Yintoni ibhodi ye-aluminium
Ibhodi ye-aluminiyam luhlobo lwebhodi enentsimbi esekwe ngobhedu enomsebenzi olungileyo wokuphelisa ubushushu.Ngokubanzi, iphaneli enye yenziwe ngamaleko amathathu, angamaleko esekethe (ifoyile yobhedu), i-insulation layer kunye ne-metal base layer.Kuqhelekileyo kwiimveliso zokukhanyisa i-LED.Kukho amacala amabini, elinye icala elimhlophe lidityaniselwe iphini le-led, elinye icala ngumbala we-aluminiyam, ngokubanzi liya kugqunywa ngentlama yokuqhuba ubushushu kunye nokunxibelelana nenxalenye yokuqhuba ubushushu.Kukho kwakhona ibhodi ye-ceramic kunye nokunye.
Yintoni iPCB
Ibhodi yePCB ibhekisa ngokubanzi kwibhodi yesekethe eprintiweyo.I-PCB (ibhodi yePCB), eyaziwa ngokuba yi-PCB, ngumboneleli woqhagamshelo lombane lwamalungu e-elektroniki.Sele iphuhla ngaphezu kweminyaka eyi-100;Uyilo lwayo ikakhulu uyilo loyilo;Inzuzo ephambili yokusebenzisa ibhodi yesiphaluka kukunciphisa iimpazamo ze-wiring kunye nendibano kakhulu, kunye nokuphucula inqanaba lokuzenzekelayo kunye nesantya somsebenzi wemveliso.
Ngokwenani leengqimba zeebhodi zesekethe, inokwahlulwa ibe yiphaneli enye, ibhodi enamacala amabini, ibhodi enemigangatho emine, ibhodi enemigangatho emithandathu kunye nezinye iibhodi zeesekethe ezininzi.Ekubeni ibhodi yesekethe eprintiweyo ayiyona imveliso yokuphela ngokubanzi, ibhideke kancinane kwinkcazo yegama.Umzekelo, i-motherboard yekhompyuter yakho ibizwa ngokuba yi-motherboard, kodwa ayibizwa ngokuthe ngqo kwibhodi yesekethe.Nangona kukho iibhodi zeesekethe kwibhodi ephambili, ayifani, ngoko akuyomfuneko ukuthetha okufanayo xa uvavanya ishishini.Ngokomzekelo, ngenxa yokuba kukho iinxalenye ze-IC ezilayishwe kwibhodi yesiphaluka, amajelo eendaba ambiza ngokuba yi-IC board, kodwa eneneni, akalingani nebhodi yesiphaluka eprintiweyo.Ngokuqhelekileyo sibhekisela kwibhodi yesekethe eprintiweyo njengebhodi engenanto - oko kukuthi, ibhodi yesekethe ngaphandle kwento ephezulu.
Umahluko phakathi kwebhodi aluminiyam kunye nebhodi PCB
Kwamanye amaqabane amancinci asanda kuzibandakanya kwishishini lebhodi ye-aluminium, kuya kuhlala kukho umbuzo onjalo.Oko kukuthi, yintoni umahluko phakathi kwebhodi aluminiyam kunye nebhodi PCB.Kulo mbuzo, icandelo elilandelayo liza kukuxelela kanye ukuba yeyiphi na umahluko phakathi kwezi zimbini?
ibhodi PCB kunye nebhodi aluminiyam ziyilelwe ngokweemfuno PCB.Okwangoku, ibhodi ye-PCB esekwe kwi-aluminiyam kwimarike ngokuqhelekileyo ibhodi ye-aluminium enecala elinye.Ibhodi yePCB luhlobo olukhulu, ibhodi ye-aluminiyam luhlobo olunye lwebhodi yePCB, iyipleyiti yesinyithi esekwe kwi-aluminium.Ngenxa yokuqhuba kakuhle kwe-thermal, isetyenziswa ngokubanzi kwishishini le-LED.
Ibhodi yePCB ibhodi yobhedu ngokubanzi, ekwahlulwe yaba yiphaneli enye kunye nebhodi enamacala amabini.Izinto ezisetyenzisiweyo phakathi kwezi zimbini zihluke kakhulu.Izinto eziphambili zebhodi ye-aluminium yipleyiti ye-aluminium, kunye neyona nto iphambili yebhodi ye-PCB yobhedu.Ibhodi ye-aluminium ikhethekileyo kwizinto zayo zePP.Ukutshatyalaliswa kobushushu kulungile.Ixabiso likwabiza kakhulu
Xa kuthelekiswa nezi zimbini kubushushu bokutshatyalaliswa, ukusebenza kwebhodi ye-aluminiyam ekutshitshiseni ubushushu kungaphezulu kwebhodi ye-PCB, kunye ne-thermal conductivity yayo yahlukile kwi-PCB, kwaye ixabiso lebhodi ye-aluminium libiza kakhulu.
