Nje ukuba uyilo lwePCB lugqityiwe, kufuneka silujonge zonke iimpawu zeprojekthi.Kanye njengaxa siligqiba ngokwethu iphepha lovavanyo, kufuneka senze ucazululo olulula kwaye sijonge zonke iingxaki zalo kwakhona, ukuze siqinisekise ukuba asiyi kwenza mpazamo inkulu ngenxa yokungakhathali.Abavelisi be-neoden mounder balandelayo ukucacisa indlela yokusombulula ingxaki kwi-PCBA ukusetyenzwa kweempazamo zesekethe ezimfutshane ezinxulumene nolwazi.
1. Vula i-PCB idizayini kwikhompyutheni, inethiwekhi ye-short-circuit ilayitiwe, jonga ukuba yeyiphi indawo esondeleyo, eyona nto inokwenzeka ukuba idibanise kwisiqwenga.Nika ingqalelo ekhethekileyo kwi-IC yangaphakathi yesekethe emfutshane.Ukuba i-soldering manual, ukuphuhlisa imikhwa elungileyo:.
2. Ngaphambi kokuba i-soldering ijonge ngokubonakalayo ibhodi ye-PCB kanye, kwaye usebenzise i-multimeter ukujonga iisekethe eziphambili (ingakumbi umbane kunye nomhlaba) nokuba yi-short-circuit.
3. Ngalo lonke ixesha emva kwe-welding chip ukusebenzisa i-multimeter ukulinganisa umbane kunye nomhlaba ukuba kukho isiphaluka esifutshane.
4. PCBA imveliso soldering ixesha musa ukujula intsimbi, ngempazamo fling solder iinyawo chip chip (ingakumbi amacandelo isincamathelisi itheyibhile), akukho lula ukufumana isenzeko elifutshane-yesekethe.Thatha ibhodi ukusika umgca (ngokukodwa ngokufanelekileyo kwibhodi yomaleko enye / kabini), unqumle umgca emva kokuba inxalenye nganye yeebhloko ezisebenzayo zenziwe amandla, kwaye zipheliswe ngokuthe ngcembe.
5. Ukusetyenziswa kwezixhobo zokuhlalutya indawo yesekethe emfutshane.
6. PCBA chip processing BGA chip, ngenxa zonke amalungu solder zigutyungelwe chip engabonakaliyo, kunye nebhodi multi-layer (ngaphezu kwe-4 umaleko), ngoko ke kungcono ukwahlula unikezelo lwamandla kuyilo lwetshiphu nganye, nge i-bead magnetic okanye i-0 ohm uxhulumaniso lwelanga lombane, ukuze kubekho umbane kunye nesiphaluka esifutshane emhlabeni, ukuqhawula ukubhaqwa kwe-magnetic bead, kulula kakhulu ukumisela isizukulwana kwi-chip.Ngenxa yobunzima be-BGA ye-soldering, i-welding manual, ukuba ayilumkanga iya kuba kufuphi nonikezelo lwamandla kunye nomhlaba iibhola ezimbini ze-solder ezimfutshane.
7. Ubungakanani obuncinci betafile yesitikha se-capacitor welding kufuneka silumke, ngakumbi i-capacitor yokucoca amandla ombane (103 okanye 104), inani elikhulu, kulula ukubangela umbane kunye nomhlaba omfutshane.
