Kwinkqubo PCBA processing zezityalo zombane, ibhodi ukukhanya PCB kufuneka ukuya kwiinkqubo ezininzi ukuba ibe ibhodi PCBA epheleleyo.Kukho izixhobo ezininzi ezahlukeneyo zemveliso kulo mgca wokusetyenzwa omde, ode umisele isakhono sokwenziwa komzi-mveliso wePCBA.Le ETA ilandelayo iya kukunika intshayelelo emfutshane kwizixhobo kunye nemisebenzi yePCBA processing.
1, umshicileli we-stencil we-SMT
Umshicileli we-stencil we-SMT oqhutywe yi-PCBA ngokubanzi uquka ipleyiti yokulayishwa, i-solder paste, i-embossing, kunye nebhodi yothumelo.Ngokuqhelekileyo, ibhodi yesekethe eza kuprintwa iqala igxininiswe kwitafile yokubeka indawo, kwaye emva koko i-solder paste okanye iglue ebomvu iprintwe kwipadi ehambelanayo ngokusebenzisa i-mesh yensimbi ngasekhohlo nasekunene kumatshini wokushicilela, kunye nePCB. ngokuvuza okufanayo igalelo kwi-PCB ngesikhululo sothumelo.Umatshini wokubeka wenza ukubeka ngokuzenzekelayo.
2, Khetha kwaye ubeke umatshini (i-chip mounter)
Umatshini wokukhetha kunye nendawo ubekwe kumgca wemveliso we-PCBA emva komshicileli we-solder paste, esisisixhobo sokubeka ngokuchanekileyo amacandelo e-surface mount kwi-pads ye-PCB ngokuhambisa intloko yokubeka.
3,Hlaziya i-oveni(SMD Soldering)
Ngaphakathi kwi-oven reflow kukho isiphaluka sokufudumeza esifudumeza umoya okanye i-nitrogen kwiqondo lokushisa eliphezulu ngokwaneleyo kwaye ivuthele ebhodini edityaniswe kwicandelo, ivumela i-solder kumacala omabini ecandelo ukuba inyibilike kwaye idibanise kwinqununu. ibhodi.Inzuzo yale nkqubo kukuba ubushushu kulula ukulawula, i-oxidation inokuphetshwa ngexesha lenkqubo yokuthengisela, kunye neendleko zokwenziwa kwe-PCBA Foundry kulula ukuyilawula.
4, AOI
I-AOI sisixhobo sokuhlola esizenzekelayo esisekwe kwimigaqo ye-optical ukubona iziphene eziqhelekileyo ezifunyenwe kwimveliso ye-welding.I-AOI luhlobo olutsha lovavanyo lobuchwephesha oluvela kwihlabathi elitsha, kodwa luphuhliswe ngokukhawuleza.Abavelisi abaninzi bazise izixhobo zovavanyo ze-AOI.Xa ifunyenwe ngokuzenzekelayo, umatshini uhlola ngokuzenzekelayo i-PCB ngekhamera, uqokelela imifanekiso, kwaye uqhathanise amakhonkco e-solder avavanyiwe kunye neeparitha ezifanelekileyo kwiziko ledatha.Emva kokulungiswa komfanekiso, iziphene kwi-PCB ziyajongwa, kwaye iziphene ziboniswa / ziphawulwe ngomboniso okanye iimpawu ezizenzekelayo.Phumani niyokulungiswa ngabasebenzi bolondolozo.
5, Umatshini wokucheba wamacandelo
Isetyenziselwa ukusika kunye nokuguqula amacandelo e-pin.
I-6, umatshini we-Wave soldering
Wave soldering machine ukwenza umphezulu soldering ebhodini uqhagamshelane ngqo nobushushu eliphezulu inkonkxa engamanzi ngeenjongo welding.I-tin yolwelo oluphezulu lobushushu igcina ithambeka, kwaye inkonkxa yolwelo yenza into efana ne-wave-like phenomenon ngeendlela ezikhethekileyo, ke ibizwa ngokuba "yi-wave soldering".Izinto eziphambili ziyimivalo ye-solder.
7, Iziko leTin
Ngokubanzi, iziko letoti libhekisa kwisixhobo sokuwelda esisetyenziswa kwi-PCBA ye-welding electronic.
8, Umatshini wokucoca
Isetyenziselwa ukucoca ibhodi PCBA ukususa intsalela kwibhodi soldered.
I-9, ukulungiswa kovavanyo lwe-ICT
Uvavanyo lwe-ICT lusetyenziswa ikakhulu ukuvavanya amanqaku ovavanyo lwe-probe contact PCB layout ukubona i-open circuit ye-PCBA, i-short circuit, kunye ne-soldering of all parts.
10, Uvavanyo lwe-FCT
FCT (Uvavanyo olusebenzayo) Ibhekisa kulinganiso lwemeko yokusebenza (uchulumanco kunye nomthwalo) yebhodi ekujoliswe kuyo yovavanyo (UUT: Iyunithi ephantsi kovavanyo), ukuze isebenze kwiindawo ezahlukeneyo zoyilo, ukuze ufumane iparameters zelizwe ngalinye. ukuqinisekisa i UUT Indlela yovavanyo yokusebenza okulungileyo okanye okubi.Ukubeka nje, kukulayisha i-UUT kunye ne-stimulus efanelekileyo yokulinganisa ukuba impendulo yokuphuma iyanelisa.
11, Ukuguga test stand
Ukuma test yokuguga unokuvavanya ibhodi PCBA kwiibhetshi, kwaye ukuvavanya ibhodi PCBA ingxaki ngokulinganisa ukusebenza komsebenzisi ixesha elide.
