Kev ceev faj rau PCB board tooj liab plating

Pcb Circuit Board tsim thiab ntau lawm muaj cov txheej txheem thiab kev ceev faj, pcb Circuit Court board tooj liab

yog ib kauj ruam tseem ceeb hauv kev tsim pcb, nrog rau cov ntsiab lus tshwj xeeb, ces yuav ua li cas ua qhov no ntawm tus tsim

ua haujlwm, Kuv Cov engineers laus ntawm lub tuam txhab tau tham thiab sau cov ntsiab lus hauv qab no, vam tias yuav br-

muaj txiaj ntsig rau txhua tus.

Copper txheej taw qhia:

Lub npe hu ua tooj liab txheej yog siv qhov chaw tsis siv ntawm PCB raws li qhov chaw siv, thiab tom qab ntawd sau nws.

nrog cov khoom siv tooj liab. Cov chaw tooj liab no tseem hu ua tooj liab filling. Qhov tseem ceeb ntawm tooj liab clad yog liab-

uce hauv av kab impedance, txhim kho lub peev xwm tiv thaiv kev cuam tshuam; txo qhov voltage poob, txhim kho lub

kev siv hluav taws xob zoo; txuas nrog rau hauv av xaim, thiab kuj txo cov voj voog cheeb tsam. Kuj rau lub hom phiaj

ntawm kev ua cov PCB soldered ntau npaum li qhov ua tau, feem ntau cov tuam txhab PCB tseem yuav xav tau PCB tsim-

er los sau cov tooj liab lossis kab sib chaws zoo li hauv av hauv thaj chaw qhib ntawm PCB. Yog hais tias tus tooj liab tsis raug kho kom raug,

ly, nws yuav Yog tias koj tsis txaus siab rau nws, nws puas yog "cov txiaj ntsig zoo dua qhov tsis zoo" lossis "ua rau muaj kev phom sij ntau dua

zoo"?

Txhua leej txhua tus paub hais tias nyob rau hauv high zaus, qhov kev faib capacitance ntawm cov xov hluav taws xob nyob rau hauv lub luam Circuit Court bo-

ard yuav ua haujlwm. Thaum qhov ntev yog ntau dua 1/20 ntawm qhov sib thooj wavelength ntawm lub suab nrov zaus,

ib qho kev cuam tshuam kav hlau txais xov yuav tshwm sim thiab lub suab nrov yuav raug tso tawm los ntawm kev xaim. Yog tias muaj kev sib koom ua ke tsis zoo,

pper nyob rau hauv PCB, tooj liab yog ib qho cuab yeej rau propagating suab nrov. Yog li ntawd, nyob rau hauv high-frequency circuits, tsis txhob xav li ntawd

qhov chaw nyob rau hauv av yog grounded. Qhov no yog av. "Line" yuav tsum tau ua nrog ib lub qhov ntawm cov xov hlau ntawm a

pitch tsawg tshaj li λ/20, thiab "zoo grounding" nrog rau hauv av dav hlau ntawm multilayer board. Yog tias lub tsho tiv no-

g yog kho kom zoo, cov tooj liab cladding tsis tsuas yog muaj qhov nce tam sim no, tab sis kuj plays ob lub luag haujlwm ntawm cov ntaub thaiv npog-

hauv kev cuam tshuam.

Hauv tooj liab cladding, txhawm rau ua tiav cov txiaj ntsig xav tau ntawm tooj liab cladding, muaj qee qhov teeb meem yuav tsum paub.

nyob rau hauv tooj liab cladding:

Yog hais tias lub PCB muaj ntau hauv av, muaj SGND, AGND, GND, thiab lwm yam, raws li qhov sib txawv ntawm PCB board po

-sition, qhov tseem ceeb tshaj plaws "hauv av" raws li cov ntaub ntawv siv rau cais tooj liab, digital av thiab analogg-

puag ncig Sib cais tooj liab los npog, thiab tib lub sijhawm, ua ntej txheej tooj liab, thawj zaug nce corresp-

onding fais fab kev twb kev txuas: 5.0V, 3.3V, thiab lwm yam., yog li tsim ib tug ntau ntawm cov duab sib txawv ntawm multi-deformation st-

pob txha.

2. Rau ib qho kev sib txuas rau qhov chaw sib txawv, txoj kev yog txuas los ntawm 0 ohm resistors lossis sib nqus

hlaws los yog inductors;

3. Cov tooj liab nyob ze ntawm cov siv lead ua oscillator, cov siv lead ua oscillator nyob rau hauv Circuit Court yog ib tug high-frequency emission qhov chaw, t-

nws txoj kev yog los puag ncig cov siv lead ua tooj liab, thiab tom qab ntawd cov siv lead ua casing yog grounded nyias.

4. Qhov teeb meem ntawm cov Islands tuaj cais (qhov chaw tuag), yog tias koj xav tias zoo heev, nws yuav tsis raug nqi ntau los txhais ib lub qhov hauv lub qhov.

5. Thaum pib xaim, cov xaim hauv av yuav tsum tau kho kom sib npaug. Thaum cov hlau raug xa mus, cov xaim hauv av

yuav tsum tau noj zoo. Nws tsis tuaj yeem cia siab rau tooj liab ntxiv rau ntawm lub qhov kom tshem tawm tus pin hauv av. Qhov no h-

raws li kev phem.

6. Nws yog qhov zoo tshaj kom tsis txhob muaj cov kaum ntse ntse ntawm lub rooj tsavxwm ("180 degrees"), vim hais tias los ntawm cov electromagnetic point ntawm vi-

ew, qhov no yog lub kav hlau txais xov xa xov! Rau lwm yam, yuav ib txwm muaj kev cuam tshuam txog seb nws loj lossis

me me. Txawm li cas los xij, kuv pom zoo kom siv cov ntug ntawm lub arc.

7. Cov xaim ntawm nruab nrab txheej ntawm cov txheej txheem ntau txheej tsis yog tooj liab. Vim nws nyuaj heev rau

koj ua qhov no tooj liab "zoo grounding"

8. Cov hlau hauv cov khoom siv, xws li hlau radiators, hlau reinforcement strips, thiab lwm yam, yuav tsum ua tiav "zoo g-

puag ncig".

9. Lub tshav kub-dissipating hlau thaiv ntawm peb lub davhlau ya nyob twg regulator yuav tsum tau zoo grounded. Kev sib cais hauv av

sawb nyob ze ntawm cov siv lead ua yuav tsum tau zoo grounded. Hauv luv luv: tooj liab ntawm PCB, yog tias muaj teeb meem hauv av,

nws yuav tsum yog "profits outweigh qhov tsis zoo", nws muaj peev xwm txo qhov rov qab cheeb tsam ntawm lub teeb liab kab, thiab txo cov exter-

nal electromagnetic cuam tshuam ntawm lub teeb liab.

Lwm cov lus hais muaj xws li "Yuav ua li cas yog qhov corrosion ntawm pcb Circuit Court board?" "PCB Circuit Board manufacturing thiab pa-

ckaging txheej txheem" ​​PCB board tsim thiab ntau lawm yuav tsum tau ib tug npaum li cas ntawm cov ntsiab lus, yog li yog tias koj xav tau

ua qhov no zoo, koj yuav tsum kawm los ntawm kev kawm tas li. Nrog rau kev sib sau ntawm kev paub, peb tuaj yeem maj mam pl-

ib rau nws.
