Panopa, organic makamaka zipangizo epoxy utomoni pa zotchipa ndi okhwima luso mbali ambiri kupanga PCB, ndi ochiritsira organic kusindikizidwa dera bolodi mbali ziwiri kutentha madyaidya ndikuledzera ndi matenthedwe kuwonjezeka koyefishienti zofanana kugonana, simungathe kukumana ndi zofunikira za kusakanikirana michenga yopangira zida zamagetsi dera timapitiriza zinthu unceasingly.Ceramic ali wabwino mkulu pafupipafupi ntchito ndi ntchito magetsi, ndipo ali mkulu matenthedwe madutsidwe, bata mankhwala ndi matenthedwe mtendere wa magawo organic monga mulibe ntchito zabwino, ndi mbadwo watsopano wa Integrated dera lalikulu lonse ndi mphamvu zamagetsi gawo la abwino ma CD material.Therefore, zaposachedwapa, Ceramic Board PCBwalandira chidwi zedi ndi chitukuko mofulumira.
Ceramic dera bolodi ceramic ofotokoza metallized gawo lapansi ndi katundu wabwino matenthedwe ndi magetsi, ndi mtundu mphamvu LED encapsulation, zinthu kwambiri, wofiirira kuwala, ultraviolet (MCM) ndipo makamaka woyenerera ambiri Chip phukusi magawo monga mwachindunji kulumikiza (chisononkho) Chip encapsulation kapangidwe; pa nthawi yomweyo, zikhoza kugwiritsidwa ntchito monga kutentha madyaidya ndikuledzera dera gulu la ena zigawo mkulu-mphamvu mphamvu michenga yopangira zida zamagetsi, lalikulu magetsi panopa, kulandirana, makampani telefoni mlongoti, fyuluta, dzuwa inverter, etc.
Pakali pano, ndi chitukuko cha dzuwa mkulu, mkulu osalimba, ndi mphamvu mkulu makampani LED kunyumba ndi kunja, Tingaone 2017 ndi 2018, wonse zoweta anatsogolera patsogolo mofulumira, ikukula mu mphamvu, kukula kwa ntchito kuposa kutentha zinthu madyaidya ndikuledzera wakhala mwamsanga kuthetsa vuto la LED kutentha dissipation.In zambiri, LED mwachangu wowala ndi utumiki moyo m'tali ndi kuwonjezeka kutentha yakumapeto, pamene mphambano kutentha 125 ℃ pamwamba, inatsogolera mungathe kuoneka kuti ngakhale failure.In kusunga kutentha LED pa kutentha otsika, mkulu matenthedwe madutsidwe, otsika kutentha kukana ndi wololera ma CD ndondomeko ayenera anavomerezedwa kuchepetsa wonse matenthedwe kulimbikira kutsogoleredwa.
Epoxy mkuwa atavala magawo ndi magawo ambiri ankagwiritsa ntchito packaging.It miyambo pakompyuta ali ntchito zitatu: thandizo, conduction ndi mbali insulation.Its chachikulu ndi: mtengo wotsika, mkulu chinyezi kukana, otsika kachulukidwe, zosavuta ndondomeko, zosavuta kuzindikira micrographics dera , oyenera misa production.But chifukwa cha FR - 4 m'munsi zakuthupi epoxy utomoni, organic wa otsika matenthedwe madutsidwe, mkulu kutentha kukana ndi osauka, kotero FR - 4 sangathe atengere kachulukidwe mkulu mphamvu LED amafuna mkulu ma CD, zambiri yekha ntchito mphamvu yaing'ono LED ma CD.
Ceramic zipangizo gawo lapansi makamaka aluminiyamu, Aluminiyamu nitride, safiro, High Borosilicate Glass, etc. Poyerekeza ndi zipangizo zina gawo lapansi, ceramic gawo lapansi ali ndi makhalidwe awa katundu makina, katundu magetsi ndi katundu matenthedwe:
(1) katundu Mawotchi: Mawotchi mphamvu kungakhale ntchito ngati zigawo akuthandiza; processing Good, mkulu ooneka enieni olondola; Mosyasyalika padziko, palibe microcracks, kupinda, etc.
(2) matenthedwe katundu: The madutsidwe matenthedwe waukulu, ikukhudzana kuwonjezeka koyefishienti ndi chikufanana ndi Si ndipo GaAs ndi zipangizo zina Chip, ndi kutentha kukana ndi wabwino.
(3) Magetsi katundu: mosalekeza dielectric ndi otsika, imfa dielectric ndi zazing'ono, kutchinjiriza kukana ndi kulephera kutchinjiriza ndi mkulu, ntchito ndi khola pansi kutentha ndi chinyezi mkulu, ndiponso kudalirika mkulu.
(4) katundu Other: Good mankhwala bata, palibe mayamwidwe chinyezi; Mafuta kugonjetsedwa ndi mankhwala kusamva; Non-poizoni, kuipitsa-free, Alpha ray umuna ndizochepa; Kapangidwe galasi ndi okhazikika, ndipo si kophweka kusintha kutentha range.Abundant yaiwisi chuma.
Kwa nthawi yaitali, Al2O3 ndicho gawo lapansi chuma cha mphamvu mkulu packaging.But ndi madutsidwe matenthedwe wa Al2O3 ndi otsika, ndi ikukhudzana kuwonjezeka koyefishienti sakugwirizana Chip material.Therefore, mwa mawu a ntchito, ndalama ndi kuteteza chilengedwe, izi gawo lapansi chuma sangakhale nkhani yabwino kwambiri pa chitukuko cha zipangizo mkulu-mphamvu LED m'tsogolo. Zotayidwa nitride ziwiya zadothi ndi mkulu kutentha madutsidwe, mphamvu yapamwamba, mlingo zonyamula, kachulukidwe yaing'ono, otsika dielectric zonse, si poizoni, komanso katundu kwambiri monga kufutukuka koyefishienti matenthedwe wa ofananira ndi Si, pang'onopang'ono m'malo miyambo mkulu-mphamvu LED gawo lapansi chuma, kukhala chimodzi mwa zinthu tsogolo zipangizo ceramic gawo lapansi, kupereka kuposa 180W ~ 220w / Marko, KingSong amapereka ceramic matabwa kusindikizidwa dera lanu PCB.
