PCB lalolagi atinaʻe talaʻaga ma Saina atinaʻe talaʻaga | YMSPCB

Lalolagi PCB Atinae Talafaʻasolopito

O laupapa lolomi lolomi na muaʻi faʻaaogaina i masini leitio i le 1936 e le Austrian Paul Eisler, le latou foafoa.

I le 1943, tele Amerika faʻaaoga le tekonolosi i le militeri leitio.

I le 1947, NASA ma THE American Bureau of Standards na amataina le uluaʻi polokalame faʻapitoa i luga ole PCB.

I le 1948, na aloaʻia aloaʻia ai le mea fou i le Iunaite Setete mo pisinisi.

I le amataga o le 1950s, o faʻafitauli o le malosi o le pipiʻi ma le faʻamamaina o le tali a le COPPER Faila ma le faʻamalamalamaga o le CCL na fofoina, faatasi ai ma le mautu ma le faʻatuatuaina faʻatinoga, ma o le tele-fua alamanuia gaosiaina na faʻamalosia. Apamemea foil etching avea ma autu o PCB gaosiga tekonolosi, ma tasi vaega faʻatulagaina amataina.

I le 1960s, o le pu metallized lua-itu PCB na iloa ma faʻateleina gaosiga na iloaina.

I le 1970s, tele-layer PCB atiaʻe vave, ma faifai pea atiaʻe i le itu o maualuga maualuga, maualuga density, laina lelei pu, maualuga faʻatuatuaina, maualalo tau ma otometi faʻaauauina gaosiga.

I le 1980s, luga tiʻetiʻe lomia laupapa (SMT) suia malie plug-i PCB ma avea ma autu o le gaosiga.

Talu mai le 1990s, luga mounting ua atili atinaeina mai mafolafola afifi (QFP) i spherical seti afifi (BGA).

Talu mai le amataga o le 21st seneturi, maualuga-density BGA, malamala tulaga afifiina ma tele-malamala module afifi lolomi laupapa faʻavae i luga o meaola laminate mea ua atiina ae vave.

Talaʻaga o le PCB i Saina

I le 1956, Saina amata atiaʻe PCB.

I le 1960s, faaputuga gaosiga o le tasi laulau, laʻititi faaputuga gaosiga o lua-itu aʻoga ma amata ona atiaʻe multilayer laupapa.

I le 1970s, ona o tapulaʻa o tulaga faʻasolopito i lena taimi, o le faifai lemu atinaʻe o PCB tekonolosi faia le atoa gaosiga tekonolosi pa'ū i tua o le alualu i luma tulaga i fafo.

I le 1980s, alualu i luma laina gaosiga o le tasi itu, faʻalua itu ma tele-vaega lolomi laupapa na faʻalauiloa mai fafo, lea na faʻaleleia ai le tekonolosi gaosiga tulaga o lolomi laupapa i Saina

I le 1990s, tagata mai fafo PCB gaosi mai Hong Kong, Taiwan ma Iapani na o mai i Saina e faatuina soʻoga pisinisi ma atoa umiaina falegaosimea, faia Saina PCB galuega faatino ma tekinolosi alualu i luma vave.

I le 2002, na avea ma lona tolu sili ona tele gaosi PCB.

I le 2003, o le galuega faatino taua ma le faaulufaleina ma auina atu i fafo voluma o PCB sili atu $ 6 piliona, sili atu i le Iunaite Setete mo le taimi muamua ma avea ma le lona lua aupito tele PCB gaosi i le lalolagi. O le tau o galuega faatino na siitia foi mai le 8.54% i le 2000 i le 15.30%, toeititi faaluaina.

I le 2006, na oʻo atu Saina ia Iapani o se sili ona tele PCB gaosi oloa i galuega faatino faʻatauaina ma le sili ona tekonolosi toaaga atunuʻu.

I tausaga talu ai nei, Saina PCB alamanuia na tausia se maualuga tuputupu ae fua faatatau e uiga i le 20%, sili atu maualuga nai lo le tuputupu ae fua faatatau o le lalolagi PCB alamanuia!
