Ekucubunguleni i-PCBA yezitshalo ezicutshungulwa ngogesi, ibhodi lokukhanya le-PCB lidinga ukudlula izinqubo eziningi ukuze libe ibhodi le-PCBA eliphelele.Kunemishini eminingi ehlukene yokukhiqiza kulo mugqa omude wokucubungula, onquma ngisho namandla okucubungula emboni ye-PCBA.I-ETA elandelayo izokunikeza isingeniso esifushane sezisetshenziswa nemisebenzi yokucubungula kwe-PCBA.
1, iphrinta ye-stencil ye-SMT
Iphrinta ye-stencil ye-SMT ecutshungulwa yi-PCBA ngokuvamile iqukethe ipuleti elilayishwayo, ukunamathisela kwe-solder, ukugqamisa, kanye nebhodi lokudlulisa.Ngokuvamile, ibhodi lesifunda elizophrintwa liqala lilungiswe etafuleni lokumisa indawo, bese kuthi i-solder paste noma ingcina ebomvu iphrintwe kuphedi elihambisanayo ngensimbi enezikhala ngama-scrapers angakwesokunxele nakwesokudla omshini wokunyathelisa, kanye ne-PCB. ngokuvuza okufanayo kufakwa ku-PCB ngesiteshi sokudlulisa.Umshini wokubeka wenza ukubeka okuzenzakalelayo.
2, Khetha bese ubeka umshini (chip mounter)
Umshini wokukhetha nendawo ufakwa kulayini wokukhiqiza we-PCBA ngemva kwephrinta yokunamathisela ye-solder, okuyidivayisi yokubeka ngokunembile izingxenye zokukhweza ngaphezulu kumaphedi e-PCB ngokuhambisa ikhanda lokubeka.
3,Geza kabusha ihhavini(I-SMD Soldering)
Ngaphakathi kwe-ovini yokugeleza kabusha kunesekhethi yokushisisa eshisisa umoya noma i-nitrogen ekushiseni okuphezulu ngokwanele futhi iyivuthele ebhodini elixhunywe engxenyeni, okuvumela i-solder ezinhlangothini zombili zengxenye ukuthi incibilike futhi ibophezele ku-main. ibhodi.Inzuzo yale nqubo ukuthi izinga lokushisa kulula ukulawula, i-oxidation ingagwenywa ngesikhathi senqubo yokudayiswa, futhi izindleko zokukhiqiza ze-PCBA foundry kulula ukulawula.
4, awu
I-AOI iyisisetshenziswa sokuhlola esizenzakalelayo esisekelwe ezimisweni zokubona ukuze kutholwe izinkinga ezivamile okuhlangatshezwana nazo ekukhiqizeni ukushisela.I-AOI iwuhlobo olusha lokuhlola ubuchwepheshe obuvela emhlabeni osafufusa, kodwa luthuthuke ngokushesha.Abakhiqizi abaningi bethule imishini yokuhlola ye-AOI.Uma itholwa ngokuzenzakalelayo, umshini uskena ngokuzenzakalelayo i-PCB ngekhamera, uqoqe izithombe, bese uqhathanisa amalunga e-solder ahlolwe namapharamitha afanelekayo kusizindalwazi.Ngemva kokucutshungulwa kwesithombe, amaphutha ku-PCB ayahlolwa, futhi amaphutha ayavezwa/amakwa ngesibonisi noma izimpawu ezizenzakalelayo.Phuma uzolungiswa ngabasebenzi bezokulungisa.
5, Umshini wokugunda izingxenye
Isetshenziselwa ukusika nokuguqula izingxenye zephini.
I-6, umshini wokunamathisela wamagagasi
Umshini we-Wave soldering uwukwenza i-soldering surface yebhodi ixhumane ngokuqondile ne-high-temperature liquid tin ngezinjongo zokushisela.Ithini eliwuketshezi elinezinga lokushisa eliphezulu ligcina umthambeka, futhi ithini eliwuketshezi lakha into efana negagasi ngezindlela ezikhethekile, ngakho ibizwa ngokuthi "i-wave soldering".Impahla eyinhloko imigoqo ye-solder.
7, Isithando somlilo
Ngokuvamile, i-tin furnace ibhekisela ethuluzini lokushisela elisetshenziswa ku-PCBA welding electronic.
8, Umshini wokuhlanza
Isetshenziselwa ukuhlanza ibhodi PCBA ukususa izinsalela ebhodini soldered.
9, ukulungiswa kokuhlolwa kwe-ICT
Ukuhlolwa kwe-ICT kusetshenziswa kakhulu ukuhlola izindawo zokuhlola zesakhiwo se-PCB yokuxhumana nophenyo ukuze kutholwe isekethe evulekile ye-PCBA, isifunda esifushane, kanye nokusoda kwazo zonke izingxenye.
10, uhlelo lokuhlola lwe-FCT
I-FCT (Ukuhlolwa Okusebenzayo) Ibhekisela ekulingiseni indawo yokusebenza (injabulo nomthwalo) yebhodi eliqondiwe lokuhlola (UUT: Iyunithi Elingaphansi Kokuhlolwa), ukuze lisebenze ezifundeni ezihlukahlukene zedizayini, ukuze kutholwe amapharamitha wesifunda ngasinye. ukuze uqinisekise i-UUT Indlela yokuhlola yomsebenzi omuhle noma omubi.Kalula nje, kuwukulayisha i-UUT ngesikhuthazi esifanele ukukala ukuthi impendulo yokuphumayo iyenelisa yini.
11, Ukuguga test stand
Indawo yokuhlola ukuguga ingavivinya ibhodi le-PCBA ngamaqoqo, futhi ihlole ibhodi le-PCBA eliyinkinga ngokulingisa ukusebenza komsebenzisi isikhathi eside.
