Yiziphi izinhlobo zezinhlelo zokusebenza ezivame ukusetshenziswa kuma-PCB e-Heavy Copper?
Ama-PCB ethusi elisindayo afaneleka kakhulu emishinini enamandla amakhulu, ezimotweni, ezisetshenziswa kwezokuvikela nasezempi, kumadivayisi ezokwelapha, nakwezinye izindawo eziningi.
Iyini i-PCB yethusi esindayo?
I-PCB yethusi esindayo ibhekisela kwi-PCB lapho ithusi elingu-3oz noma ngaphezulu lisetshenziswa kuzo zonke izendlalelo zebhodi kokubili izendlalelo zangaphakathi nezangaphandle
Ingabe kukhona imikhawulo yokusebenzisa ithusi elisindayo kuma-PCB anezingqimba eziningi?
Nakuba ithusi elisindayo lingasetshenziswa kuma-PCB anezingqimba eziningi, kunemikhawulo ethile. Ubukhulu bethusi obukhuphukile bungenza kube nzima ukufeza ukubhaliswa okuhle phakathi kwezingqimba. Ngaphezu kwalokho, ubukhulu bebhodi lonke buyanda kakhulu ngethusi elisindayo ezingqimbeni eziningi, okungathinta izinqubo zokukhiqiza njengokubhoboza nokufaka imigodi edlulayo.
Ingabe ama-PCB ethusi anzima angasetshenziswa ngobuchwepheshe bokufaka izinto eziphezu komhlaba (SMT)?
Yebo, ama-PCB ethusi elisindayo angaklanyelwa izingxenye ze-SMT. Kodwa-ke, kudingeka izinto ezikhethekile ezicatshangelwayo ekusetshenzisweni kokunamathisela i-solder, ukubekwa kwezingxenye, kanye namaphrofayili okugeleza kabusha ngenxa yokwanda kwesisindo sokushisa kwezingqimba zethusi elisindayo. Izingxenye ze-SMT eziqondile zingadinga ukujiya okujwayelekile kwethusi ezindaweni zazo zokufaka.
Yini ebhekwa njenge "ithusi elisindayo" ekukhiqizweni kwe-PCB?
Ngokuvamile, noma yikuphi ukujiya kwethusi okungaphezu kwama-3 oz (105 µm) kubhekwa njengethusi elisindayo. Kodwa-ke, incazelo ingahluka kuye ngokusetshenziswa kanye nomkhakha. Abanye abakhiqizi bangase bacabangele ama-3 oz njengendawo yokuqala yethusi elisindayo, kanti abanye bangase babeke umkhawulo ku-4 oz noma ngaphezulu.
Izindleko zama-PCB ethusi anzima ziqhathaniswa kanjani nama-PCB ajwayelekile?
Ama-PCB ethusi elisindayo ngokuvamile abiza kakhulu kunama-PCB ajwayelekile ngenxa yezici eziningana: Izindleko zokukhiqiza ezikhulayo (ithusi eliningi) Izikhathi zokucubungula ezinde, ikakhulukazi zokuqopha Ukuguga okuphezulu kwamathuluzi ngesikhathi sokukhiqiza Izinqubo zokukhiqiza eziyinkimbinkimbi kakhulu Isivuno esingahle sibe siphansi ngenxa yokubekezelelana kokukhiqiza okuqinile Kodwa-ke, izindleko ezikhulayo zingase zincishiswe ukusebenza okuthuthukisiwe, ukuthembeka, kanye nethuba lokunciphisa inani lezingqimba kweminye imiklamo.
Ukhetha kanjani ubukhulu bethusi le-PCB?
Ngokwezindlela ezahlukene zokusebenzisa i-PCB, ubukhulu bethusi obudingekayo buhlukile. Njengama-PCB emikhiqizo yabathengi kanye neyokuxhumana ejwayelekile, ubukhulu bethusi obungu-0.5oz, 1oz, kanye no-2oz buyadingeka; emikhiqizweni kagesi ephethe amandla kagesi aphezulu, njengemikhiqizo enamandla kagesi aphezulu, amabhodi kagesi, neminye imikhiqizo, ama-PCB ngokuvamile adinga ngaphezu kuka-3oz wethusi obukhulu. Ngamafuphi, khetha ubukhulu bethusi obufanele ngokwezidingo zomkhiqizo.
Zingaki izendlalelo zethusi eziku-PCB?
Kukhona ungqimba olulodwa lwethusi ku-PCB enezinhlangothi ezimbili. Kunezingqimba ezimbili zethusi ku-PCB enezinhlangothi ezimbili. Kunezingqimba ezingaphezu kwezimbili zethusi ku-PCB enezingqimba eziningi. Isibonelo, kunezingqimba ezine zethusi ku-PCB enezingqimba ezine.
Ingabe ukhona umehluko phakathi kwebhodi lesifunda lethusi elisindayo nama-PCB ethusi ajiyile?
Akukho mehluko phakathi kwala magama amabili, konke kusho amabhodi wesekethe aphrintiwe anobukhulu bethusi obungu-3oz noma obukhulu. Amabhodi ethusi amakhulu noma ethusi asetshenziswa kabanzi emabhodini kagesi anamandla aphezulu.
Iyini isisindo sethusi esivamile sama-PCB ethusi elinzima?
Isisindo sethusi esivamile sama-PCB ethusi asindayo singaphezu kwama-ounces angu-2 (70um). Kodwa singakhiqiza futhi ukujiya kwethusi okuphezulu njenge-PCB yethusi engu-4 oz, i-PCB yethusi engu-10 oz kanye ne-PCB yethusi efika ku-20 oz.
Yiziphi izinto ezisetshenziswa kuma-PCB e-Heavy Copper?
Ithusi le-RTF kufanele lisetshenziswe.
Izinto zokugcwalisa ezingcono ekugcotshweni kwelamination
Izingxenye ezisebenza ngokushisa okuphezulu
Ingabe kukhona okucatshangelwayo ngokuklama lapho usebenza nama-PCB e-Heavy Copper?
Shaja indawo enkulu yethusi ezindaweni zethusi
Gcina ithusi elisele elifanele

Ukuthembeka okuphezulu
Ukumelana kakhulu nokushisa, ukubanda, kanye nokugqwala
Umjikelezo wokuphila isikhathi eside
Ingabe ibhodi lesifunda eliprintiwe lethusi elisindayo elingu-2oz PCB?
Ku-Richfulljoy, amabhodi wesekethe aphrintiwe anobukhulu obujwayelekile bethusi. Ngakho-ke sicabanga ukuthi i-PCB engu-2oz akuyona ibhodi yesekethe yethusi esindayo, futhi sibheka ama-PCB anobukhulu bethusi obungu-3oz noma ngaphezulu njengamabhodi ethusi esindayo.
