(Kupisa-kudzvanywa AlNProduced byWintrustek)
Aluminium nitride (AIN) inozivikanwa nekunaka kwayo yekupisa conductivity uye yakasarudzika magetsi insulating hunhu. Icho chinhu chinowanzoitwa ceramic chinhu chinoshandiswa mumhando dzakasiyana dzemagetsi emagetsi. Aluminium nitride ceramics inoshingirira kusimbi dzakanyungudutswa, kusanganisira mhangura, lithium, nealuminium, pamusoro pekuwedzera kwemafuta uye zvinhu zvinodzivirira magetsi. Aluminium nitridechinhu chinobatsira mukushandiswa kwakasiyana-siyana kwemaindastiri nekuda kwemakemikari ayo uye maitiro ayo.
Nekudaro, mukugadzira, aluminium nitride inonyanya kupatsanurwa kuita mhando mbiri zvichienderana nekuita sintering: pr.essureless sintered aluminium nitride uyeinopisa-yakadzvanywa aluminium nitride. Zvimiro uye mashandisirwo ezvikamu zviviri izvi zvinosiyana zvakanyanya.
Pressureless aluminium nitrideinosanganisa high-purity aluminium nitride powder nediki shoma yekubatsira sintering (yakadai seY2O3), kuumba musanganiswa muchimiro chaidiwa (somuenzaniso, nekuomesa yakaoma kana isostatic pressing), uye wozoipisa pamhepo inopisa (1800 ° C kusvika 2000 ° C) pasi pemhepo inodzivirira inert (nitrogen). Iyi maitiro inovimba nekuita pakati peiyo sintering aid uye alumina iripo pamusoro peiyo AlN masisitimu, ichigadzira chikamu chemvura chinosimudzira kurongeka uye densification yezvimedu.
Features:
Mutengo wakaderera: izvo zvinodiwa zvemidziyo zviri nyore, zvichiita kuti zvikodzere kugadzirwa kwakakura.
Maumbirwo akaomarara: inogona kugadzira akasiyana siyana asina kuumbwa zvikamu uye mahwendefa matete (senge ceramic substrates).
Kuita: kunyangwe ichigona kusangana nezvakawanda zvemaindasitiri, nekuda kwekushaikwa kwekumanikidza kwekunze, ma pores madiki anowanikwa zviri nyore mune izvo zvinhu, uye density kazhinji iri pakati pe97% ne99%.
Main Applications:
Semiconductor packaging substrates (senge LED uye simba module substrates)
Heat sinks uye insulating gaskets
Zvigadzirwa zvisingadziviriri uye zvinodzivirira kupisa
Kupisa-kudzvanywa aluminium nitrideinogadzirwa pachishandiswa nzira yakakosha inonzi hot pressing. Munguva yekupisa-kupisa sintering, unidirectional high pressure yemakumi kana kunyange mazana e megapascals inoshandiswa kune zvinyorwa. Iyi synergistic mhedzisiro yekupisa kwepamusoro uye kudzvanywa kwepamusoro ndiyo kiyi yekuzadzisa kuita kwayo kwakasiyana.
Features:
Kunyanya kuwanda: kumanikidza kunomanikidza kubuda ma pores pakati pezvimedu, zvichikonzera kuwanda kunogona kusvika kune iyo theoretical value (＞99%).
Yakanakisa michina zvivakwa: zvichienzaniswa neyakajairwa sintered AlN, inopisa-yakadzvanywa AlN ine yakakwirira flexural simba uye kuoma.
Yakanakisa thermal conductivity: nekuda kweiyo yakanyanya kuderera porosity, phonon kuparadzira yakaderedzwa, uye yayo yekupisa conductivity inowanzo gadzikana uye iri pedyo nepamusoro muganhu.
Zvinogumira: kudhura kwakanyanya, kuderera kwekugadzirwa kwakanaka, uye kazhinji chete akareruka maumbirwo ejometri senge madhisiki kana mabhuroko anogona kugadziriswa.
Main applications (yepamusoro-yekupedzisira specialized zvinodiwa):
Kupisa kupisa uye kurongedza kweakakwira-simba lasers
Chizvarwa chinotevera chepamusoro-simba density radio frequency/microwave zvishandiso
Kupisa kupisa kwe-ultra-high kuvimbika kwemagetsi masisitimu munzvimbo yeaerospace
Sayenzi yekutsvagisa michina kana mabhenji ekuyedza zvikamu pasi pemamwe mamiriro akanyanya
Unofanira kusarudza sei?
Sarudzaisina pressure aluminium nitridekana: Uri kushanda nemabhodhi emagetsi edunhu (PCBs), masingi ekupisa e LED, kana zvinhu zviri nyore zvemaindasitiri. Pressureless aluminium nitride ndiyo inonyanya kudhura-inoshanda uye yakakura sarudzo.
Sarudzainopisa-yakadzvanywa aluminium nitridekana: Yako nzvimbo yekushandisa iri kudiwa zvakanyanya, senge electrostatic chucks (ESCs) yesemiconductor etching midziyo, yakakwirira-inoshanda laser mabhesi, kana chaiyo zvimiro zvemukati zvinoda kushingirira kushushikana kwemagetsi. Iyo density uye simba mabhenefiti ekupisa-akadzvanywa aruminiyamu nitride haidzokerike mune idzi kesi.
