2. PVD Txheej
Lub cev Vapor Deposition (PVD) thev naus laus zis yog siv los tso cov yeeb yaj kiab tooj liab nyias ntawm cov khoom siv hluav taws xob. Cov kauj ruam no txhim kho cov hluav taws xob thiab thermal conductivity ntawm lub substrate thaum txhim kho nto adhesion, kom ntseeg tau qhov zoo ntawm cov electroplated tooj liab txheej tom ntej.
3. Electroplating Thickening
Lub tsev ntawm PVD txheej, electroplating yog siv los ua kom tuab txheej tooj liab. Cov kauj ruam no ntxiv dag zog rau cov kav ntev thiab kev ua haujlwm ntawm cov txheej tooj liab kom tau raws li qhov xav tau ntawm kev siv hluav taws xob siab. Lub thickness ntawm cov txheej tooj liab tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb.
4. Circuit Court Patterning
Cov txheej txheem photolithography thiab tshuaj etching yog siv los tsim cov qauv kev sib tw ntawm cov txheej tooj liab. Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom cov hluav taws xob conductivity thiab stability ntawm lub circuit.
5. Solder Mask thiab Marking
Ib txheej ntawm daim npog ntsej muag yog siv los tiv thaiv qhov chaw tsis muaj hluav taws xob ntawm lub voj voog. Cov txheej no tiv thaiv luv luv Circuit Court thiab txhim kho cov khoom rwb thaiv tsev ntawm cov substrate.
6. Kev kho deg
Kev ntxuav saum npoo, polishing, los yog txheej txheej yog ua los xyuas kom meej qhov chaw du thiab tshem tawm cov kab mob uas tuaj yeem cuam tshuam kev ua haujlwm. Kev kho deg kuj txhim kho corrosion kuj ntawm substrate.
7. Laser Shaping
Thaum kawg, kev ua laser yog siv rau kev ua kom tiav, kom ntseeg tau tias lub substrate ua tau raws li cov qauv tsim tshwj xeeb ntawm cov duab thiab qhov loj me. Cov kauj ruam no muab high-precision machining, tshwj xeeb tshaj yog rau complex-shaped Cheebtsam siv nyob rau hauv hluav taws xob thiab sab hauv daim ntaub ntawv.
