Nyob rau ntawm theem sib txawv, tus qauv tsim yuav tsum teeb tsa ntawm cov ntsiab lus sib txawv. Hauv qhov tsim theem, qhov loj lattice qhov chaw yuav siv tau rau kev teeb tsa ntaus ntawv.
Rau cov cuab yeej loj xws li IC thiab cov neeg uas tsis yog nyob, qhov tsim ntawm qhov latent point precision ntawm 50 ~ 100mil yuav raug xaiv, thiab cov phiaj xwm ntawm 25mil tuaj yeem siv rau kev faib rau cov khoom siv me me xws li kev ua haujlwm tsis txaus ntseeg thiab kev ua haujlwm. Lub precision loj lattice cov ntsiab lus yog conducive rau cov kev sib tw ntawm cov khoom siv thiab qhov zoo nkauj ntawm kev teeb tsa.
Kev cai PCB kev cai:
1, tsis zoo li qub, tag nrho cov khoom yuav tsum muab dai rau ntawm cov laug cam ntawm tib qho, tsuas yog lub siab tshaj plaws lub caij sib ze, kom tau txais qee yam tsawg thiab cov khoom siv me me, xws li SMD resistor, SMD capacitors, SMD IC qis dua.
2. Raws li qhov tsim nyog ua kom muaj hluav taws xob, cov khoom yuav tsum muab tso rau ntawm kab sib chaws thiab teem caij sib luag lossis vertically, kom zoo nkauj thiab zoo nkauj. Feem ntau, cov cheebtsam yuav tsis pub kom sib npaug; Lub Cheebtsam yuav tsum tau compact, thiab lub Cheebtsam yuav tsum sib npaug sib npaug thoob plaws hauv qhov layout.
3. Qhov tsawg kawg ntawm qhov sib txawv ntawm cov khoom sib txawv ntawm lub Rooj Tswjhwm Saib Xyuas Circuit Court yuav tsum yog tshaj 1MM.
4, deb ntawm lub rooj tsav xwm ntug dej feem ntau tsis tsawg tshaj 2 hli. Qhov zoo tshaj plaws duab rau Circuit Court Board daim duab, qhov ntev-dav ntawm 3: 2 los yog 4: 3. Circuit Court board face 'yog siab tshaj 200 hli los ntawm 150 mm, yuav tsum tau saib xyuas lub rooj tsav xwm saibxyuas thiaj tuaj yeem ua tau txhua yam.
Hauv kev tsim qauv ntawm PCB, lub tsev ntawm pawg thawj coj saib xyuas yuav tsum tau txheeb xyuas, thiab qhov tsim qauv tsim yuav tsum tau ua tiav raws li qhov kev ua, thiab qhov teeb tsa ntawm txhua feem ntawm Circuit Court yuav tsum ua raws li cov hauv qab no:
1. Npaj lub chaw nyob ntawm txhua qhov kev ua haujlwm hauv lub nruab nrab raws li txoj cai Circuit txoj kev, kom qhov teeb tsa yooj yim rau cov teeb liab khiav thiab khaws cov teeb liab raws li qhov zoo tau.
2. Nrhav nyob ib ncig ntawm txhua yaam tseem ceeb ntawm txhua lub pliag, hab ua qhov teeb tsa puag ncig nwg. Cov cheebtsam yuav tsum sib npaug, sib npaug thiab kev cog lus ntawm PCB, txo thiab txo qhov ua thiab kev sib txuas ntawm cov khoom.
