1. Taw qhia txog tooj liab ntawv ci
Copper foil (copper foil): ib yam khoom siv cathode electrolytic, nyias, nruam hlau ntawv tso rau ntawm lub hauv paus txheej ntawm lub rooj tsavxwm Circuit Court, uas ua raws li tus neeg xyuas pib ntawm PCB. Nws yooj yim ua raws li cov txheej txheem insulating, lees txais cov txheej txheem luam tawm, thiab tsim cov qauv Circuit Court tom qab corrosion. Copper mirror test (copper mirror test): ib qho kev ntsuam xyuas ntawm cov tshuaj tiv thaiv corrosion, siv lub tshuab nqus tsev tso rau ntawm lub iav phaj.
Copper foil yog ua los ntawm tooj liab thiab ib feem ntawm lwm cov hlau. Copper foil feem ntau muaj 90 foil thiab 88 foil, uas yog, cov ntsiab lus tooj liab yog 90% thiab 88%, thiab qhov loj yog 16 * 16cm. Copper foil yog cov khoom siv kho kom zoo nkauj tshaj plaws. Xws li: tsev so, cov tuam tsev, cov mlom Buddha, cov cim kub, pobzeb mosaics, khoom siv tes ua, thiab lwm yam.
2. Cov yam ntxwv ntawm cov khoom
Copper foil muaj cov yam ntxwv ntawm cov pa oxygen tsawg thiab tuaj yeem txuas rau ntau yam substrates, xws li hlau, insulating cov ntaub ntawv, thiab lwm yam, thiab muaj qhov kub thiab txias. Feem ntau siv hauv electromagnetic shielding thiab antistatic. Lub conductive tooj liab ntawv ci yog muab tso rau ntawm qhov chaw ntawm lub substrate thiab ua ke nrog cov hlau substrate, uas muaj zoo heev conductivity thiab muab electromagnetic shielding nyhuv. Nws tuaj yeem muab faib ua: tus kheej-nplaum tooj liab ntawv ci, ob chav ua tooj liab ntawv ci, ib leeg-ua tooj liab ntawv ci, thiab lwm yam.
Electronic qib tooj liab ntawv ci (purity saum toj no 99.7%, thickness 5um-105um) yog ib qho ntawm cov ntaub ntawv yooj yim ntawm kev lag luam hluav taws xob. Kev loj hlob sai ntawm cov ntaub ntawv hluav taws xob hauv kev lag luam, kev siv hluav taws xob qib tooj liab ntawv ci yog nce, thiab cov khoom siv dav siv hauv cov tshuab xam zauv, Cov khoom siv sib txuas lus, QA cov cuab yeej, lithium-ion roj teeb, pej xeem TV, video recorders, CD players, photocopiers, xov tooj, cua txias, automotive electronics Cheebtsam, game consoles, thiab lwm yam. Kev lag luam hauv tsev thiab txawv teb chaws muaj kev xav tau ntau ntxiv rau cov khoom siv hluav taws xob qib tooj liab, tshwj xeeb tshaj yog cov khoom siv hluav taws xob qib tooj liab. Cov koom haum tshaj lij tshaj lij kwv yees tias los ntawm 2015, Tuam Tshoj txoj kev xav tau hluav taws xob hauv qib tooj liab yuav ncav cuag 300,000 tons, thiab Tuam Tshoj yuav dhau los ua lub ntiaj teb loj tshaj plaws kev tsim khoom rau cov ntawv luam tawm Circuit Court boards thiab tooj liab foils. Kev ua lag luam rau hluav taws xob qib tooj liab ntawv ci, tshwj xeeb tshaj yog cov ntawv ci ua tau zoo, yog qhov zoo. .
3. lub ntiaj teb no muab tooj liab ntawv ci
Muaj cov ntawv ci tooj liab tuaj yeem muab faib ua ob pawg: dov tooj liab ntawv nyiaj (RA tooj liab ntawv ci) thiab cov ntsiab lus daws tooj liab (ED tooj liab ntawv ci). Ntawm lawv, dov tooj liab ntawv ci muaj qhov zoo ductility thiab lwm yam ntxwv, uas yog siv rau hauv cov txheej txheem muag muag thaum ntxov. Copper foil, thiab electrolytic copper foil muaj qhov zoo ntawm cov nqi tsim khoom qis dua li cov ntawv ci tooj liab. Txij li thaum dov tooj liab ntawv ci yog ib qho tseem ceeb raw khoom rau saj zawg zog boards, kev txhim kho cov yam ntxwv thiab cov nqi hloov ntawm dov tooj liab ntawv ci muaj ib tug tej yam cuam tshuam rau lub saj zawg zog board kev lag luam.
Txij li thaum muaj tsawg dua manufacturers ntawm dov tooj liab ntawv ci, thiab cov cuab yeej siv kuj yog nyob rau hauv ob txhais tes ntawm ib co manufacturers, cov neeg muas zaub muaj ib tug tsawg degree ntawm kev tswj ntawm cov nqi thiab cov khoom. Yog li ntawd, tsis muaj kev cuam tshuam rau cov khoom lag luam, electrolytic tooj liab ntawv ci yog siv los hloov cov ntawv ci tooj liab yog qhov ua tau. Txawm li cas los xij, yog tias cov khoom siv ntawm lub cev ntawm cov ntawv ci tooj liab nws tus kheej yuav cuam tshuam rau etching yam nyob rau hauv ob peb xyoos tom ntej no, qhov tseem ceeb ntawm dov tooj liab ntawv ci yuav nce ntxiv hauv cov khoom thinner lossis thinner dua, thiab cov khoom siv high-frequency vim kev sib txuas lus.
Muaj ob qho kev cuam tshuam loj rau kev tsim cov ntawv yob tooj liab, cov khoom siv thiab cov teeb meem kev lag luam. Cov kev pab cuam cuam tshuam yog hais txog qhov xav tau ntawm cov khoom siv tooj liab los txhawb kev tsim cov ntawv yob tooj liab, thiab nws tseem ceeb heev rau kev tuav cov peev txheej. Ntawm qhov tod tes, technical obstacles cuam tshuam ntau tus neeg tuaj tshiab. Ntxiv nrog rau kev siv tshuab calendering, kev kho deg lossis oxidation kho tshuab kuj tseem siv. Feem ntau cov tuam txhab lag luam thoob ntiaj teb muaj ntau yam cuab yeej technology patents thiab cov cuab yeej tseem ceeb Paub Yuav Ua Li Cas, uas ua rau muaj kev cuam tshuam rau kev nkag. Yog tias cov neeg nkag tshiab tom qab sau qoob loo thiab ntau lawm, lawv raug txwv los ntawm tus nqi ntawm cov tuam txhab loj, thiab nws tsis yooj yim rau kev koom nrog kev lag luam. Yog li ntawd, lub ntiaj teb no dov tooj liab ntawv ci tseem belongs rau lub lag luam nrog muaj zog exclusiveness.
3. txoj kev loj hlob ntawm cov ntawv ci tooj liab
Copper foil hauv lus Askiv yog electrodepositedcopperfoil, uas yog ib qho tseem ceeb rau kev tsim cov tooj liab clad laminate (CCL) thiab luam tawm Circuit Board (PCB). Nyob rau niaj hnub no txoj kev loj hlob sai ntawm cov ntaub ntawv xov xwm hauv kev lag luam, electrolytic copper foil hu ua: "neural network" ntawm cov khoom siv hluav taws xob hluav taws xob thiab hluav taws xob xa mus thiab kev sib txuas lus. Txij li xyoo 2002, cov nqi tsim khoom ntawm cov ntawv luam tawm hauv Suav teb tau dhau qhov chaw thib peb hauv ntiaj teb, thiab tooj liab clad laminates, cov khoom siv substrate ntawm PCBs, kuj tau dhau los ua tus tsim khoom loj thib peb hauv ntiaj teb. Yog li ntawd, Tuam Tshoj txoj kev lag luam electrolytic tooj liab ntawv ci tau tsim los ntawm leaps thiab ciam teb rau xyoo tas los no. Yuav kom nkag siab thiab nkag siab txog yav dhau los thiab tam sim no ntawm lub ntiaj teb thiab kev txhim kho ntawm Tuam Tshoj txoj kev lag luam electrolytic tooj liab ntawv ci, thiab tos ntsoov rau yav tom ntej, cov kws tshaj lij ntawm Tuam Tshoj Epoxy Resin Industry Association tau tshuaj xyuas nws txoj kev loj hlob.
Los ntawm qhov kev xav ntawm lub tuam tsev tsim khoom thiab kev lag luam kev lag luam ntawm electrolytic tooj liab ntawv ci kev lag luam, nws txoj kev loj hlob tuaj yeem muab faib ua peb lub sijhawm loj hlob: Tebchaws Asmeskas tau tsim thawj lub ntiaj teb tooj liab ntawv ci lag luam thiab lub sij hawm thaum electrolytic tooj liab ntawv ci kev lag luam pib; Nyiv tooj liab ntawv nyiaj Lub sij hawm thaum cov lag luam tag nrho monopolize lub ntiaj teb ua lag luam; lub sij hawm thaum lub ntiaj teb no multi-polarized los sib tw ua lag luam.
