Nyob rau hauv xyoo tsis ntev los no, nrog lub ntiaj teb no kev lag luam electronics hloov mus rau Tuam Tshoj, lub hom phiaj ntawm lub tuam txhab PCB tau txav mus rau mainland. Hauv yav dhau los, ntiaj teb PCB cov khoom tsim muaj 70 feem pua hauv teb chaws Europe, Asmeskas (feem ntau North America), Nyiv thiab lwm yam peb cheeb tsam.
Nrog rau kev hloov mus rau qhov chaw muaj peev xwm ntxiv, cov teb chaws Es Xias tau dhau los ua ib qho tseem ceeb thoob ntiaj teb PCB muab lub hauv paus, nrog rau tag nrho cov nqi tso tawm ze li 90% ntawm lub ntiaj teb tag nrho, thiab Tuam Tshoj tau dhau los ua ib lub chaw PCB.
Raws li cov ntaub ntawv qhia txog Prismark, lub teb chaws tus nqi PCB tau nce tawm ntawm 41.2 billions nyiaj hauv xyoo 2009 mus rau 58,8 billions USD, nrog rau qhov nruab nrab xyoo kev loj hlob ntawm 4.55%. Nyob rau hauv 2017, Tuam Tshoj tus PCB tso tawm tus nqi mus txog 29.732 billion US dollars, accounting rau ntau tshaj 50% ntawm lub ntiaj teb tag nrho cov nqi tso tawm.
Raws li "leej niam cov khoom hluav taws xob", PCB plays lub luag haujlwm ua haujlwm hauv kev lag luam, thiab nws daim teb daim ntawv ntim qis heev heev. Kev lig kev cai, kev sib txuas lus, khoos phis tawj, thiab cov khoom siv tshuab hluav taws xob yog cov tswv yim tseem ceeb ntawm cov ntawv thov PCB. Tam sim no nrog txoj kev tsim hluav taws xob tshuab hluav taws xob thiab kev nce qib ntawm 5G kev tsim kho, nws yuav tsum tsav cov khoom PCB kom nce ntim hauv ob xyoos tom ntej.
