I-PCBA yolawulo lweshishini ibhekisa kwibhodi yesekethe eprintiweyo esetyenziswa kwinkqubo yolawulo lweshishini, enokuqonda ulawulo lwedatha kunye nokuhanjiswa komqondiso wezixhobo zolawulo lwamashishini.Ezi PCBA zidla ngokufuna ukuthembeka okuphezulu kunye nokuzinza, kuba nakuphi na ukungazinzi kunokuba nefuthe elibi kumgca wemveliso.
Nazi ezinye iimodeli zePCBA ezisetyenziswa ngokubanzi kulawulo lwamashishini:
PCBA esekelwe FR-4 izinto
Le yi-PCBA yolawulo lwemizi-mveliso esetyenziswa ngokuqhelekileyo.Izinto ze-FR-4 zineenzuzo zamandla aphezulu, ukumelana nomlilo okulungileyo, kunye nokumelana nokushisa okuphezulu.Ukongeza, ukusebenza kwe-insulation kunye nekhono lokuchasana nokubola kwenza kube lukhetho oluhle kakhulu.
PCBA esekelwe substrates metal
Amandla aphezulu kunye nesantya sothumelo zidla ngokufuneka kwizixhobo zolawulo lwamashishini, ngoko ke i-metal substrate PCBA ibe lukhetho oluluncedo kakhulu.I-Aluminiyam okanye ubhedu, njengesixhobo seplate yesiseko, inamandla abalaseleyo okuphelisa ubushushu, i-thermal conductivity ephezulu kunye nokuzinza okuphezulu kobushushu.
I-PCBA ephezulu-echanekileyo
Kwezinye izixhobo zolawulo lwamashishini ezifuna ulawulo oluchanekileyo oluphezulu, i-PCBA ephezulu-echanekileyo lukhetho oluyimfuneko.Iyakwazi ukufezekisa ukuqokelela kweempawu zokulinganisa ukuchaneka okuphezulu kunye nokusebenza kwesignali yedijithali ukuqinisekisa ukuchaneka okuphezulu kunye nokuzinza kwenkqubo yokulawula ishishini.
High-ukuthembeka PCBA
Ukungaphumeleli kwaso nasiphi na isixhobo solawulo lwemizi-mveliso kuya kubangela ubuhle kwaye kunokuba luphazamiseko lomgca wemveliso oyintlekele.Ke ngoko, gxila ekuthembekeni okuphezulu ukuqinisekisa ukuba izixhobo zinokusebenza ixesha elide.(Umzekelo: sebenzisa amacandelo athembeke kakhulu, unikeze uyilo olulungileyo lokulahla ubushushu kunye nomgangatho ophezulu wokuqhuba iteknoloji, njl.njl.)
Isishwankathelo, ukukhetha i-PCBA efanelekileyo kwizixhobo zolawulo lwemizi-mveliso kufuneka ivandlakanywe ngokweemfuno ezahlukeneyo kunye nemisebenzi yezixhobo.
