Kuna da shakku, me yasa aluminum substrate ya fi FR-4?
Aluminum pcb yana da aikin sarrafawa mai kyau, yana iya zama sanyi da zafi mai lankwasa, yankan, hakowa da sauran ayyukan sarrafawa, don samar da nau'i-nau'i da nau'i na katako na kewaye. Na'urar kewayawa ta FR4 ta fi dacewa da tsagewa, tsigewa da sauran matsaloli, kuma yana da wuyar sarrafawa. Don haka, galibi ana amfani da substrate na aluminium a cikin samfuran lantarki masu inganci, kamar hasken LED, na'urorin lantarki, kayan wuta da sauran fannoni.
Tabbas, aluminum pcb shima yana da wasu rashin amfani. Saboda karfen sa, farashin aluminium ya fi girma, kuma gabaɗaya ya fi FR4 tsada. Bugu da ƙari, saboda ƙirar aluminum ba ta da sauƙi don haɗawa tare da fil na na'urorin lantarki na yau da kullum, ana buƙatar kulawa ta musamman, irin su ƙarfe, wanda ke ƙara yawan farashin masana'antu. Bugu da ƙari, maɗaukakin rufi na ƙirar aluminum kuma yana buƙatar kulawa ta musamman don tabbatar da aikin watsar da zafi ba tare da rinjayar ingancin watsa siginar ba.
Baya ga bambancin farashin, akwai kuma wasu bambance-bambance tsakanin aluminum pcb da FR4 dangane da aiki da kewayon aikace-aikace.
Da farko dai, kayan aikin aluminum yana da mafi kyawun aikin watsar da zafi, wanda zai iya watsar da zafin da hukumar ke yi da sauri. Wannan ya sa madaidaicin aluminum ya dace sosai don ƙira mai ƙarfi, ƙirar kewaye mai girma, irin su fitilun LED, na'urorin wutar lantarki, da sauransu. zanen kewayawa.
Abu na biyu, ƙarfin ɗaukar nauyin kayan aikin aluminum ya fi girma, wanda ya dace da babban mita da aikace-aikacen kewayawa na yanzu. A cikin ƙirar ƙirar wutar lantarki mai ƙarfi, halin yanzu zai haifar da zafi, kuma haɓakar haɓakar thermal da ingantaccen aikin haɓakar zafi na ƙirar aluminium na iya kawar da zafi yadda ya kamata, don haka tabbatar da aminci da kwanciyar hankali na kewaye. Ƙarfin ɗaukar nauyi na FR4 na yanzu yana da ƙanƙanta kuma bai dace da babban ƙarfi, ƙirar kewayawa mai tsayi ba.
Bugu da kari, aluminum substrate seismic yi shi ma mafi alhẽri daga FR4, zai iya mafi tsayayya inji girgiza da girgiza, don haka a cikin mota, jirgin kasa da sauran filayen lantarki kewaye zane, aluminum substrate kuma an yi amfani da ko'ina. A lokaci guda, da aluminum substrate kuma yana da kyau anti-electromagnetic tsangwama aiki, wanda zai iya yadda ya kamata kare electromagnetic taguwar ruwa da kuma rage kewaye kutsawa.
Gabaɗaya, pcb aluminum yana da mafi kyawun aikin watsawar zafi, ƙarfin ɗaukar nauyi na yanzu, aikin girgizar ƙasa da juriya na tsangwama na lantarki fiye da FR4, kuma ya dace da babban ƙarfin ƙarfi, ƙima da ƙira mai ƙima. FR4 ya dace da ƙirar da'irar lantarki gabaɗaya, kamar wayoyin hannu, kwamfyutoci da sauran samfuran lantarki na mabukaci. Farashin madaidaicin aluminium gabaɗaya ya fi girma, amma don ƙirar da'irar buƙatu mai girma, zaɓin ƙirar aluminium mataki ne mai mahimmanci.
A taƙaice, aluminum pcb da FR4 sun dace da nau'ikan aikace-aikacen kewayawa daban-daban kuma suna da fa'idodi da rashin amfani nasu. Lokacin zabar kayan allon kewayawa, ya zama dole a auna abubuwa daban-daban bisa ga takamaiman yanayin aikace-aikacen da buƙatu don zaɓar mafi dacewa kayan.
