3 Kupisa kwakanyanya uye kupisa kunodiwa

Iine miniaturization, kushanda kwepamusoro, uye kupisa kwakanyanya kwemagetsi emidziyo yemagetsi, izvo zvinodikanwa zvekutonga zvemagetsi zvinoramba zvichiwedzera, uye imwe yemhinduro dzakasarudzwa ndeyekugadzira thermally conductive akadhindwa edunhu mabhodhi.Mamiriro ekutanga ekupisa-kupisa uye kupisa-kubvisa maPCB ndiyo inodzivirira kupisa uye kupisa-kubvisa zvimiro zve substrate.Parizvino, kuvandudzwa kwezvinhu zvehwaro uye kuwedzerwa kwemafiritsi kwakagadzirisa kupisa-kupisa uye kupisa-kupisa zvinhu kune imwe nhanho, asi kuvandudzwa kwekupisa kwekushisa kwakanyanyisa.Kazhinji, simbi substrate (IMS) kana simbi yepakati yakadhindwa yedunhu bhodhi inoshandiswa kuburitsa kupisa kwechikamu chekudziya, icho chinoderedza huwandu uye mutengo uchienzaniswa neyechinyakare radiator uye kutonhora kwefeni.

Aluminium chinhu chinoyevedza kwazvo.Iine zviwanikwa zvakawanda, mutengo wakaderera, yakanaka thermal conductivity uye simba, uye inoenderana nenharaunda.Parizvino, akawanda simbi substrates kana simbi cores isimbi aruminiyamu.Zvakanakira zvealuminium-based circuit board zviri nyore uye zvine hupfumi, zvakavimbika zvemagetsi zvinongedzo, yakakwirira yekupisa conductivity uye simba, solder-isina uye lead-isina kuchengetedzwa kwezvakatipoteredza, nezvimwewo, uye inogona kugadzirwa uye kuiswa kubva kune zvigadzirwa zvevatengi kuenda kumotokari, zvigadzirwa zvemauto. uye aerospace.Hapana mubvunzo nezve thermal conductivity uye kupisa kupisa kwesimbi substrate.Chinokosha chiri mukushanda kweiyo insulating adhesive pakati pesimbi ndiro uye redunhu layer.

Parizvino, simba rekufambisa rekupisa kwekutonga rinotarisana ne LEDs.Inosvika 80% yesimba rekupinza remaLED rinoshandurwa kuita kupisa.Nokudaro, nyaya yehutungamiri hwekupisa kwe LED inokosheswa zvikuru, uye chinotarisa chiri pakupisa kupisa kwe LED substrate.Iko kuumbwa kweyakakwira-inodzivirira kupisa uye inoshamwaridzana kupisa kupisa dissipation insulating layer zvinhu inoisa hwaro hwekupinda mumusika wekupenya kwemwenje we LED.

4 Flexible uye yakadhindwa zvemagetsi nezvimwe zvinodiwa

4.1 Flexible board zvinodiwa

Iyo miniaturization uye kutetepa kwemidziyo yemagetsi ichashandisa nhamba huru yeinochinjika yakadhindwa yedunhu mabhodhi (FPCB) uye rigid-flex akadhindwa edunhu mabhodhi (R-FPCB).Musika wepasi rose weFPCB parizvino unofungidzirwa kunge ungangoita mabhiriyoni gumi nematatu emadhora ekuAmerica, uye mwero wekukura wepagore unotarisirwa kunge wakakwira kupfuura iwo maPCB akaomarara.

Nekuwedzera kwechishandiso, pamusoro pekuwedzera kwenhamba, pachava nezvakawanda zvitsva zvekuita zvinodiwa.Mafirimu ePolyimide anowanikwa asina ruvara uye akajeka, machena, matema, uye yero, uye ane kupisa kwakanyanya kupikisa uye kushomeka kweCTE zvimiro, izvo zvakakodzera kune dzakasiyana nguva.Inodhura-inoshanda polyester firimu substrates inowanikwawo mumusika.Matambudziko matsva ekuita anosanganisira kusimba kwepamusoro, kugadzikana kwedimensional, firimu repamusoro mhando, uye bhaisikopo photoelectric coupling uye kuramba kwezvakatipoteredza kuzadzisa zvinogara zvichichinja zvinodiwa zvevashandisi vekupedzisira.

FPCB uye yakaoma HDI mabhodhi anofanirwa kusangana nezvinodiwa zvekumhanya-mhanya uye yakakwirira-frequency chiratidzo chekufambisa.Iyo dielectric inogara uye dielectric kurasikirwa kweanochinjika substrates inofanirawo kutariswa.Polytetrafluoroethylene uye advanced polyimide substrates inogona kushandiswa kugadzira kuchinjika.Circuit.Kuwedzera inorganic poda uye kabhoni fiber filler kune polyimide resin inogona kuburitsa matatu-layer chimiro cheinochinjika thermally conductive substrate.Iwo inorganic fillers anoshandiswa aluminium nitride (AlN), aluminium oxide (Al2O3) uye hexagonal boron nitride (HBN).Iyo substrate ine 1.51W/mK thermal conductivity uye inokwanisa kushingirira 2.5kV kushingirira voltage uye 180 dhigirii kubhenda bvunzo.

Misika yemashandisirwo eFPCB, senge nharembozha, midziyo inopfekwa, michina yekurapa, marobhoti, nezvimwe, inoisa pamberi pezvitsva zvinodiwa pamaitiro eFPCB, uye yakagadzira zvigadzirwa zvitsva zveFPCB.Zvakadai se-ultra-thin flexible multilayer board, mana-layer FPCB yakaderedzwa kubva kune yakajairwa 0.4mm kusvika kune 0.2mm;high-speed transmission flexible board, kushandisa yakaderera-Dk uye yakaderera-Df polyimide substrate, inosvika 5Gbps yekufambisa kukurumidza zvinodiwa;hombe Simba rinoshanduka bhodhi rinoshandisa conductor pamusoro pe 100μm kuti isangane nezvinodiwa zvemasimba makuru uye epamusoro-zvino matunhu;iyo yakanyanya kupisa kupisa simbi-based flexible board ndeye R-FPCB inoshandisa simbi plate substrate zvishoma;iyo tactile flexible board is pressure-sensed The membrane uye electrode inoputirwa pakati pemafirimu maviri e polyimide kuti iite flexible tactile sensor;bhodhi rinotambanuka rinochinjika kana bhodhi rakaomesesa, iyo inochinjika substrate ndeye elastomer, uye chimiro chesimbi waya pateni inovandudzwa kuti itambanuke.Ehe, aya akakosha maFPCB anoda asina kujairika substrates.
