PCByog cov khoom siv hluav taws xob uas nquag siv hauv cov khoom siv hluav taws xob, feem ntau yog siv los txuas cov khoom siv hluav taws xob thiab cov xov hlau. Hauv cov txheej txheem tsim PCB, kab dav yog qhov tseem ceeb heev uas cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ruaj ntseg ntawm lub rooj tsav xwm hauv Circuit Court.
Yog li, hauv PCB tsim, yuav tsum xaiv kab dav npaum li cas? Puas yog txoj kab dav dav yuav tsum zoo dua?
1, Dab tsi yog qhov tsawg kawg nkaus txoj kab dav?
Hauv kev tsim PCB, qhov tsawg kawg kab dav ncaj qha cuam tshuam rau lub peev xwm kis tau tus mob thiab distortion ntawm lub rooj tsav xwm Circuit Court. Qhov me me ntawm txoj kab dav, qhov ntau dua qhov tsis kam, uas tuaj yeem ua rau poob hauv cov teeb liab kis.
Feem ntau, cov specification rau PCB kab dav yog 10mm (0.254mm), uas yog tam sim no universal kab dav txais los ntawm feem ntau manufacturers thiab muaj peev xwm ua tau raws li feem ntau daim ntawv thov scenarios. Tab sis nyob rau hauv high-ceev teeb liab kis tau tus mob, txoj kab dav yuav tsum muaj ntau tshaj 10 mil.
Thaum lub thickness ntawm lub PCB board yog tsawg tshaj li 1. . Tib lub sijhawm, nws tuaj yeem txo cov teeb liab synchronization thiab poob teeb meem. Thaum lub PCB board yog tuab, qhov yuav tsum tau rau kab dav yog nruj dua.
Thaum txiav txim siab qhov tsawg kawg nkaus PCB kab dav, nws yog ib qho tsim nyog yuav tsum xav txog qhov tsis xws li Circuit Court zaus, kab ntev, thiab lub rooj tsav xwm thickness.
2, Puas yog txoj kab dav dav yuav tsum zoo dua?
Feem ntau hais lus, qhov dav ntawm txoj kab dav, qhov me me ntawm qhov tsis kam, uas txo qhov poob thaum lub teeb liab kis tau tus mob. Lub caij no, kev nthuav dav ntawm txoj kab dav yuav ua rau kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm lub voj voog.
Txawm li cas los xij, txoj kab dav dav kuj tuaj yeem qhia qee qhov teeb meem, xws li inductance. Cov teeb liab ceev dhau kuj tuaj yeem ua rau muaj teeb meem hluav taws xob xws li kev xav, kev sib txawv, thiab cov khoom sib txuas tam sim no hauv lub rooj tsavxwm vim muaj cov kab dav dav, uas tuaj yeem cuam tshuam cov teeb liab stability thiab cov ntaub ntawv xa mus ceev.
Ntxiv mus, PCB kab dav uas dav dhau tuaj yeem pov tseg qhov chaw thiab nce nqi ntau lawm.
Yog li ntawd, thaum xaiv PCB kab dav, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm kev sib raug zoo ntawm kev ruaj ntseg, chaw cia khoom, thiab tus nqi, thiab txhim kho cov kev daws teeb meem zoo. Lub caij no, txoj kab tsim nyog yuav tsum tau xaiv raws li qhov xav tau tiag tiag.
