Hana ʻia nā Papa Kaapuni Ceramic: He aha nā mea i hoʻohana ʻia?

Ma kēia pou blog, e ʻimi mākou i nā mea nui i hoʻohana ʻia i ka hana ʻana i nā papa kaapuni seramika a kūkākūkā i ko lākou koʻikoʻi no ka hoʻokō ʻana i ka hana maikaʻi loa.

I ka hana ʻana i nā papa kaapuni seramika, he mea koʻikoʻi nā ʻano mea like ʻole i ka hōʻoia ʻana i kā lākou hana a me ka hilinaʻi. ʻO nā papa kaapuni seramika, i ʻike ʻia he ceramic printed circuit boards (PCBs), ua hoʻohana nui ʻia i nā ʻoihana like ʻole me ka uila, aerospace a me ka automotive ma muli o kā lākou conductivity thermal maikaʻi loa, kiʻekiʻe o ka hana wela a me nā waiwai uila.

Hoʻokumu nui ʻia nā papa kaapuni seramika me ka hui pū ʻana o nā mea seramika a me nā metala, i koho pono ʻia e hoʻokō i nā koi kikoʻī o nā noi like ʻole.

1. ʻO ka pāpaʻi seramika:

ʻO ke kumu o kahi papa kaapuni seramika ka substrate seramika, kahi e hāʻawi ai i ke kumu no nā mea ʻē aʻe a pau. ʻO ka alumini oxide (Al2O3) a me ka alumini nitride (AlN) ka mea maʻamau i hoʻohana pinepine ʻia. Loaʻa i ka alumina ka ikaika mechanical maikaʻi loa, ka conductivity thermal kiʻekiʻe a me ka insulation uila maikaʻi, e kūpono ana ia no ka nui o nā noi. ʻO ka alumini nitride, ma ka ʻaoʻao ʻē aʻe, hāʻawi i ka conductivity thermal maikaʻi loa a me nā waiwai hoʻonui wela, e kūpono ana ia no nā noi e koi ana i ka hoʻoheheʻe wela kūpono.

2. Meheu conductive:

Aia ke kuleana o nā ʻōuli conductive no ka lawe ʻana i nā hōʻailona uila ma waena o nā ʻāpana like ʻole ma ka papa kaapuni. I nā papa kaapuni seramika, hoʻohana ʻia nā mea hoʻokele metala e like me ke gula, ke kālā, a i ʻole ke keleawe e hana i kēia mau ʻano. Ua koho ʻia kēia mau metala no kā lākou conductivity uila kiʻekiʻe a me ka hoʻohālikelike ʻana me nā substrate seramika. Makemake nui ʻia ke gula no kona kūpaʻa ʻana i ka corrosion maikaʻi loa a me nā waiwai uila paʻa, ʻoi aku hoʻi i nā noi kiʻekiʻe.

3. Papa dielectric:

He mea koʻikoʻi nā papa dielectric i ka insulating conductive traces a me ka pale ʻana i ka interference signal a me nā pōkole pōkole. ʻO ka mea dielectric maʻamau i hoʻohana ʻia i nā papa kaapuni seramika he aniani. Loaʻa i ke aniani nā waiwai insulating uila maikaʻi loa a hiki ke waiho ʻia ma ke ʻano he ʻāpana lahilahi ma nā substrate seramika. Eia kekahi, hiki ke hoʻopilikino ʻia ka papa aniani e loaʻa i kahi waiwai mau dielectric kikoʻī, e ʻae i ka mana pololei o nā waiwai uila o ka papa kaapuni.

4. Solder mask a me ka lapaʻau ili:

Hoʻopili ʻia ka mask solder ma luna o nā traces conductive e pale aku iā lākou mai nā mea kūlohelohe e like me ka lepo, ka wai, a me ka oxidation. Hana ʻia kēia mau masks mai ka epoxy a i ʻole polyurethane-based material e hāʻawi i ka insulation a me ka pale. E hoʻohana i nā lāʻau lapaʻau e like me ka pahu immersion a i ʻole ka uhi gula no ka hoʻomaikaʻi ʻana i ka solderability o ka papa a pale i ka oxidation o nā meheu keleawe i ʻike ʻia.

5. Via hoopiha mea:

ʻO Vias nā puka liʻiliʻi i wili ʻia ma ka papa kaapuni e hiki ai ke hoʻopili uila ma waena o nā papa like ʻole o ka papa. I nā papa kaapuni seramika, hoʻohana ʻia nā mea hoʻopiha e hoʻopiha i kēia mau lua a hōʻoia i ka conductivity uila hilinaʻi. ʻO nā mea maʻamau ma o ka hoʻopiha ʻana i nā mea hoʻopihapiha me nā pastes conductive a i ʻole nā ​​​​mea hoʻopihapiha i hana ʻia me ke kālā, keleawe a i ʻole nā ​​​​mea metala ʻē aʻe, i hui pū ʻia me ke aniani a i ʻole nā ​​​​mea hoʻopiha ceramic. Hāʻawi kēia hui i ka paʻa uila a me ka mechanical, e hōʻoia ana i kahi pilina ikaika ma waena o nā papa like ʻole.

Ma ka hōʻuluʻulu

ʻO ka hana ʻana o nā papa kaapuni seramika e pili ana i ka hui pū ʻana o nā mea seramika, metala a me nā mea kūikawā ʻē aʻe. Hoʻohana ʻia ka alumini oxide a me ka nitride aluminika ma ke ʻano he substrates, aʻo nā metala e like me ke gula, ke kālā a me ke keleawe e hoʻohana ʻia no nā ala conductive. Hana ke aniani ma ke ʻano he mea dielectric, e hāʻawi ana i ka insulation uila, a me ka epoxy a i ʻole polyurethane solder mask e pale i nā ala conductive. Hoʻokumu ʻia ka pilina ma waena o nā papa ʻokoʻa ma o kahi mea hoʻopiha piha i loko o ka conductive paste a me nā mea hoʻopihapiha.

ʻO ka hoʻomaopopo ʻana i nā mea i hoʻohana ʻia i ka hana ʻana i nā papa kaapuni seramika he mea koʻikoʻi ia no nā ʻenekinia a me nā mea hoʻolālā e hoʻomohala i nā mea uila pono a hilinaʻi. ʻO ke koho ʻana i nā mea kūpono e pili ana i nā koi noi kikoʻī e like me ka conductivity thermal, nā waiwai uila a me nā kūlana kaiapuni. Ma ka hoʻohana ʻana i nā waiwai kūʻokoʻa o kēlā me kēia mea, hoʻomau nā papa kaapuni seramika e hoʻololi i nā ʻoihana like ʻole me kā lākou hana ʻoi aku ka maikaʻi a me ka lōʻihi.
