PCB Ntsug Ntsug Cov Khoom Siv Ntsug Ntsug tau dhau los ua cov kev daws rau cov engineers nrhiav kom yooj yim xaim thiab txhawb txoj kev ntseeg tau ntawm lawv cov cuab yeej. Cov terminals no tsim nrog ib tug hniav uas tso cov ciav hlau mus rau cov xov xwm hluav taws xob, ua kom yooj yim txuas thiab ruaj ntseg xov hlau. Tab sis koj yuav siv li cas kom raug? Cia peb rhuav nws qis kauj ruam los ntawm kauj ruam.
Thawj yam: Xaiv lub davhlau ya nyob twg. Koj yuav tsum tau xaiv cov qauv uas phim koj txoj haujlwm yuav tsum tau ua. Xav txog yam zoo ib yam li thauj khoom tam sim no, ntsuas hluav taws xob, thiab qhov loj ntawm cov xaim koj siv. Cov Khoom Taw Qhia Cov Khoom Uas Muaj Feem Ntau Lawm Xws Li Tooj Liab suav nrog tooj liab, thiab kub-plated tooj liab, txhua yam uas muaj kev ua haujlwm zoo thiab kev tawm tsam zoo thiab corrosion.
Thaum koj tau txais lub davhlau ya nyob twg, nws yog lub sijhawm los nruab nws. Pib los ntawm kev tso cov davhlau ya nyob twg mus rau hauv qhov chaw tsim lossis cov ntaub qhwv ncoo rau ntawm koj cov Circuit Court board. Nco ntsoov tias cov hniav tau zoo kawg nkaus rau cov thawj coj, tom qab ntawd solder nws hauv qhov chaw. Ua tib zoo saib nrog soldering hlau-dhau tshav kub tuaj yeem ua rau lub davhlau ya nyob twg los yog pawg thawj coj. Tom qab soldering, lob ib tug mult analimeter rau kev sim cov kev txuas thiab xyuas kom txhua yam ua haujlwm raws li nws yuav tsum tau.
Tam sim no, cia peb tham txog kev sib txuas cov hlau. Sawb lub rwb thaiv tsev los ntawm cov hlau kom ua rau tus neeg xyuas pib, ces xaub nws mus rau hauv lub davhlau ya nyob twg. Siv cov cuab yeej crimping lossis ntsia hlau kom ruaj ntseg sib txuas, ua kom nws nruj thiab txhim khu kev qha. Yog tias koj tab tom ua haujlwm ntawm ib qho haujlwm uas koj yuav tsum tau kaw xov hlau thiab rov hais dua cov xov hlau feem ntau, suav siv cov terminals ntau-lawv ua kev tu muag tshau.
Ob peb lub tswv yim kom nco ntsoov: ib txwm kos duab ob zaug uas koj lub davhlau ya nyob twg thiab hlau tau sib haum. Mismatched specs tuaj yeem ua rau overheating lossis txawm tias luv luv voj voog. Yog tias koj lub cuab yeej yuav muaj qhov kub lossis av noo, xaiv rau cov terminals ua los ntawm tshav kub-resistant thiab corrosion-resistant cov ntaub ntawv. Thiab tsis txhob hnov qab xyuas cov kev sib txuas tsis tu ncua, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv uas txav lossis co, kom tiv thaiv ib qho teeb meem los ntawm kev daws teeb meem dhau sijhawm.
Raws li cov khoom siv hluav taws xob txuas ntxiv mus rau qhov loj me thiab loj hlob hauv cov nyom, PCB cov ntsug ntsug sparinals yog nrhiav lawv txoj hauv kev ntau thiab ntau daim ntawv thov. Los ntawm txhua hnub hauv tsev neeg gadget mus rau cov tshuab ua haujlwm hnyav, thiab dav hlau, cov terminals no muaj txiaj ntsig rau lawv txoj kev yooj yim rau lawv thiab kev cia siab. Saib tom ntej, nce qib hauv cov ntaub ntawv thiab kev tsim cov kev paub cog lus tias yuav muaj cov lus cog tseg no zoo dua, qhib kev hloov tshiab hauv kev tsim kho hluav taws xob.
