Simba MCPCB yeHigh Current uye Thermal Management

Nhanganyaya: Dambudziko reSimba uye Kupisa muMagetsi eMagetsi

Masimba emagetsi masisitimu anotarisana nematambudziko ari kukwira sezvo mainjiniya anosundidzira epamusoro masimba emagetsi uye compact fomu zvinhu. Mota madhiraivha, inverters, uye maindasitiri ekudzora maseketi anogadzira kupisa kwakanyanya uku achiitisa mafungu anogona kudarika zana amperes munzvimbo dzakadzika.

Echinyakare FR4 akadhindwa edunhu mabhodhi anonetsekana pasi peaya mamiriro, aine mashoma ekupisa conductivity kutenderedza 0.3 W/mK uye nzira dzemhangura dzinopisa pasi pekushanda kwakasimba-ikozvino. Izvi zvipimo zvinomanikidza mainjiniya kuti angave akanganisa kusimba kwesimba kana njodzi nguva isati yakwana.

Simba reMCPCB rinobuda semhinduro yakagadzirwa nehunyanzvi kune zvinodiwa zvekupisa nemagetsi. Nekutsiva substrate yemagetsi yakajairika nekuvaka kwakavakirwa nesimbi, mabhodhi aya akasarudzika anopa mashandiro ekupisa ayo maPCB emazuva ano asingakwanise kuenzana nawo uku achichengetedza hunhu hwakakodzera hwesimba remagetsi rinodiwa kuti magetsi aendeswe zvakanaka.

Kunzwisisa Simba MCPCB uye Basa Rayo

Simba reMCPCB rinoshandisa simbi , inowanzo kuve aruminiyamu kana mhangura, sehwaro hwehwaro pasi pemaitiro edunhu. Chivakwa chakajairika chine jira redunhu remhangura rinotangira pamaunzi maviri kusvika matanhatu, jira rekudzivirira kupisa rinofambisa magetsi, uye simbi inoshanda sechinoparadzira kupisa chakabatanidzwa.

Ichi chivakwa chinosiyana zvakanyanya kubva kune akajairwa multilayer mabhodhi uko kupisa kunofanirwa kufamba kuburikidza neakawanda FR4 akaturikidzana ane hurombo hwekupisa zvivakwa. Chigadziko chesimbi chinopa kupisa kwekushisa pakati pe 1.0 ne8.0 W/mK zvichienderana nedielectric material yakasarudzwa, inomiririra kuwedzera kwekuita kwekatatu kusvika makumi maviri neshanu pamusoro peFR4.

Kupfuura mabhenefiti ekupisa, iyo yakaomesesa simbi substrate inopa kugadzikana kwedimensional pasi pekupisa bhasikoro uye michina yekumisikidza masimba anoisirwa ma module emagetsi. Ikozvino-yekutakura kugona kunowedzera zvakanyanya nekuti chigadziko chesimbi chinoshanda sechidzitiro chekupisa, kudzivirira maronda emhangura kubva pakusvika tembiricha apo kupokana kunokwira uye kuvimbika kunodzikisira.

Kugadzirisa Yakakwira Yazvino muSimba MCPCB: Magetsi uye Zvimiro Zvinofunga

Heavy Copper Construction

Magadzirirwo emagetsi eMCPCB anotarisa kuyerera kwemagetsi akawanda kuburikidza nehuremu hwemhangura hunorema hunoderedza kuramba kwemutyairi munzira dzemagetsi dzakakosha. Maitiro akajairwa anoshandisa mhangura ine maounces maviri kusvika matatu, nepo mashandisirwo akanyanya anogona kureva mhangura ine maounces mana kusvika matanhatu emabhazi uye matrace ane simba rakawanda.

Hukama huri pakati pemhangura ukobvu uye huwandu hwazvino hunotevera yakasimbiswa IPC-2152 nhungamiro. Iyo yekuwedzera inopisa musoro kubva kune simbi inotsigirwa inobvumira hukasha hwazvino zviyero kupfuura zvakaenzana FR4 dhizaini yaizobvumidza.

Yakagadziridzwa Trace Geometry

Trace geometry inowana kugadziriswa kwakanyatsonaka mumashandisirwo ePCB emota apo ma starting currents anogona kukwira kusvika panhamba dzepamusoro kakawanda. Mainjiniya vanoverenga upamhi hwetrace zvichienderana nezvinodiwa zve steady-state current pamwe nemamiriro e transient, vobva vaona kuburikidza ne thermal simulation kuti hapana hotspots dzinopfuura zvinodiwa ne component.

Yakapamhama inoteedzera kana nzvimbo dzakazadzwa dzemhangura dzinogovera zvazvino zvakaenzana uku ichipa nzira dzisina kuenzana dzinovandudza kukanganisa kushivirira. Iyi nzira inogonesa kushanda kwakavimbika kunyangwe pasi pemamiriro ezvikanganiso apo ikozvino inogona kutarisisa munzvimbo dzisingatarisirwe.

Mechanical Reinforcement

Mechanical kusimbisa kuburikidza nekupisa vias uye edge plating inovimbisa kutendeseka kwechimiro uko kwakakwira ikozvino kubatanidzwa kunosangana nehukuru hwemechani kushushikana. Iyo Power MCPCB kuvaka inobvumira yakananga kupisa kuburikidza nekubatanidza kune iyo simbi base, ichigadzira inoshanda yekubvisa kupisa nzvimbo chaizvo uko simba semiconductors uye magineti zvikamu zvinoburitsa kurasikirwa kwepamusoro.

Uku kubatanidzwa kwemagetsi uye ekupisa kwekugadzira nzira kunosiyanisa simba-yakatarisana neMCPCB kubva kune general-chinangwa thermal management board. Mhedzisiro ndeye bhodhi dhizaini iyo panguva imwe chete inobata yakakwirira ikozvino uye inogadzirisa iyo inopisa mhedzisiro yekuyerera kwezvino.

Kugadzirisa Kushushikana Kwekupisa: Iyo Core yeSimba MCPCB Dhizaini

Kunzwisisa Thermal Stress Formation

Kushushikana kwekushisa mumagetsi emagetsi kunobva pakuramba kuparara kwesimba kunosanganiswa nekupisa bhasikoro panguva yekushanda. Sezvinopisa zvinopisa panguva yekushanda uye kutonhorera panguva yezvisina basa, iyo coefficient yemafuta ekuwedzera kusawirirana pakati pezvishandiso zvinogadzira kushushikana kwemechini kunounganidza pamusoro pezviuru zvematenderedzwa.

Simba MCPCB kuvaka kunoderedza izvi mhedzisiro kuburikidza nekusarudza zvinhu uye yekupisa nzira optimization. Iyo simbi inotsigirwa inopa yakagadzika referensi ndege iyo inoderedza mutsauko wekuwedzera mukati mebhodhi musangano.

Thermal Conduction Path muSimba MCPCB

Nzira yekupisa inotakura kupisa inofambisa kupisa kubva panosangana ma semiconductor emagetsi kuburikidza nepakeji yavo, ichipinda mu copper circuit layer, ichipfuura nepa dielectric insulation, uye ichipinda musimbi substrate uko inopararira mativi isati yaendeswa kune external heatsink. Dielectric layer inomiririra kudzivirira kupisa kukuru munzira iyi, nezvinhu zvemazuva ano zvinosvika 1.0 kusvika 1.5 W/mK ukuwo zvichichengetedza kuparadzaniswa kwemagetsi pamusoro pe3000V.

Mainjiniya vanosarudza dielectric ukobvu zvichibva pachiyero pakati pekushanda kwekupisa uye voltage yekuzviparadzanisa nevamwe zvinodiwa, kazhinji kubva pa75 kusvika ku150 micrometer. Dielectrics dzakatetepa dzinopa zvirinani kupisa kwekuita asi inoda kutarisisa kune voltage breakdown margins.

Kusarudzwa kwezvinhu: Aluminium inopesana neCopper Base

Aluminum base MCPCB inoshanda zvakanyanya nekupisa kunotenderera kwe200 W/mK mu base plate uye inodhura zvishoma. Chinhu ichi chinopa kupararira kwakanaka kwekupisa kwesimba remagetsi riri pakati nepakati uye chinoramba chichishanda nemidziyo yakajairwa yekumisikidza.

MCPCB yesimbi inova chinhu chinodiwa kana simba rayo rikanyanya kupfuura simba rekupararira kwearuminiyamu kana kana kushandiswa kwayo kuchida kushanda kwakanyanya kwekupisa. Simba resimbi rinopa 385 W/mK thermal conductivity uye rakatsetseka zvakanyanya kuti zvikamu zvinyatsogadzirwa zvive nemazvo, kunyangwe zvichidhura zvakanyanya.

Magadzirirwo ePCB eInverter anowanzo tsanangura kuvakwa kwebase remhangura uko maIGBT modules kana MOSFETs anobvisa simba rakawanda munzvimbo dzakamanikana. Kuwedzera kwekuwedzera kwekupisa kunoreva zvakananga kuvimbika kuri nani uye kugara kwenguva refu kwezvikamu mukushandiswa uku kunoda simba.

Simba MCPCB Applications in Power Electronics Systems

Motor Driver PCB Zvinodiwa

Zvikumbiro zvePCB zvemutyairi wemota zvinoratidza mamiriro anodiwa ayo Power MCPCB inogadzirisa nemazvo. Matatu-phase motor controllers anochinja mafambiro ari pakati pe20 ne200 amperes pamafrequencies kubva kune akati wandei kilohertz kusvika kumakumi e kilohertz, zvichigadzira zvese kurasikirwa kwemaitiro mumagetsi semiconductors uye nekurasikirwa kwekuchinja panguva yetransistor shanduko.

Kutevedzana kwekutanga kunokonzeresa kushushikana sezvo inrush ikozvino inosvika kanoverengeka mazita ratings nepo control circuitry inofanirwa kuchengetedza chaiyo nguva. Simba reMCPCB kuvaka rinochengeta tembiricha yekusangana mukati memiganho yakachengeteka ichipa kugadzikana kwemakanika kunodiwa kune mota uye maindasitiri nharaunda uko vibration uye kupisa kunotyisa kunoitika nguva dzose.
