Lub rooj tsav xwm PCB tuaj yeem muab ntau yam khoom siv hluav taws xob ua ke, uas tuaj yeem txuag tau qhov chaw zoo heev thiab yuav tsis cuam tshuam rau kev ua haujlwm ntawm lub voj voog. Muaj ntau cov txheej txheem hauv kev tsim ntawm PCB Circuit Board. Ua ntej, peb yuav tsum teem caij Tshawb xyuas qhov tsis sib xws ntawm PCB Circuit Board. Qhov thib ob, peb yuav tsum ua kom haum rau ntau qhov chaw hauv lawv txoj haujlwm kom raug.

1. Nkag mus rau hauv PCB tsim system thiab teeb tsa cov kev cuam tshuam

Teem ib puag ncig tsis zoo ntawm cov qauv tsim raws li tus kheej tus cwj pwm, xws li qhov loj thiab hom ntawm daim phiaj taw tes, qhov loj thiab hom ntawm tus cursor, thiab lwm yam. Feem ntau hais lus, lub neej ntawd tus nqi yuav siv tau. Tsis tas li ntawd, cov kev txwv xws li qhov loj thiab tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm yuav tsum tau teeb tsa.

2. Tsim lub rooj sib tham sib txawv

Lub rooj sib tham hauv lub network yog tus choj thiab kev sib txuas ntawm cov qauv tsim hluav taws xob thiab cov ntawv luam tawm Circuit Board tsim, uas yog qhov tseem ceeb heev. Cov netlist tuaj yeem tsim los ntawm daim duab kos duab kos duab, lossis tuaj yeem muab rho tawm los ntawm cov ntaub ntawv luam tawm Circuit Board uas twb muaj lawm. Thaum lub rooj sib tham hauv lub network tau qhia, nws yog qhov yuav tsum tau kuaj xyuas thiab kho qhov yuam kev hauv Circuit Court schematic tsim.

3. Npaj qhov chaw ntawm txhua feem pob

Kev siv lub tshuab ua haujlwm tsis siv neeg tuaj yeem siv tau, tab sis qhov kev ua haujlwm tsis siv neeg layout tsis zoo tag nrho, thiab nws yog qhov tsim nyog los kho qhov chaw ntawm txhua pob khoom.

4. Ua cov kab hluav taws xob hauv Circuit Court

Lub hauv paus ntawm kev ua haujlwm ntawm lub rooj tsav xwm tsis siv neeg yog los teeb tsa kev nyab xeeb, daim ntawv xaim thiab lwm yam ntsiab lus. Tam sim no, tsis siv neeg thaiv kev ua haujlwm ntawm cov cuab yeej siv tau ua tiav, thiab daim duab kos duab dav dav tuaj yeem raug xa mus; tab sis qhov kev teeb tsa ntawm qee cov kab tsis txaus siab, thiab kev xaim kuj tuaj yeem ua tiav manually.

5. Txuag los ntawm lub tshuab luam ntawv tso zis lossis daim ntawv nyuaj

Tom qab ua tiav cov xaim hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court, khaws cov ntaub ntawv ua tiav daim duab kos, thiab tom qab ntawd siv ntau yam duab tso zis, xws li cov tshuab luam ntawv lossis cov tshuab hluav taws xob, los tso tawm cov kab hluav taws xob ntawm lub rooj tsav xwm Circuit Court.

Electromagnetic compatibility yog hais txog lub peev xwm ntawm cov khoom siv hluav taws xob los ua haujlwm sib haum xeeb thiab ua tau zoo hauv ntau qhov chaw electromagnetic. Lub hom phiaj yog ua kom cov khoom siv hluav taws xob los tiv thaiv ntau yam kev cuam tshuam sab nraud, ua kom cov khoom siv hluav taws xob ua haujlwm ib txwm nyob hauv ib puag ncig electromagnetic, thiab tib lub sij hawm txo cov electromagnetic cuam tshuam ntawm cov khoom siv hluav taws xob nws tus kheej mus rau lwm cov khoom siv hluav taws xob. Raws li tus neeg muab kev pabcuam kev sib txuas hluav taws xob rau cov khoom siv hluav taws xob, qhov kev sib raug zoo ntawm PCB Circuit Board yog dab tsi?

1. Xaiv qhov dav hlau tsim nyog. Txij li qhov cuam tshuam cuam tshuam los ntawm qhov tam sim no nyob rau ntawm cov ntawv luam tawm ntawm PCB Circuit Board feem ntau yog tshwm sim los ntawm cov khoom siv hluav taws xob ntawm cov ntawv luam tawm, qhov inductance ntawm cov ntawv luam tawm yuav tsum raug txo kom tsawg.

2. Raws li qhov nyuaj ntawm lub voj voog, kev xaiv tsim nyog ntawm PCB txheej txheej tuaj yeem txo qhov cuam tshuam ntawm electromagnetic cuam tshuam, txo qhov ntim ntawm PCB thiab qhov ntev ntawm lub voj tam sim no thiab ceg thaiv, thiab txo qis kev cuam tshuam ntawm cov teeb liab.

3. Kev siv txoj hlua hluav taws xob kom raug thiab siv cov xaim sib npaug tuaj yeem txo qhov inductance ntawm cov xov hlau, tab sis kev sib nrig sib inductance thiab kev faib cov peev txheej ntawm cov xov hlau yuav nce. Yog tias qhov layout tso cai, nws yog qhov zoo tshaj plaws los siv cov qauv mesh zoo zoo. Txoj kev tshwj xeeb yog ua rau ib sab ntawm cov ntawv luam tawm kab rov tav Wiring, xaim ntawm lwm sab vertically, thiab tom qab ntawd txuas nrog cov qhov metallized ntawm qhov cross qhov.

4. Txhawm rau txhawm rau tiv thaiv kev sib tham ntawm cov xov hlau ntawm PCB Circuit Board, sim ua kom tsis txhob muaj qhov sib npaug sib npaug ntawm cov xaim ntev thaum tsim cov xov hlau, thiab khaws qhov kev ncua deb ntawm cov xov hlau kom deb li deb tau. ntoo khaub lig. Kev teeb tsa cov kab ntawv sau hauv av ntawm qee cov kab teeb liab uas nkag siab zoo rau kev cuam tshuam tuaj yeem cuam tshuam crosstalk zoo
