ziviso

Silicon nitride ceramic PCB inomiririra kufambira mberi kukuru muhunyanzvi hwe substrate kune masisitimu emagetsi ane simba guru. Sezvo huwandu hwemagetsi huchiramba huchiwedzera mumotokari dzemagetsi, madhiraivha emaindasitiri, uye mashandisirwo esimba rinodzokororwa, zvinodiwa pazvinhu zve circuit board zvawedzera zvakanyanya. Silicon nitride (Si₃N₄) ceramic substrates inotarisana nematambudziko aya kuburikidza nekupisa kwakanyanya, simba remakanika, uye kugadzikana kwekudzivirira, zvichiita kuti kudziya kutarisirwe zvakanaka kwemagetsi echizvarwa chinotevera uye ma inverter emotokari.

Chii chinonzi Silicon Nitride Ceramic PCB?

Silicon nitride ceramic PCB substrates inogadzirwa kubva kusilicon nitride, iyo yepamusoro ceramic zvinhu ine crystalline chimiro chinopa yakasarudzika mechanic uye inodziya zvivakwa. Izvo zvinhu zvinogadzirwa kuburikidza ne-hot-press kana gasi pressure sintering process inogadzira dense, yunifomu substrate ine porosity shoma, zvichikonzera kupisa kwekushisa kunobva ku70 kusvika 90 W/m · K kwekushanda kunoshanda kupisa kubva kune simba semiconductor zvishandiso.

Iyo substrate inowanzo batanidza mhangura yedunhu yakasungwa kuburikidza neDirect Bonded Copper (DBC) kana Active Metal Brazing (AMB) maitiro. Idzi nzira dzesimbi dzesimbi dzinogadzira chisungo chakasimba chesimbi pakati pemhangura yemhangura uye zvedongo substrate pasina zvinoda zvepakati zvekunamira zvinhu, kuchengetedza magetsi ekudzivirira emagetsi apo ichipa yakaderera yekupisa yekupikisa nzira dzekubvisa kupisa kubva kune zvakakosha zvinoriumba.

Silicon Nitride Ceramic PCB vs. Traditional Ceramic Substrates

Kana ikaongororwa zvichipesana netsika dzeceramic substrates, silicon nitride ceramic PCB zvinhu zvinoratidzira hunhu hwakasiyana hwekuita hunovaita kuti vakwanise kukumbira magetsi emagetsi application.

Zvigadziko zvePCB zvesilicon nitride ceramic zvinobatanidza mipata yekushanda pakati pealumina nealuminium nitride . Kunyange zvazvo thermal conductivity iri pakati pezvinhu izvi, silicon nitride inopa simba rakasiyana-siyana reflexural rinosvika 800 MPa. Kusimba uku kwemuchina, pamwe chete nekupisa kwakanyanya, kunoita kuti silicon nitride ceramic PCB dzikwanise kutsungirira kupisa kakawanda uye kushushikana kwemuchina izvo zvingakanganisa dzimwe substrates.

Mabhenefiti Akakosha eSilicon Nitride Ceramic PCB

Silicon nitride ceramic PCB tekinoroji inopa akawanda tekinoroji mabhenefiti anogadzirisa matambudziko akanyanya mumagetsi emagetsi emazuva ano. Iyo yakasarudzika yemidziyo musanganiswa inotangira kubva kune yayo crystalline chimiro uye maitiro ekugadzira, zvichikonzera maitiro ekuita anonyanya kukodzera kune yakakwirira-yakavimbika maapplication. Mechanical uye thermal zvinobatsira zvinosanganisira:

• Simba remagetsi rinoshamisa -Flexural simba padhuze ne800 MPa inopokana nekupisa bhasikoro kushushikana uye inodzivirira kutsemuka kwe substrate panguva yekushanda kwegungano.
• Superior thermal shock resistance - Inomira nekukurumidza kuchinja kwekushisa kubva -55 ° C kusvika 150 ° C pasina kugadzira microcracks kana delamination.
• Yakagadzikana magetsi ekudzivirira -Inochengetedza yakakwira dielectric simba uye yakaderera dielectric inogara pane yakafara tembiricha renji, kudzivirira kuparara kwevoltage mune yakakwira-voltage application.
• Kusimbiswa kwezvakatipoteredza -Inorambira mukuora kwemakemikari uye inochengetedza kugadzikana kwedimensional pasi pekudedera, hunyoro, uye tembiricha yakanyanyisa.

Izvi zvakasanganiswa zvivakwa zvinoita kuti silicon nitride ceramic PCBs ive sarudzo inosarudzika yezvikumbiro inoda kusimba kwemakanika uye kuvimbika kwekupisa pasi pemamiriro ekushanda zvakanyanya.

Dhizaini Mazano eSilicon Nitride Ceramic PCB

Thermal Management Kufunga

Thermal management dhizaini yesilicon nitride ceramic PCB magungano inoda kutarisisa kukora kwemhangura uye dhizaini dhizaini.
