1. Flux kuwotcherera mfundo
Flux imatha kunyamula mphamvu yowotcherera, chifukwa maatomu achitsulo amakhala pafupi wina ndi mnzake pambuyo pakufalikira, kusungunuka, kulowa mkati ndi zina.Kuwonjezera pa kufunika kukumana kuchotsa oxides ndi zoipitsa mu kutsegula ntchito, komanso kukumana sanali dzimbiri, kutchinjiriza, kukana chinyezi, bata, kuipa, chiyero ndi zina zofunika.Nthawi zambiri, zigawo zake zazikulu ndizomwe zimagwiritsidwa ntchito, filimu - kupanga zinthu, zowonjezera, zosungunulira ndi zina zotero.
2. Chotsani okusayidi pamwamba pa chitsulo chosungunuka
M'malo abwinobwino am'mlengalenga, nthawi zambiri pamakhala ma oxides pamwamba pazitsulo zowotcherera.Ma oxides awa adzakhala ndi vuto linalake pakunyowetsa kwa solder panthawi yowotcherera, zomwe zingakhudze njira yowotcherera ndi zotsatira zowotcherera.Choncho, flux ayenera athe kuchepetsa okusayidi, ndi kuwotcherera PCBA processing akhoza kuchitidwa bwinobwino.
3. Pewani makutidwe ndi okosijeni achiwiri
Mu kuwotcherera ndondomeko PCBA processing, Kutentha chofunika.Komabe, pakuwotha, kutulutsa okosijeni mwachangu kudzachitika pamwamba pazitsulo chifukwa cha kuchuluka kwa kutentha.Panthawi imeneyi, flux imafunika kuti iteteze kutsekemera kwachiwiri.
4. Kuchepetsa mphamvu ya solder yosungunuka
Chifukwa cha mawonekedwe a thupi, chitsulo chosungunuka cha solder chidzakhala ndi zovuta zina, ndipo kuthamanga kwapamwamba kudzatsogolera ku liwiro la solder kupita kumalo otsekemera kuti akhudze kunyowetsa bwino mu ndondomeko yowotcherera, ndi ntchito ya flux pa izi. nthawi ndi kuchepetsa mavuto padziko la solder madzi, kuti wettability akhoza kwambiri bwino.
