Intshayelelo
Izixhobo ze-elektroniki zomgunyathi ziye zaba yintlungu enkulu kwishishini lecandelo.Ukuphendula kwiingxaki eziphambili zokungaguquguquki kwe-batch-to-batch kunye nezinto zomgunyathi ezixhaphakileyo, eli ziko lovavanyo libonelela ngohlalutyo lomzimba olonakalisayo (DPA), ukuchongwa kwezinto eziyinyani kunye nezobunyani, uhlalutyo lwenqanaba lesicelo, kunye nohlalutyo lokusilela kwecandelo ukuvavanya umgangatho. yamacandelo, susa amacandelo angafanelekanga, khetha amacandelo athembeke kakhulu, kwaye ulawule ngokungqongqo umgangatho wamacandelo.
Izinto zovavanyo lwamacandelo e-elektroniki
01 uHlahlelo loMzimba olonakalisayo (DPA)
Isishwankathelo soHlahlelo lweDPA:
Uhlalutyo lwe-DPA (Uhlalutyo loMzimba olonakalisayo) luluhlu lweemvavanyo zomzimba ezingonakalisi kwaye zitshabalalisayo kunye neendlela zokuhlalutya ezisetyenziselwa ukuqinisekisa ukuba uyilo, ulwakhiwo, izixhobo, kunye nomgangatho wokwenziwa kwezixhobo ze-elektroniki ziyahlangabezana neemfuno ezichaziweyo zokusetyenziswa kwazo.Iisampulu ezifanelekileyo zikhethwe ngokungenamkhethe kwibhetshi yemveliso egqityiweyo yamacandelo e-elektroniki ukuze kuhlalutywe.
Iinjongo zoVavanyo lwe-DPA:
Thintela ukusilela kwaye ugweme ukufakela amacandelo aneziphene ezicacileyo okanye ezinokubakho.
Qinisekisa ukutenxa kunye neziphene zenkqubo yomenzi wecandelo kuyilo kunye nenkqubo yokuvelisa.
Ukubonelela ngeengcebiso zokusetyenzwa kweebhetshi kunye namanyathelo okuphucula.
Hlola kwaye uqinisekise umgangatho wamacandelo anikezelweyo (uvavanyo oluyinxenye lokunyaniseka, ukulungiswa, ukuthembeka, njl.)
Izinto ezinokusetyenziswa ze-DPA:
Amacandelo (ii-chip inductors, resistors, LTCC components, chip capacitors, relays, switches, connectors, njl.)
Izixhobo ezikhethekileyo (iidiode, iitransistor, iiMOSFET, njl.njl.)
Izixhobo zeMicrowave
Iitshiphusi ezidityanisiweyo
Ukubaluleka kwe-DPA ekuthengeni icandelo kunye novavanyo lokutshintsha:
Vavanya amacandelo kulwakhiwo lwangaphakathi kunye neembono zenkqubo ukuqinisekisa ukuthembeka kwazo.
Kuphephe ngokwasemzimbeni ukusetyenziswa kwezinto ezihlaziyiweyo okanye ezomgunyathi.
Iiprojekthi zohlalutyo lwe-DPA kunye neendlela: Eyona dayagram yesicelo
02 Uvavanyo lokuchongwa kweCandelo lokwenyani kunye nenkohliso
Ukuchongwa kwaMalunga oNgenene kunye nawoMgunyathi (kubandakanywa nohlaziyo):
Ukudibanisa iindlela zokuhlalutya i-DPA (inxalenye), uhlalutyo lomzimba kunye neekhemikhali zecandelo lisetyenziselwa ukugqiba iingxaki zomgunyathi kunye nokulungiswa.
Izinto eziphambili:
Amacandelo (i-capacitors, resistors, inductors, njl.
Izixhobo ezikhethekileyo (iidiode, iitransistor, iiMOSFET, njl.njl.)
Iitshiphusi ezidityanisiweyo
Iindlela zovavanyo:
I-DPA (ngokuyinxenye)
Uvavanyo lokunyibilikisa
Uvavanyo olusebenzayo
Isigwebo esibanzi senziwa ngokudibanisa iindlela ezintathu zokuvavanya.
03 Uvavanyo lweCandelo lwenqanaba losetyenziso
Uhlalutyo lwenqanaba losetyenziso:
Uhlalutyo lwesicelo sobunjineli luqhutyelwa kumacandelo angenayo imiba yokunyaniseka kunye nokulungiswa, ngokukodwa kugxininise kuhlalutyo lokumelana nokushisa (i-layering) kunye ne-solderability yamacandelo.
Izinto eziphambili:
Onke amacandelo
Iindlela zovavanyo:
Ngokusekwe kwi-DPA, inkohliso kunye nokuqinisekiswa ngokutsha, kubandakanya ikakhulu olu vavanyo lumbini lulandelayo:
Uvavanyo lokuqukunjelwa kwecandelo (iimeko zokuphinda ziqhutyelwe simahla) + C-SAM
Uvavanyo lwecandelo lokuthengiselana:
Indlela yokumanzisa ibhalansi, indlela yokuntywilisela imbiza ye-solder encinci, indlela yokubuyisela kwakhona
04 Uhlalutyo lokungaphumeleli kweCandelo
Ukungaphumeleli kwecandelo le-elektroniki kubhekiselele kulahleko olupheleleyo okanye oluyinxenye lomsebenzi, iparameter drift, okanye ukwenzeka okuphakathi kwezi meko zilandelayo:
Ijiko lebhafu: Ibhekisa kutshintsho lokuthembeka kwemveliso ngexesha lomjikelo wobomi bayo bonke ukusuka ekuqaleni ukuya kukusilela.Ukuba izinga lokungaphumeleli kwemveliso lithathwa njengexabiso leempawu zokuthembeka kwayo, ijika kunye nexesha lokusetyenziswa njenge-abscissa kunye nesantya sokungaphumeleli njengokulungelelanisa.Kuba igophe liphezulu kuzo zombini iziphelo kwaye lisezantsi embindini, lifana nebhafu, kungoko igama elithi "igophe lebhafu."
