Nrog kev thov kom siab dua nyob rau hauv ntau cov khoom lag luam muaj, tooj liab yog saib raws li ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau ntau yam.
Tooj liab ntawv ci yog tsim los ntawm cov txheej txheem tsim kev tsim khoom tshwj xeeb hauv ntawv ci zeb uas suav nrog ob qho kub thiab txias dov.
Nrog rau txhuas, tooj liab tau siv cov khoom lag luam muaj cov khoom siv uas tsis muaj cov ntaub ntawv hlau uas tsis muaj hlau. Tshwj xeeb nyob rau hauv xyoo tsis ntev los no, qhov kev thov rau tooj liab ntawv ci tau nce rau cov khoom siv hluav taws xob suav nrog cov xov tooj txawb, digital cov koob yees duab, thiab nws cov khoom siv.

Nyias tooj liab ntawv ci yog tog los ntawm hluav taws xob lossis dov. Rau Electrodeposition High tooj tus tooj yuav tsum tau yaj nyob rau hauv ib lub acid los ua cov tooj liab electrolyte. Cov tshuaj electrolyte no yog muab tso rau hauv qee cov tshuaj uas siv tau, cov nruas sib hloov uas yog siv hluav taws xob. Ntawm cov tub yees no ib cov yeeb yaj kiab nyias ntawm tooj liab yog entrepodeposited. Tus txheej txheem no tseem hu ua plating.
Nyob rau hauv ib qho kev siv hluav taws xob tsim qauv, cov ntawv ci yog muab tso rau ntawm lub cav titanium uas nws txuas nrog DC Voltage. Tus Cathoo txuas nrog lub nruas thiab anode yog submerged nyob rau hauv cov tooj liab electrolyte tov. Thaum lub teb hluav taws xob tau siv, tooj liab tau tso rau ntawm lub nruas thaum nws tig hauv ib qho qeeb heev. Tus tooj liab saum npoo ntawm lub nruas sab yog du thaum lub sab tsis sib xws yog ntxhib. Lub qeeb qeeb lub nruas ceev, lub thicker tus tooj tooj tau txais thiab rov ua dua. Tus tooj liab tau nyiam thiab sau rau ntawm cov Cathode nto ntawm titanium nruas. Lub matte thiab nruas sab ntawm cov ntawv xov tooj liab mus los ntawm kev kho mob sib txawv kom tus tooj liab tuaj yeem tsim nyog rau PCB fabrication. Cov kev kho mob txhim kho adhesion nruab nrab ntawm tooj liab thiab dielectric interlayer thaum tooj liab clad lamination txheej txheem. Lwm qhov zoo dua ntawm kev kho mob yog ua kom cov neeg sawv cev los tiv thaiv kev tiv thaiv los ntawm kev qeeb qeeb oxidation tooj liab.
Daim duab 1:Electrodeposited Tooj Liab Manufacturation 2 piv txwv txog cov txheej txheem ntawm cov khoom tooj liab. Cov khoom siv dov yog kwv yees muab faib ua peb yam; namely, kub dov mills, dov lub cleam cold, thiab ntawv ci mills.
Coils ntawm cov ntawv puab nyias yog tsim thiab yauv ua tshuaj thiab kev kho mob kho tshuab kom txog thaum lawv tsim rau hauv lawv cov duab kawg. Ib txheej txheem schematic of Rolling cov txheej txheem ntawm tooj liab foils (kwv yees qhov ntev: 5mx130mm) yog rhuab txog 750 ° C. Tom qab ntawd, nws yog kub dov tawm hauv ob peb kauj ruam nqes mus rau 1/10 ntawm nws daim qauv tuab. Ua ntej thawj txias dov cov nplai uas los ntawm kev kho cua sov raug tshem tawm los ntawm milling. Nyob rau hauv cov txheej txheem txias txias lub thickness yog txo kom txog 4 mm thiab cov ntawv txheeb yog tsim rau coils. Cov txheej txheem yog tswj tau nyob rau hauv xws li txoj kev uas cov ntaub ntawv tsuas tau txais ntev dua thiab tsis hloov nws qhov dav. Raws li cov ntawv txheeb tsis tuaj yeem tsim ib qho ntxiv hauv lub xeev no (cov khoom siv tau ua haujlwm hardened ntau ntxiv) lawv tau kev kho cua sov thiab yog rhaub kom txog 550 ° C.
