PCB (luam tawm Circuit Board)

PCB (luam tawm Circuit Board)

Nqe lus piav qhia luv:

PCB (luam tawm Circuit board) yog daim ntawv luam tawm Circuit board, sau luv li luam tawm Circuit board, uas yog ib qho tseem ceeb ntawm kev lag luam hluav taws xob. Yuav luag txhua yam khoom siv hluav taws xob, los ntawm lub tshuab hluav taws xob saib, lub laij lej, mus rau khoos phis tawj, khoom siv sib txuas lus hluav taws xob, cov cuab yeej siv tub rog, tsuav yog muaj cov khoom siv hluav taws xob xws li kev sib txuas ua ke, txhawm rau ua kom muaj hluav taws xob sib txuas ntawm ntau yam khoom siv yuav tsum luam tawm. pawg thawj coj saib.

Taw qhia PCB

Lub rooj tsav xwm luam tawm tau tsim los ntawm cov phaj insulating hauv qab, txuas cov hlau thiab cov ntaub qhwv rau sib sau ua ke thiab txuas cov khoom siv hluav taws xob, thiab muaj ob lub luag haujlwm ntawm kev siv hluav taws xob ua hluav taws xob thiab insulating phaj hauv qab. Nws tuaj yeem hloov txoj kab hluav taws xob nyuaj thiab paub txog kev txuas hluav taws xob ntawm ntau yam khoom siv hauv Circuit Court. Nws tsis tsuas yog ua kom yooj yim rau kev sib dhos thiab vuam cov khoom siv hluav taws xob, txo kev ua haujlwm ntawm cov xov hlau hauv txoj kev ib txwm muaj, thiab txo qis kev siv zog ntawm cov neeg ua haujlwm; nws kuj tseem txo tag nrho lub tshuab ntim khoom, txo tus nqi khoom, thiab txhim kho qhov zoo thiab ntseeg tau ntawm cov khoom siv hluav taws xob. Cov ntawv luam tawm Circuit Board muaj cov khoom lag luam zoo ib yam, thiab nws tuaj yeem siv tus qauv tsim, uas yog qhov muaj txiaj ntsig zoo rau kev ua tiav ntawm kev siv tshuab thiab kev siv tshuab hauv cov txheej txheem tsim khoom. Nyob rau tib lub sijhawm, tag nrho cov ntawv luam tawm Circuit board uas tau sib sau ua ke thiab debugged tuaj yeem siv ua qhov khoom seem ywj pheej los pab txhawb kev sib pauv thiab saib xyuas tag nrho cov khoom. Tam sim no, cov ntawv luam tawm Circuit Circuit tau siv dav hauv kev tsim cov khoom siv hluav taws xob.

Cov ntawv xov xwm hluav taws xob luam tawm ntxov tshaj plaws tau siv daim ntawv-raws tooj liab-npog cov laug cam. Txij li qhov tshwm sim ntawm cov khoom siv hluav taws xob hluav taws xob hauv xyoo 1950, qhov kev thov rau cov ntawv luam tawm tau nce siab. Tshwj xeeb, kev txhim kho sai thiab siv dav ntawm cov khoom siv hluav taws xob tau ua rau cov khoom siv hluav taws xob me dua thiab me dua, thiab qhov ntom ntom thiab qhov nyuaj ntawm cov xov hluav taws xob tau dhau los ua ntau dua thiab ntau dua, uas yuav tsum tau hloov kho tas li ntawm cov laug cam. Tam sim no, ntau yam ntawm cov laug cam uas tau luam tawm tau tsim los ntawm cov laug cam ib sab mus rau ob tog ob tog, cov laug cam ntau txheej thiab cov laug cam hloov pauv tau; cov qauv thiab kev ua tau zoo kuj tau tsim los rau qhov ntom ntom ntom ntom ntom ntom ntom ntom, ua kom me me thiab muaj kev ntseeg siab; cov txheej txheem tsim qauv tshiab, tsim khoom siv thiab cov khoom siv los ua Pawg Thawj Coj thiab cov txheej txheem tsim qauv txuas ntxiv mus. Nyob rau xyoo tsis ntev los no, ntau yam khoos phis tawj pab tsim qauv (CAD) luam tawm daim ntawv thov kev lag luam software tau nrov thiab txhawb nqa hauv kev lag luam. Ntawm cov tuam txhab tshwj xeeb luam tawm cov tuam txhab, cov tshuab thiab cov tshuab ua haujlwm tau hloov pauv cov ntawv ua haujlwm tag.

Keeb Kwm

Tus tsim PCB yog Austrian Paul Eisler (Paul Eisler), xyoo 1936, nws thawj zaug siv cov ntawv luam tawm Circuit board hauv xov tooj cua. Xyoo 1943, Neeg Amelikas feem ntau siv cov cuab yeej siv no rau xov tooj cua tub rog. Xyoo 1948, Tebchaws Meskas tau tso cai pom zoo qhov kev tsim no rau kev lag luam. Txij li thaum nruab nrab xyoo 1950, cov phiajcim luam tawm tau pib tsuas yog siv dav. Cov ntawv xov xwm hluav taws xob luam tawm tshwm hauv yuav luag txhua lub tshuab hluav taws xob. Yog tias muaj cov khoom siv hluav taws xob hauv qee yam khoom siv, lawv txhua tus tau teeb tsa ntawm PCBs ntawm ntau qhov sib txawv. Lub luag haujlwm tseem ceeb ntawm PCB yog txhawm rau txuas ntau yam khoom siv hluav taws xob rau hauv Circuit Court uas tau txiav txim siab ua ntej thiab ua lub luag haujlwm ntawm kev xa xov. Nws yog qhov tseem ceeb txuas hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob thiab raug hu ua "niam ntawm cov khoom siv hluav taws xob".
