Txawm tias nws yog lub teeb liab hloov pauv sai lossis lub teeb liab tsis muaj zog, nws tuaj yeem hloov pauv mus rau hauv lub teeb liab digital, muab cov ntaub ntawv tseeb rau kev ua cov ntaub ntawv tom ntej thiab kev tshuaj xyuas, thiab ua tau raws li qhov yuav tsum tau ua ntawm kev tau txais cov ntaub ntawv ceev ceev.
Kev Ruaj Ntseg Zoo Tshaj Plaws thiab Kev Ntseeg Tau: Kev Xyuas Kom Tau Txais Cov Ntaub Ntawv Tsis Tu Ncua thiab Ruaj Khov
Cov khoom siv hluav taws xob zoo raug xaiv ua tib zoo, xws li cov capacitors ceramic ntau txheej nrog ESR qis ua ke nrog cov capacitors tantalum muaj peev xwm siab, kom ntseeg tau tias muaj lub zog hluav taws xob ntshiab thiab ruaj khov thiab txo cov kev cuam tshuam ripple. Cov inductors ferrite permeability siab thiab cov inductors hlau xaim siab raug tswj hwm kev cuam tshuam electromagnetic thiab txhim kho lub peev xwm tiv thaiv kev cuam tshuam ntawm lub voj voog. Tib lub sijhawm, los ntawm kev tshuaj xyuas zoo nruj, suav nrog kev tshuaj xyuas AOI thiab X-ray siab heev, nrog rau kev kuaj xyuas kev ua haujlwm thiab kev laus uas ua piv txwv rau cov xwm txheej siv tiag tiag, PCBA tuaj yeem ua haujlwm ruaj khov thiab ntseeg tau hauv cov chaw nyuaj thiab thaum lub sijhawm ua haujlwm ntev, ua rau lub sijhawm ua haujlwm tsis muaj qhov txhaum ntawm lub kaw lus tau txais cov ntaub ntawv ntev dua.
Kev Hloov Kho Ib Puag Ncig Zoo Kawg Nkaus: Kev daws teeb meem nrog cov chaw ua haujlwm nyuaj nrog kev yooj yim
Qhov nyuaj ntawm qhov chaw khaws cov ntaub ntawv raug txiav txim siab tag nrho hauv kev tsim qauv. Cov khoom xaiv tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias ntawm - 40 ° C txog 85 ° C thiab qhov chaw noo noo ntawm 5% - 95% (tsis condensing). Tag nrho cov module muaj kev tsim tshwj xeeb tiv thaiv dej noo, tiv thaiv plua plav, thiab kev co, uas tuaj yeem tiv taus kev cuam tshuam ntawm plua plav, noo noo, thiab kev co hauv qhov chaw ua lag luam, thiab ib txwm muab kev ua haujlwm ruaj khov rau lub kaw lus khaws cov ntaub ntawv, hloov kho rau ntau qhov chaw ua haujlwm hnyav.
Kev Tsim Khoom Siv Hluav Taws Xob Zoo thiab Txuag Hluav Taws Xob: Ua Tus Thawj Coj ntawm Kev Txuag Hluav Taws Xob Tshiab hauv Kev Tau Txais Cov Ntaub Ntawv
Cov ADCs ua haujlwm siab thiab lwm yam khoom siv cov txheej txheem tsim khoom siab heev thiab muaj cov yam ntxwv siv hluav taws xob tsawg. Ua ke nrog kev tsim hluav taws xob tsim nyog thiab kev xaiv cov khoom, PCBA tuaj yeem hloov kho qhov kev siv hluav taws xob hauv ntau hom kev ua haujlwm sib txawv. Thaum ua tau raws li qhov yuav tsum tau ua ntawm kev tau txais cov ntaub ntawv ceev ceev, nws txo nws cov kev siv hluav taws xob ntau tshaj plaws, txhim kho kev siv hluav taws xob zoo, txuag cov nqi ua haujlwm ntev rau cov neeg siv, thiab ua raws li qhov sib txawv ntawm kev txuag hluav taws xob ntsuab.
Kev Pabcuam Kho Kom Haum: Tsim Cov Kev daws teeb meem tshwj xeeb rau kev nrhiav cov ntaub ntawv
