I-PTR/IR Sensor Printed Circuit Board PCB For Control LED Light

Ukwethulwa kwe-MCPCB

I-MCPCB isifinyezo se-Metal core PCBS, okuhlanganisa i-PCB esekwe ku-aluminium, i-PCB esekwe ethusi kanye ne-PCB esekwe ngensimbi.

Ibhodi elisekelwe ku-aluminium liwuhlobo oluvame kakhulu.Isisekelo sezinto siqukethe i-aluminium core, i-FR4 ejwayelekile nethusi.Ifaka isendlalelo esigqoke esishisayo esichitha ukushisa ngendlela esebenza kahle kakhulu ngenkathi kupholisa izingxenye .Njengamanje, i-Aluminium Based PCB ithathwa njengesixazululo samandla aphezulu.Ibhodi elisekelwe ku-aluminium lingangena esikhundleni sebhodi le-ceramic elithambile, futhi i-aluminium inikeza amandla nokuqina kumkhiqizo izisekelo ze-ceramic ezingakwazi.

I-Copper substrate ingenye yezingxenye zensimbi ezibiza kakhulu, futhi ukuhamba kwayo okushisayo kungcono izikhathi eziningi kune-aluminium substrates kanye ne-iron substrates.Ifaneleka kahle kakhulu ekulahlekeni kokushisa kwamasekhethi aphezulu, izingxenye ezisezifundeni ezinokuhlukahluka okukhulu kwezinga lokushisa eliphezulu neliphansi kanye nemishini yokuxhumana enembile.

Isendlalelo se-thermal insulation singenye yezingxenye eziyinhloko ze-copper substrate, ngakho-ke ubukhulu be-copper foil ngokuvamile bungama-35 m-280 m, okungafinyelela umthamo oqinile wokuthwala okwamanje.Uma kuqhathaniswa ne-aluminium substrate, i-copper substrate ingafinyelela umphumela ongcono wokulahla ukushisa, ukuze kuqinisekiswe ukuzinza komkhiqizo.

Isakhiwo se-Aluminium PCB

Circuit Copper Layer

Isendlalelo sethusi sesifunda siyathuthukiswa futhi siqoshwe ukuze sakhe isifunda esiphrintiwe, i-aluminium substrate ingathwala amandla amanje aphezulu kunokuqina okufanayo kwe-FR-4 kanye nobubanzi bokulandelela okufanayo.

I-Insulating Layer

Isendlalelo se-insulating ubuchwepheshe obuyinhloko be-aluminium substrate, edlala ngokuyinhloko imisebenzi yokufakelwa nokushisa.I-aluminium substrate insulating layer iyisithiyo esikhulu sokushisa esakhiweni semojula yamandla.Ukushisa okungcono kwe-thermal layer ye-insulating, kuphumelela kakhulu ukusabalalisa ukushisa okukhiqizwa ngesikhathi sokusebenza kwedivayisi, kanye nokunciphisa izinga lokushisa kwedivayisi,

I-Metal substrate

Iluphi uhlobo lwensimbi esizolukhetha njenge-substrate yensimbi evikelayo?

Kudingeka sicabangele i-coefficient yokwandisa okushisayo, ukuqhutshwa kwe-thermal, amandla, ubulukhuni, isisindo, isimo esiphezulu kanye nezindleko ze-substrate yensimbi.

Ngokuvamile, i-aluminium ishibhile kakhulu kunethusi.Izinto ezitholakalayo ze-aluminium ziyi-6061, 5052, 1060 nokunye.Uma kunezidingo eziphakeme ze-thermal conductivity, izakhiwo zemishini, izakhiwo zikagesi nezinye izinto ezikhethekile, amapuleti ethusi, amapuleti ensimbi engagqwali, amapuleti ensimbi namapuleti ensimbi ye-silicon angasetshenziswa.
