Panguva ino, makemikari acho kunyanya epoxy nebwe zvinhu nemitengo yakaderera uye vakura uri vakawanda ichiri pcb kugadzirwa, uye kwakajairika Organic rakadhindwa redunhu pepuranga kubva zviviri nokupisa nounzenza uye chafariz kuwedzera coefficient chienderane bonde, havagoni kusangana zvinodiwa semiconductor redunhu kusangana runogonesa unceasingly.Ceramic zvinhu ine zvakanaka mukuru Frequency kuita uye magetsi kuita, uye ane yakakwirira chafariz conductivity, zvemakemikari kutsiga uye chafariz kugadzikana Organic substrates akadai vasina mabasa akanaka, ari chizvarwa chitsva pamwero Integrated redunhu uye simba zvemagetsi module pamusoro akanaka kavha material.Therefore, mumakore achangopfuura, Ceramic pcb Boardakagashira akakura kutarisirwa uye nokukurumidza kukura.
Ceramic redunhu bhodhi zvedongo anotsanangura metallized substrate nezvakanaka chafariz uye magetsi zvivako, ane simba mhando akatungamirira encapsulation, chakanakisisa zvinhu, yepepuru chiedza, ultraviolet (MCM) uye kunonyanya unoenderana zhinji Chip package substrates zvakadai zvakananga chokuedza (Cob) Chip encapsulation mamiriro; panguva iyoyowo, zvinogonawo kushandiswa kupisa nounzenza redunhu Board vamwe mukuru-simba simba semiconductor modules, hombe chinja ano, ataure, telecommunication indasitiri kanyanga, Sefa, zuva inverter, etc.
Panguva ino, pamwe pave mukuru kunyatsoshanda, matunhu arambe achirema, uye yakakwirira nesimba kwakaita indasitiri kumba uye kunze, anogona kuonekwa kubvira 2017 kusvika 2018, zvinonakisa mudzimba akatungamirira kufambira mberi, riri kukura simba, kukura mukuru chokupika kupisa nounzenza zvinhu zvava zvokukurumidzira kugadzirisa dambudziko racho kwakaita kupisa dissipation.In mukuru, ari akatungamirira luminous kunyatsoshanda uye basa upenyu kupera pamwe zvibereko zveminda mhesano tembiricha, apo panosangana tembiricha kuti 125 ℃ kumusoro, akatungamirira anogona kuonekwa kunyange failure.In kuti kuchengeta akatungamirira tembiricha ari tembiricha yakaderera, yakakwirira chafariz conductivity, pasi kupisa kuzvidzivirira uye anonzwisisa kavha muitiro anofanira wokurera kuderedza zvinonakisa chafariz nemishonga kuti akatungamirira.
Epoxy mhangura akapfeka substrates ndivo inonyanya kushandiswa substrates mune zvetsika yemagetsi packaging.It ane Mabasa matatu: rutsigiro, conduction uye insulation.Its chikuru zvinhu vari: yakaderera cost, mukuru mwando nemishonga, pasi arambe achirema, nyore muitiro, nyore kuziva micrographics vematunhu , yakakodzera vakawanda production.But somugumisiro FR - 4 chawo zvinhu ndiyo epoxy nebwe, makemikari zvinhu yakaderera chafariz conductivity, mukuru tembiricha kuramba ari murombo, saka FR - 4 havagoni kuchinja mukuru arambe achirema, mukuru simba akatungamirira kavha zvinodiwa, kazhinji chete kushandiswa simba duku akatungamirira kavha.
Ceramic substrate zvinhu zviri kunyanya Alumina, Aluminum nitride, nesafiri, High Borosilicate Glass, etc. zvichienzaniswa nevamwe substrate zvinhu, zvedongo substrate ane zvinotevera unhu zvemaziso ehupfumi, nemagetsi zvivako uye chafariz zvivako:
(1) Mechanical ehupfumi: simba Mechanical kunogona kuva anoshandiswa kutsigira zvinoriumba izvozvo; kubudiswa Good, yakakwirira ndeiya yakaita zvakarurama; Smooth pamusoro, hapana microcracks, vachikotama, nezvimwewo
(2) Thermal ehupfumi: The chafariz conductivity iri huru, chafariz kuwedzera coefficient iri vachiwirirana pamwe Si uye GaAs nezvimwe Chip zvokuvakisa, uye nokupisa kuramba akanaka.
(3) Electrical ehupfumi: The dielectric achitsungirira ari pasi, iyo dielectric kurasikirwa chidiki, kuputira kurwisa uye kuputira kukundikana marefu, chokupika akatsiga pasi kumusoro tembiricha uye yakakwirira mwando, uye rakavimbika zvakakwirira.
(4) Other ehupfumi: Good namakemikari Kugadzikana, hapana hunyoro Absorção de Água; Oil nemishonga uye mushonga nemishonga; Non-chepfu, isina, Alpha ranzi achine chinhu chiduku; The sekristaro Murongerwo akatsiga, uye hazvisi nyore kuchinja mune tembiricha range.Abundant mbishi pfuma.
Kwenguva refu, Al2O3 Nde substrate zvinhu mukuru simba packaging.But ari chafariz conductivity pamusoro Al2O3 riri pasi, uye chafariz kuwedzera coefficient hakurevi kuenzaniswa Chip material.Therefore, tichitarisa maitiro, mutengo uye kudzivirira zvakatikomberedza, ichi substrate zvinhu haagoni kuva zvinhu zvikuru rakanakira kukura mukuru-simba akatungamirira mano mune ramangwana. Aluminum nitride Ceramics dzakakwirira kupisa conductivity, mukuru simba, mukuru nemishonga zvazvingava, arambe achirema duku, pasi dielectric kugara, dzisiri chepfu, uyewo nzvimbo yakanaka zvakadai chafariz kuwedzera coefficient of enzanirana pamwe Si, zvishoma nezvishoma kutsiva zvetsika mukuru-simba akatungamirira substrate zvokunyama, akava mumwe vaizotibata zvikuru ramangwana zvedongo substrate zvinhu, ichipa mukuru 180W ~ 220w / Mk, KingSong anopa zvedongo akadhindwa redunhu mapuranga ako pcb zvinodiwa.
