Njengengilazi yefayibha yebhodi, i-aluminium substrate iyinkampani ejwayelekile ye-PCB. Umehluko wukuthi conductivity ezishisayo aluminiyamu substrate lungaphezu kunakunoma ingilazi fibre ibhodi, ngakho-ke lisetshenziswa izingxenye amandla nezinye izikhathi ezithandwa ukushisa, ezifana LED ukukhanyisa, sekuqalile namandla drives.Here, lo  kwaholela aluminium pcb ukutshela ukuthi yini umehluko phakathi kwe-aluminium substrate ne-fiberglass.

Umehluko phakathi kwe-aluminium substrate ne-fiberglass

I-Aluminium vs. i-fiberglass i-fiberglass iyisetshenziswa esisetshenziswa kakhulu kumabhodi wesifunda, njengeshidi le-FR4 elisetshenziswa kakhulu.Kususelwa ku-fiber fiber njenge-substrate, ngemuva kokuthi ubuso bethusi bunanyathiselwe ekwakheni ipuleti egqoke ithusi, ngemuva kochungechunge yokwenza kabusha ukwakha ibhodi lesifunda eliphrintiwe.

Ucwecwe lwethusi lwebhodi lengilazi yefilibhodi lulungiswe ngebhodi yengilazi yefayibha nge-binder, okuvamise ukuba luhlobo lwe-resin. Ibhodi le-fiberglass uqobo livalwe futhi linezici ezithile ezilangabi ilangabi, kepha ukuqhutshwa kwalo okushisayo akulutho kangako. inkinga yokuhanjiswa kokushisa kwe-glass fiber board, ingxenye yezingxenye ezinezidingo zokushabalalisa ukushisa ngokuvamile zamukela indlela yokuqhuba ukushisa ngokusebenzisa izimbobo.Bese kuthi ngokusebenzisa ukushisa okusizayo okusizayo ukushisa ukushisa.

Kepha nge-LED, akukhona ngokuxhumana ngqo nesinki yokushisa ukushabalalisa ukushisa.Uma umgodi usetshenziselwa ukuqhuba ukushisa, umphumela awukude ngokwanele, ngakho-ke i-LED ngokuvamile isebenzisa i-aluminium substrate njengezinto zebhodi lesifunda.

Isakhiwo se-aluminium substrate ngokuyisisekelo sifana naleso sepuleti le-fiberglass, ngaphandle kokuthi i-fiber fiber ishintshwa nge-aluminium.Ngenxa yokuthi i-aluminium uqobo iyasebenza, uma i-aluminium ihlanganiswe ngqo nethusi, izodala isekhethi elifushane. isibopho ku-substrate ye-aluminium ngaphezu kwento ebophayo, kepha futhi njengempahla yokwambathisa phakathi kwepuleti ne-aluminium plate.Ubukhulu besibopho buzoba nomthelela othile ekuvaleni kwepuleti, ukwahlukanisa okuncane kakhulu akukuhle, futhi ubukhulu buzothinta ukuqhutshwa kokushisa.

Ukuthi i-aluminium substrate yesibani se-LED iqhuba kanjani

Njengoba kungabonakala ekwakhiweni kwe-aluminium substrate engenhla, yize okokusebenza kwe-aluminium kuqhuba, ukwahlukanisa phakathi kwento yethusi ne-aluminium kwenziwa nge-resin.Ngakho-ke, ucwecwe lwethusi ngaphambili lusetshenziswa njengesifunda esiqhubayo, kanti i-aluminium ngemuva isetshenziswa njengempahla yokuhambisa ukushisa, ngakho-ke ayixhunywanga nefoyili yethusi ngaphambili.

I-aluminium ifakwe ngocingo lwethusi nge-resin, kepha ine-voltage range.Ngaphezu kwe-substrate ye-aluminium, kukhona ukuqhutshwa okuphezulu okushisayo kwe-substrate yethusi, leli puleti lisetshenziswa kakhulu kuzakhi zamandla kagesi, izindleko zalo ephakeme kakhulu kune-substrate ye-aluminium.

Lokhu okungenhla kuhlelwe futhi kwanyatheliswa abahlinzeki be-pcb ye-LED aluminium substrate. Uma ungaqondi, sicela uxhumane nathi ku- " ymspcb.com ".
