Sezvo mutakuri wekupisa uye mweya convection, iko kupisa kwekushisa kwesimba re LED kwakarongedzwa PCB inotamba chinhanho chakakosha muPS kupisa kupisa. DPC zvedongo pcb ine kwayo kwakanyanya kuita uye zvishoma nezvishoma yakaderedzwa mutengo, mune akawanda emagetsi kurongedza zvinhu zvinoratidza yakasimba kukwikwidza, ndiro ramangwana simba LED kurongedza kurongedza maitiro. Nekuvandudzwa kwesainzi uye tekinoroji uye kubuda kweye nyowani yekugadzirira tekinoroji.

Dhizaini yekupakata tekinoroji inowanzo kuvandudzwa uye ikashanduka pahwaro hwe discrete chigadzirwa kurongedza tekinoroji, asi ine hunyanzvi hwakawanda. Kazhinji, musimboti wechinhu chakaomeswa chakavharirwa mumuviri wepakeji. Basa hombe repakeji ndere kuchengetedza musimboti nekubatana kwemagetsi kwakazara. Uye kupakata kwe LED ndiko kupedzisa kuburitsa magetsi emagetsi, chengetedza iro rakajairwa pombi chubhu, kuburitsa: inoonekwa mwenje mashandiro, ese magetsi parameter, uye oparesheni parameter yedhizaini nehunyanzvi zvinodiwa, haigone kungove discrete yedhizaina chipenga che LED.

Nekuenderera mberi kwekuvandudzwa kweiyo LED chip yekuisa simba, iyo hombe kupisa kunogadzirwa neakakwira simba dissipation kunoisa kumberi kwakakwirira zvinodiwa kune akatakura ekuputira zvinhu. Mune LED kupisa kupisa chiteshi, yakarongedzwa pcb ndiyo kiyi yekubatanidza inobatanidza mukati nekunze kupisa kupisa chiteshi, ine mashandiro ekupisa kupisa chiteshi, wedunhu kubatana uye chip kutsigira kwemuviri. Zvezvigadzirwa zvine simba-zvine simba, kuputira PCBS kunoda kukwirisa kwemagetsi, kupisa kwakanyanya kupisa uye kupisa kwekuwedzera kwekukodza kunoenderana chip.

Mhinduro iripo ndeyekubatanidza chip yacho zvakananga kune radiator yemhangura, asi iyo radiator yemhangura ndiyo nzira inoitisa. Sekureva kune mashoma masosi ane chekuita, thermoelectric kuparadzaniswa hakuitwe. Pakupedzisira, iyo sosi yechiedza yakarongedzwa pabhodhi rePCB, uye imwe insulating dura ichiri kudikanwa kuti uwane thermoelectric kuparadzaniswa. Parizvino, kunyangwe kupisa kwacho kusinga simbiswe pachip, inoiswa padhuze neyakavharika pasi pechiedza. Sezvo simba rinowedzera, matambudziko ekupisa anomuka. DPC ceramic substrate inogona kugadzirisa dambudziko iri. Inogona kugadzirisa chip yakananga kune ceramic uye inogadzira yakatwasuka yekubatanidza gomba mune ceramic kuti igadzire yakazvimirira yemukati conductive chiteshi. Ceramics pachavo insulators, iyo inoparadza kupisa. Uku ndiko kupatsanurwa kwethermoelectric padanho renzvimbo yechiedza.

Mumakore achangopfuura, SMD LED inotsigira inowanzo shandisa yakanyanya-tembiricha yakagadziridzwa mainjiniya epurasitiki zvinhu, ichishandisa PPA (polyphthalamide) resin sechinhu chisina kugadzirwa, uye ichiwedzera yakagadziridzwa mafirita ekuwedzera mamwe epanyama uye emakemikari zvivakwa zvePPA mbishi zvinhu. Naizvozvo, PPA zvinhu zvinonyanya kukodzera jekiseni kuumbwa uye kushandiswa kweSMD LED mabhureki. PPA epurasitiki yekushisa inoitisa yakadzika kwazvo, kupisa kwayo kupisa kuri kunyanya kuburikidza nesimbi lead lead, kupisa kupisa simba kunogumira, inongokodzera yakaderera-simba LED kurongedza.

Kugadzirisa dambudziko rekuparadzaniswa kwethermoelectric padanho renzvimbo, zvedongo substrates dzinofanirwa kuve nehunhu hunotevera: kutanga, inofanirwa kuve neakanyanya kudziya maficha, akati wandei mirairo yehukuru hwakakwira kupfuura resin; Chechipiri, inofanira kunge iine simba rakaputira; Yetatu, iyo dunhu ine yakakwira resolution uye inogona kusunganidzwa kana kutenderedzwa ichisimuka neiyo chip pasina matambudziko. Yechina ndeye yakakwira pamusoro flatness, hakuzove nemukana kana uchipisa. Chechishanu, ceramics nesimbi zvinofanirwa kuve nekunamatira kwakakwirira; Yechitanhatu ndiyo yekumira yekubatana kuburikidza-gomba, nokudaro ichigonesa SMD encapsulation kutungamira iyo dunhu kubva kumashure kuenda kumberi. Iyo yega substrate inosangana nemamiriro aya ndeye DPC ceramic substrate.

Ceramic substrate ine yakakwira thermal conductivity inogona kuvandudza zvakanyanya kupisa kupisa kupera, ndicho chakakodzera chigadzirwa kuti kusimudzira kwesimba simba, diki saizi LED. Ceramic pcb ine nyowani yekushisa inoitisa zvinhu uye chimiro chitsva chemukati, icho chinogadzirira kukanganisa kwealuminium pcb uye inovandudza iyo yakazara kutonhora mhedzisiro yePBB. Pakati pezvinhu zveceramic parizvino zvinoshandiswa kutonhodza PCBS, BeO ine yakanyanya kupisa kupisa, asi kuwedzera kwayo kwakaringana kwakaringana kwakasiyana neiyo yesilicon, uye huturu hwayo panguva yekugadzira inogumira mashandisiro ayo. BN ine yakanaka kuita kwese, asi inoshandiswa sePCBB.

Izvo zvinhu hazvina zvazvakanakira uye zvinodhura. Parizvino iri kudzidziswa nekusimudzirwa; Silicon carbide ine simba rakakwira uye yakanyanya kudziya inoitisa, asi kupokana kwayo uye kuputira kushomeka kwakaderera, uye mubatanidzwa mushure mekugadziriswa kwesimbi hakuna kugadzikana, izvo zvinotungamira kuchinjiso mune kupisa kwemagetsi uye dielectric nguva dzose haina kukodzera kushandiswa sekudzivirira kuputira PCB zvinhu.
