I-PCBA yokulawula izimboni ibhekisela ebhodini lesifunda eliphrintiwe elisetshenziswa ohlelweni lokulawula izimboni, elingaqaphela ukulawulwa kwedatha nokudluliswa kwesignali kwemishini yokulawula yezimboni.Lezi PCBA ngokuvamile zidinga ukwethembeka okuphezulu nokuzinza, ngoba noma yikuphi ukungazinzi kungase kube nomthelela omkhulu emugqeni wokukhiqiza.
Nawa amanye amamodeli e-PCBA asetshenziswa kabanzi ekulawuleni izimboni:
I-PCBA esekelwe ezintweni ze-FR-4
Lena i-PCBA yokulawula izimboni evame ukusetshenziswa.Izinto ze-FR-4 zinezinzuzo zamandla aphezulu, ukumelana nomlilo okuhle, nokumelana nokushisa okuphezulu.Ngaphezu kwalokho, ukusebenza kwe-insulation kanye nekhono le-anti-corrosion nakho kukwenza kube ukukhetha okuhle kakhulu.
PCBA esekelwe metal substrates
Amandla aphezulu kanye nesivinini sokudlulisa kuvame ukudingeka emishinini yokulawula yezimboni, ngakho-ke i-PCBA yensimbi engaphansi isibe yisinqumo esiwusizo kakhulu.I-Aluminium noma ithusi, njenge-base plate material, inekhono elihle kakhulu lokulahla ukushisa, ukuqhutshwa kwe-thermal okuphezulu kanye nokuzinza okuphezulu kwezinga lokushisa.
I-PCBA enembayo ephezulu
Kwamanye amadivaysi okulawula izimboni adinga ukulawula ukunemba okuphezulu, i-PCBA enembayo ephezulu iyisinqumo esidingekayo.Ingakwazi ukufeza ukuqoqwa kwesignali yokulingisa ukunemba okuphezulu nokucubungula isignali yedijithali ukuze kuqinisekiswe ukunemba okuphezulu nokuzinza kwenqubo yokulawula izimboni.
I-PCBA enokwethenjelwa okuphezulu
Ukwehluleka kwanoma yiziphi izisetshenziswa zokulawula imboni kuzodala okuhle futhi kungase kube ukuphazamiseka komugqa wokukhiqiza okuyinhlekelele.Ngakho-ke, gxila ekuthembekeni okuphezulu ukuze uqinisekise ukuthi okokusebenza kungasebenza isikhathi eside.(Isibonelo: sebenzisa izingxenye ezithembeke kakhulu, hlinzeka ngomklamo omuhle wokulahla ukushisa kanye nobuchwepheshe bokucubungula obusezingeni eliphezulu, njll.)
Kafushane, ukukhetha i-PCBA efanele imishini yokulawula izimboni kudinga ukuhlolwa ngokwezidingo nemisebenzi ehlukene yemishini.
