PCB thiab PCBA txhais li cas?

PCB thiab PCBA txhais li cas? Dab tsi yog qhov txawv ntawm PCB thiab PCBA?

Cov neeg feem coob paub txog cov ntsiab lus Circuit Board, PCB board, thiab PCB. Qhov tseeb, peb lo lus no hais txog tib yam. Txawm li cas los xij, feem ntau cov neeg uas tsis nyob hauv kev lag luam hluav taws xob yuav yog me ntsis tsis paub txog lub sij hawm PCBA. Nws kuj tseem yuav tsis meej pem nrog PCB. Txawm hais tias tsuas muaj ib lo lus sib txawv ntawm PCB thiab PCBA, muaj qhov sib txawv loj ntawm lawv hauv kev tsim khoom siv hluav taws xob.

PCB yog dab tsi?

Lub npe tag nrho ntawm PCB yog Printed Circuit Board, hu ua "circuit board". Kev tsim cov ntawv luam tawm Circuit Court boards yog tiag tiag cov tshuab luam ntawv uas ua raws li phau ntawv. Txawm li cas los xij, nrog kev nce qib ntawm cov thev naus laus zis, kev tsim cov ntawv luam tawm Circuit Board tau dhau los ua ntau thiab ntau dua.

Hom PCB no uas tau luam tawm cov hluav taws xob hauv hluav taws xob tab sis tseem tsis tau sib sau cov khoom siv hluav taws xob feem ntau hu ua lub rooj tsav tsheb liab qab.

PCB boards tuaj yeem siv rau hauv ntau hom kev siv, thiab lawv qhov tshwj xeeb tuaj yeem raug sau tseg raws li hauv qab no:

1. Cov kab hluav taws xob siab, qhov me me, thiab lub teeb yuag yog qhov zoo rau cov khoom siv hluav taws xob me me. 2. tuaj yeem tsim tau. PCB thiab PCBA tam sim no tuaj yeem tsim tau yuav luag tag nrho, uas txo cov nqi zog thiab txhim kho kev tsim khoom, uas muaj txiaj ntsig zoo los txo cov nqi khoom lag luam thiab kev ua lag luam nrov.

3. Cov qauv tsim tuaj yeem ua qauv lossis tsim raws li cov qauv. Thaum xav tau cov haujlwm sib txawv, tsuas yog hloov tag nrho PCBA pawg thawj coj saib.

PCBA yog dab tsi?

PCBA (Printed Circuit Board Assembly) yog cov txheej txheem ntawm kev sib sau ua ke ntau yam khoom siv hluav taws xob rau hauv lub rooj tsav xwm luam tawm (PCB) los tsim cov khoom siv hluav taws xob ua haujlwm. PCBA yog ib kauj ruam tseem ceeb hauv kev tsim cov khoom siv hluav taws xob, vim nws koom nrog kev sib txuas ntawm ntau qhov chaw los tsim cov khoom ua haujlwm tag nrho.

PCB ua lub hauv paus rau cov khoom siv hluav taws xob thiab muab cov hluav taws xob sib txuas ntawm cov khoom siv. Cov khoom siv hluav taws xob, xws li cov resistors, capacitors, thiab kev sib xyaw ua ke, tau teeb tsa rau hauv PCB siv Surface Mount Technology (SMT) thiab Dual In-line Package (DIP), SMT thiab DIP yog ob qho tib si hluav taws xob ntim tshuab siv los txuas cov khoom siv hluav taws xob rau circuit boards.

PCBA suav nrog ntau theem, suav nrog kev tsim, kev tsim, kev tso kawm, kev sib txuas, thiab kev sim. Cov txheej txheem yog nqa tawm nrog kev tswj xyuas nruj kom ntseeg tau tias muaj kev ua haujlwm siab thiab txhim khu kev qha kawg khoom.
