Ua Kev Txiav Txim Siab Cheebtsam Kev sim
Kev ntsuam xyuas txhua tus neeg tiv thaiv feem ntau yog cov txheej txheem zoo tshaj plaws rau Kev daws teeb meem PCB . Kev ntsuas txhua qhov resistor, capacitor, diode, transistor, inductor, MOSFET, LED, thiab discrete active cov khoom tuaj yeem ua nrog multimeter lossis LCR meter.
Tib neeg kuj nug, koj yuav ua li cas kho lub rooj tsavxwm?
Cov kauj ruam los txhim kho thiab daws teeb meem PCBs
- Kauj Ruam #1. Ntxuav lub PCB.
- Kauj Ruam #2. Tshem tawm lub Pad puas.
- Kauj Ruam #3. Clear Away Laminate Nyob ib ncig ntawm lub ncoo.
- Kauj Ruam #4. Tshem Tawm Cov Qub Solder Mask.
- Kauj Ruam #5. Ntxuav Nrog Cawv.
- Kauj Ruam #6. Npaj tus neeg xyuas pib.
- Kauj Ruam #7. Tshawb xyuas thiab xaiv qhov tsim nyog Circuit Court ncej.
- Kauj Ruam #8.
Ib tug kuj yuav nug, koj tuaj yeem qhia tau li cas yog tias lub rooj tsav xwm Circuit Court tsis zoo? Tshawb xyuas cov Circuit Board ze rau qhia - lus kos npe ntawm cov khoom tsis ua haujlwm. Cov khoom yuav tau hlawv thiab ua kom tsis muaj xim lossis hlawv lub rooj tsavxwm hauv qab. Nrhiav cov o los yog tawg. Tig lub lub rooj tsavxwm hla thiab ua tib zoo xyuas cov kab rau khawb thiab lwm yam kev puas tsuaj.
Qhov thib ob, koj ua li cas kuaj cov khoom siv hluav taws xob hauv Circuit Court?
Txuas thiab qhib lub zog rau koj Circuit Board dua thiab ntsuas qhov voltages ntawm cov inputs thiab outputs ntawm txhua tus cov khoom ntawm lub rooj tsavxwm . Siv koj lub voltmeter (saib Cov Lus Qhia) rau kuaj voltage theem ntawm tag nrho cov cov khoom 'input thiab output pins.
Yuav ua li cas koj kuaj Circuit Court boards?
Tshawb xyuas muab khoom rau lub Circuit Court : Thawj kauj ruam hauv kev tshuaj xyuas tus Circuit Court yog los xyuas kom meej tias nws muaj hwj chim muab rau nws. Qhov no yooj yim ua tiav siv lub multimeter teem rau qhov voltage ntau. Ntsuas qhov voltage siv lub multimter ntawm cov ntsiab lus uas cov khoom nkag mus rau hauv Circuit Board.

Cov teeb meem dab tsi yog tus qauv qauv daws teeb meem?
Cov qauv zoo yog siv los daws cov teeb meem uas tej zaum yuav (los yog pom tias lawv yuav) raug coj los siv lossis daws los ntawm cov tswv yim sib txawv thiab uas muaj cov lus qhia meej meej rau cov xwm txheej zoo li no
Muaj pes tsawg txoj kev daws teeb meem tuaj yeem muaj teeb meem LP?
"Tsis yog, nws tsis tuaj yeem ua rau tus qauv LP kom muaj ob qho kev daws teeb meem zoo." Tus qauv LP tuaj yeem muaj 1 qhov kev daws teeb meem zoo tshaj plaws lossis ntau dua 1 qhov kev daws teeb meem zoo, tab sis nws tsis tuaj yeem muaj 2 qhov kev daws teeb meem zoo
Kuv yuav daws teeb meem OneDrive sync teeb meem li cas?
Txhim kho OneDrive sync teeb meem Xyuas kom OneDrive khiav. Manually launchOneDrive los ntawm kev mus rau Start, ntaus onedrive hauv cov thawv ntawv no, tom qab ntawd xaiv OneDrive (Desktop app) los ntawm cov npe ntawm cov txiaj ntsig. Nco ntsoov tias koj cov ntaub ntawv qis dua OneDrive cov ntaub ntawv loj txwv ntawm 15 GB. Nco ntsoov tias koj muaj qhov hloov tshiab Windows tshiab thiab qhov tseeb version ntawm OneDrive
Dab tsi yog peb qhov tseem ceeb ntawm cov ntaub ntawv los daws cov teeb meem tshawb fawb txog kev lag luam?
Peb qhov chaw ntawm kev paub txog kev lag luam yog cov ntaub ntawv sab hauv, cov ntaub ntawv tseem ceeb, thiab cov ntaub ntawv thib ob. Cov ntaub ntawv sab hauv yog qhov zoo tshaj plaws rau kev saib xyuas kev muag khoom, sib qhia, thiab cov hom phiaj ntawm kev lag luam
Dab tsi yog qhov xav tau rau cov chav kawm paub daws teeb meem thiab kev paub daws teeb meem?
Cov chav kawm Abstract. Abstract (uas Java txhawb nrog cov ntsiab lus paub daws teeb meem) txhais tau hais tias chav kawm lossis txoj hauv kev lossis teb lossis txhua yam tsis tuaj yeem ua tam sim (uas yog, tsim) qhov twg nws tau txhais. Lwm yam khoom yuav tsum instantiate cov khoom nyob rau hauv nqe lus nug. Yog tias koj ua ib chav kawm abstract, koj tsis tuaj yeem instantiate ib yam khoom los ntawm nws
