Intshayelelo kwi-Conper Reper Ceraphy Ceramic Free (DBC).

Inkqubo ye-DBC ye-DBC yeyokongeza izinto ze-OXYGENT phakathi kobhedu kunye ne-ceramics, fumana ulwelo lwe-CU-o kwiqondo lokushisa kwi-1065 ~ 483 ° 2 ~ yeplate ye-CU kunye ne-ceramic ye-cellic sucturgy, kwaye ekugqibeleni ngetekhnoloji yeli lichografi ukufezekisa amalungiselelo ephethini, enze isekethe.

I-Cemiramic PCB ihlulwe yangamacala ama-3, kwaye izinto zokuthambisa ziphakathi yi-al22o3 okanye i-aln. Ukuqhubela kwe-Al2o3 yi-24 w / (m · k / (kunye nokuphumelela kwe-Aln yi-170 W / (M · k / (m · k / (m · k / (m · k. Ukungasebenzi kokwandiswa kwe-ceramic ye-DBC kuyafana ne-al23 / i-aln, esondelelene kakhulu kuxinzelelo lwe-spital of theital olwenziwe phakathi kwe-chip kunye ne-ceramic efihliweyo subsare.

Kuba i-foil yobhedu inesifo sokusebenza kombane kunye nokuqhutywa kwe-irhula, kwaye i-Aluminiya inokulawula ngokufanelekileyo ukwanda kwe-CU-AL2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2 Al2-Cu, i-DBC inezinto ezilungileyo Ukuqhutywa kwe-shirmal, ukufakelwa okuqinileyo kunye nokuthembeka okuphezulu, kwaye kusetyenziswe ngokubanzi kwi-Igbt, i-LD kunye ne-CPV. Eyona nto ibaluleke kakhulu kwi-foil yoshicilelo lodaka (100 ~ 600μm), inezibonelelo ezibonakalayo kwicandelo le-Igbt kunye ne-Ld ukupakisha.

Kwinkqubo yokulungiselela ye-DBC, ubushushu obushushu kunye kunye nesihloko seoksijini kufuneka silawulwe ngokungqongqo, kwaye ixesha le-oxidation lelona paramenti mibini ibaluleke kakhulu. Emva kokuba i-foil yobhedu iphambi kwe-oxdid i-oxidlid, i-Wit Poist inokuthi isebenze ngokwaneleyo i-Cusoy iSigaba se-cuxoy sel26 ceramic kunye ne-coper moil, amandla aphezulu abophelelayo; Ukuba i-foil yobhedu ayingasebenzi kwangaphambili, i-cuxoy gotous ihlwempu, kwaye inani elikhulu lemingxunya kunye neziphene ziya kuhlala kwi-bondiles yobumbeko, ukunciphisa amandla aphezulu. Ukulungiswa kwe-DBC isebenzisa iifilimu ze-ALY Ceramics, ikwayimfuneko ukuphakamisa amayeza e-ceramic, ifom yeFomu ye-AL22O3, emva koko iphendule i-foild forting yokuphendula.
