Amateka yiterambere ryubuyobozi bwa PCB

Kuva ivukaUbuyobozi bwa PCB, yateye imbere mu myaka irenga 70.Mubikorwa byiterambere byimyaka irenga 70, PCB yagize impinduka zingenzi, zateje imbere iterambere ryihuse rya PCB kandi bituma ikoreshwa muburyo butandukanye.Mu mateka yiterambere ya PCB, irashobora kugabanywamo ibihe bitandatu.

(1) Itariki y'amavuko ya PCB.PCB yavutse 1936 kugeza mu mpera za 1940.Mu 1903, Albert Hanson yabanje gukoresha igitekerezo cy '"umurongo" maze awukoresha kuri sisitemu yo guhinduranya terefone.Igishushanyo mbonera cyiki gitekerezo ni ugukata icyuma cyoroshye mu cyuma cyumuzunguruko, hanyuma ukagihambira ku mpapuro za paraffin, hanyuma ukabishyiraho urupapuro rwitwa paraffin, bityo ugakora prototype yuburyo bwa PCB yubu.Mu 1936, Dr. Paul Eisner yahimbye rwose ikoranabuhanga ryo gukora PCB.Iki gihe gikunze gufatwa nkigihe cyo kuvuka kwa PCB.Muri iki gihe cyamateka, uburyo bwo gukora bwakoreshejwe kuri PCB nuburyo bwo gutwikira, uburyo bwo gutera, uburyo bwo kubika vacuum, uburyo bwo guhumeka, uburyo bwo kubika imiti nuburyo bwo gutwikira.Icyo gihe, PCB yakoreshwaga mubakira radio.

(2) Igihe cyo gukora igeragezwa rya PCB.Igihe cyo kugerageza PCB cyari mu myaka ya za 1950.Iterambere rya PCB, kuva 1953, inganda zikora ibikoresho byitumanaho zatangiye kwita cyane kuri PCB zitangira gukoresha PCB ku bwinshi.Muri iki gihe cyamateka, inzira yo gukora PCB nuburyo bwo gukuramo.Uburyo bwihariye nugukoresha umuringa wambaye umuringa wuzuye impapuro zishingiye kuri fenolike resin laminate (ibikoresho bya PP), hanyuma ugakoresha imiti kugirango ushongeshe umuringa udakenewe, kugirango umuringa usigaye ube umuzenguruko.Muri iki gihe, imiterere yimiti yumuti wangirika ukoreshwa kuri PCB ni chloride ferric.Igicuruzwa gihagarariwe ni radiyo yimodoka ya transistor ikorwa na Sony, ikaba PCB igizwe numurongo umwe hamwe na PP substrate.

(3) Ubuzima bwingirakamaro bwa PCB.PCB yakoreshejwe mu myaka ya za 1960.Kuva mu 1960, amasosiyete y'Abayapani yatangiye gukoresha ibikoresho fatizo bya GE (imyenda y'ibirahuri yambaye umuringa epoxy resin laminate) ku bwinshi.Mu 1964, isosiyete ikora amashanyarazi y’Abanyamerika yateje imbere igisubizo cy’umuringa utagira amashanyarazi (cc-4 igisubizo) ku muringa uremereye, bityo gitangira uburyo bushya bwo kongera uburyo bwo gukora.Hitachi yashyizeho ikoranabuhanga rya cc-4 kugirango rikemure ibibazo byo gushyushya ibintu byahinduwe no kwambura umuringa ibikoresho bya Ge byo mu rugo mu ntangiriro.Hamwe niterambere ryambere ryikoranabuhanga ryibikoresho, ubwiza bwibikoresho fatizo bikomeje gutera imbere.Kuva mu 1965, bamwe mubakora uruganda batangiye gukora cyane Ge substrates, Ge substrate kubikoresho bya elegitoroniki yinganda na PP substrate kubikoresho bya elegitoroniki bya gisivili mubuyapani.
