Hoʻokumu ʻia nā PCB Ceramic i nā seramika e like me kā lākou kumu kumu, a koi lākou i nā mahana hana kiʻekiʻe ma mua o nā PCB ʻē aʻe. Ma ke ʻano he kumu kumu PCB, ʻoi aku ka maikaʻi o nā ceramics i hoʻohana ʻia no nā PCB i ka FR4 a me ka metala. ʻO nā mea FR4 he uila uila, akā maikaʻi ʻole ka conductivity thermal; ʻO ka aluminika a me ke keleawe ka maikaʻi o ka thermal conductivity, akā he mau conductors lākou. Loaʻa i nā PCB Ceramic ka conductivity wela maikaʻi a ʻaʻole koi i kahi papa hoʻokaʻawale uila no ka mea he insulators maikaʻi nā ceramics.

Ke kau ʻia nā PCB seramika me nā ʻāpana LED, IC, a me nā mea ʻē aʻe, lilo lākou i PCBA ceramic. Hiki ke hōʻuluʻulu ʻia nā LED ma nā PCB seramika ma o ka hoʻopaʻa ʻana i ka uea a i ʻole ke ʻano flip-chip. ʻO ka Ceramic PCBA ka mea maʻamau i nā ʻāpana nui i ka mana kiʻekiʻe a me nā noi kiʻekiʻe, e like me nā mana kaʻa kaʻa, nā ʻōnaehana optical variable, nā mea hoʻololi hoʻololi, nā pihi mana o ka lā, nā kukui LED kiʻekiʻe ...

No ke aha i kaulana ai ka PCB ceramic?

Hoʻonui Thermal Kiʻekiʻe

ʻO ke kumu mua i kaulana ai nā papa seramika i ka ʻāpana uila ʻo ko lākou hoʻonui ʻana i ka coefficient thermal maikaʻi loa. He mea maikaʻi e hoʻomaopopo i ka hoʻoili ʻana o ka wela kumu seramika e like me ke silika a hiki ke hana ma ke ʻano he mea pili. Ma waho aʻe, hiki iā ʻoe ke hoʻohana iā ia ma ke ʻano he isolator. No laila, ʻoi aku ka nui o ka hoʻohana ʻana no nā waiwai wela o nā papa seramika, ʻoiai i nā kūlana ʻino.

Paʻa

ʻO ka noi ʻana o ka ceramic e lawe mai i kahi mana dielectric paʻa, a hiki iā ʻoe ke hoʻololi i ke koena i kahi poho radiofrequency hapa e hoʻonui ai i ka mana o kāu hāmeʻa. Eia nō naʻe, ʻoiai ka paʻakikī o ka ʻili, hele mai nā mea seramika me kahi kūʻē kūʻokoʻa kūʻē i ka erosion kemika. Hiki ke ho'ololi ke kū'ē kemika o Ceramic i ke kū'ē i ka wai a me ka makū.

ʻAno ʻano

Hiki iā ʻoe ke hana i kekahi mau hihia hoʻohana e hoʻohui i kahi papa metala me ka hoʻonui wela kiʻekiʻe. Ma waho aʻe, hiki iā ʻoe ke hoʻololi i ke kumu metala i mau conductors hilinaʻi me ka hoʻohana ʻana i ke ʻano sintering. No laila, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka PCB ceramic ma muli o kona kiʻekiʻe o ka hoʻoili ʻana.

Ka lōʻihi

Hoʻokumu ke kaʻina hana papa ceramic i ka lōʻihi ma o ka hoʻohana ʻana i nā waiwai kūikawā, e like me ka paʻakikī. ʻO ia ka mea e pale ai i kāu PCB mai ka lole a me ka waimaka. No laila hiki iā ʻoe ke hilinaʻi ʻaʻole ʻoe e hoʻololi koke i kāu PCB ma muli o kona hiki ke ʻelemakule lohi. Eia kekahi, ʻo ke kūpaʻa wela kiʻekiʻe o ka PCB ceramic e manaʻo ai i kahi kaʻina decomposition decelerated.

Hiki ke hoʻololi

ʻO ka mea hope loa, hiki i ka hoʻohana ʻana i nā cores metala ke lawelawe ma ke ʻano he mea hiki ʻole ke hāʻawi i ka paʻakikī mechanical. He mea maʻalahi kēia waiwai i ka hoʻohana ʻana i nā PCB seramika i kēlā me kēia kūlana o ka mea ma muli o ke kūpaʻa kiʻekiʻe i ka corrosion a me ka lole maʻamau a me ka waimaka.

ʻO nā pono o ka PCB keramika

ʻO ka dissipation wela ka pōmaikaʻi nui i loaʻa i ka ceramic ma mua o nā mea maʻamau e like me FR-4 a me ka PCB metala. No ka mea, ua hoʻokomo ponoʻia nā mea ma luna o nā papa, aʻaʻohe wahi kaʻawale,ʻoi aku ka maikaʻi o ka holoʻana o ka wela ma o nā papa. Eia kekahi, hiki i nā mea ceramic ke pilikia mai nā mahana hana kiʻekiʻe (a hiki i 350 ° C), he aha ka mea ʻoi aku, he haʻahaʻa haʻahaʻa haʻahaʻa o ka hoʻonui wela (CTE), e ʻae ana i nā koho hoʻohālikelike hou no ka hoʻolālā PCB.

Hoʻohālikelike ʻia me nā PCB kuʻuna nona nā mea substrate he epoxy glass fiber, polyimide, polystyrene a me ka resin phenolic, nā PCB seramika e hōʻike ana i kēia mau waiwai:

ʻOi aku ka maikaʻi o ka thermal conductivity

E pale i ka ʻinoʻino

ʻO ka ikaika mechanical kūpono

E maʻalahi ka hoʻokō ʻana i ka ʻimi ʻana kiʻekiʻe

ʻO ka hoʻohālikelike ʻāpana CTA

ʻO ka helu hope

ʻO nā PCB kuʻuna i hui pū ʻia me nā substrates hoʻokumu organik e holomua ana i kekahi ʻano nui, hilinaʻi kiʻekiʻe, pololei maikaʻi, a me ka lōʻihi me ka hoʻokomo ʻana o ka ʻenehana chip i ka ʻoihana uila. ʻO nā papa kaapuni seramika he ʻano hou o ka PCB e loaʻa ana i ka hanohano i ka ʻoihana uila ma muli o ko lākou ʻano ʻokoʻa.

Hāʻawi nā Ceramic PCB i nā pono he nui ma mua o nā papa maʻamau. ʻOi aku ka maʻalahi o nā PCB Ceramic, ʻoi aku ka paʻakikī, a ʻoi aku ka maikaʻi o ka hana ma mua o nā papa kaapuni maʻamau ma muli o kā lākou conductivity wela a me ka coefficient hoʻonui haʻahaʻa (CTE). Manaʻo nā ʻenekinia ʻo kēia mau PCB ke koho maikaʻi loa no ka hoʻoemi ʻana i nā hāmeʻa uila ʻoki ʻoki. Lana ka manaʻo, ua loaʻa iā ʻoe ka manaʻo e pili ana pehea e ʻike ai i ka PCB Ceramic maikaʻi loa a hiki iā ʻoe ke koho i ka mea maikaʻi loa no ʻoe.
