Ukulungisa nokunakekela
55. Ungalungisa kanjani umonakalo wendawo wezingubo ze-PCBA?
Hlanza indawo eyonakele nge-ethyl acetate, uhlanze kabusha, bese uxubha/ukhipha ukuze kulungiswe ungqimba, bese ulungisa ngokwezindinganiso.
56. Ungahlola kanjani ikhwalithi yezinto ezilungisiwe?
Hlola ukubukeka, ukujiya, ukunamathela (ukuhlolwa okunqunyiwe), kanye nokumelana nokushisa ukuze uqinisekise ukuthi i-coating yayo iyafana ne-coating yokuqala.
57. Ingabe izimbozo ezindala zingaphinde zimbozwe?
Uma i-substrate kanye nezingxenye zisesimweni esihle, susa i-coating endala ngamakhemikhali/ngomshini bese uyigcoba kabusha, uqaphele ukugwema ukulimala kwebhodi lesifunda.
58. Ungayigcina kanjani i-PCBA ngezimbozo ezimboziwe?
Gwema ukuklwebha, hlola njalo ukubukeka, lungisa umonakalo ngokushesha, bese ugcina ezindaweni ezomile, ezingaboliyo ngegesi.
59. Ungabhekana kanjani nokwehla kokusebenza kwezimbozo ngesikhathi sokusetshenziswa?
Hlaziya izimbangela (isb., ukuguga kwemvelo). Izinkinga zendawo zingalungiswa; ukonakala okukhulu kudinga ukuhlolwa kokufakwa kabusha noma ukushintshwa kwe-PCBA.
60. Ungakuvimbela kanjani ukulimala kwesibili kwe-PCBA ngesikhathi sokulungiswa?
Sebenzisa amathuluzi alwa nokungaguquguquki, lawula umthamo wezinto zokuhlanza, futhi uchaze ngokunembile ububanzi bokumboza ukulungisa ukuze uvimbele ukungcoliswa kwendawo okungavikeli.
61. Ungazilawula kanjani izindleko zokulungisa upende?
Sebenzisa ukulungiswa kwendawo esikhundleni sokufaka kabusha yonke indawo, sebenzisa izinto ezisele ngokuhlakanipha, futhi uthuthukise izinqubo ukuze unciphise isikhathi somsebenzi.
Ubuchwepheshe obusha kanye nezitayela zesikhathi esizayo
62. Yiziphi izinzuzo zokusetshenziswa kobuchwepheshe be-nanocoating ekumbozweni kwemvelo kwe-PCBA?
Ubukhulu buyi-1/10-1/5 kuphela yezembozo zendabuko (5-20μm), enokumelana nokuguguleka okuthuthukisiwe kathathu, ukumelana nokugqwala okuthuthukisiwe ngo-50%, kanye nokuqina okusheshayo.
63. Iyini ithonya lenqubo yokumboza nge-3D ekuvikelweni kwe-PCBA?
Ivumela ukumbozwa kwendawo okuqondile okwenziwe ngokwezifiso, ihlangabezana nezidingo zokuvikela izakhiwo eziyinkimbinkimbi, inciphisa imfucuza yezinto ezibonakalayo, futhi ithuthukisa ukuguquguquka kokukhiqiza.
64. Iyini indlela yokuthuthukiswa kwezimbozo ezihlakaniphile ku-PCBA?
