Koj pom yim yim txheej txheej tsim hauv PCB

Nws yog ib qho tseem ceeb kom nkag siab thiab paub qhov txawv ntawm txheej txheej PCB. Kom nkag siab zoo dua qhov tuab ntawm PCB, yuav tsum muaj qhov sib txawv zoo kom ntseeg tau tias PCB ua haujlwm tau zoo tshaj plaws. Cov txheej hauv qab no feem ntau pom hauv pawg PCBS. Cov no tuaj yeem sib txawv, nyob ntawm seb muaj pes tsawg txheej, tus tsim qauv, thiab tus tsim nws tus kheej.

L txheej txheej tshuab

Nov yog txheej txheej yooj yim ntawm PCB. Nws yog siv raws li tus txheej txheem ntawm lub rooj tsav xwm hauv Circuit Court. Nov yog lub hauv paus txheej txheem ntawm PCB. Cov txheej no tseem ua rau tus tsim qauv sib tham txog qhov tseeb ntawm qhov av thiab qhov txiav.

L khaws txheej

Cov txheej no zoo ib yam li txheej txheej txheej hauv qhov uas nws tseem tuaj yeem siv ua lub ntsej muag. Txawm li cas los xij, txoj haujlwm ntawm txheej tuav yog txhawm rau txheeb xyuas thaj chaw rau tso cov khoom siv hluav taws xob, txuas xov hluav taws xob, thiab lwm yam. Tsis muaj cov khoom siv lossis cov khoom siv hluav taws xob tso rau sab nraud qhov ciam teb no. Cov txheej no txwv cov kab hluav taws xob ntawm CAD cov cuab yeej hla cov cheeb tsam tshwj xeeb.

L txheej txheej

Cov txheej txheem txheej txheem yog siv los txuas cov khoom siv. Cov khaubncaws sab nraud povtseg no tuaj yeem nyob ntawm ob sab ntawm lub rooj tsavxwm. Kev tso cov txheej txheem yog nyob ntawm tus tsim qauv, leej twg txiav txim siab raws li daim ntawv thov thiab cov khoom siv.

L Lub dav hlau av thiab lub dav hlau fais fab

Cov txheej no tseem ceeb heev rau kev ua haujlwm kom raug ntawm PCB. Cov av hauv av thiab kev faib cov av hauv thoob plaws lub rooj tsav xwm hauv Circuit Court thiab nws cov khoom siv. Lub hwj chim txheej, ntawm qhov tod tes, txuas nrog ib qho ntawm qhov hluav taws xob nyob ntawm PCB nws tus kheej. Ob txheej tuaj yeem tshwm rau saum, hauv qab, thiab tawg cov phaj ntawm PCB.

L Split dav hlau

Lub dav hlau sib cais yog lub hauv paus dav hlau sib cais. Piv txwv, lub dav hlau fais fab ntawm lub rooj tsavxwm tuaj yeem faib ua ob qho. Ib nrab ntawm lub dav hlau fais fab tuaj yeem txuas nrog + 4V thiab lwm qhov ib nrab rau -4V. Yog li, cov khoom siv ntawm lub rooj tsavxwm tuaj yeem ua haujlwm nrog ob qhov sib txawv sib txawv nyob ntawm lawv qhov kev sib txuas.

L Npog/txheej txheej

Cov silkscreen txheej tau siv los siv cov ntawv cim rau cov khoom siv tso rau saum lub rooj tsavxwm. Cov txheej txheem ua haujlwm zoo ib yam tshwj tsis yog rau hauv qab ntawm phaj. Cov txheej no pab hauv kev tsim khoom thiab debugging txheej txheem.

L tsis kam vuam txheej

Cov tooj liab tooj liab thiab hla-qhov ntawm cov laug cam yog qee zaum hu ua kev tiv thaiv npog ntawm txheej txheej tsis kam tiv thaiv. Cov txheej no khaws cov hmoov av, hmoov av, ya raws thiab lwm yam ib puag ncig kom deb ntawm lub rooj tsavxwm.

L txheej txheej tshuaj txhuam

Siv cov tshuaj txhuam tom qab sib dhos saum npoo av. Nws pab txhawm rau txuas cov khoom sib txuas rau lub rooj tsav xwm hauv Circuit Court. Nws tseem pab txhawb kev ntws dawb ntawm cov kab laug sab hauv PCB suav nrog cov khoom siv saum npoo.

Tag nrho cov txheej no yuav tsis muaj nyob hauv ib txheej PCB. Cov khaubncaws sab nraud povtseg no yog tsim los ntawm cov ntawv luam tawm Circuit board tsim. Cov txheej txheem tsim no pab kwv yees tag nrho cov tuab ntawm PCB thaum txhua qhov tuab tuab ntawm micron suav nrog. Cov ntsiab lus no yuav pab koj tswj hwm kev nruj nruj pom nyob hauv PCB feem ntau tsim.
