PCB hais txog cov Circuit Board , thaum PCBA hais txog cov Circuit Board plug-in los ua ke, SMT txheej txheem. Ib tug yog ib tug tiav board thiab lwm yam yog ib tug liab qab board. PCB (Tau luam tawm Circuit Board ), Ua los ntawm epoxy iav resinmaterial, nws muab faib ua 4, 6 thiab 8 txheej raws li cov xov tooj ntawm cov teeb liab txheej.
Yog li ntawd, lub ntsiab lus ntawm PCBA yog dab tsi?
PCBA (Printed Circuit Board Assembly) yog lub rooj tsavxwm tau txais tom qab tag nrho cov luam ntawv solder paste rau ntawm PCB thiab tom qab ntawd mounting ntau yam xws li resistors, ICs (Integrated Circuits), capacitors thiab lwm yam khoom xws li transformers nyob ntawm daim ntawv thov thiab cov yam ntxwv xav tau ntawm lub rooj tsavxwm.
PCB tsim yog dab tsi? A luam tawm Circuit Board ( PCB ) mechanically txhawb nqa thiab hluav taws xob txuas hluav taws xob cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob, cov ntaub qhwv thiab lwm yam khoom siv los ntawm ib lossis ntau daim ntawv txheej ntawm tooj liab laminatedonto thiab / lossis nruab nrab ntawm cov ntawv txheej ntawm cov ntaub ntawv uas tsis yog-conductivesubstrate.
Hauv qhov no, PCB sib dhos txhais li cas?
Printed Circuit Board los ua ke yog qhov txheej txheem ntawm kev txuas cov khoom siv hluav taws xob nrog cov xov hlau ntawm printedcircuit lub rooj tsavxwm. Cov kab los yog cov kab hluav taws xob tau kos rau hauv cov ntawv laminated tooj liab ntawm PCBs yog siv nyob rau hauv anon-conductive substrate nyob rau hauv thiaj li yuav tsim lub kev sib dhos.
Qhov txawv ntawm PCB thiab motherboard yog dab tsi?
Lub rooj tsavxwm yog ua los ntawm cov khaubncaws sab nraud povtseg, feem ntau yog ob mus rau 10, uas cuam tshuam cov khoom ntawm txoj kev tooj liab. Lub ntsiab luam tawm Circuit Board ( PCB ) hauv a system yog hu ua "system board" lossis " niam ntawv , "thaum cov me me uas ntsaws rau hauv cov qhov hauv lub rooj tsavxwm loj yog hu ua "boards" lossis "phaib." Saib lub voj voog hloov tau.

Dab tsi yog qhov txawv ntawm qhov sib txawv hauv zos thiab thoob ntiaj teb hauv SQL Server?
Qhov sib txawv hauv zos tau tshaj tawm hauv ib qho kev ua haujlwm whereas Ntiaj teb hloov pauv tau tshaj tawm sab nraum lub luag haujlwm. Cov kev hloov hauv zos tau tsim thaum lub luag haujlwm tau pib ua tiav thiab ploj thaum lub luag haujlwm xaus, ntawm qhov tod tes, Ntiaj teb hloov pauv yog tsim raws li kev tua pib thiab ploj thaum qhov kev pab cuam xaus
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov txawv ntawm cov ntaub ntawv hom thiab qhov sib txawv?
Ib qho kev sib txawv yuav tsum muaj cov ntaub ntawv sib txuas nrog nws, piv txwv li nws tuaj yeem muaj cov ntaub ntawv xws li cov lej, lej lej, cov cim thiab lwm yam. Qhov sib txawv ntawm hom Integer khaws cov lej suav thiab tus cim typevariable khaws cov cim tus nqi. Thawj qhov sib txawv ntawm ntau hom ntaub ntawv yog lawv qhov loj me me
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
