Inqubo yokucubungula isichibi se-PCBA iyinkimbinkimbi kakhulu, okuhlanganisa inqubo yokukhiqiza ibhodi le-PCB, ukuthengwa nokuhlolwa kwengxenye, umhlangano wesichibi se-SMT, i-plug-in ye-DIP, ukuhlolwa kwe-PCBA nezinye izinqubo ezibalulekile.Phakathi kwazo, ukuhlolwa kwe-PCBA kuyisixhumanisi sokulawula ikhwalithi esibaluleke kakhulu kuyo yonke inqubo yokucubungula ye-PCBA, enquma ukusebenza kokugcina komkhiqizo.Ngakho yimaphi amafomu okuhlola e-PCBA?Kuyini ukuhlolwa kwe-pcba
Inqubo yokucubungula isichibi se-PCBA iyinkimbinkimbi kakhulu, okuhlanganisa inqubo yokukhiqiza ibhodi le-PCB, ukuthengwa nokuhlolwa kwengxenye, umhlangano wesichibi se-SMT, i-plug-in ye-DIP, ukuhlolwa kwe-PCBA nezinye izinqubo ezibalulekile.Phakathi kwazo, ukuhlolwa kwe-PCBA kuyisixhumanisi sokulawula ikhwalithi esibaluleke kakhulu kuyo yonke inqubo yokucubungula ye-PCBA, enquma ukusebenza kokugcina komkhiqizo.Ngakho-ke athini amafomu okuhlola e-PCBA?Ukuhlolwa kwe-PCBA kufaka phakathi: Ukuhlolwa kwe-ICT, ukuhlolwa kwe-FCT, ukuhlolwa kokuguga, ukuhlolwa kokukhathala, ukuhlolwa kwemvelo okunokhahlo lawa mafomu amahlanu.
I-1, ukuhlolwa kwe-ICT ikakhulukazi kufaka phakathi isekethe ekuvaliwe, amanani kagesi kanye namanje kanye nejika lamagagasi, i-amplitude, umsindo, njll.
2, Ukuhlolwa kwe-FCT kudinga ukwenza ukudubula kohlelo lwe-IC, kulingise ukusebenza kwayo yonke ibhodi ye-PCBA, kutholwe izinkinga ku-hardware ne-software, futhi kufakwe isichibiyelo esidingekayo sokucutshungulwa kokukhiqiza kanye nerack yokuhlola.
3, ukuhlolwa kokukhathala ikakhulukazi ukusampula ibhodi le-PCBA, nokwenza umsebenzi we-high-frequency kanye nesikhathi eside, ubheke ukuthi ukwehluleka kwenzeka, ukwahlulela amathuba okuhluleka esivivinyweni, kanye nempendulo ngokusebenza kwe-PCBA. ibhodi emikhiqizweni ye-elekthronikhi.
4, ukuhlolwa endaweni enokhahlo ikakhulukazi ukuveza ibhodi le-PCBA ezingeni lokushisa, umswakama, ukwehla, ukuchaphaza, ukudlidliza kwenani elilinganiselwe, ukuthola imiphumela yokuhlolwa kwamasampula angahleliwe, ukuze kutholwe ukwethembeka kwayo yonke ibhodi ye-PCBA. iqoqo.
I-5, ukuhlolwa kokuguga ikakhulukazi ukunika amandla ibhodi le-PCBA nemikhiqizo ye-elekthronikhi isikhathi eside, igcine isebenza futhi ibheke ukuthi kukhona yini ukwehluleka, ngemuva kokuguga kokuhlolwa kwemikhiqizo ye-elekthronikhi ingathengiswa ngamaqoqo.Inqubo yePCBA iyinkimbinkimbi, ekukhiqizeni futhi inqubo yokucubungula, kungase kube nezinkinga ezihlukahlukene ngenxa yemishini engafanele noma ukusebenza, ayikwazi ukuqinisekisa ukuthi imikhiqizo ekhiqizwayo ifanelekile, ngakho-ke kuyadingeka ukwenza ukuhlolwa kwe-PCB ukuze kuqinisekiswe ukuthi umkhiqizo ngamunye ngeke ube nezinkinga zekhwalithi.
Ungayihlola kanjani i-pcba
Izindlela ezijwayelekile zokuhlola i-PCBA, ikakhulukazi lezi ezilandelayo:
1. Ukuhlola okwenziwa ngesandla
Ukuhlola okwenziwa ngesandla wukuthembela ngokuqondile embonweni ukuhlola, ngombono nokuqhathanisa ukuze kuqinisekiswe ukufakwa kwezingxenye ku-PCB, lobu buchwepheshe busetshenziswa kakhulu.Kodwa-ke, inani elikhulu kanye nezingxenye ezincane zenza le ndlela ibe ngaphansi futhi ingafanelekile.Ngaphezu kwalokho, okunye ukukhubazeka kokusebenza akubonakali kalula futhi ukuqoqwa kwedatha kunzima.Ngale ndlela, izindlela zokuhlola ezichwepheshile ziyadingeka.
2, Ukuhlola okuzenzakalelayo kwe-Optical (AOI)
Ukutholwa okuzenzakalelayo kokubona, okubuye kwaziwe ngokuthi ukuhlolwa kokubona okuzenzakalelayo, kwenziwa umtshina okhethekile, osetshenziswa ngaphambi nangemva kwe-reflux, futhi i-polarity yezingxenye ingcono.Kulula ukulandela ukuxilongwa kuyindlela evamile, kodwa le ndlela impofu ekuhlonzeni isifunda esifushane.
3, umshini wokuhlola inaliti endizayo
Ukuhlolwa kwenaliti sekuthole ukuduma eminyakeni embalwa edlule ngenxa yokuthuthuka kokunemba komshini, isivinini, nokwethembeka.Ukwengeza, isidingo samanje sesistimu yokuhlola enokuguqulwa okusheshayo kanye nekhono elingena-jig elidingekayo ekukhiqizeni i-Prototype kanye nokukhiqizwa kwevolumu ephansi kwenza ukuhlolwa kwenaliti endizayo kube ukukhetha okungcono kakhulu.4.Ukuhlola okusebenzayo
Lena indlela yokuhlola ye-PCB ethile noma iyunithi ethile, eyenziwa amathuluzi akhethekile.Kunezinhlobo ezimbili eziyinhloko zokuhlola ukusebenza: Ukuhlolwa Kokugcina Komkhiqizo kanye ne-Hot Mock-up.
5. I-Manufacturing Defect Analyzer (MDA)
Izinzuzo eziyinhloko zale ndlela yokuhlola izindleko eziphansi zangaphambili, ukuphuma okuphezulu, ukulandela ukuxilongwa okulula kanye nesekhethi efushane ephelele esheshayo kanye nokuhlolwa kwesekethe evulekile.Ububi ukuthi ukuhlolwa kokusebenza akukwazi ukwenziwa, ngokuvamile alukho inkomba embozwe yokuhlola, indawo kufanele isetshenziswe, futhi izindleko zokuhlola ziphezulu.
imishini yokuhlola i-pcba
Imishini ejwayelekile yokuhlola i-PCBA yilezi: Umhloli we-ICT eku-inthanethi, ukuhlolwa okusebenzayo kwe-FCT nokuhlolwa kokuguga.
1, umhloli we-inthanethi we-ICT
I-ICT iwukuhlola okuzenzakalelayo okuku-inthanethi, okunezinhlobonhlobo zezinhlelo zokusebenza futhi kulula ukuyisebenzisa.Umtshina we-ICT othomathikhi we-inthanethi ikakhulukazi owokulawula inqubo yokukhiqiza, ungakala ukumelana, amandla, inductance, isifunda esihlanganisiwe.Isebenza ngokukhethekile ekutholeni isifunda esivulekile, isifunda esifushane, umonakalo wengxenye, njll., indawo enephutha enembile, ukulungiswa okulula.
2. Ukuhlolwa kokusebenza kwe-FCT
Ukuhlolwa komsebenzi we-FCT ukuhlinzeka ngendawo yokusebenza yokulingisa efana nesasasa nomthwalo webhodi le-PCBA, nokuthola amapharamitha ahlukahlukene ebhodi ukuze kuhlolwe ukuthi ingabe amapharamitha okusebenza ebhodi ayahlangabezana yini nezimfuneko zedizayini.Izinto zokuhlola ukusebenza kwe-FCT ikakhulukazi zifaka i-voltage, yamanje, amandla, isici samandla, imvamisa, umjikelezo wemisebenzi, ukukhanya nombala, ukubonwa kwezinhlamvu, ukubonwa kwezwi, ukukalwa kwezinga lokushisa, ukulinganisa ingcindezi, ukulawula ukunyakaza, i-FLASH kanye nokushiswa kwe-EEPROM.
3. Ukuhlolwa kokuguga
Ukuhlolwa kokuguga kusho inqubo yokulingisa izici ezihlukahlukene ezihilelekile kuzimo zangempela zokusetshenziswa komkhiqizo ukuze kwenziwe isilingo esihambisanayo sokuthuthukisa isimo.Ibhodi ye-PCBA yemikhiqizo ye-elekthronikhi ingasetshenziswa isikhathi eside ukulingisa ukusetshenziswa kwamakhasimende, ukuhlola okokufaka/okuphumayo ukuze kuqinisekiswe ukuthi ukusebenza kwayo kuhlangabezana nesidingo semakethe.
Lezi zinhlobo ezintathu zemishini yokuhlola zivamile enqubweni ye-PCBA, futhi ukuhlolwa kwe-PCBA enqubweni yokucubungula ye-PCBA kungaqinisekisa ukuthi ibhodi le-PCBA elethwa ekhasimendeni lihlangabezana nezidingo zedizayini yekhasimende futhi kunciphisa kakhulu izinga lokulungisa.
