Kwiinkonzo zendibano ye-PCB enye-stop, imiba emininzi ibandakanyeka, njengemveliso ye-PCB, ukuthengwa kwecandelo, indibano yesekethe eprintiweyo, uvavanyo, njl.njl. Ngeemfuno eziphezulu zezakhono zokuvelisa ezibhityileyo zeemveliso zombane, iimfuno eziphezulu zokuvelisa amandla.Abavelisi bendibano ye-elektroniki kufuneka bahlawule ngakumbi kulawulo lomgangatho wokusetyenzwa kwe-PCBA.I-PCBFuture ikwazisa kumanqaku aphambili e-PCBA yolawulo lomgangatho wokwenziwa kombane.
Inqaku eliphambili 1: Ukuveliswa kwePCB
Zininzi izinto ezimisela umgangatho we-PCB, phakathi kwezixhobo ze-substrate, ulawulo lwemveliso, kunye nobukhulu bobhedu zezona zibalulekileyo.Xa ukhetha ifektri ye-PCB, akufanele unikele ingqalelo kuphela kwixabiso layo, kodwa kwakhona ingqalelo kula manqaku aphambili asemgangathweni.Amabanga ezinto eziphantsi komhlaba asuka ku-A ukuya ku-C, kwaye amaxabiso ahluka kakhulu.Ulawulo olupheleleyo lomgangatho kunye neenkonzo zobugcisa zobugcisa ziya kuba nempembelelo enkulu kumgangatho wePCB.
Inqaku eliphambili 2: Ukuthengwa kwamacandelo
Qinisekisa ukuba amacandelo avela kwi-brand yokuqala, eyona nto ingundoqo kwinkqubo yokupakisha, enokuthintela iziphene zebhetshi kumthombo.Umvelisi wendibano ye-elektroniki kufuneka amise izikhundla zokuhlola izinto ezingenayo (IQC, Ukulawulwa koBulunga obungenayo), khangela ukuhambelana kwezinto ezingenayo, kunye nesampula imbonakalo, ixabiso lecandelo, iimpazamo, njl. .
Inqaku eliphambili lesithathu: inkqubo yokunyuka komphezulu
Kwinkqubo ye-SMT chip processing surface Mount, iinkampani ze-PCBA zokuvelisa i-electronics kufuneka ziqinisekise ukufana kunye nokuhambelana koshicilelo lwe-solder paste, ukucwangciswa okufanelekileyo koomatshini be-SMT, kunye nokuqinisekisa ukuchaneka okuphezulu kwe-IC kunye ne-BGA yokubeka isivuno.Ukuhlolwa kwe-100% ye-AOI kunye nokuhlolwa komgangatho wenkqubo yokuvelisa (IPQC, Ukulawulwa koBulunga beNkqubo) kuyimfuneko kakhulu.Ngexesha elifanayo, kuyimfuneko ukomeleza ulawulo lokuhlolwa kwemveliso egqityiweyo.
Inqaku eliphambili 4: uvavanyo lwePCBA
Iinjineli zoyilo zigcina amanqaku ovavanyo ngokubanzi kwi-PCB kwaye zibonelele ngezicwangciso zovavanyo ezihambelanayo kwi-PCBA esebenza ngabavelisi bezinto zombane.Kwiimvavanyo ze-ICT kunye ne-FCT, i-voltage yesiphaluka kunye nee-curves zangoku zihlalutywa, kunye neziphumo zeemvavanyo zemveliso ye-elektroniki (mhlawumbi kunye nezinye izakhelo zovavanyo) , kwaye ke izicwangciso zovavanyo zifaniswa ukuseka ikhefu lokwamkelwa, elikwafanelekile. ukuze abathengi baqhubeke nokuphucula.
Inqaku eliphambili lesihlanu: ulawulo lwabantu
Kwiinkampani ezenza i-elektroniki ze-PCBA, izixhobo eziphucukileyo ezikumgangatho ophezulu ziyinxalenye encinci nje, kwaye eyona nto ibalulekileyo kulawulo lomntu.Okona kubalulekileyo kukuba abasebenzi bolawulo lwemveliso baqulunqe iinkqubo zolawulo lwemveliso yenzululwazi kwaye babeke iliso ekuphunyezweni kwesikhululo ngasinye.
Kukhuphiswano oluqatha lwemarike, iinkampani zokuvelisa i-elektroniki ziyaqhubeka nokwandisa amandla azo angaphakathi kwaye zicokise ulawulo lwabo lwemveliso sisitshixo sokuziqhelanisa ngokuqhubekayo nemarike.Ulawulo lomgangatho wokwenziwa kwemveliso kunye nenkonzo ngokuqinisekileyo iya kuba yeyona nto iphambili kukhuphiswano.
