Kev tswj hwm tus nqi PCB yuav tsum tau nruj me ntsis kev tsim qauv, kev xa mus rau koj cov lus qhia tshwj xeeb rau cov neeg muag khoom, thiab tswj kev sib raug zoo nrog lawv.

Txhawm rau pab koj tawm, peb tau sau 8 lub tswv yim los ntawm cov neeg siv khoom thiab cov chaw muag khoom uas koj tuaj yeem siv los txo cov nqi tsis tsim nyog thaum tsim PCBs.

1.Xav txog qhov kom muaj nuj nqis thiab sab laj nrog cov chaw tsim khoom

Txawm hais tias ua ntej theem kawg ntawm kev tsim qauv engineering, kev sib tham nrog koj cov neeg muag khoom tuaj yeem tso cai rau koj pib sib tham thiab nkag siab txog cov teeb meem ntsig txog kev tsim khoom ntawm koj qhov project.

Txij thaum pib, xav txog koj qhov ntim los ntawm kev sau cov ntaub ntawv ntau npaum li koj tuaj yeem ua tau los ntawm koj cov neeg muab khoom: cov khoom tshwj xeeb, taug qab cov kev qhia tshwj xeeb, lossis kev ua siab ntev ntawm pawg thawj coj saib. Qhov kev xaiv tsis ncaj ncees tuaj yeem ua rau muaj ntau lub sijhawm nkim thiab tsim cov nqi tsis tsim nyog uas qhov tseeb tau txiav txim siab thaum ntxov ntawm cov qauv tsim. Yog li siv sij hawm los tham thiab ntsuam xyuas qhov zoo thiab qhov tsis zoo ntawm txhua qhov kev daws teeb meem muaj rau koj.

2.Minimize Circuit Board complexity

Qhov no yog tej zaum qhov yooj yim tshaj plaws los txo cov nqi PCB: optimize board tivthaiv kev tso kawm los ntawm cov qauv yooj yim. Koj tuaj yeem txo cov nqi los ntawm kev tsis siv cov ntaub ntawv nyuaj thiab txo qhov loj me, tab sis ceev faj, hauv qhov no nco ntsoov tso qhov chaw txaus ntawm txhua lub caij.

Cov ntaub ntawv nyuaj, tshwj xeeb tshaj yog cov tsis zoo, nce nqi. Sab hauv PCB txiav yog qhov zoo tshaj plaws zam tshwj tsis yog xav tau rau kev sib dhos zaum kawg. Cov chaw tsim khoom muab ib daim ntawv them nqi ntxiv rau txhua qhov kev txiav ntxiv. Ntau tus engineers nyiam qhov zoo li qub, tab sis nyob rau hauv lub ntiaj teb tiag tiag, qhov sib txawv no tsis cuam tshuam rau pej xeem cov duab thiab tsis ntxiv kev ua haujlwm.

3.Txhais qhov tseeb qhov loj thiab tuab

Board hom muaj kev cuam tshuam loj rau cov txheej txheem xaim: yog tias PCB me me thiab nyuaj, ntau lub sijhawm thiab kev siv zog yuav xav tau rau cov khoom sib dhos kom tiav. Qhov loj me me me yuav pheej yig heev. Yog li nws yog ib qho tseem ceeb kom txuag tau qhov chaw, peb pom zoo kom tsis txhob txo nws ntau tshaj qhov tsim nyog kom tsis txhob muaj ntau yam haujlwm ntawm tib lub rooj tsavxwm.

Ib zaug ntxiv, nco ntsoov tias cov ntaub ntawv nyuaj muaj feem cuam tshuam rau tus nqi: lub square lossis duab plaub PCB yuav tso cai rau koj kom tswj tau.

Qhov ntau PCB thickness yog nce, qhov siab dua cov nqi tsim khoom yuav ... nyob rau hauv txoj kev xav! Tus naj npawb ntawm cov khaubncaws sab nraud povtseg koj xaiv cuam tshuam rau Circuit Board vias (hom thiab txoj kab uas hla). Yog hais tias lub rooj tsavxwm yog thinner, tag nrho cov nqi ntawm lub rooj tsavxwm tuaj yeem raug txo, tab sis ntau qhov yuav xav tau, thiab qee lub tshuab qee zaum siv tsis tau nrog cov PCBs nyias. Tham nrog koj tus neeg muag khoom thaum ntxov yuav pab koj txuag nyiaj!

4. Kho qhov loj me thiab cov nplhaib

Cov kab loj loj thiab qhov yog qhov yooj yim tshaj plaws los tsim vim lawv tsis xav tau cov tshuab muaj tseeb. Ntawm qhov tod tes, cov me me yuav tsum muaj kev tswj xyuas ntau dua: lawv siv sijhawm ntev dua los ua thiab cov tshuab yuav kim dua, uas ua rau koj cov nqi tsim khoom PCB ntau dua.

5. Sib txuas lus cov ntaub ntawv kom meej li sai tau

Cov kws tsim khoom lossis cov neeg yuav khoom uas xaj lawv cov PCBs yuav tsum tuaj yeem xa lawv qhov kev thov kom meej raws li qhov ua tau, nrog cov ntaub ntawv tiav (cov ntaub ntawv Gerber suav nrog tag nrho cov txheej txheem, cov ntaub ntawv kuaj xyuas impedance, tshwj xeeb stackup, thiab lwm yam): nyob rau hauv txoj kev cov neeg muag khoom tsis tas yuav tsum tau txhais lus. thiab kev siv sij hawm siv nyiaj ntau thiab cov nqi kho mob yuav raug zam.

Thaum cov ntaub ntawv ploj lawm, cov neeg muag khoom yuav tsum tuaj yeem tiv tauj lawv cov neeg siv khoom, nkim lub sijhawm muaj txiaj ntsig uas tuaj yeem siv rau lwm qhov haujlwm.
Thaum kawg, cov ntaub ntawv ntshiab ua rau nws muaj peev xwm txheeb xyuas qhov ua tsis tiav kom tsis txhob muaj kev puas tsuaj thiab ua rau cov neeg siv khoom txaus siab.

6.Optimise paneling

Qhov zoo tshaj plaws kev faib tawm ntawm lub vaj huam sib luag ntawm lub vaj huam sib luag tseem ua lub luag haujlwm tseem ceeb: txhua millimeter ntawm qhov chaw siv qhov chaw tsim cov nqi, yog li nws zoo dua tsis txhob tawm ntau qhov chaw ntawm qhov sib txawv. Nco ntsoov tias qee cov khoom tuaj yeem sib tshooj thiab xav tau qhov chaw ntxiv. Yog tias paneling nruj dhau lawm, qee zaum yuav tsum tau siv phau ntawv soldering uas ua rau muaj nqi ntau ntxiv.

7.Xaiv hom kev ntawm
Kev nkag ntawm vias yog pheej yig dua, qhov qhov muag tsis pom lossis cov qhov embedded tsim cov nqi ntxiv. Cov no tsuas yog xav tau nyob rau hauv complex, siab ceev los yog siab zaus boards.

Tus naj npawb ntawm vias thiab lawv hom muaj feem cuam tshuam rau cov nqi tsim khoom. Multilayer boards feem ntau xav tau me me txoj kab uas hla.

8. Rov xav txog koj cov kev yuav khoom

Thaum koj tau ua tiav tag nrho koj cov nqi, koj tuaj yeem tshuaj xyuas koj qhov kev yuav khoom thiab ntau npaum li cas. Los ntawm kev txiav txim pab pawg koj tuaj yeem txuag tau nyiaj ntau. Piv txwv li, yog tias koj yuav ib puas circuits nees nkaum zaug hauv ib xyoos, koj tuaj yeem txiav txim siab hloov qhov zaus los ntawm tsuas yog xaj tsib zaug hauv ib xyoos.

Ceev faj tsis txhob khaws cia rau ntev heev txawm tias vim muaj kev pheej hmoo ntawm kev lwj.

Tam sim no koj paub yuav ua li cas kho koj cov nqi PCB kom ntau li ntau tau. Ceev faj, vim qee zaum, kev txuag nyiaj ntawm kev tsim hluav taws xob luam tawm yuav tsis yog ib lub tswv yim zoo. Txawm hais tias cov nqi raug txo qis rau kev tsim khoom thawj zaug, lawv yuav kim dua nyob rau lub sijhawm ntev: koj tsis tuaj yeem paub tseeb tias koj yuav tsis tas yuav hloov cov laug cam ntau zaus… Koj tseem yuav tau tswj cov neeg siv khoom tsis txaus siab thiab nrhiav kev daws teeb meem tshiab tom qab. nyob rau kom tsis txhob poob no.

Txawm koj xaiv dab tsi, thaum kawg, qhov kev daws teeb meem zoo tshaj plaws los tswj cov nqi yog ib txwm sib tham nrog koj cov neeg muag khoom. Lawv yuav tuaj yeem muab cov ntaub ntawv tseem ceeb thiab raug rau koj kom ua tau raws li koj xav tau. Lawv tuaj yeem pab koj cia siab tias muaj ntau yam kev nyuaj uas koj yuav ntsib thiab yuav txuag koj lub sijhawm muaj nuj nqis.
