Ingabe unokungabaza, kungani i-aluminium substrate ingcono kune-FR-4?
I-Aluminium pcb inokusebenza okuhle kokucubungula, ingabanda futhi igobe ukushisa, ukusika, ukubhoboza neminye imisebenzi yokucubungula, ukukhiqiza ubujamo nobukhulu obuhlukahlukene bebhodi lesifunda. Ibhodi lesifunda le-FR4 lijwayele ukuqhekeka, ukuhlubula nezinye izinkinga, futhi kunzima ukulicubungula. Ngakho-ke, i-aluminium substrate ivame ukusetshenziswa emikhiqizweni ye-elekthronikhi esebenza kahle kakhulu, efana nezibani ze-LED, i-automotive electronics, izinsiza zamandla kanye neminye imikhakha.
Yiqiniso, i-aluminium pcb nayo inezinye izinkinga. Ngenxa ye-substrate yayo yensimbi, intengo ye-aluminium substrate iphezulu, futhi ngokuvamile ibiza kakhulu kune-FR4. Ngaphezu kwalokho, ngenxa yokuthi i-aluminium substrate akulula ukubopha nezikhonkwane zamadivayisi kagesi jikelele, ukwelashwa okukhethekile, okufana ne-metallization, kuyadingeka, okwandisa izindleko zokukhiqiza. Ukwengeza, ungqimba lokufakelwa kwe-aluminium substrate ludinga nokwelashwa okukhethekile ukuze kuqinisekiswe ukusebenza kokukhipha ukushisa ngaphandle kokuthinta ikhwalithi yokudlulisela isignali.
Ngaphezu komehluko wentengo, kukhona futhi umehluko phakathi kwe-aluminium pcb ne-FR4 ngokuya ngokusebenza kanye nebanga lohlelo lokusebenza.
Okokuqala, i-aluminium substrate inokusebenza okungcono kokukhipha ukushisa, okungasusa ngokuphumelelayo ukushisa okukhiqizwa ibhodi lesifunda ngokushesha. Lokhu kwenza i-aluminium substrate ifanelekele kakhulu amandla aphezulu, idizayini yesekethe yokuminyana okuphezulu, njengezibani ze-LED, amamojula wamandla, njll. Ngokuphambene, ukusebenza kokukhipha ukushisa kwe-FR4 akunamandla uma kuqhathaniswa, futhi ifaneleka kakhulu amandla aphansi. umklamo wesifunda.
Okwesibili, umthamo wamanje wokuthwala we-aluminium substrate mkhulu, ofanele imvamisa ephezulu kanye nezinhlelo zokusebenza zesekethe eziphezulu zamanje. Emklamweni wesifunda samandla aphezulu, i-current izokhiqiza ukushisa, kanye ne-conductivity ephezulu ye-thermal kanye nokusebenza okuhle kokushisa kokushisa kwe-aluminium substrate kungaqeda ukushisa ngokuphumelelayo, ngaleyo ndlela kuqinisekiswe ukwethembeka nokuzinza kwesifunda. Umthamo wamanje wokuthwala we-FR4 mncane uma kuqhathaniswa futhi awulungele imiklamo yesekethe yamandla aphezulu, enemvamisa ephezulu.
Ngaphezu kwalokho, ukusebenza kokuzamazama komhlaba kwe-aluminium substrate nakho kungcono kune-FR4, kungamelana kangcono nokushaqeka kwemishini nokudlidliza, ngakho-ke embonini yezimoto, kaloliwe kanye neminye imikhakha yokwakhiwa kwesekethe ye-elekthronikhi, i-aluminium substrate nayo isetshenziswe kabanzi. Ngasikhathi sinye, i-aluminium substrate nayo inokusebenza okuhle kokuphazanyiswa kwe-anti-electromagnetic, okungavikela ngempumelelo amagagasi kagesi futhi kunciphise ukuphazamiseka kwesekethe.
Ngokuvamile, i-aluminium pcb inokusebenza okungcono kokukhipha ukushisa, umthamo wamanje wokuthwala, ukusebenza kokuzamazama komhlaba kanye nokumelana nokuphazanyiswa kukagesi kune-FR4, futhi ifaneleka kumklamo wesekethe wamandla aphezulu, ukuminyana okuphezulu kanye nemvamisa ephezulu. I-FR4 ilungele ukwakhiwa kwesekethe ye-elekthronikhi evamile, njengomakhalekhukhwini, amakhompyutha aphathekayo neminye imikhiqizo kagesi yabathengi. Intengo ye-aluminium substrate ngokuvamile iphakeme, kodwa ngomklamo wesifunda odinga kakhulu, ukukhethwa kwe-aluminium substrate kuyisinyathelo esibaluleke kakhulu.
Kafushane, i-aluminium pcb ne-FR4 zifanele izinhlobo ezahlukene zezinhlelo zokusebenza zesifunda futhi zinezinzuzo zazo kanye nokubi. Lapho ukhetha izinto zebhodi lesifunda, kuyadingeka ukukala izici ezahlukahlukene ngokuya ngezimo ezithile zohlelo lokusebenza kanye nezidingo zokukhetha izinto ezifanele kakhulu.
