Nyob rau kaum xyoo dhau los, PCBs thoob ntiaj teb tau txuas ntxiv rau cov tebchaws rau Asia, tshwj xeeb tshaj yog Tuam Tshoj, thiab Suav teb tau dhau los ua cov khoom siv hluav taws xob loj thiab PCB cov chaw tsim khoom. Tuam Tshoj' s kev lag luam hauv teb chaw tsim khoom thiab kev tsim khoom tau zoo tau ntxim nyiam kev nqis peev txawv teb chaws, ua rau Tuam Tshoj' s PCB kev lag luam loj hlob nyob rau hauv ntau npaug nyob rau hauv ob peb xyoos xwb.
Tam sim no, Tuam Tshoj' s PCB kev lag luam muaj plaub yam luv hauv qab no ntxiv rau nws cov txiaj ntsig tawm thiab cov muag hauv kev lag luam hluav taws xob tiv thaiv kev lag luam:
Cov khoom siv thiab kev ua lag luam nthuav dav. PCBs yog qhov kev sib txuas tseem ceeb rau cov khoom siv hluav taws xob thiab yuav tsum muaj rau txhua yam khoom siv hluav taws xob. Tshwj xeeb hauv kev tshaj xov xwm hluav taws xob tam sim no, kev ua cov ntaub ntawv thiab cov khoom siv sib txuas lus tso cov txheej txheem siab dua thiab xav tau ntau dua ntawm PCB.
Kev lag luam kev lag luam tau nthuav dav. Kev lag luam luam tawm Circuit Court tau hloov zuj zus los ntawm ib pawg thawj coj ua mus rau cov khoom siv hluav taws xob Circuit Court, suav nrog kev sib koom ua ke ntawm hluav taws xob Circuit Court thiab kev tsim cov khoom siv hluav taws xob tsim hluav taws xob (EMS). Cov ntawv luam tawm cov tuam txhab tsim yuav ua cov hluav taws xob sib dhos pabcuam raws li cov neeg siv khoom.
Cov khoom qib nce mus ntxiv. Tam sim no, cov PCBs zoo tib yam tseem siv tau rau cov khoom siv hluav taws xob dav dav, thiab lub tshuab hluav taws xob tshiab tsim hluav taws xob xav tau hluav taws xob ntau dua, uas tsim nyog rau ntau txoj haujlwm, miniaturization, thiab lub teeb yuag xav tau ntawm tag nrho cov tshuab. Mas los tsim cov pob ntau txheej, cov laug cam uas hloov tau thiab qhov chaw siab sib cuam tshuam (HDI / BUM) substrates thiab cov pob IC (BGA, CSP).
Tshuab ntau lawm yog txhim kho ntxiv. Txhawm rau txhawm rau ua kom lub siab Circuit Court phaib loj, cov txheej txheem thev naus laus zis tshiab yuav tsum muaj nyob rau hauv ntau yam xws li patterning, ua cov qhov, txheej txheej saum npoo av, thiab tshuaj ntsuam. Qhov muag tsis pom / faus thiab qhov laminate yog cov kev siv ntau. Kev tsim cov khoom tshiab rau HDI / BUM cov laug cam thiab IC pob substrates, thiab kev ua tau zoo dua hauv kev siv hluav taws xob thiab kev siv tshuab, yuav qhia ntau qhov ntawm cov khoom siv tshiab laser thiab optoelectronic automation.
Hauv 2013, Tuam Tshoj&# {{{1}}; s PCB ntau lawm tus nqi mus txog 22. 559 nphom US daus las, suav nyiaj txiag rau {{4} }. 1% ntawm lub ntiaj teb PCB cov nqi ntau lawm. Txij li ntawm 2008 mus rau 2013, qhov kev sib koom ua ib xyoos ib zaug ntawm Tuam Tshoj&# {{1}}; s PCB ntau lawm tus nqi mus txog 9. 4%, siab dua ntiaj teb kev nce qib.
Tuam Tshoj' s luam tawm pawg thawj coj saib kev lag luam kuj tseem nthuav qhia toj roob hauv pes sib tw kev sib tw. Qhov loj ntawm cov lag luam feem ntau me me, thiab cov tuam txhab PCB loj me me. Raws li CPCA cov txheeb cais, muaj txog 1, 500 PCB cov tuam txhab nyob hauv Suav teb hauv {{3}, feem ntau tau faib rau hauv Pearl River Delta, Yangtze River Delta thiab Bohai Rim cheeb tsam. Hauv {{3}}, tag nrho ntawm 50 cov lag luam loj thiab super-loj tau suav rau 3. 3% ntawm tag nrho cov tuam txhab PCB nyob hauv Suav teb loj. Cov.
