Isingeniso
Izingxenye ze-elekthronikhi zomgunyathi seziphenduke indawo ebuhlungu kakhulu embonini yezingxenye.Ukusabela ezinkingeni ezivelele zokungaguquguquki kahle kweqoqo-to-batch kanye nezingxenye zomgunyathi ezisabalele, lesi sikhungo sokuhlola sihlinzeka ngokuhlaziywa komzimba okulimazayo (i-DPA), ukuhlonzwa kwezingxenye zangempela nezingelona iqiniso, ukuhlaziya izinga lohlelo lokusebenza, nokuhlaziywa kokwehluleka kwengxenye ukuhlola ikhwalithi. yezingxenye, susa izingxenye ezingafanelekile, khetha izingxenye ezinokwethenjelwa okuphezulu, futhi ulawule ngokuqinile ikhwalithi yezingxenye.
Izinto zokuhlola izingxenye ze-elekthronikhi
01 Ukuhlaziywa Komzimba Okulimazayo (i-DPA)
Uhlolojikelele lokuhlaziywa kwe-DPA:
Ukuhlaziywa kwe-DPA (I-Destructive Physical Analysis) kuwuchungechunge lwezivivinyo zomzimba ezingabhubhisi nezilimazayo kanye nezindlela zokuhlaziya ezisetshenziselwa ukuqinisekisa ukuthi ukwakheka, ukwakheka, izinto zokwakha, kanye nekhwalithi yokukhiqiza yezingxenye ze-elekthronikhi ziyahlangabezana yini nezidingo ezibekiwe zokusetshenziswa kwazo.Amasampula afanelekile akhethwa ngokungahleliwe eqoqweni lomkhiqizo oqediwe wezingxenye ze-elekthronikhi ukuze ahlaziywe.
Izinjongo Zokuhlolwa kwe-DPA:
Vimbela ukwehluleka futhi ugweme ukufaka izingxenye ezinokukhubazeka okusobala noma okungaba khona.
Nquma ukuchezuka kanye nokungasebenzi kahle kwenqubo yomkhiqizi wengxenye enqubweni yokuklama neyokukhiqiza.
Nikeza izincomo zokucubungula iqoqo nezindlela zokuthuthukisa.
Hlola futhi uqinisekise ikhwalithi yezingxenye ezinikeziwe (ukuhlolwa okuyingxenye kobuqiniso, ukuvuselela, ukwethembeka, njll.)
Izinto ezisebenzayo ze-DPA:
Izingxenye (ama-chip inductors, resistors, izingxenye ze-LTCC, ama-chip capacitor, ama-relay, amaswishi, izixhumi, njll.)
Amadivayisi ahlukahlukene (ama-diode, ama-transistors, ama-MOSFET, njll.)
Amadivayisi we-microwave
Ama-chips ahlanganisiwe
Ukubaluleka kwe-DPA ekuthengweni kwengxenye nokuhlaziywa kokufakwa esikhundleni:
Linganisa izingxenye kusukela ekubukeni kwangaphakathi kwesakhiwo kanye nenqubo ukuze uqinisekise ukwethembeka kwazo.
Gwema ngokomzimba ukusetshenziswa kwezingxenye ezilungisiwe noma eziwumgunyathi.
Amaphrojekthi nezindlela zokuhlaziya i-DPA: Umdwebo wohlelo lwangempela
02 Ukuhlolwa Kokuhlonza Ingxenye Yangempela Nengamanga
Ukuhlonza Izingxenye Zangempela Nezingelona iqiniso (okubandakanya ukulungiswa kabusha):
Ukuhlanganisa izindlela zokuhlaziya i-DPA (ingxenye), ukuhlaziywa ngokomzimba namakhemikhali kwengxenye kusetshenziselwa ukunquma izinkinga zomgunyathi nokuvuselela.
Izinto ezisemqoka:
Izingxenye (ama-capacitors, ama-resistors, ama-inductors, njll.)
Amadivayisi ahlukahlukene (ama-diode, ama-transistors, ama-MOSFET, njll.)
Ama-chips ahlanganisiwe
Izindlela zokuhlola:
I-DPA (ingxenye)
Ukuhlolwa kwe-solvent
Ukuhlolwa okusebenzayo
Ukwahlulela okuphelele kwenziwa ngokuhlanganisa izindlela ezintathu zokuhlola.
03 Ukuhlolwa Kwengxenye Yezinga Lokusebenza
Ukuhlaziywa kwezinga lohlelo lokusebenza:
Ukuhlaziywa kwesicelo sobunjiniyela kwenziwa ezingxenyeni ezingenazo izinkinga zobuqiniso nokuvuselela, ikakhulukazi kugxile ekuhlaziyweni kokumelana nokushisa (ukwendlalela) kanye nokuthengiswa kwezingxenye.
Izinto ezisemqoka:
Zonke izingxenye
Izindlela zokuhlola:
Ngokusekelwe ku-DPA, ukuqinisekiswa komgunyathi nokuvuselela, kuhilela ikakhulukazi lezi zivivinyo ezimbili ezilandelayo:
Ukuhlolwa kokugeleza kabusha kwengxenye (izimo zokugeleza kabusha ezingenamthofu) + C-SAM
Ukuhlolwa kwengxenye ye-solderability:
Indlela yebhalansi yokumanzisa, indlela yokucwilisa ibhodwe le-solder elincane, indlela yokugeleza kabusha
04 Ukuhlaziywa Kokuhluleka Kwengxenye
Ukwehluleka kwengxenye ye-elekthronikhi kubhekisela ekulahlekelweni okuphelele noma okuncane komsebenzi, ukukhukhuleka kwepharamitha, noma ukwenzeka kwezikhawu kwezimo ezilandelayo:
Ijika likabhavu: Libhekisela ekushintsheni kokwethembeka komkhiqizo phakathi nawo wonke umjikelezo wempilo yawo ukusuka ekuqaleni kuye ekuhlulekeni.Uma izinga lokuhluleka lomkhiqizo lithathwa njengenani lesici lokuthembeka kwawo, liyijika elinesikhathi sokusebenzisa njenge-abscissa kanye nezinga lokuhluleka njengokuhlanganisa.Ngenxa yokuthi ijika liphakeme kuzo zombili iziphetho futhi liphansi phakathi nendawo, licishe lifane nobhavu, yingakho igama elithi "ijika likabhavu."
