Wehe i nā mea pohihihi o nā papa PCB

I kēia au kikohoʻe, kahi e hoʻololi wikiwiki nei ka holomua ʻenehana i ko kākou ola, ʻo nā papa kaapuni paʻi (PCB boards) ke kuleana koʻikoʻi i ka hoʻomohala ʻana a me ka hana o nā mea uila.Mai nā smartphones a me nā laptops i nā mea lapaʻau a me nā ʻōnaehana kaʻa, ʻo nā papa PCB nā poʻe koa ʻike ʻole e hoʻopili a mana i kēia mau mea, e hiki ai ke hoʻololi i ka ʻike.Ma kēia blog, e ʻimi mākou i nā mea kupanaha o nā papa PCB, ko lākou koʻikoʻi i ka uila uila hou, a me kā lākou mau noi like ʻole i nā ʻoihana like ʻole.

ʻO ka ulu ʻana o nā papa PCB.

Ua hele lōʻihi nā papa PCB mai ko lākou hoʻomaka ʻana i nā makahiki 1940.ʻO kēia mau hoʻomaka mua ʻana o nā papa papa hoʻokahi me nā hana liʻiliʻi e hiki ke kākoʻo wale i ka lima o nā ʻāpana.Eia nō naʻe, me ka holomua o ka ʻenehana, ʻo ka hoʻomohala ʻana i nā papa ʻaoʻao ʻelua, multi-layer, a me nā papa PCB maʻalahi i lawe mai i nā loli kipi i ka ʻoihana uila.Ua hoʻonui ʻia kēia mau hoʻomaikaʻi ʻana i ka maʻalahi o nā mea uila, nā hoʻolālā paʻa, a me ka hoʻomaikaʻi ʻana i ka hana.

Nā hiʻohiʻona a me nā ʻāpana.

E like me ka iwi kuamoʻo o nā mea uila, hāʻawi nā papa PCB i kahi kahua no ka hoʻopili ʻana i nā ʻāpana uila like ʻole.Hoʻokomo ʻia nā kaʻapuni hoʻohui ʻia (IC), nā mea pale, nā capacitors, a me nā mea uila ʻē aʻe ma ka papa PCB e hana i kahi ʻōnaehana paʻa a hoʻonohonoho ʻia.Hoʻolālā maikaʻi ʻia nā pilina ma waena o nā ʻāpana a hoʻopaʻa ʻia i loko o ka papa kaapuni e hōʻoia i ka lawe ʻana i nā hōʻailona uila a me ka ʻikepili.

Nā noi hana kea.

Loaʻa i nā papa PCB kahi ākea o nā noi a komo i loko o nā ʻāpana āpau o ko mākou ola.I ka honua o nā mea kūʻai uila, ʻo nā papa PCB ke kumu no ka hana ʻana i nā smartphones, papa, consoles pāʻani, televise, a me nā mea ʻē aʻe he nui a mākou e hoʻohana ai i kēlā me kēia lā.Ke hilinaʻi nei ka ʻoihana kaʻa i nā papa PCB no nā hana like ʻole e like me nā ʻāpana hoʻokele engine, nā ʻōnaehana anti-lock braking, a me nā ʻōnaehana hoʻokele.Loaʻa ka lāʻau lapaʻau mai nā papa PCB ma ke ʻano o ka pacemakers, nā mīkini MRI, a me nā mea mālama ola ʻē aʻe.Eia kekahi, hoʻohana ʻia nā papa PCB i ka ʻoihana aerospace, pale a me ke kelepona e hōʻoia i ka hana maʻalahi o nā ʻōnaehana koʻikoʻi a me nā ʻoihana kamaʻilio.

Nā pōmaikaʻi a me nā mea hou e hiki mai ana.

Hāʻawi nā papa PCB i nā pono he nui e hoʻolilo iā lākou i ʻāpana koʻikoʻi o ka uila uila hou.ʻO kā lākou nui compact a me nā waiwai māmā e hoʻomaikaʻi i ka pono o ka lewa a me ka lawe ʻana, ʻoi aku hoʻi i ka hihia o nā polokalamu kelepona.Hōʻike nā papa PCB i ka hilinaʻi maikaʻi loa, ka lōʻihi, a me ke kūʻē ʻana i nā mea kūlohelohe e like me ka wela a me ka haʻahaʻa.Hoʻohui ʻia, ʻo nā holomua e like me nā PCB maʻalahi e hoʻokaʻawale i ke ala no ka ʻenehana hiki ke hoʻohana ʻia, nā hōʻike hikile, a me nā mea lapaʻau implantable.Ke hoʻomau nei ka ʻenehana, e liʻiliʻi nā papa PCB, ʻoi aku ka maikaʻi, a hiki ke mālama i nā ʻōnaehana paʻakikī.

Ke noʻonoʻo nei mākou i nā mea kupanaha o ke au uila hou, ʻike maopopo ʻia ʻo nā papa PCB ka poʻe koa ʻike ʻole i kuleana no ka hana ʻole o nā mea uila.ʻO kā lākou versatility, hilinaʻi a me ka micro-complexity e hoʻolilo iā lākou i mea pono i nā ʻoihana like ʻole.I ka wā e hiki mai ana, manaʻo ʻia ka ʻenehana PCB e lawe mai i nā mea hou aʻe, hoʻololi hou i ko mākou honua, a wehe i nā mea hou.
