Yiziphi izinhlobo zezinhlelo zokusebenza ezisetshenziswa ama-Heavy Copper PCBs?
Ama-PCB ethusi elisindayo alungele imishini yamandla aphezulu, izimoto, izicelo zokuvikela nezempi, imishini yezokwelapha, nezinye izindawo eziningi.
Iyini i-PCB yethusi esindayo?
I-PCB yethusi esindayo ibhekisela ku-PCB lapho kusetshenziswa khona i-3oz noma ithusi elikhulu kuzo zonke izingqimba zebhodi zombili izingqimba zangaphakathi nezingaphandle.
Ingabe kukhona ukulinganiselwa ekusebenziseni ithusi elisindayo kuma-PCB anezingqimba eziningi?
Ngenkathi ithusi elisindayo lingasetshenziswa kuma-PCB anezingqimba eziningi, kukhona ukulinganiselwa okuthile. Ukuqina kwethusi okwandisiwe kungenza kube inselele ukufeza ukubhaliswa okuhle phakathi kwezingqimba. Ukwengeza, ukushuba kwebhodi sekukonke kukhuphuka kakhulu ngethusi elisindayo ezingqimbeni eziningi, okungaba nomthelela ezinqubweni zokukhiqiza ezifana nokubhola nokucwenga ngezimbobo.
Ingabe ama-PCB ethusi esindayo angasetshenziswa ngobuchwepheshe be-surface mount technology (SMT)?
Yebo, ama-PCB ethusi esindayo angakhelwa izingxenye ze-SMT. Kodwa-ke, ukucatshangelwa okukhethekile kuyadingeka ekusetshenzisweni kokunamathisela kwe-solder, ukubekwa kwengxenye, kanye namaphrofayili agelezayo ngenxa yokwanda kwesisindo sokushisa kwezingqimba zethusi esindayo. Izingxenye ze-SMT ze-Fine-pitch zingadinga ukujiya kwethusi okujwayelekile ezindaweni zazo zokukhweza.
Yini ethathwa ngokuthi "ithusi elisindayo" ekwenzeni i-PCB?
Ngokuvamile, noma yikuphi ukujiya kwethusi okungaphezu kuka-3 oz (105 µm) kuthathwa njengethusi elisindayo. Nokho, incazelo ingahluka kuye ngokuthi isicelo kanye nemboni. Abanye abakhiqizi bangase bacabangele u-3 oz njengendawo yokuqala yethusi elisindayo, kanti abanye bangase bamise umkhawulo ku-4 oz noma ngaphezulu.
Izindleko zama-PCB ethusi esindayo ziqhathaniswa kanjani nama-PCB ajwayelekile?
Ama-PCB ethusi elisindayo ngokuvamile abiza kakhulu kunama-PCB ajwayelekile ngenxa yezinto ezimbalwa: Ukwenyuka kwezindleko zempahla eluhlaza (ithusi elengeziwe) Izikhathi ezinde zokucubungula, ikakhulukazi ukuhlanganisa ukugqokwa kwamathuluzi aphakeme ngesikhathi sokwenziwa Izinqubo zokukhiqiza eziyinkimbinkimbi Isivuno esingenzeka sincane ngenxa yokubekezelelana kokukhiqiza okuqinile izindleko ezikhuphukile zingase zilungiswe ukusebenza okuthuthukisiwe, ukwethembeka, namandla okunciphisa inani lezendlalelo kweminye imiklamo.
Ungakhetha kanjani ubukhulu be-PCB yethusi?
Ngokusho kokusetshenziswa okuhlukile kwe-PCB, ukujiya kwethusi okudingekayo kuhlukile. Njengama-PCB omthengi ojwayelekile kanye nemikhiqizo yokuxhumana, ukujiya kwethusi okungu-0.5oz, 1oz, kanye no-2oz kuyadingeka; emikhiqizweni ye-elekthronikhi ethwala amandla amanje aphezulu, njengemikhiqizo yamandla kagesi, amabhodi okuphakela amandla, neminye imikhiqizo, ama-PCB ngokuvamile adinga ngaphezu kuka-3oz wethusi owugqinsi. Ngamafuphi, khetha ubukhulu bethusi obufanele ngokwezidingo zomkhiqizo.
Zingaki izingqimba zethusi eziku-PCB?
Kukhona ungqimba olulodwa lwethusi ku-PCB enohlangothi olulodwa. Kunezingqimba ezimbili zethusi ku-PCB enamacala amabili. Kunezingqimba ezingaphezu kwezimbili zethusi ku-PCB enezingqimba eziningi. Isibonelo, kunezingqimba ezine zethusi ku-PCB enezingqimba ezi-4.
Ingabe ukhona umehluko phakathi kwebhodi lesifunda lethusi elisindayo nama-PCB ethusi aminyene?
Akukho mehluko phakathi kwala magama womabili, zonke zisho amabhodi esekethe aphrintiwe ane-3oz noma ukujiya kwethusi okukhulu. I-PCB yethusi ewugqinsi noma amabhodi ethusi esindayo asetshenziswa kakhulu kumabhodi e-electronic amandla aphezulu.
Siyini isisindo sethusi esijwayelekile sama-PCB we-Heavy Copper?
Isisindo sethusi esijwayelekile sama-PCB ethusi esindayo singaphezu kwama-ounces ama-2 (70um). Kodwa futhi singakhiqiza ukujiya okuphezulu kwethusi okufana ne-4 oz yethusi PCB, i-PCB yethusi eyi-10 oz kanye ne-PCB yethusi efinyelela ku-20 oz.
Yiziphi izinto ezisetshenziswa kuma-PCB e-Heavy Copper?
I-RTF yethusi kufanele isetshenziswe.
Izinto ezingcono zokugcwalisa ku-lamination
Ama-substrates aphezulu we-thermal conductivity
Ingabe kukhona ukucatshangelwa kwedizayini lapho usebenza nama-PCB Heavy Copper?
Shaja indawo enkulu yethusi ibe izindawo zethusi
Gcina ithusi elisele elifanele
Khulisa ububanzi bokulandelela kanye nesikhala
Lungiselela ukwakheka kwephedi yesendlalelo sangaphakathi
Yiziphi izinzuzo zokusebenzisa i-Heavy Copper PCBs?
Melana namazanyana amaningi nama-voltage aphezulu
Ukuthembeka okuphezulu
Ikwazi ukumelana nokushisa, ukubanda, nokugqwala
Umbuthano wempilo ende
Ingabe i-2oz yethusi PCB esindayo yethusi ephrintiwe ibhodi lesifunda?
E-Richfulljoy, amabhodi esekethe aphrintiwe ano-0.33oz, 0.5oz, 1oz kanye no-2oz awugqinsi lwethusi olujwayelekile. Ngakho-ke sicabanga ukuthi i-2oz PCB ayilona ibhodi lesifunda lethusi esindayo, futhi sibheka ama-PCB ano-3oz noma ngaphezulu kogqinsi lwethusi njengamabhodi ethusi asindayo.
