Ceramic PCB: sima substrate laupapa matagaluega
Ceramic Substrate o loʻo faʻamatalaina ai se laupapa faʻapitoa faʻapitoa e pipii saʻo ai le pepa alumini kopa i luga o le mea (itu tasi poʻo le itu lua) o le alumina (Al2O3) poʻo le mama alumini nitride (AlN) meaʻai sima i le vevela. Pe a faatusatusa i le tulaga masani FR-4 po o le mama mamafa alumini substrate, o le ultra-thin composite substrate faia e tulaga ese le lelei insulation eletise, conductivity vevela tulaga ese, solderability tulaga ese ma le malosi sootaga maualuga, ma e mafai foi ona togitogia tele ata e pei o le PCB, ma mata'ina gafatia lugging oi ai nei. E fetaui mo mea e maua ai le mafanafana maualuga (LED maualuga-malamalama, malosi o le la), faʻapea foʻi ma le malosi o le tau e teteʻe ai e sili ona lelei i fafo. Ceramic Circuit Board Tekonolosi Folasaga
Aisea e fa'aaoga ai mea fa'amea e gaosia ai laupapa fa'asalalau? O laupapa ta'avale sima e fai i sima fa'aeletonika ma e mafai ona faia i si'i eseese. O uiga o le maualuga o le vevela ma le maualuga o le eletise eletise o laupapa sima e sili ona lauiloa. O le lelei o le maualalo o le dielectric faifai pea ma le dielectric gau, maualuga le vevela conductivity, lelei le mautu kemisi, ma tutusa faʻalauteleina faʻavevela faʻatasi i vaega e taua foi. O le gaosiga o laupapa ta'avale sima o le a fa'aogaina le tekonolosi LAM, o le fa'atekonolosi fa'avavevave le fa'aogaina o le laser. O loʻo faʻaaogaina i totonu o le faʻafanua LED, eletise eletise semiconductor modules, pusaaisa semiconductor, faʻaeletonika faʻaeletonika, taʻavale eletise eletise, eletise eletise eletise, vaega eletise atamai, faʻaogaina o le eletise eletise, faʻamalo-setete relays, taʻavale eletise, fesoʻotaʻiga, aerospace, ma vaega faaeletonika faamiliteli.
Tulaga lelei o le Ceramic PCB
E le pei o le FR-4 masani, o mea sima e lelei le faʻatinoina o le maualuga ma le faʻaogaina o le eletise, e maualuga le faʻauluina o le vevela, faʻamautu vailaʻau, faʻamautu lelei vevela, ma isi mea e le o iai ni mea faʻapitoa. O se mea fou fa'apipi'i lelei mo le fa'atupuina o ta'amilosaga fa'atasi tetele ma fa'aogaina eletise eletise.
Tulaga sili:
maualuga atu le fa'avevelaina o le vevela.
E sili atu fa'atusatusaga fa'alautele fa'amama.
Malosi ma maualalo tete'e u'amea ata alumina ceramic laupapa matagaluega.
O le solderability o le substrate e lelei, ma le faʻaaogaina vevela e maualuga.
Fa'alava lelei.
Maualalo maualuga-aveve leiloa.
Fa'apotopotoga maualuga e mafai.
E le o iai ni mea faʻaola, e faʻasaʻo i ave o le cosmic, e maualuga le faʻatuatuaina i le aerospace, ma e umi lona soifua tautua.
O le 'apa kopa e le oi ai se oxide layer ma e mafai ona fa'aoga mo se taimi umi i se siosiomaga fa'aitiitia. Ceramic PCBs mafai ona aoga ma lelei mo laupapa matagaluega lolomi i nei ma le tele o isi alamanuia, e faalagolago i lou mamanu ma gaosiga manaoga.
Ceramic PCB o se ituaiga o vevela o loʻo faʻatautaia le paʻu pala ma faʻapipiʻi faʻaola, ma o le vevela conduction organic ceramic PCB ua saunia i le conductivity vevela o 9-20W / m. I se isi faaupuga, sima PCB o se laupapa matagaluega lolomi ma mea faavae sima, lea e sili thermally conductive mea e pei o le alumina, alumini nitride, faapea foi le beryllium oxide, lea e mafai ona faia se aafiaga vave i le faaliliuina atu o le vevela mai nofoaga vevela ma le dissipating. i luga o le fogāeleele atoa. O le a le mea e sili atu, o le sima PCB o loʻo faʻapipiʻiina i tekinolosi LAM, o se faʻaogaina vave o le faʻaogaina o tekonolosi. O le mea lea o le sima PCB e maualuga tele e mafai ona faia o le laupapa matagaluega lolomi masani atoa ma se fausaga lavelave itiiti ma le faatinoga faaleleia.
E ese mai i le MCPCB , afai e te manaʻo e faʻaoga le PCB i le maualuga o le mamafa, le maualuga o le insulation, le maualuga o taimi, le maualuga o le vevela, ma le maualuga o le faʻatuatuaina ma le laʻititi o oloa eletise, o le Ceramic PCB o lau filifiliga sili lea.
Aisea e maua ai se faatinoga sili ona lelei le Ceramic PCB? E mafai ona e maua se vaaiga puupuu i lona fausaga faavae ona e malamalama ai lea.
