ʻO ka BB waihoʻoluʻu P ʻoluʻolu, i ʻike mau ʻia ʻo Flex PCB, he kiʻiʻoniʻoni polyimide insulating a me ke ʻano kaapuni paʻi. ʻO nā polyimides nā insulators, no laila hiki ke hoʻopau ʻia ke ala inā he conductive ke ʻano kaapuni. E like me ka “weld mask” o kahi PCB paʻa, ua uhi ʻia kahi PCB maʻalahi me kahi “overlay” ʻeleʻele e hoʻokaʻawale i ke kaapuni mai kekahi pilikia electromagnetic. Kūleʻa ʻo Flex PCB i kēia manawa i nā polokalamu kelepona a me nā noi olakino, keu hoʻi ke hoʻololi ʻia nā kaapuni i nā loli wela keu a koe ka maʻalahi.

Manaʻo ʻia ʻo PCBS maʻalahi no nā kumu like ʻole. ʻO ka mea maopopo loa, hiki ke hoʻoponopono ʻia kā lākou circuitry e hoʻohālikelike i ka huahana ponoʻī. He mea maikaʻi loa kēia i ka wā e pili ana i nā palena e like me ka hoʻomau, ka lōʻihi, ke kaumaha haʻahaʻa a me ka maʻalahi. ʻAʻole hiki i nā papa kaapuni kuʻuna ke hoʻokō i nā kūlana like o ka lōʻihi, palupalu a me ka pono.

ʻOi aku ka maikaʻi o nā papa maʻalahi ma mua o nā papa paʻa kuʻuna i ka wā e pili ana i nā palena huahana. No ka laʻana, ʻo ka hoʻohana ʻana i kahi PCB maʻalahi ma kahi o kahi mea paʻa hiki ke hōʻemi nui i ka nui o ka huahana. Hiki iā lākou ke kūlou a hoʻohuli e hoʻomaʻa i ka huahana kumu. Hiki ke maʻalahi ka huahana holoʻokoʻa me ka hoʻohana ʻana i nā ʻāpana like me nā mea paʻa a kaumaha. However, flexible plates are not completely flexible. Loaʻa i kēia mau PCBS kekahi mau wahi paʻa, akā ua kau ʻia ka circuitry ma nā ʻāpana maʻalahi, no laila hiki ke hoʻoponopono ʻia e like me ka huahana. E mālama i nā ʻāpana ʻoʻoleʻa i hoʻohana ʻia no ke kākoʻo waiwai no laila e mālama ʻia i ka pae haʻahaʻa loa.

1. ? ieoaeunoai:

Hiki ke kūkulu ʻia kahi PCB maʻalahi e like me kona rigidity ma nā ʻano like ʻole. Wahi a nā ʻenehana, pae a me nā mea, hoʻokaʻina mākou iā lākou penei:

Hoʻokahi ʻaoʻao hikiwawe kaapuni (SSFC) i loko o kahi papa conductive hoʻokahi me ka metala a i ʻole ka polymer piha metala ma kahi kiʻiʻoniʻoni dielectric maʻalahi; ʻO ka polyimide maʻamau, hoʻohana ʻo ia i ka mīkini THT (ma loko o ka puka) e kau ai i ka ʻāpana, ʻo ia ka mea hiki iā ʻoe ke hoʻohana i kekahi ʻaoʻao e hoʻoponopono a hoʻololi i ka ʻāpana. Hiki ke hana ʻia me ka hoʻohana ʻana i kahi kiʻiʻoniʻoni insulating PCB ʻaoʻao hoʻokahi me ka ʻole o ka pale pale; Eia nō naʻe, ʻo ka hoʻohana ʻana i kahi pale pale ma ke kaapuni ka hana maʻamau no ka mea hiki ke pale i ka mīkini a me kekahi EMI. The structure and insulation of a single-layer flexible PCB are explained as follows:

ʻO kahi PCB maʻalahi hiki ke hoʻopili ʻia he wahi ʻoluʻolu o PCB maʻalahi, pili ka hana hou o kēia manawa i kahi ʻano hana maʻalahi hiki ke hoʻopuka i kahi kaapuni maʻalahi me nā alakaʻi keleawe o ka lahilahi ma kona lōʻihi. The conductor is thinner in the flexible region and thicker in the rigid region. This method involves selective etching of copper foil to obtain depth in various areas of the circuit.

Ua koho pinepine ʻia ke kālai ʻana i nā ʻenehana PCB maʻalahi e hoʻohua i nā pilina metala ʻole e hiki ai. Hoʻonui ʻia mai ka ʻaoʻao a hiki i ka pili plug-in. Hoʻonui ka wahi i hoʻonui ʻia i nā hono paʻa a paʻa ma mua o nā kaapuni maʻalahi.

ʻO ka PCB flexible multilayer he kaapuni maʻalahi like me nā papa he nui. Hoʻopili ʻia kēia mau papa e nā papa pālahalaha. Hoʻopili mau ʻia nā ʻāpana o kahi PCB hikiwawe-nui ma nā lua. Ua like kēia mau PCBS multilayer me ka PCBS multilayer paʻa koe wale no nā ʻano like ʻole o ka waiwai, ka maikaʻi, nā ʻano, a me ke kumukūʻai. ʻOi aku ke kumu kūʻai o nā kaʻa kaʻa maʻalahi ma mua o ko lākou mau hoa, akā e hōʻoia i ka maikaʻi. Aia ma lalo kahi hiʻohiʻona o kahi PCB multi-layer.

ʻO ka ʻāpana koʻikoʻi wale nō ka ʻāpana i hoʻohana ʻia no ka hui ʻana. ʻO ke koena o ka papa kaapuni he maʻalahi.

Hoʻohana ʻia ka PCBS maʻalahi ma nā wahi aʻe:

Hoʻohana pinepine ʻia nā papa kaapuni paʻi maʻalahi ke pono ʻia ka pono, hiki ke hoʻololi a me nā huahana māmā, e like me nā ʻano lāʻau lapaʻau. Hoʻohana ka Pill pahupaʻi kiʻi ʻoni i kapa ʻia ʻo ka Pill Cam i kahi kaapuni maʻalahi loa e pono ke hoʻokaʻawale ʻia a paʻa. Ma hope o ka ale ʻana i ka pila, hiki i nā kauka a me nā loea ke nānā pololei i kaʻiʻo mai loko o ke kino. Pono e liʻiliʻi nā pila a pono e neʻe maʻalahi i loko o ke kino, no laila he koho maikaʻi loa ka PCBS maʻalahi, ʻaʻole like me nā mea ʻoʻoleʻa a palupalu.

B) Nā kelepona akamai:

ʻO ke koi no nā kelepona “akamai” pono e hana ʻia nā mea kelepona i nā ʻāpana liʻiliʻi a me nā kaapuni maʻalahi. No laila, he hana koʻikoʻi ka PCBS maʻalahi i nā kaʻapuni i hoʻohana ʻia ma kekahi mau wahi koʻikoʻi o ke kaapuni, e like me nā “power amplifier”. No laila hiki i nā kelepona ke akamai a māmā.

C) uila uila:

ʻO nā huahana uila i loko o ka motherboard ke kumu a me ka ʻuhane o ke kamepiula hou. Pono e hoʻokō i ka hoʻolālā kaapuni i kahi ala liʻiliʻi. No laila, hoʻohana ʻia nā papa kaapuni maʻalahi no ka mālama ʻana i nā mea āpau a liʻiliʻi.
