Kayan aikin lantarki da aka buga allon kewaye (anan ake kira PCB) samfuran sun kasance cikin amfanin kasuwanci tun 1948 kuma sun fara fitowa kuma sun zama masu amfani sosai a cikin shekarun 1950. Masana’antar PCB na gargajiya masana’antu ne mai yawan kuzari kuma ƙarfin fasaha ya yi ƙasa da na masana’antar semiconductor. Tun daga farkon shekarun 2000, masana’antar semiconductor ta koma sannu a hankali daga Amurka da Japan zuwa Taiwan da China. Ya zuwa yanzu, kasar Sin ta zama mai samar da PCB mai tasiri a duniya, wanda ya kai sama da kashi 60% na fitar da PCB na duniya.

Kayan aikin likita:

Ci gaban yau a kimiyyar likitanci gaba ɗaya saboda saurin haɓaka masana’antar lantarki. Yawancin na’urorin likitanci (misali, pH mita, firikwensin bugun zuciya, ma’aunin zafin jiki, ELECTROcardiogram/EEG, na’urorin MRI, X-ray, CT scans, na’urorin hawan jini, na’urorin auna matakan glucose na jini, incubators, na’urorin microbiological, da sauransu) pcBS ne -bassin don amfanin mutum. Waɗannan PCBS galibi suna da ƙima kuma suna da ƙananan daidaitattun sifofi. Na’urar firikwensin yana nufin sanya ƙananan abubuwan SMT a cikin ƙananan PCB masu girma dabam. Waɗannan na’urorin likitanci sun fi ƙanƙanta, sauƙin ɗauka, sauƙi da sauƙin aiki.

Kayan masana’antu.

Hakanan ana amfani da PCBS sosai a masana’antu, masana’antu da shuke -shuke da ke kusa. These industries have high-power machinery driven by high-power working circuits that require large current. Don yin wannan, saman rufin PCB an lulluɓe shi da kauri na jan ƙarfe, wanda, sabanin hadaddun PCBS na lantarki, yana ɗaukar nauyin har zuwa amperes 100. Wannan yana da mahimmanci musamman a aikace-aikace kamar walda arc, manyan direbobin motar servo, caja batirin gubar-acid, rashin daidaituwa da yadudduka na masana’antar soja da sutura.

Haske

A cikin haske, duniya tana tafiya zuwa mafita ingantattun makamashi. These halogen bulbs are rare now, but now we see LED lights and high-intensity leds around. Waɗannan ƙananan leds suna ba da babban haske mai haske kuma an ɗora su akan PCBS-tushen aluminium. Aluminium yana da dukiyar shan zafi da haskaka shi cikin iska. Sabili da haka, saboda babban iko, ana amfani da waɗannan PCBS na aluminium a cikin da’irar fitilar LED na madaidaiciya da madaidaiciyar madaidaiciyar da’ira.

Motoci da Aerospace

Another application of PCBS is in the automotive and aerospace industries. Dalili na gama gari anan shine reverberation daga motsi jirgin sama ko motoci. Don haka, don gamsar da waɗannan raɗaɗin ƙarfi, PCB ya zama mai sassauƙa.

Saboda haka, yi amfani da PCB da ake kira Flex PCB. PCB mai sassauƙa na iya jurewa babban girgizawa da nauyi mai sauƙi, don haka rage girman nauyin kumbon. Waɗannan PCBS masu sassaucin ra’ayi kuma ana iya daidaita su a cikin kunkuntar sarari, wanda kuma babban fa’ida ne. Waɗannan PCBS masu sassauƙa suna aiki azaman masu haɗin kai, musaya, kuma ana iya haɗa su a cikin ƙaramin Spaces, kamar bayan bangarori, ƙarƙashin dashboards, da sauransu. Hakanan ana iya amfani da haɗin PCBS mai ƙarfi da sassauƙa (PCBS mai tsauri).

Daga rarraba masana’antar aikace -aikacen, kayan lantarki masu amfani sun yi lissafin mafi girman rabo, har zuwa 39%; Kwamfutoci sun kai 22%; Sadarwa 14%; Industrial controls and medical equipment accounted for 14 per cent; Automotive electronics accounted for 6%. Tsaro da sararin samaniya sun kai 5%, sararin samaniya da na’urorin likitanci da sauran filayen suna da manyan buƙatu don daidaiton PCB.

Ana amfani da PCB sosai saboda yana da fa’idodi da yawa na musamman, waɗanda za a iya taƙaita su kamar haka.
