Hanyoyin gano gama gari na hukumar PCB sune kamar haka:
1, PCB allon dubawa na gani na hannu
Yin amfani da gilashin ƙara girma ko na'ura mai ƙira, duban gani na ma'aikaci shine hanya mafi al'ada ta dubawa don tantance ko allon kewayawa ya dace da lokacin da ake buƙatar ayyukan gyara. Babban fa'idodinsa shine ƙarancin farashi mai ƙima kuma babu kayan gwajin gwaji, yayin da babban lahaninsa shine kuskuren ɗan adam, babban farashi na dogon lokaci, gano lahani mai lalacewa, matsalolin tattara bayanai, da sauransu. A halin yanzu, saboda haɓakar samar da PCB, raguwa na tazarar waya da ƙarar kayan aiki akan PCB, wannan hanyar tana ƙara zama mara amfani.
2, PCB allon gwajin kan layi
Ta hanyar gano kaddarorin lantarki don gano lahani na masana'antu da gwajin analog, dijital da kayan haɗin siginar gauraya don tabbatar da cewa sun dace da ƙayyadaddun ƙayyadaddun bayanai, akwai hanyoyin gwaji da yawa kamar gwajin gadon allura da gwajin allura mai tashi. Babban fa'idodin shine ƙananan farashin gwaji a kowace jirgi, ƙarfin dijital da ƙarfin gwaji na aiki, sauri da cikakken gajeriyar gwajin da'ira, firmware na shirye-shirye, babban lahani na ɗaukar hoto da sauƙin shirye-shirye. Babban rashin amfani shine buƙatar gwada matsawa, shirye-shirye da lokacin gyarawa, farashin yin kayan aiki yana da yawa, kuma wahalar amfani yana da yawa.
3, gwajin aikin hukumar PCB
Gwajin tsarin aiki shine yin amfani da kayan gwaji na musamman a tsakiyar mataki da ƙarshen layin samarwa don aiwatar da cikakken gwajin na'urori masu aiki na allon kewayawa don tabbatar da ingancin allon kewayawa. Gwajin aiki ana iya cewa shine farkon ƙa'idar gwaji ta atomatik, wacce ta dogara akan takamaiman allo ko takamaiman naúrar kuma ana iya kammala ta ta na'urori iri-iri. Akwai nau'ikan gwajin samfur na ƙarshe, ingantaccen samfuri na baya-bayan nan, da gwajin da aka tattara. Gwajin aiki yawanci baya samar da bayanai mai zurfi kamar fil da matakan bincike matakin gyara tsari, kuma yana buƙatar kayan aiki na musamman da ƙirar gwaji na musamman. Rubutun hanyoyin gwajin aiki yana da rikitarwa don haka bai dace da yawancin layin samar da jirgi ba.
4, Ganewar gani ta atomatik
Har ila yau, an san shi azaman dubawa na gani ta atomatik, yana dogara ne akan ka'idar gani, cikakken amfani da nazarin hoto, kwamfuta da sarrafawa ta atomatik da sauran fasaha, lahani da aka fuskanta a samarwa don ganowa da sarrafawa, wata sabuwar hanya ce don tabbatar da lahani na masana'antu. Yawancin lokaci ana amfani da AOI kafin da kuma bayan sake dawowa, kafin gwajin lantarki, don inganta ƙimar karɓa yayin aikin aikin lantarki ko lokacin gwaji na aiki, lokacin da farashin gyara lahani ya fi ƙasa da farashin bayan gwajin ƙarshe, sau da yawa har sau goma.
5, gwajin X-ray ta atomatik
Yin amfani da nau'in nau'i daban-daban na abubuwa daban-daban zuwa X-ray, za mu iya gani ta cikin sassan da ake buƙatar ganowa da gano lahani. Ana amfani da shi ne don gano ultra-fine farar da ultra-high density circuits da lahani kamar gada, guntu da aka rasa da rashin daidaituwa da aka haifar a cikin tsarin taro, kuma yana iya gano lahani na ciki na kwakwalwan IC ta amfani da fasahar hoto na hoto. A halin yanzu ita ce hanya ɗaya tilo don gwada ingancin walda na grid grid da ƙwallan da aka karewa. Babban fa'idodin shine ikon gano ingancin walda na BGA da abubuwan da aka haɗa, babu farashin daidaitawa; Babban rashin lahani shine jinkirin saurin gudu, ƙarancin gazawa, wahalar gano kayan haɗin da aka sake yin aiki, tsada mai tsada, da tsawon lokacin haɓaka shirin, wanda shine sabon hanyar ganowa kuma yana buƙatar ƙarin nazari.
6, tsarin gano Laser
Shine sabon ci gaba a fasahar gwajin PCB. Yana amfani da katako na Laser don bincika allon da aka buga, tattara duk bayanan auna, da kwatanta ainihin ƙimar ƙimar da aka saita ta cancantar ƙimar iyaka. An tabbatar da wannan fasaha a kan faranti masu haske, ana la'akari da shi don gwajin farantin taro, kuma yana da sauri don samar da layin samar da yawa. Fitowa da sauri, babu buƙatun kayan aiki da samun damar gani ba tare da rufe fuska ba shine babban fa'idodinsa; Babban farashi na farko, kulawa da matsalolin amfani shine babban gazawarsa.
7, gano girman
Ana auna girman matsayin rami, tsayi da faɗi, da matakin matsayi ta kayan auna hoto huɗu. Tunda PCB ƙarami ne, sirara da nau'in samfuri mai laushi, ma'aunin lamba yana da sauƙi don samar da nakasu, yana haifar da rashin daidaituwa, kuma kayan auna hoto mai girma biyu ya zama mafi kyawun ma'aunin ma'aunin ma'auni mafi kyau. Bayan an tsara kayan aikin auna hoton na ma'aunin Sirui, zai iya gane ma'auni ta atomatik, wanda ba wai kawai yana da daidaiton ma'auni ba, amma kuma yana rage lokacin aunawa sosai kuma yana inganta ingancin ma'aunin.
