I-PCBA isho inqubo yokukhweza, ukufakwa kanye nokunamathisela izingxenye ze-PCB ezingenalutho.Inqubo yokukhiqiza ye-PCBA idinga ukudlula uchungechunge lwezinqubo ukuze iqedele ukukhiqiza.Manje, i-PCBFuture izokwethula izinqubo ezihlukahlukene zokukhiqizwa kwe-PCBA.
Inqubo yokukhiqiza ye-PCBA ingahlukaniswa ngezinqubo ezimbalwa ezinkulu, ukucutshungulwa kwesichibi se-SMT→ukucubungula i-plug-in ye-DIP→ukuhlolwa kwe-PCBA→ukuhlanganiswa komkhiqizo oqediwe.
Okokuqala, isixhumanisi sokucubungula isichibi se-SMT
Inqubo yokucutshungulwa kwe-chip ye-SMT yile: ukuxutshwa kwe-solder paste→ ukuphrinta kokunamathisela kwe-solder→SPI→ukukhweza→ukuphinda kufakwe i-solder→AOI→sebenza kabusha
1, ukuxuba unamathisele solder
Ngemuva kokuthi i-solder paste ikhishwe esiqandisini futhi incibilikile, inyakaziswa ngesandla noma ngomshini ukuze ihambisane nokuphrinta nokunamathisela.
2, ukuphrinta kokunamathisela kwe-solder
Faka i-solder paste ku-stencil, bese usebenzisa i-squeegee ukuphrinta unamathisele we-solder kumaphedi e-PCB.
3, SPI
I-SPI ingumtshina we-solder paste ukujiya, okwazi ukubona ukuphrinta kwe-solder unama futhi ulawule umphumela wokuphrinta we-solder unama.
4. Ukukhweza
Izingxenye ze-SMD zibekwe kusiphakeli, futhi ikhanda lomshini wokubeka libeka ngokunembile izingxenye kusiphakeli kumaphedi e-PCB ngokuhlonza.
5. I-Reflow soldering
Dlulisa ibhodi le-PCB eligingqiwe ku-reflow soldering, futhi ukunamathisela okufana nokunamathisela kwe-solder kuyashiswa kube uketshezi ngezinga lokushisa eliphezulu ngaphakathi, futhi ekugcineni kupholiswe futhi kuqiniswe ukuze kuqedelwe ukusoda.
6.AOI
I-AOI iwukuhlola okuzenzakalelayo, okukwazi ukubona umphumela wokushisela webhodi le-PCB ngokuskena, futhi kutholwe amaphutha ebhodi.
7. ukulungisa
Lungisa okungalungile okutholwe yi-AOI noma ukuhlola okwenziwa ngesandla.
Okwesibili, isixhumanisi sokucubungula i-plug-in ye-DIP
Inqubo yokucubungula i-plug-in ye-DIP yilena: ipulaki → i-wave soldering → ukusika unyawo → inqubo yokushisela okuthunyelwe → ibhodi lokuwasha → ukuhlolwa kwekhwalithi
1, i-plug-in
Cubungula izikhonkwane zezinto ze-plug-in bese uwafaka ebhodini le-PCB
2, i-wave soldering
Ibhodi elifakiwe lingaphansi kwe-wave soldering.Kule nqubo, ithini eliwuketshezi lizofuthwa ebhodini le-PCB, futhi ekugcineni lipholiswe ukuze kuqedelwe ukusoda.
3, ukusika izinyawo
Izikhonkwane zebhodi elidayisiwe zinde kakhulu futhi zidinga ukunqunywa.
4, post welding processing
Sebenzisa i-ayina yokunamathisela kagesi ukuze udayise izingxenye.
5. Geza ipuleti
Ngemuva kwe-wave soldering, ibhodi lizoba lingcolile, ngakho-ke udinga ukusebenzisa amanzi okugeza nethangi lokuwasha ukuze ulihlanze, noma usebenzise umshini ukuhlanza.
6, ukuhlolwa kwekhwalithi
Hlola ibhodi le-PCB, imikhiqizo engafanelekile idinga ukulungiswa, futhi imikhiqizo efanelekayo kuphela engangena enqubweni elandelayo.
Okwesithathu, ukuhlolwa kwe-PCBA
Ukuhlolwa kwe-PCBA kungahlukaniswa ngokuhlolwa kwe-ICT, ukuhlolwa kwe-FCT, ukuhlolwa kokuguga, ukuhlolwa kokudlidliza, njll.
Ukuhlolwa kwe-PCBA kuyisivivinyo esikhulu.Ngokwemikhiqizo ehlukene kanye nezidingo ezahlukene zamakhasimende, izindlela zokuhlola ezisetshenziswayo zihlukile.
Okwesine, ukuhlanganiswa komkhiqizo ophelile
Ibhodi le-PCBA elihloliwe liqoqelwa igobolondo, bese lihlolwa, futhi ekugcineni lingathunyelwa.
Ukukhiqizwa kwe-PCBA kuyisixhumanisi esisodwa ngemva kwesinye.Noma iyiphi inkinga kunoma yisiphi isixhumanisi izoba nomthelela omkhulu kakhulu kwikhwalithi iyonke, futhi nokulawulwa okuqinile kwenqubo ngayinye kuyadingeka.
