Ama-inductors kagesi e-SMD angenye ye-metallic glass uranium resistors. I-inductance yemodi evamile, eyaziwa nangokuthi imodi evamile yokuminyanisa, ivame ukusetshenziselwa ukuhlunga amasiginali wokuphazamiseka kagesi wemodi evamile ekushintsheni kwamandla ekhompyutha. Ekwakhiweni kwebhodi lesifunda, i-inductor yemodi evamile iphinda isebenze njengesihlungi se-EMI ukucindezela igagasi kazibuthe elikhiqizwe umugqa wesiginali wesivinini esikhulu ukusuka ekukhanyeni ukuya ngaphandle. Kuyi-resistor eyenziwe ngengxube yempushana yensimbi kanye nempushana yengilazi ye-uranium, ephrintwa isikrini ku-inductor yamandla aphezulu we-SMD ku-substrate. Ukumanzisa okuhle, ukumelana nokushisa okuphezulu, i-coefficient yokushisa ephansi. Ukusetshenziswa kobuchwepheshe bokuhlanganiswa okujwayelekile kuye kwanda kakhulu, futhi ingxenye yemikhiqizo ye-elekthronikhi eqoqwe yi-SMT idlule ama-90%. izwe lami bekumele lingene kumakhono e-SMT kusukela ngawo-1980. Ngokuthuthukiswa kwemishini emincane yokukhiqiza ye-SMT, ububanzi bokusetshenziswa kwezigaba ze-SMT buye bandiswa. Indiza, i-aerospace, i-instrumentation, amathuluzi omshini nezinye izigaba zisebenzisa i-SMT ukukhiqiza amaqoqo amancane ahlukahlukene emikhiqizo ye-elekthronikhi noma izingxenye.
Ama-resistors abizwa ngawodwana ngokuthi ama-resistors empilweni yansuku zonke. I-elementi ekhawulayo yamanje exhunywe kusiphikisa kusekethi. I-resistor inenani elinqunyiwe lamaphini amabili futhi isetshenziselwa ukukhawulela okwamanje egeleza egatsheni lapho ixhunywe khona. Ukuphikiswa okunenani lokumelana elingenakushintshwa kubizwa ngokuthi ukumelana okungaguquki. Labo abanokumelana okuguquguqukayo babizwa ngokuthi ama-potentiometers noma ama-variable resistors. Ukumelana ne-virtual kuqondile, okungukuthi, isikhashana samanje ngokusebenzisa ukumelana silingana ne-voltage yesikhashana esetshenzisiwe. I-Resistor eguquguqukayo yesihlukanisi se-voltage. Okukodwa noma okubili okuthintana naye kwensimbi cindezela uqine kusiphikisa esiveziwe. Indawo yokuxhumana inquma ukumelana phakathi kwanoma iyiphi indawo yesiphikisa kanye noxhumana naye.
Izici zemikhiqizo yabakhiqizi be-inductor ye-SMD
Usayizi omncane nesisindo esincane; · Ifanele i-reflow soldering kanye ne-wave soldering; · Injini ingaba namandla futhi iqine; · Izindleko eziphansi zokuhlanganisa, ezihambisana nemishini yokufaka esebenzayo; · Amandla aphezulu emishini kanye nezici zefrikhwensi ephezulu. Ukuze kuvikelwe izintambo, izihibe namakhoyili avela endaweni kazibuthe yangaphandle futhi kuncishiswe umthelela wokuphazamiseka wenkundla kazibuthe okhiqizwa isekethe kwezinye izingxenye, ukuvikela kazibuthe noma izindlela zokuvikela i-electromagnetic ngokuvamile ziyamukelwa.
Yiziphi izinto ezenziwe ngama-inductors amandla e-SMD?
Ama-resistors e-SMT enziwa ngokwehlukana kusuka kudatha elandelayo:
Izinto eziyisisekelo ziyi-alumina, futhi idatha yokumelana i-ruthenium oxide
1. I-substrate
2. Unamathisela wokumelana
3. Phinda ukwaziswa
4. Idatha yesiqondiso esihle kanye nedatha yesiqondiso eseceleni
5. Ukugcinwa okuyisisekelo kwengilazi G16. Ukugcinwa kwesibili kwengilazi G27.
