Yintoni uvavanyo pcba

Inkqubo yokucubungula i-PCBA patch inzima kakhulu, kuquka inkqubo yokuvelisa ibhodi ye-PCB, ukuthengwa kwecandelo kunye nokuhlolwa, i-SMT patch assembly, i-plug-in ye-DIP, uvavanyo lwe-PCBA kunye nezinye iinkqubo ezibalulekileyo. Phakathi kwabo, uvavanyo lwe-PCBA lelona khonkco lolawulo lomgangatho libaluleke kakhulu kuyo yonke inkqubo yokusetyenzwa kwe-PCBA, emisela ukusebenza kokugqibela kwemveliso. Ngoko ke zithini iifomu zovavanyo PCBA?Yintoni uvavanyo pcba

I-1, uvavanyo lwe-ICT ikakhulu lubandakanya i-circuit on-off, i-voltage kunye nexabiso langoku kunye ne-curve wave, amplitude, ingxolo, njl.

I-2, uvavanyo lwe-FCT kufuneka luqhube ukudubula kweprogram ye-IC, ukulinganisa umsebenzi webhodi ye-PCBA yonke, ukufumana iingxaki kwi-hardware kunye nesofthiwe, kwaye ixhotyiswe nge-patch processing processing fixture kunye ne-rack yokuvavanya.

I-3, uvavanyo lokukhathala luyisampula yebhodi ye-PCBA, kwaye iqhube i-high-frequency kunye nokusebenza kwexesha elide lomsebenzi, ukujonga ukuba ukusilela kwenzeka, gweba ukuba kunokwenzeka ukusilela kuvavanyo, kunye nengxelo yokusebenza kwe-PCBA. ibhodi kwiimveliso ze-elektroniki.

I-4, uvavanyo kwindawo enzima kakhulu kukutyhila ibhodi ye-PCBA kwiqondo lobushushu, ukufuma, ukuhla, ukutshiza, ukungcangcazela kwexabiso elilinganiselweyo, ukufumana iziphumo zovavanyo lweesampulu ezingahleliwe, ukwenzela ukuba ukunyaniseka kwayo yonke ibhodi yePCBA. ibhetshi.

5, uvavanyo ukwaluphala ikakhulu ukuba amandla ibhodi PCBA kunye neemveliso zombane ixesha elide, uyigcine isebenza kwaye ugcine ukuba kukho nakuphi na ukusilela, emva kovavanyo ukwaluphala iimveliso zombane zingathengiswa batches.PCBA inkqubo entsonkothileyo, kwimveliso kwaye inkqubo processing, kusenokubakho iingxaki ezahlukeneyo ngenxa yezixhobo ezingafanelekanga okanye ukusebenza, akanakuqinisekisa ukuba iimveliso eziveliswayo zifanelekile, ngoko ke kuyimfuneko ukwenza uvavanyo lwe-PCB ukuqinisekisa ukuba imveliso nganye ayiyi kuba neengxaki zomgangatho.

Uyivavanya njani i-pcba

PCBA uvavanyo iindlela eziqhelekileyo, kukho ikakhulu ezi zilandelayo:

1. Uvavanyo lwezandla

Uvavanyo lwe-Manual kukuxhomekeka ngokuthe ngqo kumbono wokuvavanya, ngombono kunye nothelekiso ukuqinisekisa ukufakwa kwamacandelo kwi-PCB, obu bugcisa busetyenziswa kakhulu. Nangona kunjalo, inani elikhulu kunye namacandelo amancinci enza le ndlela ingaphantsi kwaye ifaneleke. Ngaphezu koko, ezinye iziphene ezisebenzayo azibonakali lula kwaye ukuqokelela idatha kunzima. Ngale ndlela, iindlela ezininzi zovavanyo lobuchwephesha ziyafuneka.

2, Uhlolo oluzenzekelayo lwaMacho (AOI)

Ukubona okuzenzekelayo, okukwabizwa ngokuba luvavanyo lombono oluzenzekelayo, lwenziwa ngumtshina okhethekileyo, osetyenziswa ngaphambi nangemva kwe-reflux, kwaye i-polarity yamacandelo ingcono. Kulula ukulandela uxilongo yindlela eqhelekileyo, kodwa le ndlela ayilunganga ekuchongeni isiphaluka esifutshane.

I-3, umatshini wokuvavanya inaliti ebhabhayo

Uvavanyo lwenaliti lufumene ukuthandwa kule minyaka imbalwa idlulileyo ngenxa yenkqubela phambili yokuchaneka koomatshini, isantya, kunye nokuthembeka. Ukongezelela, imfuno yangoku yenkqubo yokuvavanya kunye nokuguqulwa ngokukhawuleza kunye ne-jig-free-free efunekayo kwi-Prototype yokuvelisa kunye nokuveliswa kwevolumu ephantsi kwenza uvavanyo lwenaliti endizayo lube lukhetho olungcono.4. Uvavanyo olusebenzayo

Le yindlela yovavanyo yePCB ethile okanye iyunithi ethile, eyenziwa zizixhobo ezikhethekileyo. Kukho iintlobo ezimbini eziphambili zovavanyo olusebenzayo: Uvavanyo lokugqibela lweMveliso kunye ne-Hot Mock-up.

5. I-Manufacturing Defect Analyzer (MDA)

Iinzuzo eziphambili zale ndlela yovavanyo zixabiso eliphantsi langaphambili, iziphumo eziphezulu, kulula ukulandela ukuxilongwa kunye nokukhawuleza okupheleleyo kwesekethe emfutshane kunye novavanyo lwesekethe evulekileyo. Ukungalungi kukuba uvavanyo olusebenzayo alunakwenziwa, kuhlala kungekho nto ikhombisayo, kufuneka kusetyenziswe umzobo, kwaye iindleko zovavanyo ziphezulu.

izixhobo zovavanyo pcba

Izixhobo zovavanyo eziqhelekileyo ze-PCBA zezi: I-ICT tester ye-intanethi, uvavanyo olusebenzayo lwe-FCT kunye novavanyo lokuguga.

1, umvavanyi we-ICT kwi-intanethi

I-ICT ngumvavanyi ozenzekelayo kwi-intanethi, enoluhlu olubanzi lwezicelo kwaye kulula ukuyisebenzisa.
