ʻO ka hana uila uila i paʻi papa kaapuni (ma kēia hope aku i kapa ʻia PCB) hoʻohana ʻia nā huahana mai ka 1948 a hoʻomaka e puka a lilo i hoʻohana ākea ʻia i nā 1950. ʻO ka ʻoihana PCB kuʻuna kahi ʻoihana ikaika a ʻoi aku ka haʻahaʻa o kona ʻenehana ma mua o ka ʻoihana semiconductor. Mai ka hoʻomaka ʻana o 2000, ua neʻe iki ka ʻoihana semiconductor mai ka US a me Iāpana a i Taiwan a me Kina. I kēia manawa, ua lilo ʻo Kina i mea hana PCB mana i ka honua, e helu ana ma mua o 60% o ka PCB huahana o ka honua.

Lapaʻau pono:

ʻO nā holomua o kēia lā i ka ʻepekema lapaʻau no ka ulu wikiwiki ʻana o ka ʻoihana uila. ʻO ka hapa nui o nā pono lapaʻau (e laʻa, mika pH, nā mīkini helu naʻau, nā ana wela, ELECTROcardiogram / EEG, hāmeʻa MRI, X-ray, CT scans, nā hāmeʻa hoʻoikaika koko, nā pae ana o ka pae kō glucose, nā mea hoʻoulu, nā pono microbiological, a me nā mea ʻē aʻe) he pcBS -e hoʻokumu ʻia no ka hoʻohana pākahi. Kūleʻa kēia mau PCBS a loaʻa nā koina liʻiliʻi. ʻO ka manaʻo o nā sensor Density ka waiho ʻana i nā ʻāpana SMT liʻiliʻi i nā nui PCB liʻiliʻi. ʻOi aku ka liʻiliʻi o kēia mau mea lapaʻau, maʻalahi ka lawe, māmā a maʻalahi hoʻi e hana.

Nā pono hana ʻoihana.

Hoʻohana nui ʻia ʻo PCBS i ka hana ʻana, nā hale hana a me nā mea kanu e pili ana. These industries have high-power machinery driven by high-power working circuits that require large current. No ka hana ʻana i kēia, ua uhi ʻia ka papa luna o ka PCB me kahi papa keleawe mānoanoa, a ʻokoʻa ka PCBS uila paʻakikī, e lawe nei i kahi au o 100 amperes. He mea nui loa kēia i nā noi e like me ka hoʻoheheʻe arc, nā mea hoʻokele hoʻokele servo nui, nā mea hoʻoheheʻe pākiko-acid, ka maopopo ʻole o ka lole pulupulu no ka pūʻali koa ʻoihana a me nā lole.

ʻO ka kukui

I ke kukui, ke neʻe nei ka honua i nā hopena hopena ikaika. These halogen bulbs are rare now, but now we see LED lights and high-intensity leds around. Hāʻawi kēia mau leds liʻiliʻi i ke kukui ʻōlinolino kiʻekiʻe a kau ʻia ma ka PCBS ma muli o ka aluminika. Loaʻa i ka Aluminium ka waiwai o ke omo ʻana i ka wela a me ka pā ʻana i ka lewa. No laila, no ka mana kiʻekiʻe, hoʻohana mau ʻia kēia mau PCBS alumini i nā kaapuni kukui LED o nā kaapuni uila waena a me ka mana kiʻekiʻe.

Kaʻa a me ka lewa

Another application of PCBS is in the automotive and aerospace industries. ʻO kahi mea maʻamau ma aneʻi ke hoʻeaʻea mai ka lele ʻana o nā mokulele a i ʻole nā ​​kaʻa. No laila, i mea e māʻona ai kēia mau haʻalulu ikaika, e loli ka PCB.

No laila, e hoʻohana i kahi PCB i kapa ʻia ʻo Flex PCB. Hiki i ka PCB maʻalahi ke kū i ka haʻalulu kiʻekiʻe a me ke kaupaona māmā, a pēlā e hoʻemi ai i ke kaona holoʻokoʻa o ka mokulele. Hiki ke hoʻoponopono ʻia kēia mau PCBS maʻalahi i kahi ākea, a he mea maikaʻi nui nō hoʻi ia. Hana ʻia kēia PCBS maʻalahi e like me nā mea hoʻopili, interface, a hiki ke hōʻuluʻulu ʻia i nā Spaces compact, e like me nā panela ma hope, ma lalo o nā dashboard, etc. Hiki ke hoʻohana ʻia kahi hui o PCBS ʻoʻoleʻa a maʻalahi hoʻi (PCBS paʻa paʻa).

Mai ka hoʻokaʻawale ʻana o ka ʻoihana noi, ua helu ka uila uila no ka hapa nui, a hiki i 39%; Loaʻa nā kamepiula i 22%; Kamaʻilio 14%; Industrial controls and medical equipment accounted for 14 per cent; Automotive electronics accounted for 6%. ʻO ka pale a me ka aerospace ka helu no 5%, aerospace a me nā pono lāʻau a me nā māla ʻē aʻe i nā koina kiʻekiʻe no ka pololei PCB.

Hoʻohana ākea ʻo PCB no ka mea he nui nā pono kūʻokoʻa, i hiki ke hōʻuluʻulu ʻia penei.

1. Ke kiʻekiʻena kiʻekiʻe.

Me ka hoʻomaikaʻi ʻana o ka hoʻohui kaapuni hoʻohui a me ka ʻenehana hoʻokomo, hiki ke hoʻomohala i ka PCBS kiʻekiʻe-kiʻekiʻe.

2. Kūpono kiʻekiʻe.

Ma o ke kaʻina o nā loiloi, nā hoʻāʻo a me nā hoʻāʻo ʻelemakule, hiki i ka PCB ke hōʻoia ʻia e hana pono no ka manawa lōʻihi.

3. Hoʻolālā.

No nā ʻano hana PCB āpau (uila, kino, ʻumeʻa, mīkini, a pēlā aku) nā koi, hiki ke kaulike ʻia ma o ka hoʻolālā ʻana, hana maʻamau a me nā ʻano ʻē aʻe e hoʻokō ai i ka manawa hoʻolālā papa paʻi ʻia he pōkole, kiʻekiʻe maikaʻi.

4. Hoʻonui.

Ma o ka hoʻokele o kēia manawa, ke kaulike ʻana, ka pālākiō (nui), hana automation a me nā hana ʻē aʻe hiki ke hoʻokō ʻia e hōʻoia i ke kūlike o ka maikaʻi o ka huahana.

Hōʻikeʻike.

Ua hoʻokumu ʻia kahi ʻano hoʻokolohua piha, nā pae hoʻokolohua, nā pono hoʻokolohua like ʻole a me nā mea kani e hoʻāʻo a ʻike i nā huahana PCB no ke kūlike a me ke ola lawelawe.

6. Huihui.

ʻAʻole kōkua wale nā ​​huahana PCB i ka hui maʻamau o nā mea like ʻole, akā kōkua pū kekahi i ka hana aunoa a me ka lehulehu.

I ka manawa like, hiki ke ʻākoakoa PCBS a me nā ʻākoakoa o nā mea like ʻole i nā ʻāpana, nā ʻōnaehana, a i ʻole nā ​​mīkini holoʻokoʻa.

7. Mālamama.

Hoʻonohonoho ʻia nā huahana PCB a me nā hui i hoʻohui ʻia no ka mea ua hoʻolālā ʻia a hana ʻia i kahi pae hoʻohālikelike.

I kēia ala, ke pau ʻole ka ʻōnaehana, hiki ke hoʻololi koke ʻia, maʻalahi a maʻalahi hoʻi, a hoʻihoʻi wikiwiki i ka hana o ka ʻōnaehana lawelawe.
