Tus tsim ntawm PCB pawg thawj coj saib feem ntau muaj cov teeb meem zoo li no thiab? Hnub no kuv nyiam txoj haujlwm network xiaobian pom zoo tsab xov xwm no koom nrog PCB pawg thawj coj tsim rau ntau xyoo ntawm cov kws tsim txuj ci, luam tawm Circuit board tsim kev paub los qhia rau koj. Txais tos kom sau!

Rau cov khoom siv hluav taws xob, PCB pawg thawj coj tsim yog txheej txheem tsim nyog los ntawm daim duab hluav taws xob kos duab rau ib yam khoom tshwj xeeb, thiab qhov tsim nyog ntawm nws cov qauv tsim muaj feem cuam tshuam nrog kev tsim khoom thiab cov khoom lag luam zoo. Txawm li cas los xij, rau ntau tus neeg uas nyuam qhuav koom nrog tsim hluav taws xob, lawv muaj kev paub me ntsis hauv qhov no. Txawm hais tias lawv tau kawm PCB board tsim software, Tab sis PCB tsim ntau zaus muaj qee qhov teeb meem. Tus kws tshaj lij pom zoo los ntawm Xiaobian tau koom nrog PCB pawg thawj coj tsim ntau xyoo. Nws/nws yuav qhia nws qhov kev paub dhau los hauv PRINTED Circuit board tsim nrog koj, vam tias yuav ua lub luag haujlwm ntawm kev pov cov cib kom nyiam jade. PCB tsim software pom zoo los ntawm tus kws tshaj lij yog TANGO ob peb xyoos dhau los, thiab tam sim no siv PROTEL2.7 RAU WINDOWS.

Muaj txheej PCB

Qhov kev txiav txim ib txwm tso rau ntawm cov khoom ntawm PCB:

1, tso cov khoom siv nrog txoj haujlwm ruaj khov nrog cov qauv, xws li lub qhov hluav taws xob, lub teeb pom kev, hloov pauv, txuas, thiab lwm yam. tsiv los ntawm kev ua yuam kev;

2, cov khoom tshwj xeeb thiab cov khoom loj tso rau ntawm kab, xws li cov cua sov, cov hloov pauv, IC, thiab lwm yam;

3. Muab cov cuab yeej me me.

Qhov nrug nruab nrab ntawm qhov tivthaiv thiab ntug ntawm PCB

Yog tias ua tau, txhua qhov khoom siv yuav tsum tau muab tso rau hauv 3mm los ntawm ntug ntawm PCB pawg thawj coj lossis tsawg kawg ntau dua li cov tuab ntawm PCB pawg thawj coj. Qhov no yog vim tias hauv kev tsim khoom loj ntawm cov kab sib dhos ua ke ntsaws thiab yoj yoj, nws yuav tsum tau muab rau phau ntawv qhia kev siv. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv qhov tsis xws luag tshwm sim los ntawm kev ua cov duab, yog tias muaj ntau yam khoom siv ntawm PCB pawg thawj coj, Yog tias koj yuav tsum mus dhau 3mm ntau, koj tuaj yeem ntxiv 3mm ntu ntu txuas mus rau ntug ntawm pawg thawj coj saib xyuas PCB, thiab qhib V-shaped slot rau ntawm ntug kev pabcuam, uas tuaj yeem tawg ntawm tes thaum tsim khoom.

Kev sib cais ntawm siab thiab qis

Muaj cov hluav taws xob hluav taws xob muaj hluav taws xob tsawg thiab hluav taws xob hluav taws xob tsawg nyob rau tib lub sijhawm ntawm ntau lub rooj tsav xwm PCB, cov khoom siv hluav taws xob hluav taws xob siab thiab qhov hluav taws xob qis yuav tsum raug cais thiab qhib, thiab qhov kev sib cais yog cuam tshuam nrog kev tiv thaiv hluav taws xob. Feem ntau, PCB pawg thawj coj yuav tsum yog 2 hli deb ntawm qhov ntsuas hluav taws xob ntawm 2000kV, thiab kev faib ua feem saum toj no yuav tsum tau nce ntxiv, piv txwv li, yog tias qhov ntsuas qhov ntsuas hluav taws xob yog 3000V, Qhov nrug nruab nrab ntawm cov kab hluav taws xob siab thiab qis yuav tsum ntau dua 3.5mm, ntau zaus kom tsis txhob nkag mus, tab sis kuj tseem nyob hauv PCB pawg thawj coj ntawm qhov siab thiab qis qhov hluav taws xob.

Cov kab hluav taws xob PCB

Cov txheej txheem ntawm cov ntawv luam tawm yuav tsum luv li sai tau, tshwj xeeb tshaj yog nyob hauv cov xov tooj cua ntau zaus; Kev xa cov xov hlau yuav tsum tau muab sib npaug, thiab Lub kaum sab xis lossis lub kaum ntse ntse yuav cuam tshuam rau kev ua haujlwm hluav taws xob thaum muaj hluav taws xob ntau hauv lub xov tooj thiab txuas qhov sib txuas; Thaum txuas ob lub vaj huam sib luag, cov xov hlau ntawm ob sab yuav tsum tau nyob ib puag ncig, oblique, lossis khoov kom tsis txhob sib txig sib luag kom txo cov kab mob sib kis. Luam cov xov hlau uas siv los ua tswv yim thiab tso tawm ntawm Circuit yuav tsum raug zam kom sib thooj ib leeg kom deb li deb tau kom tsis txhob tawm tswv yim. Nws yog qhov zoo tshaj los ntxiv cov xov hluav taws xob hauv av ntawm cov xov hlau no.

Dav ntawm cov xov hlau

Qhov dav ntawm cov xaim yuav tsum ua tau raws li qhov xav tau ntawm kev ua hluav taws xob thiab yooj yim rau kev tsim khoom. Nws tus nqi yam tsawg kawg yog nyob ntawm qhov loj ntawm tam sim no, tab sis qhov tsawg kawg yuav tsum tsis pub tsawg dua 0.2mm. In high density, high precision printed lines, wire width and spacing is generally desirable 0.3mm; Qhov kub nce ntawm cov dav hlau yuav tsum raug txiav txim siab thaum muaj qhov siab tam sim no. Ib qho kev sim ua vaj huam sib luag qhia pom tias thaum tuab tuab ntawm cov ntawv ci tooj liab yog 50μm, qhov dav ntawm xaim yog 1 ~ 1.5mm thiab qhov tam sim no yog 2A, qhov kub tau nce me me. Yog li ntawd, xaim nrog qhov dav ntawm 1 ~ 1.5mm tuaj yeem ua tau raws li qhov yuav tsum tau ua yam tsis ua rau kub nce.

Cov xov hlau hauv av rau cov luam ntawv yuav tsum yog tuab li sai tau, siv cov kab loj dua 2 txog 3mm yog tias ua tau, tshwj xeeb tshaj yog hauv kev sib txuas nrog microprocessors. Vim tias txoj kab hauv nroog tau zoo heev, vim qhov kev hloov pauv ntawm cov dej ntws tam sim no, kev hloov pauv hauv av, microprocessor lub sijhawm teeb liab teeb tsa tsis xwm yeem, yuav ua rau lub suab nrov tsis zoo zuj zus tuaj; Cov txheej txheem 10-10 thiab 12-12 tuaj yeem siv tau thaum txuas ntawm DIP ntim IC pins, uas yog, thaum ob lub xov hlau hla ntawm tus pin, lub ncoo txoj kab tuaj yeem teeb rau 50mil, kab dav thiab kab sib nrug yog 10mil, thaum tsuas yog ib txoj xov hlau hla ntawm tus pin, txoj kab uas hla tuaj yeem teeb tau rau 64mil, kab dav thiab kab sib nrug yog 12mil.

Qhov sib txawv ntawm cov xov hlau uas tau luam tawm

Qhov sib nrug ntawm cov xov nyob ib sab yuav tsum ua tau raws li qhov xav tau ntawm kev nyab xeeb hluav taws xob, thiab kom yooj yim ntawm kev ua haujlwm thiab kev tsim khoom, qhov sib nrug yuav tsum yog dav li ntau tau. Qhov nrug tsawg kawg yuav tsum yog yam tsawg haum rau qhov hluav taws xob kom ruaj khov. Qhov hluav taws xob no feem ntau suav nrog kev ua haujlwm voltage, qhov hloov pauv ntxiv thiab qhov siab tshaj qhov tshwm sim los ntawm lwm yam.

Yog tias cov txheej txheem kev tso cai qee qib ntawm cov hlau seem ntawm cov xov hlau, qhov sib nrug yuav raug txo kom tsawg. Yog li tus tsim qauv yuav tsum coj tus lej no rau hauv tus account thaum txiav txim siab qhov hluav taws xob. Thaum thaiv cov kab hluav taws xob qis dua, qhov sib nrug ntawm kab teeb liab tuaj yeem tsim nyog ntxiv, kab teeb liab nrog qhov sib txawv ntawm qhov siab, qib qis yuav tsum luv kom deb li deb tau thiab nce qhov sib nrug.

Kev tiv thaiv thiab av ntawm cov xov hlau luam tawm

Cov pej xeem hauv av ntawm cov xov hlau yuav tsum tau npaj rau ntawm ntug ntawm lub rooj tsav xwm luam tawm kom deb li deb tau. Ntau cov ntawv tooj liab ntau li ntau tau yuav tsum tau khaws tseg raws li cov hlau hauv av ntawm PCB pawg thawj coj, yog li cov txiaj ntsig tiv thaiv tau zoo dua li cov xov hlau hauv av ntev, cov kab sib kis thiab cov yam ntxwv tiv thaiv yuav raug txhim kho, thiab tseem ua lub luag haujlwm txo qis kev faib tawm. Cov pej xeem hauv av ntawm cov xov hlau uas luam tawm yog qhov zoo tshaj plaws los ua lub voj lossis network, vim tias thaum muaj ntau qhov kev sib txuas ntawm ib lub rooj tsavxwm, tshwj xeeb tshaj yog thaum muaj cov khoom siv uas siv hluav taws xob ntau dua, qhov txwv ntawm daim duab ua rau lub hauv paus muaj peev xwm sib txawv, uas ua rau txo qis suab nrov kam rau ua, thaum nws dhau los ua lub voj, qhov ua kom muaj peev xwm sib txawv hauv av tau txo.

Ib qho ntxiv, daim duab hauv av thiab lub zog yuav tsum yog sib npaug rau cov lus qhia ntawm cov ntaub ntawv kom deb li deb tau, uas yog qhov zais cia ntawm kev muaj peev xwm tiv thaiv suab nrov; Multilayer PCB board tuaj yeem siv ob peb txheej ua txheej tiv thaiv, txheej khoom siv hluav taws xob, txheej av hauv av tuaj yeem suav tias yog txheej txheej tiv thaiv, txheej txheej hauv av thiab txheej txheej hluav taws xob tau tsim nyob hauv txheej sab hauv ntawm ntau pawg PCB pawg thawj coj, teeb liab kab tsim sab hauv thiab txheej txheej.
