Ngaphansi komkhuba wemishini kagesi edidiyelwe kakhulu, ukuze kuzuzwe imisebenzi eyinkimbinkimbi endaweni encane yebhodi lesifunda, inqubo yokukhiqiza nobuchwepheshe be-PCB (Ibhodi Lesifunda Eliphrintiwe) lithuthuka ngokushesha.Njengemishini ebalulekile yenqubo yezobuchwepheshe, ubuchwepheshe be-PCB bungagcwalisa ngempumelelo izimbobo ngaphakathi kwebhodi lesifunda futhi buthuthukise ikhwalithi nokuthembeka kwebhodi lesifunda.Lesi sihloko sizokwethula ngokuningiliziwe ukuthi kungani i-PCB idinga ukuxhunywa kwe-resin, inhloso kanye nomsebenzi womshini wokuxhuma i-resin, kanye nezici ezibalulekile zokuthi ungakhetha kanjani umshini wokuxhuma we-PCB ofanele.
1. Kungani ibhodi lesifunda le-PCB lidinga izimbobo zepulaki ye-resin?
Phakathi nenqubo yokukhiqiza amabhodi wesifunda aphrintiwe, amanye ama-voids noma izimbobo eziyizimpumputhe zivame ukuvela, futhi lezi ziphambeko zingathinta kakhulu izinga nokuthembeka kwebhodi lesifunda.Ngaphezu kwalokho, nge-miniaturization kanye nokuhlanganiswa okuphezulu kwemikhiqizo ye-elekthronikhi, izidingo zamabhodi esekethe ziya ngokuya zikhuphuka.Ngakho-ke, ukuze kuqedwe lezi ziphambeko futhi kuthuthukiswe ukusebenza nokuthembeka kwamabhodi wesifunda, kufanele kusetshenziswe ubuchwepheshe bomshini wokuxhuma i-resin.
2. Iyini inhloso yomshini wokuxhuma we-PCB webhodi lesifunda?
Ukuxhunywa kwe-resin kuyinqubo yokugcwalisa izinto ze-resin emigodini noma emigodini eyimpumputhe ngaphakathi kwebhodi lesifunda.Ngokuxhuma izimbobo nge-resin, ukusebenza kwemishini, ukusebenza kukagesi nokuthembeka kwebhodi lesifunda kungathuthukiswa, kuyilapho i-oxidation nokugqwala kwamasekethe angaphakathi kungavinjelwa.
3. Ungakhetha kanjani umshini wokuxhuma we-pcb resin hole ofanelekile?
Ukuzivumelanisa nezimo okuqinile: Uma kucatshangelwa izinhlobo ezahlukene zamabhodi wesifunda nosayizi, umshini wokuxhuma imbobo ye-resin ekhethiwe kufanele ube nokuguquguquka okunamandla futhi ukwazi ukuzivumelanisa namabhodi wesifunda anezincazelo ezahlukene.
Ukunemba okuphezulu: Isikhundla nokujula kwezimbobo zokuxhuma i-resin kudinga ukulawulwa ngokunembile, ngakho umshini okhethiwe wokuxhuma i-resin kufanele ube nokunemba okuphezulu ukuze uqinisekise ukuthi umphumela wokugcwalisa uhlangabezana nezidingo.
Ukuthembeka okuphezulu: Ukuze kuqinisekiswe ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo, umshini okhethiwe wokuxhuma i-resin kufanele ube nokuthembeka okuphezulu futhi ukwazi ukuqedela umsebenzi wokugcwalisa ngokuzinzile.
Kulula ukusebenzisa nokunakekela: Umshini wokuxhuma imbobo ye-resin kulula ukusebenza futhi kulula ukuwunakekela, onganciphisa izindleko zokusebenza nobunzima bokulungisa futhi uthuthukise ukusebenza kahle kokukhiqiza.
Intengo enengqondo: Ngokwesisekelo sokuhlangabezana nezidingo zokusebenza nokusebenza, umshini okhethiwe wokuxhuma i-resin kufanele ube nenani elizwakalayo lokunciphisa izindleko zokukhiqiza.
4. Kunconywa umshini wokuxhuma we-resin othomathikhi ngokugcwele!
Ukukhetha umshini wokuxhuma we-resin ofanele kungathuthukisa ngempumelelo ikhwalithi nokuthembeka kwebhodi lesifunda.Sincoma kakhulu kuwo wonke umuntu.Umshini wokuxhuma webhodi lesekethe we-PCB ozenzakalelayo ngokugcwele - umshini wokuxhuma imaski we-solder wesikrini sokuphrinta uyinki/umshini wokuxhuma we-resin, ohlukile kowendabuko we-PCB resistor.Ngomshini we-welding plug hole, awukwazi't kudingeka
