Ukufika kwama-PCB ahlukahlukene ahlukahlukene
Ngokomlando, amabhodi wesifunda aphrintiwe ngokuyinhloko abonakala ngesakhiwo sawo esinye noma ahlanganiswe kabili, esabeka izingqinamba ekufanelekeni kwazo kwezicelo zemvamisa ephezulu kakhulu ngenxa yokuwohloka kwesiginali kanye nokuphazanyiswa kwe-electromagnetic (EMI). Noma kunjalo, ukwethulwa kwamabhodi wesifunda anemibuthano ephrintiwe kuholele ekuthuthukisweni okuphawulekayo ngobuqotho besiginali, ukungqubuzana kwe-electromagnetic (EMI), kanye nokusebenza okuphelele.
I-PCBS ebekwe ngamanani amaningi (isithombe Lo mklamo unika amandla ukuhanjiswa kwezimpawu kanye nezindiza zamandla ngendlela eyinkimbinkimbi.
Amabhodi wesifunda ahlukahlukene aphrintiwe (ama-PCB) ahlukaniswa abalingani bawo abangashadile noma ababili abaseceleni ngokuba khona kwezingqimba ezintathu noma ngaphezulu ezenziwayo ezihlukaniswe ngezinto ezifakwayo, ezaziwa njengezingqimba ze-dielectric. Ukuxhumeka kwalezi zingqimba kuvuselelwa yi-vias, okuyizindlela zokuphatha ezivuthayo ezenza ukuxhumana phakathi kwezendlalelo ezihlukile. Idizayini eyinkimbinkimbi yama-PCS ahlukahlukene anika amandla okuhlushwa okukhulu kwezakhi kanye nokujikeleza okuyinkimbinkimbi, ebanikeza abalulekile kubuchwepheshe bezwe.
I-PCBS ye-Multilayer imvamisa ibonisa izinga eliphakeme lokuqina ngenxa yenselelo ebonakalayo yokuthola izingqimba eziningi ngaphakathi kwesakhiwo se-PCB eguquguqukayo. Ukuxhumeka kukagesi phakathi kwezendlalelo kusungulwe ngokusebenzisa izinhlobo eziningi ze-Vias (Umdwebo 2), kufaka phakathi izimpumputhe ne-vias ezingcwatshwe.
Ukucushwa kufaka ukubekwa kwezendlalelo ezimbili ebusweni ukusungula ukuxhumana phakathi kwebhodi lokujikeleza eliphrintiwe (PCB) kanye nemvelo yangaphandle. Ngokuvamile, ubuningi bezendlalelo kumabhodi wesifunda aphrintiwe (ama-PCBs) aprintiwe (ama-PCB) aphrintiwe. Lokhu ngokuyinhloko kubangelwa izibalo zezinombolo ezingathandeki ezindabeni ezinjengezimpi.
Inani lezendlalelo ngokujwayelekile liyahlukahluka ngokuya ngohlelo lokusebenza oluthile, ngokujwayelekile lungaphakathi kwezabelo ezine kuya kweziyishumi nambili.
Imvamisa, iningi lezicelo lidinga ubuncane obuncane bezendlalelo eziyisishiyagalombili. Ngokuphambene nalokho, izinhlelo zokusebenza ezifana nama-Smartphones asebenzisa kakhulu ingqikithi yezendlalelo eziyishumi nambili.
Izicelo eziphambili
Ama-PCB ama-multi-ungqimba asetshenziswa ezinhlobonhlobo zezicelo ze-elekthronikhi (Umdwebo 3), kufaka phakathi:
● I-elekthronikhi yabathengi, lapho ama-PCB angqimba ahlukahlukene adlala indima eyisisekelo enikeza amandla adingekayo kanye namasignali ezinhlobonhlobo zemikhiqizo efana nama-Smartphones, amaphilisi, amadivayisi wokugembula. Ama-elekthronikhi amnandi futhi aphathekayo esincike kuwo nsuku zonke abhalwa phansi emklamweni wawo weCompact kanye nesakhi esiphezulu
● Emkhakheni wezokuxhumana ngocingo, ukusetshenziswa kwama-PCs ahlukahlukene ahlukahlukene kusiza ukudluliswa kwezwi, idatha, kanye namasignali wevidiyo kuwo wonke amanethiwekhi aphesheya kwamanethiwekhi, ngaleyo ndlela kuqinisekiswe ukuxhumana okuthembekile nokusebenzayo
● Izinhlelo zokulawula izimboni zincike kumabhodi wesifunda eliphrintiwe ahlukahlukene (ama-PCB) ngenxa yamandla awo okuphatha ngempumelelo amasistimu wokulawula ayinkimbinkimbi, izindlela zokuqapha kanye nezinqubo ezenzakalelayo. Amaphaneli wokulawula umshini, ama-robotic, kanye nezezimboni ezenzakalelayo zincike kubo njengohlelo lwabo oluyisisekelo
● Ama-PC we-Multi-Laner nawo afanelekile kumadivayisi wezokwelapha, ngoba abalulekile ekuqinisekiseni ukunemba, ukwethenjwa, nokuhlangana. Imishini yokuxilonga, amasistimu wokuqapha isiguli, namadivaysi ezokonga impilo athonywa kakhulu yiqhaza lawo elibalulekile.
Izinzuzo Nezinzuzo
Ama-pcbs amaningi ama-PCB ahlinzeka ngezinzuzo nezinzuzo eziningana kuzinhlelo zokusebenza ezivame kakhulu, kufaka phakathi:
● Ukuthuthukisa ukuthembeka kwesiginali Ukuphazanyiswa kwesiginali okuphansi kwamabhodi wesifunda ahlukahlukene aphrintiwe aholela ekusebenzeni okuthuthukile, velocity, kanye nokwethenjwa
● Ukuncishiswa kwe-EMI: Ngokusebenzisa izindiza ezinikezelwe ezinikezelwe kanye nama-PCB ahlinzekwe ngempumelelo i-EMI, ngaleyo ndlela athuthukise ukuthembeka kohlelo futhi anciphise ukuphazanyiswa ngemibuthano engomakhelwane
● I-Compact Design: Ngamandla okuthola izakhi eziningi nezinhlelo eziyinkimbinkimbi zomzila, ama-PC amaningi anikeze amandla amandla okusetshenziswa okuhlanganisiwe, okubalulekile kwezicelo eziphoqelelwa isikhala njengamadivayisi eselula nezinhlelo ze-aerospace.
E-
● Design ukuguquguquka: Ukuguquguquka okuhlukahlukene kwama-PCB ama-Multi-Lared Kuvumela ukuguquguquka okubanzi ukuguquguquka, okunika onjiniyela ukwenza kahle amapharamitha okusebenza anjenge-Imperal ukufana, ukubambezeleka kwamandla.
