Uma idizayini ye-PCB isiqediwe, sidinga ukuyihlolela zonke izici zephrojekthi.Njengalapho siqeda iphepha lokuhlola sisodwa, kufanele senze ukuhlaziya okulula futhi sihlole zonke izinkinga zalo futhi, ukuze siqinisekise ukuthi ngeke senze iphutha elikhulu ngenxa yobudedengu.Abakhiqizi abalandelayo be-neoden mounter ukuchaza indlela yokuxazulula inkinga ye-PCBA yokucubungula amaphutha wesekethe emfushane ulwazi oluhlobene.
1. Vula i-PCB design kukhompuyutha, inethiwekhi ye-short-circuit ikhanya, bheka ukuthi iyiphi indawo eseduze kakhulu, okungenzeka ukuthi ixhumeke kucezu.Naka ngokukhethekile isifunda esifushane sangaphakathi se-IC.Uma soldering manual, ukuthuthukisa imikhuba emihle:.
2. Ngaphambi kokudayiswa ukuze uhlole ngokubona ibhodi le-PCB kanye, futhi usebenzise i-multimeter ukuhlola amasekhethi angukhiye ( ikakhulukazi ukunikezwa kwamandla kanye nomhlabathi) ukuthi i-short-circuit.
3. Njalo ngemva kokushisela i-chip ukusebenzisa i-multimeter ukukala ukunikezwa kwamandla kanye nomhlabathi ukuthi kukhona isifunda esifushane.
4. Isikhathi sokuhlanganisa sokukhiqiza se-PCBA musa ukujikijela insimbi, ngokujikijela i-solder ezinyaweni ze-chip (ikakhulukazi izingxenye zesitikha setafula), akulula ukuthola isenzakalo se-short-circuit.Thatha ibhodi ukuze usike umugqa (ikakhulukazi ofanele ibhodi lesendlalelo esisodwa / kabili), usike umugqa ngemva kokuba ingxenye ngayinye yamabhulokhi asebenzayo inikezwe amandla, futhi kancane kancane iqedwe.
5. Ukusetshenziswa kwamathuluzi okuhlaziya indawo yesifunda esifushane.
6. I-PCBA chip processing BGA chip, ngenxa yawo wonke amalunga e-solder embozwe yi-chip engabonakali, kanye nebhodi elinezingqimba eziningi (izingqimba ezingaphezu kwezingu-4), ngakho-ke kungcono ukuhlukanisa amandla ekwakhiweni kwe-chip ngayinye, nge ubuhlalu obuzibuthe noma obungu-0 ohm oxhumano lwelanga kagesi, ukuze kube khona amandla okujikeleza okufushane phansi, kunqamule ukutholwa kobuhlalu obuzibuthe, kulula kakhulu ukunquma isizukulwane ku-chip.Ngenxa yobunzima be-BGA soldering, i-welding manual, uma unganakile izobe iseduze nokunikezwa kwamandla kanye nomhlabathi amabhola amabili e-solder afushane.
7. I-welding ye-capacitor yesitika yetafula elincane elincane kufanele iqaphele, ikakhulukazi i-capacitor yokuhlunga amandla (103 noma 104), inombolo enkulu, kulula ukubangela ukunikezwa kwamandla kanye nomhlabathi ufushane.
