I kēia manawa,ʻo ke aloha nā oi loa aku hoi no ka pīlali kēpau noi ma haʻahaʻa kala a me oʻo nō no ka hapanui loa nō i loko o PCB? Iecaianoaaiiuo, a me kaʻike mau ke aloha pai ia huakai kaapuni a papa mai elua, ao ke ano o ka wela dissipation a me thermal? Anoe? Kaʻi lau waiwai'ālike ke keka, hiki ole hālāwai me ka olelo o ka mea uholo uila huakai kaapuni a hoʻohui 'hoʻokāʻoi aʻe ana i unceasingly.Ceramic mea, he maikai kiʻekiʻe alapine (frequency) hana ana a me ka uila hana, a ua kiʻekiʻe thermal conductivity, Nine Inch kumupaʻa a me thermal kumupaʻa o ke aloha substrates e like me e mai i ka pono hana, o ka hou hanauna o ka nui me ka unahiʻole noniakahi kaapuni a me ka mana lolouila Module o maikaʻi'ōpala material.Therefore, i loko o nā makahiki, Pālolo PCB Boardi loaa nui noonoo a me ka kokololio? acaeoey.
Pālolo kaapuni papa pālolo-ma muli metallized kūpapakū me ka maikai thermal a me ka pou waiwai, o ka manaʻano alakaʻi encapsulation, maikaʻi mea, he poni malamalama, ultraviolet (MCM) a me ka mea nui hoʻomākaukau i na mea he nui? Inoaia pūʻolo helu substrates e like me pololei ka ponaʻana (COB)? Inoaia encapsulation 'ole; ma ka ia manawa, ka mea hiki ke hoʻohana pū me ka wela dissipation kaapuni papa o nā kiʻekiʻe-mana mana mea uholo uila modules, nui he kuapo, mika, kelekaʻaʻike hana kukuna, Kānana, poe mea hoʻololi, etc.
I kēia manawa, a me ka hooulu ana o ka kiʻekiʻe ka hoʻokōʻana, kiʻekiʻe nuʻa, a me ka mana kiʻekiʻe i loko o ke alakai hana ma ka home, a ma kahi e aku, ka mea hiki ke ike mai 2017 a hiki i 2018, i ka pono wahi lulu alakai i ka kokololio holomua, ua ulu i loko o ka mana, i ka ulu ana o ka oi hana o ka wela dissipation mea ua lilo ka manaʻo e hoʻoponopono i ka pilikia o ka mea alakaʻi wela dissipation.In mau, ke alakai luminous ka hoʻokōʻana a me ka hana ola hoole me ka mea ulu o ka huina ana wela, i ka wa a ka huina mahana o ka 125 ℃ luna, i ka LED e hiki hou a hiki failure.In mea e malama i ka alakaiia mai mahana ma ka haʻahaʻa wela, pono e hoohana kiʻekiʻe thermal conductivity, haahaa wela ia'ku, a kupono'ōpala kaʻina e emi ai ka pono thermal ia'ku o LED.
Pīlali keleaweʻaʻahuʻia substrates i ka loa hoʻomano hoʻohana substrates i kahiko lolouila packaging.It i ekolu oihana: kākoʻo, conduction a me insulation.Its ka papa kuhikuhiE hiʻona i: haʻahaʻa waiwai e lilo aku, kiʻekiʻe ona mau ia'ku, haʻahaʻa nuʻa, oluolu ke kaʻina, oluolu e hoʻomaopopo micrographics kaapuni , pono no ka nuipa a production.But like me ka hopena o FR - 4 kumu lako e ka pīlali kēpau, ke aloha i nā puke o ka haʻahaʻa thermal conductivity, kiʻekiʻe wela ia'ku mea ilihune, no laila, FR - 4 hiki ole ke hakuloli i ka kiʻekiʻe nuʻa, kiʻekiʻe mana alakai'ōpala koi, nui wale i hoʻohana i ka poe liilii, mana alakaʻi'ōpala.
Pālolo kūpapakū kumuhana iʻano nui Alumina, Aluminum nitride, aiai, High Borosilicate aniani, etc. Ke hoʻohālikelike me nā kūpapakū kumuhana, pālolo kūpapakū i ka kēia mau 'ano i loko o ÿano waiwai, pou waiwai a me thermal waiwai:
(1) Mechanical waiwai: Mechanical ikaika hiki e hoʻohana 'ia e like me ke kākoʻo eiiiiiaiou; Good aaioee, kiʻekiʻe dimensional pololei; Kaulu,ʻaʻohe microcracks, anuenue, etc.
(2) Thermal waiwai: ka thermal conductivity mea nui, i ka thermal? anoe? kaʻi lau waiwai ua like ia me ka Si a me GaAs a me nā pono hana? inoaia, a me ka wela ia'ku mea maikai.
(3) pou waiwai: ka dielectric a eia i mea haʻahaʻa, ka dielectric poho mea liʻiliʻi, ke'īpale ia'ku, a me ka'īpale 'ole e kiʻekiʻe, i ka hana ana i ka pilina paʻa ma lalo o kiʻekiʻe ka mahana, a kiʻekiʻe humidity, a me ka pono mea kiʻekiʻe.
(4) Other waiwai: Good Nine Inch kumupaʻa,ʻaʻohe ona mau omo; Oil hoʻopale a me ka Nine Inch hoʻopale; ole-ʻawahia, haumia ea-noa, alpha Ray ea puka mea uuku; ke aniani 'ole i ka pilina paʻa, a me ia mea i oluolu i ka hoʻololi' ana i loko o ke ana wela range.Abundant maka mea kumu waiwai.
No ka lōʻihi manawa, Al2O3 o ka papa kuhikuhiE kūpapakū nā ana kiʻekiʻe mana packaging.But ka thermal conductivity o Al2O3 mea haʻahaʻa, a me ka thermal? Anoe? Kaʻi lau waiwai 'aʻole i like loa me ka? Inoaia material.Therefore, ma ka olelo o ka hana ana, a me ka lilo? Aneie maluhia, keia kūpapakū mea hiki ole ia i ka loa maikaʻi mea no ka hooulu ana i kiʻekiʻe-mana alakai maalea i loko o ka wā e hiki mai. Aluminum nitride pālolo me kiʻekiʻe wela conductivity, kiʻekiʻe ikaika, kiʻekiʻe ia'ku ana, uuku nuʻa, haʻahaʻa dielectric ikaika, ole-ʻawahia, e like me ka maikai o ka waiwai e like me thermal? Anoe kaʻi lau waiwai o ka'ālike me ka Si, e ke kiʻekiʻe o puku kahiko kiʻekiʻe-mana alakaʻi kūpapakū mea, ua lilo kekahi o ka loa i olelo mua iaʻi wā e hiki mai pālolo kūpapakū kumuhana, ka hoʻolako 'oi aku ma mua o 180W ~ 220w /'āina, KingSong e kaumaha ana pālolo i paiia kaapuni papa no kou PCB pono ai.
