Mea Pa'i Kaapuni Maalahi | Polyimide Pcb | Pcb keleawe | Na Papa Kaapuni Soldering

Ma kēia ʻatikala, e nānā pono mākou i nā mea i hoʻohana mau ʻia i lokohana kaapuni paʻi maʻalahi.

Ua hoʻololi nui nā kaʻapuni paʻi maʻalahi (FPC) i ke kahua o ka uila. ʻO ko lākou hiki ke kūlou i mea kaulana i nā ʻoihana like ʻole me ka aerospace, automotive, mālama olakino, a me nā mea uila uila.

ʻO kekahi o nā mea nui i hoʻohana ʻia i ka hana ʻana i nā kaapuni paʻi maʻalahi he polyimide.ʻO ka Polyimide kahi polymer hana kiʻekiʻe me ke kūpaʻa wela maikaʻi loa, ka pale kemika a me ka paʻakikī mechanical. He mea kūpono kēia mau waiwai no nā kaapuni maʻalahi no ka mea hiki iā ia ke pale i nā wela kiʻekiʻe a me nā kaiapuni paʻakikī me ka ʻole o ka pili ʻana i kāna hana. Hoʻohana mau ʻia nā kiʻiʻoniʻoni polyimide ma ke ʻano he substrate no nā kaapuni paʻi maʻalahi.

Ma waho aʻe o ka polyimide, ʻo nā mea ʻē aʻe i hoʻohana pinepine ʻia i ka hana kaapuni paʻi maʻalahi he keleawe.Ua koho ʻia ʻo Copper no kāna conductivity uila maikaʻi loa, ka pale ʻana i ka corrosion a me ka ductility. Hoʻopili pinepine ʻia ka pepa keleawe lahilahi i kahi substrate polyimide e hana i ke ala conductive no ke kaapuni. Hāʻawi ka papa keleawe i nā pilina uila pono e pono ai ke kaapuni e hana pono.

No ka pale ʻana i nā ʻāpana keleawe a hōʻoia i ka lōʻihi o ke kaapuni paʻi maʻalahi, pono kahi uhi uhi a i ʻole solder mask.ʻO ka overlay kahi kiʻiʻoniʻoni hoʻopili thermoset i hoʻohana maʻamau i nā ʻili kaapuni. Hana ia ma ke ʻano he pale pale, e pale ana i nā ʻāpana keleawe mai nā mea kūlohelohe e like me ka wai, ka lepo, a me ka pōʻino kino. ʻO ka mea uhi maʻamau he kiʻiʻoniʻoni polyimide, nona ka ikaika paʻa kiʻekiʻe a hiki ke hoʻopaʻa paʻa ʻia i ka substrate polyimide.

No ka hoʻomaikaʻi hou ʻana i ka lōʻihi a me ka hana o nā kaapuni paʻi maʻalahi, hoʻohana pinepine ʻia nā mea hoʻoikaika e like me ka lipine a i ʻole nā ​​​​mea hoʻoikaika.Hoʻohui i nā mea hoʻoikaika i nā wahi kikoʻī o kahi kaapuni kahi e pono ai ka ikaika hou a i ʻole ka ʻoʻoleʻa. Hiki i kēia mau mea ke hoʻokomo i nā koho like ʻole, e like me ka polyimide a i ʻole polyester film, fiberglass, a i ʻole metala metala. Kōkua ka hoʻoikaika ʻana i ka pale ʻana i nā kaapuni mai ka haehae a haki ʻana i ka wā o ka neʻe ʻana a i ʻole ka hana.

Hoʻohui ʻia, hoʻohui ʻia nā pads a i ʻole nā ​​mea pili e hoʻomaʻamaʻa i ka pilina ma waena o ke kaapuni paʻi maʻalahi a me nā mea uila ʻē aʻe.Hana ʻia kēia mau pads mai kahi hui ʻana o nā mea keleawe a me nā mea kūʻai kūʻai. Hāʻawi nā pad hoʻopaʻa i ka interface kūpono no ke kūʻai ʻana a i ʻole ka hoʻohui ʻana i nā ʻāpana e like me nā kaapuni i hoʻohui ʻia (ICs), nā mea pale, nā capacitors, a me nā mea hoʻohui.

Ma waho aʻe o nā mea koʻikoʻi ma luna, hiki ke hoʻohui ʻia nā mea ʻē aʻe i ka wā o ka hana hana ma muli o nā koi kikoʻī.No ka laʻana, hiki ke hoʻohana ʻia nā mea hoʻopili e hoʻopaʻa i nā ʻāpana like ʻole o nā kaapuni paʻi maʻalahi. Hoʻopaʻa kēia mau mea hoʻopili i kahi paʻa ikaika a hilinaʻi hoʻi, e ʻae i ke kaapuni e mālama i kona kūpaʻa. Hoʻohana pinepine ʻia nā silicone adhesives ma muli o ko lākou maʻalahi, ke kūpaʻa wela kiʻekiʻe, a me nā waiwai paʻa maikaʻi.

Ma ke ʻano holoʻokoʻa, koho pono ʻia nā mea i hoʻohana ʻia i ka hana ʻana i nā kaʻa kaʻa paʻi maʻalahi e hōʻoia i ka hana maikaʻi loa a me ka lōʻihi.ʻO ka hui pū ʻana o ka polyimide ma ke ʻano he substrate, keleawe no ka conductivity, overlays no ka pale ʻana, nā mea hoʻoikaika no ka ikaika hoʻohui, a me nā pads no nā mea pili e hana i kahi kaapuni paʻi hiki ke hoʻohana pono ʻia. ʻO ka hiki o kēia mau kaʻapuni ke hoʻololi i nā ʻano noi like ʻole, me nā ʻaoʻao curved a me nā ākea paʻa, pono lākou i nā mea uila uila hou.

I ka hōʻuluʻulu ʻana, ʻo nā mea kaapuni paʻi maʻalahi e like me ka polyimide, copper, overlays, reinforcements, adhesives, a me nā pads nā mea nui i ka hana ʻana i nā kaapuni uila paʻa a maʻalahi.Hana pū kēia mau mea e hoʻolako i nā pili uila e pono ai, palekana a me ka ikaika mechanical e pono ai i nā mea uila o kēia mau lā. Ke hoʻomau nei ka ʻenehana, ʻoi aku ka maikaʻi o nā mea i hoʻohana ʻia i ka hana kaapuni paʻi maʻalahi, e hiki ai i nā noi hou.
