I reira, te rauemi organic rawa hoki ngā rauemi kapia epoxy i utu iti me te toi pakeke mo te wahi tonu te nuinga i roto i te PCB production, me tikanga organic te poari taiawhio tāngia i rua ngā āhuatanga o te tohanga wera me te ngāwhā roha whakarea ōrite sex, e kore e taea te whakatau i te whakaritenga o te Semiconductor haaati kōmitimiti whakarei ake rauemi unceasingly.Ceramic he pai ana te whakahaere auau nui, me te mahi hiko, me he kawe ia ngāwhā tiketike, pūmautanga matū me te pūmautanga waiariki o substrates organic pērā i kore e whai pai ana te whakahaere, ko te whakatupuranga hou o te tauine nui taiawhio integrated me te mana kōwae hiko o material.Therefore tākai pai, i roto i nga tau tata nei, Poari PCB ukukua riro ngā aro me te whanaketanga tere.
Uku poari ara iahiko metallized hāngai uku-tïpako ki ngā āhuatanga waiariki, me te hiko pai, he he momo mana encapsulation arahina, rauemi pai, marama papura, katinga (MCM) me he tino hāngai ki maha pōkai maramara substrates pērā i te hononga hāngai (wä) maramara encapsulation hanganga; I te wa ano, hoki e taea te whakamahi i te reira rite te tohanga wera poari taiawhio o te tahi atu kōwae mana-nui mana Semiconductor, pana nui o nāianei, tānga, ahumahi aratuku pūihi, tātari, inverter solar, me ētahi atu
I reira, ki te whanaketanga o te pai nui, kiato tiketike, me te mana nui i roto i te ahumahi arahina i te kāinga, me te ki waho, e taea te kite i te reira i 2017 ki te 2018, te kāinga arahina te ahunga whakamua tere whānui, kei te tipu haere i roto i te mana, te whanaketanga o hei mahi pai o te rauemi tohanga wera kua akiaki ki te whakaoti i te raruraru o te dissipation.In whānui wera arahina, pato'i te arahina pai te tiahoaho me te mahi ora ki te hua o te pāmahana huinga, ka te pāmahana komititanga o 125 ℃ i runga, e taea te arahina puta kia noa failure.In ki te pupuri i te pāmahana arahina i te pāmahana iti, kawe waiariki tiketike, resistance wera iti me te tukanga tākai whaitake me whāngai kia ki te whakaiti i te ātete waiariki whānui o LED.
Epoxy parahi substrates kakahuria ko nga substrates tino whakamahia whānuitia i roto i te packaging.It hiko tuku iho kua toru mahi: tautoko, āriponga me insulation.Its āhuatanga matua e: utu iti, ātete makuku tiketike, kiato iti, ngāwari ki te tukanga, ngāwari ki te ite micrographics iahiko , e tika ana mō te papatipu production.But rite ki te hua o te FR - 4 rauemi turanga ko epoxy kapia, rauemi organic o iti kawe ia waiariki, he rawakore tiketike pāmahana ātete, na FR - e kore e taea e 4 urutau ki kiato tiketike, tiketike kaha arahina ngā whakaritenga tākai, te tikanga anake e whakamahia ana i roto i te iti te kaha tākai arahina.
Ko te nuinga rauemi tïpako Ceramic Alumina, Konumohe nitride, hapaira, High Borosilicate Glass, etc. Ina whakaritea ki rauemi tïpako atu, kua nga āhuatanga e whai ake nei i roto i ngā āhuatanga hangarau, ngā āhuatanga hiko me ngā āhuatanga waiariki tïpako uku:
(1) āhuatanga Mechanical: Mechanical kaha e taea e whakamahia rite tautoko wae; tukatuka pai, tika ahu tiketike; mata Smooth, kahore microcracks, piko, me ētahi atu
(2) āhuatanga Thermal: he nui te kawe ia waiariki, ki āu i te whakarea roha ngāwhā te ki te Si me Kaaha me ngā rauemi maramara atu, a he pai te ātete wera.
(3) āhuatanga Electrical: he iti te tamau uruhanga, he iti te mate uruhanga, te resistance mātao me te kore mātao e tiketike, he kainga i raro i tiketike pāmahana me te haumākū nui te mahi, a ko te tiketike o te tika.
(4) Ētahi atu āhuatanga: pūmautanga matū pai, kahore absorption makuku: Oil ātete, me te matū ātete: Non-paitini, he pollution-free, Arepa hihi tukunga iti: he pūmau te hanganga karaihe, a kahore he mea ohie ki te huri i roto i te pāmahana range.Abundant rauemi rauemi raw.
Hoki te wa roa, Al2O3 ko te rauemi tïpako matua o te mana tiketike packaging.But ko te kawe ia waiariki o Al2O3 iti, a kahore e te whakarea roha ngāwhā ōrite te material.Therefore kongakonga, i roto i ngā o te mahi, utu me te tiaki i te taiao, tenei e kore e taea e rauemi tïpako hei te rauemi pai tino mo te whanaketanga o te kaha-tiketike pūrere arahina i roto i te heke mai. Konumohe nitride okouku ki te kawe ia nui wera, kaha nui, auau ātete tiketike, kiato iti, iti tamau uruhanga, kore-paitini, me te āhuatanga pai pērā i whakarea roha waiariki te ōrite ki te Si o, āta ka whakakapi mana-nui tuku iho rauemi tïpako arahina, hei tetahi o nga rauemi tïpako uku heke mai tino whaihua, whakarato nui atu 180W ~ 220w / MK, KingSong tuku uku papa iahiko tāngia mo koutou hiahia PCB.
