Wadanne kayan aiki da ayyuka ake buƙata don samarwa PCBA?

Samar da PCBA yana buƙatar kayan aiki na asali kamarSMT soldering manna firinta, Injin SMT, sake kwararatanda, AOIinji, Bangaren fil shearing inji, kalaman soldering, tin makera, farantin wanki inji, ICT gwajin tsayarwa, FCT gwajin tsayarwa, tsufa gwajin tara, da dai sauransu PCBA aiki shuke-shuke na daban-daban masu girma dabam suna sanye take da daban-daban kayan aiki.

1.SMT bugu na'ura

Na'urar bugu ta zamani gabaɗaya ta ƙunshi ɗorawa faranti, ƙara manna solder, embossing, watsa allo da sauransu.Ka'idar aikinsa ita ce: da farko, allon da'irar da aka buga yana daidaitawa akan tebur ɗin bugu, sannan hagu da dama na na'urar bugu suna canja wurin solder manna ko jan manne zuwa farantin da ya dace ta hanyar ragar karfe, sannan PCB tare da bugu iri ɗaya shine shigarwa zuwa na'urar SMT ta hanyar tebur watsa don SMT ta atomatik.

2.Mashin sanyawa

SMT: wanda aka fi sani da "Surface Mount System", a cikin samar da layin, an saita shi bayan na'urar buga bugu na solder, na'ura ce ta motsa shugaban SMT don sanya abubuwan SMT daidai akan farantin solder na PCB.An raba shi zuwa manual da atomatik.

3.Reflow waldi

Reflow ɗin yana ƙunshe da da'ira mai dumama wanda ke dumama iska ko nitrogen zuwa madaidaicin zafin jiki don hura kan allon da'irar da aka riga aka makala a sashin, yana ba da damar solder na bangarorin biyu ya narke da haɗi zuwa uwa.Amfanin wannan tsari shine cewa ana iya sarrafa zafin jiki cikin sauƙi, ana guje wa oxidation yayin walda, kuma farashin masana'anta yana da sauƙin sarrafawa.

4.AOI mai ganowa

Cikakken sunan AOI (Automatic Optic Inspection) shine Binciken gani na atomatik, wanda shine kayan aiki wanda ke gano lahani na gama gari da aka samu a samar da walda bisa ka'idodin gani.AOI sabuwar fasahar gwaji ce mai tasowa, amma ci gaban yana da sauri, masana'antun da yawa sun ƙaddamar da kayan gwajin AOI.Yayin ganowa ta atomatik, injin zai duba PCB ta atomatik ta hanyar kyamara, tattara hoton, kwatanta mahaɗin solder ɗin da aka gwada tare da ingantattun sigogi a cikin ma'ajin bayanai, kuma bincika lahani akan PCB bayan sarrafa hoto, da nunawa/ yiwa alama. lahani ta hanyar nuni ko alamar atomatik don ma'aikatan gyarawa.

5. Pin yankan na'ura don aka gyara

Ana amfani da shi don yankewa da lalata abubuwan haɗin fil.

6. Wave soldering

Wave soldering shine don barin farfajiyar walda ta farantin toshe kai tsaye ta tuntuɓar ruwa mai zafi mai zafi don cimma manufar walda, ruwan ruwan zafi mai zafi don kula da ƙasa mai niyya, kuma ta na'ura ta musamman don yin tin ruwa mai ƙarfi. irin wannan al'amari na igiyar ruwa, wanda ake kira "wave soldering", babban kayan sa shine sandar siyar.

7. Tin murhun

Gabaɗaya, tin tanderu yana nufin yin amfani da walda na lantarki a cikin kayan aikin walda.Don daidaitattun abubuwan haɗin keɓaɓɓun allon walda, mai sauƙin aiki, sauri, ingantaccen aiki, shine babban mataimaki a samarwa da sarrafawa.

8. Injin wanki

Ana amfani dashi don tsaftace allon PCBA da cire ragowar allon bayan walda.

9. Gwajin gwajin ICT

Ana amfani da Gwajin ICT galibi don Gwaji buɗe da'ira, gajeriyar da'ira da walda na duk sassan PCBA ta hanyar tuntuɓar wuraren gwaji na shimfidar PCB.

10. Gwajin gwajin FCT

FCT tana nufin hanyar Gwaji da ke ba da yanayin aiki na kwaikwaya (ciwon zuciya da kaya) don UUT: Unit Under Test, yana ba shi damar yin aiki a cikin jahohin ƙira daban-daban, don samun sigogi na kowace jiha don tabbatar da aikin UUT.A taƙaice, yana nufin cewa UUT yana ɗaukar nauyin da ya dace kuma yana auna ko amsawar fitarwa ta cika buƙatun.

11. Tsawon gwajin tsufa

Akwatin gwajin tsufa na iya gwada allon PCBA a batches.Ana iya gwada allon PCBA tare da matsaloli ta hanyar kwaikwayon aikin mai amfani na dogon lokaci.
