Okwangoku, i-organic ngakumbi izinto nentlaka epoxy ngamaxabiso aphantsi kunye nobugcisa oqolileyo inxalenye kusekho kakhulu kwimveliso PCB, kwaye eqhelekileyo organic eshicilelweyo ibhodi zeesekethe ukususela iinkalo ezimbini melelo wokuzibhubhisa ubushushu thermal nokwandiswa lomlingani sex ezifana eziphathekayo, akakwazi ukuhlangabezana iimfuno ukuhlanganiswa semiconductor zeesekethe kuphucula izinto unceasingly.Ceramic unokuhle yokusebenza rhoqo kunye yokusebenza yombane, yaye conductivity thermal phezulu, uzinzo iikhemikhali kunye nozinzo thermal of substrates organic ezifana musa ukuba ukusebenza okulungileyo, isizukulwana esitsha omkhulu yesekethe ezihlangeneyo namandla imodyuli elektroniki efanelekileyo zokubopha material.Therefore, kwiminyaka yakutshanje, Board PCB ceramicifumene ingqalelo olunzulu ekhawulezayo yobhekiso phambili.
ibhodi yesekethe bokusebenzisa metallized yodongwe-based zeendawana kunye iipropati elungileyo thermal kwaye zombane, uhlobo lwamandla encapsulation LED, izinto zobuhlalu, ukukhanya ezimfusa, yiultraviolet (MCM) kwaye sifanelekile ngokukhethekileyo abaninzi iiphakheji chip substrates ezifana ubuhlobo ngqo (ba-) chip encapsulation isakhiwo, Kwangaxeshanye, lingakwazi kusetyenziswa kwibhodi wesiphaluka bubushushu ukusasaza ezinye iimodyuli amandla eliphezulu-power semiconductor, switsha elikhulu ngoku, irileyi, Uphondo kushishino zonxibelelwano, filter, inverter elanga, njl
Okwangoku, kunye nophuhliso kahle eliphezulu, ezixineneyo, namandla phezulu kushishino LED apha ekhaya nakumazwe aphesheya, oko kubonakala ukususela 2017 ukuya ngo-2018, abantu ngokubanzi zasekhaya LED inkqubela ekhawulezileyo, olukhulayo ngamandla, uphuhliso yokusebenza engcono izinto ukusasaza ubushushu kuye kungxamisekile ukusombulula ingxaki yobushushu LED dissipation.In jikelele, i-LED ukusebenza ezikhanyayo kunye nenkonzo ubomi enqaba kunye nokwanda lobushushu kuhlangana khona, xa ubushushu kuhlangana ka 125 ℃ ngasentla, le LED ungakwazi kuvela ukuze nokuba failure.In ukugcina lobushushu LED kubushushu obuphantsi, conductivity thermal phezulu, ukumelana abile kunye nenkqubo nokupakishwa ezifanelekileyo kufuneka sithatyathwe ukunciphisa uxhathiso iyonke wobushushu ka-LED.
Epoxy yobhedu substrates evathe zezona lwimi zisetyenziswa substrates e packaging.It bemveli yekhompyutha misebenzi mithathu: inkxaso, Uhanjiso kunye neempawu insulation.Its eziphambili zezi: ngendleko ephantsi, ukumelana phezulu ukufuma, ingxinano phantsi, kulula inkqubo, kulula ukuqonda micrographics beesekethe , ifanele mass production.But ngenxa responce - 4 impahla isiseko na epoxy resin, izinto kweziphilayo conductivity thermal ephantsi, ukumelana lobushushu eliphezulu ulihlwempu, ngoko FR - 4 ayikwazi ukuzivumelanisa ezixineneyo, amandla LED iimfuno phezulu ukuphakheja, zisetyenziswa kuphela lamandla amancinane ukuphakheja LED.
Izinto zeendawana bokusebenzisa ikakhulu Alumina, aluminium ephuculweyo, Sapphire, Borosilicate High Glass, njl Xa kuthelekiswa nezinye izinto zeendawana, zeendawana yodongwe neneempawu zilandelayo kwiipropati mechanical, iimpawu zombane kunye neempawu thermal:
(1) Iipropati Mechanical: amandla Mechanical kungaba kusetyenziswa nokuxhasa amacandelo; processing Good, ukuchaneka eliphezulu mbini; umphezulu Smooth, akukho microcracks, ayeguqa, njl
(2) iipropati thermal: i conductivity thermal inkulu, ukwanda lomlingani thermal into ifaniswe i Si kunye Gaas kunye nezinye izinto chip kwaye ukumelana nobushushu ulungile.
(3) Iipropati Electrical: abehla Heating iphantsi, ukulahlekelwa Heating incinane, le elana kwaye ukusilela yokugquma ziphezulu, ukusebenza uzinzile phantsi lobushushu eliphezulu nokufuma ephakamileyo, kwaye nokuthembeka uphezulu.
(4) Ezinye iimpawu: uzinzo Good imichiza, akukho ukufakwa ubumanzi; Oli ukumelana nemichiza enganyangekiyo; Non-ezingenabungozi, ungcoliseko-free, alpha ray ukukhutshwa yinto encinane; Isakhiwo crystal uzinzile, kwaye akukho lula ukutshintsha kobushushu izixhobo eziphathekayo range.Abundant ekrwada.
Kangangexesha elide, Al2O3 yeyona nto iphambili zeendawana kwamandla aphezulu packaging.But na conductivity wobushushu ka Al2O3 lisezantsi, kwaye nokwandiswa lomlingani thermal ayihambelani material.Therefore chip, ngokwemigaqo yokusebenza, iindleko kunye ukhuselo lokusingqongileyo, lo izinto zeendawana ayikwazi kuba izinto kakhulu efanelekileyo ukwenzela uphuhliso ophezulu-amandla izixhobo iLED kwixesha elizayo. Aluminium ephuculweyo ukubumba kunye conductivity high ubushushu, amandla aphezulu, izinga ukumelana eliphezulu, ingxinano encinane, ukusoloko Heating ephantsi, non-ityhefu, kwakunye iimpawu ezigqwesileyo ezifana thermal nokwandiswa ukungavumelani kwe naso kunye Si, uya ngokuthe ngcembe indawo emveli high-amandla LED izinto zeendawana, abe ngomnye izinto zeendawana yodongwe elizayo ethembisayo, ngokubonelela mkhulu 180W ~ 220w / MK, KingSong inika iibhodi wesekethe yodongwe eshicilelweyo iimfuno zakho PCB.
