Taariikhda Horumarinta PCB

Looxyada wareegsan ee daabacan waxaa markii ugu horeysay loo adeegsaday aaladaha raadiyaha 1936-kii Austrian-ka Paul Eisler, abuurahoodii.

Sannadkii 1943, dad badan oo Mareykan ah ayaa tiknoolojiyadda u adeegsaday raadiyaha milateriga.

Sannadkii 1947, NASA iyo THE Bureau of Standards waxay bilaabeen dood cilmiyeedkii ugu horreeyay ee farsamo ee PCB.

Sanadkii 1948, Hal-abuurka waxaa si rasmi ah looga aqoonsaday Mareykanka adeegsi ganacsi.

Horaantii 1950-meeyadii, dhibaatooyinka isku dhejinta adkaynta iyo iska caabinta alxanka ee 'COPPER Foil' iyo laminate-ka CCL ayaa la xaliyay, iyadoo la la yimid waxqabad xasiloon oo la isku halleyn karo, iyo wax soo saar warshadeed oo baaxad leh ayaa la ogaaday. Farsamaynta naxaasta biraha ayaa noqotay midda guud ee teknolojiyadda wax soo saarka PCB, isla markaana wax soo saar hal guddi ah ayaa la bilaabay.

Sannadihii 1960-meeyadii, godka metallized ee PCB-ga laba-geesoodka ah ayaa la ogaaday oo wax-soo-saar ballaaran ayaa la ogaaday.

Sanadihii 1970-yadii, PCB-lakabyo badan ayaa si dhakhso leh u kobcay, oo si isdaba-joog ah loogu horumariyey jihada saxsanaanta sare, cufnaanta sare, daloolka khadka ganaaxa, isku halaynta sare, kharash yar iyo wax soo saarka tooska ah ee otomaatiga ah.

Sanadihii 1980-meeyadii, dusha sare ee dusha sare lagu daabacay (SMT) tartiib tartiib ah ayaa loogu beddelay PCB-ga kumbuyuutarka oo wuxuu noqday midka guud ee wax soo saarka.

Laga soo bilaabo 1990-meeyadii, kor u qaadista dusha ayaa ka sii soo korodhay baakadka fidsan (QFP) ilaa xirmooyinka xariiqda wareega ah (BGA).

Laga soo bilaabo bilowgii qarniga 21aad, BGA-cufnaanta sare, baakadaha heerka jajabyada iyo qalabka wax lagu duubto ee badan oo la daabacay oo ku saleysan walxaha laminate-ka ayaa si dhakhso leh u horumaray.

Taariikhda PCB ee Shiinaha

Sanadkii 1956, Shiinaha wuxuu bilaabay inuu horumariyo PCB.

Sanadihii 1960-meeyadii, soosaarid dufcadeed oo hal guddi ah, soosaarid dufcad yar oo iskuul laba-gees leh waxayna bilaabeen inay soo saaraan guddi isku dhaf ah.

1970-yadii, xaddidnaanta xaaladaha taariikhiga ah ee xilligaas, horumarka gaabiska ah ee teknolojiyadda PCB wuxuu ka dhigay in tiknoolijiyada wax soo saarka oo dhan ay ka dambeyso heerka shisheeye ee horumarsan.

1980-yadii, khadadka waxsoosaarka ee horumarsan ee hal dhinac ah, labada dhinac iyo lakab badan oo daabacan ayaa laga soo saaray dibadda, taas oo hagaajisay heerka tiknoolajiyada wax soo saarka ee guddiga daabacan ee Shiinaha

Sagaashameeyadii, soo saarayaasha ajaanibta PCB ee ka kala yimid Hong Kong, Taiwan iyo Japan ayaa u yimid Shiinaha si ay u aasaasaan hawlo wada jir ah iyo warshado wada leh, taas oo ka dhigaysa wax soo saarka PCB-ga Shiinaha iyo teknolojiyadda si deg deg ah.

Sannadkii 2002, waxay noqotay shirkadda saddexaad ee wax soo saar PCB.

Sanadkii 2003, qiimaha wax soosaarka iyo mugga soo dejinta iyo dhoofinta PCB wuxuu naga dhaafay $ 6 bilyan, isagoo dhaafay Mareykanka markii ugu horreysay wuxuuna noqday kan labaad ee ugu wax soo saarka badan PCB adduunka. Qiimaha wax soo saarku sidoo kale wuxuu ka kordhay 8.54% sanadkii 2000 ilaa 15.30%, ku dhowaad wuu labanlaabmay.

Sannadkii 2006, Shiinaha ayaa Japan kala wareegtay waddanka ugu wax soo saarka badan PCB adduunka xagga wax soo saarka iyo waddanka ugu firfircoon xagga farsamada.

Sanadihii la soo dhaafay, Shiinaha PCB warshadaha ayaa ilaaliyay heerka koritaanka sare ee ku saabsan 20%, aad uga sarreeya heerka koritaanka warshadaha PCB-da adduunka!
