Molweni nonke, ndingumhleli.Kukho iintlobo ezininzi zezixhumanisi.Iindidi eziqhelekileyo zibandakanya iitheminali ze-interface yonxibelelwano, iitheminali zocingo, i-wire-to-board connectors, kunye nezixhumi zebhodi ukuya ebhodini.Udidi ngalunye lunokwahlulwa lube ngamacandelo amaninzi, njengale: ibhodi-ibhodi edibanisa ibhodi-ibhodi edibanisa i-headers kunye nabasetyhini, izixhumi zebhodi ukuya kwibhodi, njl.;ngocingo-to-ibhodi izihlanganisi ziquka izihlanganisi FPC, iisokethi IDC, iisokethi ezilula uphondo, njalo njalo. Ngoko xa ukhetha isidibaniso, ukusuka apho kufuneka sicinge isinxibelelanisi esilungele ukusetyenziswa hardware?
1. Izikhonkwane kunye nezithuba
Inani lezikhonkwane kunye nesithuba phakathi kwezikhonkwane zisisiseko esisisiseko sokukhetha isinxibelelanisi.Inani lezikhonkwane ezikhethiweyo kwikhonkco lixhomekeke kwinani leempawu eziza kudityaniswa.Kwezinye izihlanganisi zepatch, inani lezikhonkwane kwi-patch headers njengoko kubonisiwe kumzobo ongezantsi akufanele kube kakhulu.Ngenxa yokuba kwinkqubo ye-soldering yomatshini wokubeka, ngenxa yokushisa okuphezulu, iplastiki yesinxibelelanisi iya kufudumeza kwaye ikhubazeke, kwaye inxalenye ephakathi iya kukhupha, okubangela ukuba i-soldering yobuxoki yezikhonkwane.Kuphuhliso lwangethuba lomdwelisi wenkqubo weP800Flash, le ntloko kunye nentloko kamama zisetyenziselwe uqhagamshelo lwebhodi ukuya kwibhodi.Ngenxa yoko, izikhonkwane zentloko yeprototype zathengiswa kwiindawo ezinkulu.Emva kokutshintshela kwi-header ye-pin enama-halfed pins, kwakungekho i-soldering yobuxoki.
Kule mihla, izixhobo ze-elektroniki ziphuhlisa kwi-miniaturization kunye nokuchaneka, kwaye i-pin pitch yesiqhagamshelo nayo itshintshile ukusuka kwi-2.54mm ukuya kwi-1.27mm ukuya kwi-0.5mm.Okukhona i-pitch ekhokelayo incinci, iphezulu iimfuno zenkqubo yemveliso.Isithuba esikhokelayo kufuneka simiselwe linqanaba letekhnoloji yemveliso yenkampani, ukulandela ngokungaboniyo isithuba esincinci
2. Ukusebenza kombane
Ukusebenza kombane kwesiqhagamshelo ikakhulu kubandakanya: ukukhawulela okwangoku, ukuchasana noqhagamshelwano, ukunyanzeliswa kwe-insulation kunye namandla e-dielectric, njl. Xa udibanisa ukunikezelwa kwamandla aphezulu, qwa lasela ingqalelo kumda womda wokudibanisa;xa uhambisa izibonakaliso eziphezulu ze-frequency ezifana ne-LVDS, i-PCIe, njl., nikela ingqalelo ekuxhathiseni uqhagamshelwano.Isidibanisi kufuneka sibenoxhathiso olusezantsi noluqhubekayo loqhagamshelwano, ngokubanzi amashumi e-mΩ ukuya kumakhulu e-mΩ.

3. Ukusebenza kwendalo
Ukusebenza kokusingqongileyo kwesihlanganisi ikakhulu kubandakanya: ukumelana nobushushu, ukufuma, ukutshiza ityuwa, ukungcangcazela, ukothuka, njl.Ukuba indawo yesicelo inomswakama, iimfuno zokuchasana nokufuma kunye netyuwa yokutshiza isihlanganisi ziphezulu ukuphepha ukubola koqhagamshelwano lwentsimbi yesidibaniso.Kwintsimi yolawulo lwemizi-mveliso, iimfuno zokuchasana nokungcangcazela kunye nokusebenza kothusayo komdibaniso ziphezulu ukuthintela umdibaniso ukuba angawi ngexesha lenkqubo yokungcangcazela.
Uvavanyo oluyinyani lubonisa ukuba ngenxa yesalathiso esikhethekileyo sesokethi, esi sidibanisi sineziphumo ezicacileyo zobungqina bobudenge, amandla amancinci okufaka, amandla okwahlukana aphakathi, kunye nokuziva kakuhle kweplagi, ephucula kakhulu ukusebenziseka kweendawo zeplagi.
Iziqhagamshelo, ezidla ngokubizwa ngokuba ziinjineli, zisetyenziselwa ukudibanisa iibhodi ezimbini zeesekethe okanye izixhobo zombane ukuphumeza amandla okanye ukuhanjiswa komqondiso.Ngokusebenzisa isiqhagamshelo, isiphaluka sinokuhlengahlengiswa, inkqubo yendibano yemveliso ye-elektroniki inokwenziwa lula, kwaye imveliso inokugcinwa lula kwaye iphuculwe.Kwiisekethe zemodyuli, ukukhethwa kweziqhagamshelo kudlala indima ebalulekileyo.
