuhlanganisa: ukukhawulela okwamanje, ukumelana nokuxhumana, ukumelana nokufakwa kwe-insulation namandla e-dielectric, njll. Uma uxhuma ukunikezwa kwamandla aphezulu, qaphela umkhawulo wamanje wesixhumi;lapho udlulisa amasiginali wemvamisa ephezulu njenge-LVDS, PCIe, njll., naka ukumelana nokuxhumana.Isixhumi kufanele sibe nokumelana okuphansi nokungaguquki kokuxhumana, ngokuvamile amashumi e-mΩ kuya kumakhulu we-mΩ.
IZIXHUMANISI ZEBHHODI ELIYA IBHODI :0.4MM(.016″) SMD H:1.5MM ISIKHUNGO 10-100PIN
3. Ukusebenza kwemvelo
Ukusebenza kwemvelo kwesixhumi kufaka phakathi: ukumelana nezinga lokushisa, umswakama, isifutho sikasawoti, ukudlidliza, ukushaqeka, njll. Khetha ngokuya ngendawo ethile yohlelo lokusebenza.Uma indawo yokufaka isicelo inomswakama uma kuqhathaniswa, izidingo zokumelana nomswakama nesifutho sikasawoti sesixhumi ziphezulu ukuze kugwenywe ukugqwala kokuthintana kwensimbi yesixhumi.Emkhakheni wokulawulwa kwezimboni, izimfuneko zokunqanda ukudlidliza nokusebenza kokushaqeka kwesixhumi ziphezulu ukuvimbela isixhumi ukuthi siwe ngesikhathi senqubo yokudlidliza.
Ukuhlola kwangempela kubonisa ukuthi ngenxa yendlela eyingqayizivele yesokhethi, lesi sixhumi sinemiphumela esobala yobufakazi obungahlakaniphile, amandla amancane okufaka, amandla okuhlukanisa amaphakathi, nomuzwa omuhle we-plug-in, okuthuthukisa kakhulu ukusebenziseka kwezingxenye ze-plug-in.
Izixhumi, ezivame ukubizwa ngokuthi izixhumi ngonjiniyela, zisetshenziselwa ukuxhuma amabhodi esekethe amabili noma izinto zikagesi ukuze kuzuzwe amandla noma ukudluliswa kwesignali.Ngesixhumi, isekethe ingenziwa imodular, inqubo yokuhlanganisa yomkhiqizo we-elekthronikhi ingenziwa lula, futhi umkhiqizo ungagcinwa kalula futhi uthuthukiswe.Kumasekhethi e-modular, ukukhethwa kwezixhumi kudlala indima enqumayo.
