Ngaba uyathandabuza, kutheni i-aluminium substrate ingcono kune-FR-4?
I-Aluminiyam pcb inokusebenza kakuhle kokusebenza, ingabanda kwaye ishushu ukugoba, ukusika, ukugrumba kunye neminye imisebenzi yokucubungula, ukuvelisa iimilo ezahlukeneyo kunye nobukhulu bebhodi yesekethe. Ibhodi yesekethe ye-FR4 ixhomekeke ngakumbi ekuqhekekeni, ukuhluthwa kunye nezinye iingxaki, kwaye kunzima ukuyiqhuba. Ngoko ke, i-aluminium substrate idla ngokusetyenziswa kwiimveliso ze-elektroniki ezisebenza kakhulu, ezifana nezibane ze-LED, i-automotive electronics, izixhobo zombane kunye nezinye iindawo.
kunjalo, aluminiyam pcb kwakhona ezinye ezingeloncedo. Ngenxa ye-substrate yayo yentsimbi, ixabiso le-aluminium substrate liphezulu, kwaye ngokuqhelekileyo libiza kakhulu kune-FR4. Ukongezelela, ngenxa yokuba i-aluminium substrate ayilula ukudibanisa kunye nezikhonkwane zezixhobo zombane eziqhelekileyo, unyango olukhethekileyo, olufana ne-metallization, luyafuneka, oluyandisa iindleko zokuvelisa. Ukongezelela, i-insulation layer ye-aluminium substrate ifuna unyango olukhethekileyo ukuze kuqinisekiswe ukusebenza kokutshatyalaliswa kobushushu ngaphandle kokuchaphazela umgangatho wokuhambisa umqondiso.
Ukongeza kumahluko kwixabiso, kukho kwakhona umahluko phakathi kwe-aluminium pcb kunye ne-FR4 ngokwemigaqo yokusebenza kunye noluhlu lwesicelo.
Okokuqala, i-aluminium substrate inentsebenzo engcono yokutshatyalaliswa kobushushu, enokuthi ikhuphe ngokufanelekileyo ukushisa okwenziwa yibhodi yesiphaluka ngokukhawuleza. Oku kwenza i-substrate ye-aluminium ifaneleke kakhulu kumandla aphezulu, i-high-density yesekethe design, njengezibane ze-LED, iimodyuli zamandla, njl. Ngokwahlukileyo, ukusebenza kokushisa ubushushu be-FR4 buthathaka, kwaye kufanelekile ngakumbi kumandla aphantsi. uyilo lwesekethe.
Okwesibini, umthamo wangoku wokuthwala we-aluminium substrate mkhulu, ofanelekileyo kwi-frequency ephezulu kunye nezicelo zesekethe eziphezulu zangoku. Kuyilo lwesekethe yamandla aphezulu, umsinga uya kuvelisa ukushisa, kunye ne-conductivity ephezulu ye-thermal kunye nokusebenza kakuhle kokutshatyalaliswa kobushushu be-aluminium substrate inokuphelisa ngokufanelekileyo ukushisa, ngaloo ndlela iqinisekisa ukuthembeka kunye nokuzinza kwesiphaluka. Umthamo wangoku wokuthwala we-FR4 uncinci kwaye awufanelekanga kumandla aphezulu, i-high-frequency circuit circuits.
Ukongeza, ukusebenza kwe-aluminiyam ye-seismic ye-aluminiyam ingcono kune-FR4, inokumelana bhetele nomothuko womatshini kunye nokungcangcazela, ngoko ke kwimoto, kuloliwe kunye nezinye iinkalo zoyilo lwesekethe ye-elektroniki, i-aluminium substrate nayo isetyenziswe ngokubanzi. Kwangaxeshanye, i-aluminium substrate ikwanentsebenzo elungileyo yokuchasana nombane, enokukhusela ngokufanelekileyo amaza ombane kunye nokunciphisa ukuphazamiseka kwesekethe.
Ngokubanzi, i-aluminiyam i-pcb inomsebenzi ongcono wokulahla ubushushu, amandla okuthwala ngoku, ukusebenza kwe-seismic kunye nokumelana nokuphazamiseka kwe-electromagnetic kune-FR4, kwaye ifanelekile kumandla aphezulu, ubuninzi obuphezulu kunye noyilo lwesekethe ephezulu. I-FR4 ifanelekile kuyilo lwesekethe ye-elektroniki ngokubanzi, njengeefowuni eziphathwayo, iilaptops kunye nezinye iimveliso zombane zabathengi. Ixabiso le-aluminium substrate liphezulu ngokubanzi, kodwa kuyilo lwesekethe olufunwa kakhulu, ukukhethwa kwe-aluminium substrate kuyinyathelo elibaluleke kakhulu.
Isishwankathelo, i-aluminium pcb kunye ne-FR4 zifanelekile kwiindidi ezahlukeneyo zezicelo zeesekethe kwaye zineenzuzo zabo kunye nokungalunganga. Xa ukhetha izinto zebhodi yesiphaluka, kuyimfuneko ukulinganisa izinto ezahlukeneyo ngokweemeko ezithile zesicelo kunye neemfuno zokukhetha izinto ezifanelekileyo kakhulu.
