Weiwenxin PCBworld] Hauv kev tshawb fawb ntawm PCB thim rov qab thev naus laus zis, thim rov qab lub hauv paus ntsiab lus hais txog kev rov qab thawb tawm raws li cov ntaub ntawv PCB kos duab lossis kos duab ncaj qha rau PCB daim duab kos raws li cov khoom siv tiag tiag, uas yog lub hom phiaj los piav qhia lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm lub voj voog. lub rooj tsavxwm.Ntxiv mus, daim duab kos duab no tseem siv los txheeb xyuas cov yam ntxwv ntawm cov khoom nws tus kheej.Hauv kev tsim qauv, kev tsim cov khoom lag luam dav dav yuav tsum ua ntej ua tus qauv tsim, thiab tom qab ntawd ua tiav cov qauv PCB raws li schematic.

Txawm hais tias nws yog siv los txheeb xyuas lub hauv paus ntsiab lus ntawm Circuit Court board thiab cov yam ntxwv ntawm cov khoom lag luam hauv kev tshawb fawb rov qab, lossis rov qab siv los ua lub hauv paus thiab lub hauv paus ntawm PCB tsim hauv kev tsim qauv, PCB schematics muaj lub luag haujlwm tshwj xeeb.Yog li, yuav ua li cas thim rov qab PCB schematic daim duab raws li daim duab kos duab lossis cov khoom tiag?Cov ntsiab lus dab tsi yuav tsum tau them nyiaj rau thaum lub sij hawm rov qab xam cov txheej txheem?

Tsim nyog faib cov chaw ua haujlwm
01

Thaum ua qhov rov qab tsim qauv ntawm daim duab schematic ntawm lub rooj tsav xwm PCB zoo, kev faib ua haujlwm tsim nyog tuaj yeem pab cov engineers txo qee qhov teeb meem tsis tsim nyog thiab txhim kho kev ua haujlwm ntawm kev kos duab.Feem ntau hais lus, cov khoom siv nrog tib lub luag haujlwm ntawm PCB lub rooj tsavxwm tau teeb tsa hauv qhov tseem ceeb, thiab kev faib ntawm thaj chaw los ntawm kev ua haujlwm tuaj yeem muaj lub hauv paus yooj yim thiab raug thaum hloov pauv daim duab schematic.

Txawm li cas los xij, kev faib ntawm thaj chaw ua haujlwm no tsis yog arbitrary.Nws xav kom engineers kom muaj kev nkag siab txog kev paub txog hluav taws xob hluav taws xob.Ua ntej, nrhiav cov ntsiab lus tseem ceeb hauv ib chav haujlwm ua haujlwm, thiab tom qab ntawd raws li kev sib txuas ntawm kev sib txuas, koj tuaj yeem nrhiav lwm cov khoom ntawm tib lub zog ua haujlwm raws txoj hauv kev los tsim ib qho kev faib ua haujlwm.Qhov tsim ntawm kev ua haujlwm partitions yog lub hauv paus ntawm kev kos duab schematic.Tsis tas li ntawd, nyob rau hauv cov txheej txheem no, tsis txhob hnov ​​​​qab siv cov lej xov tooj ntawm cov khoom ntawm lub rooj tsav xwm Circuit Court ntse, lawv tuaj yeem pab koj faib cov haujlwm sai dua.

Kho qhov sib txawv ntawm cov kab thiab kos cov kab tsim nyog
02

Rau qhov sib txawv ntawm cov xaim hauv av, cov xaim hluav taws xob, thiab cov teeb liab xaim, cov kws ua haujlwm yuav tsum muaj kev paub txog kev siv hluav taws xob, kev paub txog kev sib txuas hauv hluav taws xob, kev paub txog PCB thaiv, thiab lwm yam.Qhov txawv ntawm cov kab no tuaj yeem txheeb xyuas raws li kev sib txuas ntawm cov khoom sib txuas, qhov dav ntawm cov ntawv ci tooj liab ntawm cov kab, thiab cov yam ntxwv ntawm cov khoom siv hluav taws xob nws tus kheej.

Hauv kev kos duab, txhawm rau kom tsis txhob hla thiab sib cuam tshuam ntawm cov kab, ntau cov cim hauv av tuaj yeem siv rau cov kab hauv av.Ntau cov kab tuaj yeem siv cov xim sib txawv thiab cov kab sib txawv los xyuas kom meej tias lawv paub meej thiab txheeb xyuas tau.Rau ntau yam khoom siv, cov cim tshwj xeeb tuaj yeem siv tau, lossis txawm tias Kos cov khoom siv hluav taws xob sib cais thiab sib xyaw ua ke thaum kawg.

Nrhiav cov khoom siv zoo

Qhov kev siv no kuj tseem tuaj yeem hais tias yog lub ntsiab lus tseem ceeb siv thaum pib ntawm daim duab schematic.Tom qab qhov kev siv ib feem raug txiav txim siab, qhov kev siv ib feem yog kos raws li tus pins ntawm cov khoom siv no, uas tuaj yeem ua kom qhov tseeb ntawm cov duab kos rau ntau dua.

Rau cov engineers, kev txiav txim siab ntawm cov khoom siv tsis yog qhov nyuaj heev.Raws li ib txwm muaj, cov khoom siv uas ua lub luag haujlwm tseem ceeb hauv Circuit Court tuaj yeem raug xaiv los ua cov khoom siv.Lawv feem ntau loj dua thiab muaj ntau tus pins, uas yooj yim rau kev kos duab.Xws li integrated circuits, transformers, transistors, thiab lwm yam, tuaj yeem siv raws li cov khoom siv tsim nyog.

Kawm paub lub hauv paus ntsiab lus thiab kawm los ntawm cov duab schematic zoo sib xws

Rau qee qhov yooj yim hluav taws xob Circuit Court thav duab muaj pes tsawg leeg thiab cov qauv kev kos duab, engineers yuav tsum paub, tsis yog tsuas yog tuaj yeem kos ncaj qha rau qee qhov yooj yim thiab classic unit circuits, tab sis kuj tsim tag nrho cov qauv ntawm hluav taws xob circuits.

Ntawm qhov tod tes, tsis txhob hnov ​​​​qab tias tib yam khoom siv hluav taws xob muaj qee qhov zoo sib xws hauv daim duab schematic.Cov kws tshaj lij tuaj yeem siv qhov sib xyaw ntawm cov kev paub dhau los thiab kawm tiav los ntawm cov duab kos duab zoo sib xws los thim rov qab cov duab kos duab ntawm cov khoom tshiab.

Xyuas thiab optimize
