Lub siab nyob rau hauv lub tshuab nqus tsev plating film forming chamber yog sib npaug los yog qis dua 10-2Pa

Lub siab nyob rau hauv lub tshuab nqus tsev plating film forming chamber yog sib npaug los yog qis dua 10-2Pa

Nyob rau hauv lub tshuab nqus tsev, kev sib tsoo ntawm atoms thiab molecules ntawm cov khoom evaporation thiab lwm yam molecules nyob rau hauv tus txheej txheem ntawm ya mus rau cov khoom yas yuav txo tau, thiab cov tshuaj tiv thaiv (xws li oxidation) ntawm lub active molecules nyob rau hauv cov roj thiab evaporation qhov chaw. cov khoom yuav raug txo. Ceev, purity, deposition tus nqi thiab adhesion. Lub tshuab nqus tsev electroplating feem ntau xav kom lub siab nyob rau hauv zaj duab xis tsim chamber kom sib npaug los yog qis dua {{0}}Pa. Rau lub sijhawm uas qhov zoo ntawm evaporation qhov chaw, cov khoom yuav tsum tau plated thiab cov yeeb yaj kiab zoo siab, qhov siab yuav tsum qis dua (10-5Pa). Txheej thickness ntawm 0.04-0.1um, nyias nyias, tsis tshua muaj reflectivity; tuab heev, tsis zoo adhesion, yooj yim rau poob. Lub reflectivity yog 90 feem pua ​​thaum lub thickness yog 0.04.

Nqus electroplating electroplating khib nyiab

Qhov sib xyaw ntawm electroplating dej khib nyiab yog qhov nyuaj heev. Tsuas yog cyanide (CN-) cov dej khib nyiab thiab cov kua qaub-puag pov tseg, cov dej khib nyiab hnyav hlau yog ib pawg uas muaj feem cuam tshuam rau cov dej khib nyiab hauv kev lag luam electroplating. Raws li kev faib tawm ntawm cov hlau hnyav uas muaj nyob hauv cov dej khib nyiab hnyav, feem ntau tuaj yeem muab faib ua chromium (Cr) cov dej khib nyiab, nickel (Ni) cov dej khib nyiab, cadmium (Cd) cov dej khib nyiab, tooj liab (Cu) cov dej khib nyiab, zinc (Zn) cov dej khib nyiab, Kub (Au) dej khib nyiab, nyiaj (Ag) dej khib nyiab, thiab lwm yam.

Kev kho cov dej khib nyiab electroplating tau txais kev saib xyuas thoob plaws hauv tsev thiab txawv teb chaws, thiab ntau yam kev kho cov thev naus laus zis tau tsim los tshem tawm thiab txo cov paug tawm ntawm cov hlau hnyav los ntawm kev ntsuas xws li hloov cov tshuaj lom mus rau qhov tsis muaj tshuaj lom, hloov cov teeb meem tsis zoo, rov ua dua tshiab. hlau, thiab rov ua dej. Nrog rau txoj kev loj hlob sai ntawm kev lag luam electroplating thiab kev tiv thaiv ib puag ncig, tam sim no, kev kho cov dej khib nyiab electroplating tau pib nkag mus rau theem ntawm cov txheej txheem huv huv, tag nrho kev tswj hwm thiab kev lag luam kev sib koom ua ke. Kev siv cov khoom siv rov ua dua tshiab thiab kaw-circuit ncig yog cov lus qhia tseem ceeb ntawm kev txhim kho.
