Nrog rau siab thov nyob rau hauv ib tug ntau yam ntawm industrial cov khoom, tooj liab yog saib raws li ib tug ntau yam khoom siv.
Copper foils yog tsim los ntawm cov txheej txheem tsim tshwj xeeb hauv cov ntawv ci uas suav nrog ob qho tib si kub thiab txias dov.
Nrog rau txhuas, tooj liab yog siv dav hauv cov khoom lag luam ua cov khoom siv ntau yam ntawm cov ntaub ntawv tsis yog hlau. Tshwj xeeb tshaj yog nyob rau xyoo tas los no, qhov kev thov rau cov ntawv ci tooj liab tau nce ntxiv rau cov khoom siv hluav taws xob suav nrog cov xov tooj ntawm tes, cov koob yees duab digital, thiab IT khoom siv.
Foil fabrication
Nyias tooj liab foils yog tsim los ntawm electrodeposition los yog dov. Rau electrodeposition qib siab tooj liab yuav tsum tau yaj nyob rau hauv ib tug acid los tsim ib tug tooj liab electrolyte. Cov tshuaj electrolyte no yog pumped rau hauv ib nrab rau hauv, rotating nruas uas yog hluav taws xob. Ntawm cov nruas no nyias zaj duab xis ntawm tooj liab yog electrodeposited. Cov txheej txheem no tseem hu ua plating.
Nyob rau hauv cov txheej txheem electrodeposited tooj liab, tooj liab ntawv yog tso rau ntawm ib tug titanium rotating nruas los ntawm ib tug tooj liab tov qhov twg nws yog txuas mus rau ib tug DC voltage qhov chaw. Lub cathode txuas nrog lub nruas thiab cov anode yog submerged hauv cov tshuaj tooj liab electrolyte. Thaum siv hluav taws xob, tooj liab tso rau ntawm lub nruas thaum nws tig ntawm qhov nrawm heev. Cov tooj liab nto ntawm lub nruas sab yog du thaum sab nraud yog ntxhib. Qhov qeeb qeeb ntawm lub nruas nrawm, qhov tuab ntawm tooj liab tau txais thiab vice versa. Cov tooj liab yog attracted thiab sau rau ntawm cathode nto ntawm titanium nruas. Lub matte thiab nruas sab ntawm cov ntawv ci tooj liab mus txog kev kho mob sib txawv kom cov tooj liab tuaj yeem tsim nyog rau PCB fabrication. Cov kev kho mob txhim kho adhesion ntawm tooj liab thiab dielectric interlayer thaum lub sij hawm tooj liab clad lamination txheej txheem. Lwm qhov zoo ntawm cov kev kho mob yog los ua cov tshuaj tiv thaiv tarnish los ntawm kev qeeb oxidation ntawm tooj liab.
Daim duab 1:Electrodeposited Copper Manufacturing Process Daim duab 2 qhia txog kev tsim cov txheej txheem ntawm cov khoom siv tooj liab. Cov khoom siv dov yog kwv yees faib ua peb hom; uas yog, kub dov mills, txias dov mills, thiab ntawv ci mills.
Cov coils ntawm nyias foils yog tsim thiab tau txais kev kho tshuaj thiab kho tshuab tom qab kom txog thaum lawv tsim los rau hauv lawv cov duab kawg. Daim duab schematic ntawm cov txheej txheem dov ntawm tooj liab foils yog muab nyob rau hauv daim duab 2. Ib qho thaiv ntawm cov tooj liab casted (kwv yees qhov ntev: 5mx1mx130mm) yog rhuab mus txog 750 ° C. Tom qab ntawd, nws yog kub dov reversibly nyob rau hauv ob peb kauj ruam mus rau 1/10 ntawm nws thawj thickness. Ua ntej thawj qhov txias dov cov nplais uas tshwm sim los ntawm kev kho cua sov raug tshem tawm los ntawm milling. Nyob rau hauv cov txheej txheem txias dov lub thickness yog txo kom txog li 4 hli thiab cov nplooj ntawv yog tsim rau coils. Cov txheej txheem yog tswj nyob rau hauv xws li ib txoj kev uas cov khoom tsuas tau ntev thiab tsis hloov nws dav. Raws li cov nplooj ntawv tsis tuaj yeem tsim ib qho ntxiv hauv lub xeev no (cov khoom siv tau ua haujlwm hnyav heev) lawv tau txais kev kho cua sov thiab ua kom sov txog li 550 ° C.
