Dab tsi yog qhov dig muag faus ntawm? Dab tsi yog qhov txiaj ntsig ntawm qhov muag tsis pom thiab faus vias hauv PCB tsim?

Hauv kev tsim PCB, ib lub ntsiab lus uas feem ntau ntsib yog qhov muag tsis pom thiab faus vias. Qhov zoo ntawm qhov muag tsis pom thiab faus vias, yuav ua li cas lawv tsim, thiab vim li cas nws thiaj li tseem ceeb rau kev ua haujlwm nrog cov kws tshaj lij PCB cov chaw tsim khoom uas paub yuav ua li cas ntxiv qhov muag tsis pom thiab faus vias mus rau lub rooj tsav xwm luam tawm.

Raws li ib txwm muaj, nws yog ib qho nyuaj rau mount tag nrho cov kev sib txuas uas yuav tsum tau ntawm PCB ntawm ib txheej. Txoj kev daws teeb meem no yog vias. Lawv yog cov zoo li zoo li lub thoob-zoo li tus conductive vias uas tso cai rau multilayer kev sib txuas ntawm Circuit Court boards. Txawm hais tias muaj ntau tshaj ib hom vias, ob yog cov siv ntau tshaj plaws. Ob txoj kev no yog dig muag vias thiab faus vias, uas muaj qee yam txiaj ntsig rau cov neeg siv PCBs.

Dab tsi yog qhov txawv ntawm qhov dig muag vias thiab faus vias? Lub qhov muag tsis pom ntawm yog ib qho ntawm cov txheej sab nraud rau sab hauv uas txuas lub rooj tsavxwm, txawm li cas los xij, nws tsis tuaj yeem nyob txhua lub sijhawm thoob plaws hauv PCB. Vias txuas sab hauv cov khaubncaws sab nraud povtseg yam tsis ncav cuag txheej txheej. Tsis tas li ntawd, muaj ib lub qhov ntawm qhov uas khiav vertically los ntawm tag nrho cov board thiab txuas tag nrho cov txheej. Lub tswv yim no yog qhov yooj yim, nkag siab, thiab tuaj yeem muab qee qhov zoo.

Dab tsi yog qhov txiaj ntsig ntawm qhov muag tsis pom thiab faus vias? Qee lub PCB boards yog tsim los ua me me, thiab lawv qhov chaw muaj tsawg. Yog li ntawd, qhov muag tsis pom thiab faus vias tuaj yeem muab ntau qhov chaw thiab xaiv rau lub phaj. Kev faus vias, piv txwv li, yuav pab kom muaj qhov chaw nyob ntawm lub rooj tsavxwm yam tsis muaj kev cuam tshuam rau cov khoom siv saum npoo av lossis cov kab nyob rau sab saud thiab qis. Qhov qhov muag tsis pom kev pab kom muaj qhov chaw ntau ntxiv. Lawv feem ntau siv rau pitch BGA Cheebtsam. Vim tias qhov muag tsis pom kev tsuas yog dhau los ntawm ib feem ntawm cov phaj nyias, qhov no kuj txhais tau tias cov teeb liab residue tuaj yeem raug txo.

Txawm hais tias dig muag vias thiab faus vias tuaj yeem siv rau ntau yam ntawm PCBs, lawv feem ntau yog siv hauv high-density interconnect PCBs lossis HDIs. HDI tuaj yeem muab kev hloov hluav taws xob zoo dua thiab cov txheej txheem siab dua. Nrog rau cov vias zais, qhov no kuj pab ua rau lub rooj tsavxwm me dua thiab sib dua, uas yog qhov tseem ceeb rau kev ua khoom siv hluav taws xob. Lawv feem ntau siv rau hauv cov khoom siv kho mob, khoos phis tawj, xov tooj ntawm tes, thiab cov khoom siv hluav taws xob me me hnav.

Thaum qhov muag tsis pom thiab faus vias tuaj yeem pab cov neeg xav tau, lawv kuj nce tus nqi ntawm PCB. Qhov no yog vim muaj kev ua haujlwm ntxiv uas yuav tsum tau ntxiv rau ntawm lub rooj tsavxwm thiab qhov yuav tsum tau kuaj thiab tsim khoom. Hais tias, siv lawv tsuas yog thaum koj xav tau tiag tiag; vim koj xav tau lub rooj tsavxwm uas yog ob qho tib si compact thiab muaj txiaj ntsig.

Yog li yuav ua li cas los tsim qhov muag tsis pom thiab faus vias? Vias tuaj yeem tsim ua ntej lossis tom qab lamination ntawm ntau txheej. Qhov muag tsis pom vias thiab faus vias ntxiv rau PCBs los ntawm kev drilling tsis ruaj khov heev. Nws yog ib qho tseem ceeb uas tus neeg tsim khoom paub thiab nkag siab qhov tob ntawm lub laum me ntsis. Yog tias lub qhov tob tob tsis txaus, tsis muaj kev sib txuas zoo. Yog tias lub qhov tob dhau lawm, lawv tuaj yeem degrade qhov zoo ntawm lub teeb liab lossis ua rau muaj kev cuam tshuam. Yog tias tej yam no tau tshwm sim, nws yuav ua tsis tau.

Rau qhov qhov muag tsis pom, cov ntaub ntawv sib txawv drilling yuav tsum tau txhais cov qhov. Qhov piv ntawm txoj kab uas hla ntawm lub qhov mus rau txoj kab uas hla ntawm lub laum yuav tsum sib npaug los yog tsawg tshaj qhov ntawd. Qhov me me qhov khoob, qhov me me qhov kev ncua deb ntawm txheej txheej thiab txheej sab hauv.

Thaum faus qhov, yuav tsum muaj cov ntaub ntawv sib txawv los ua txhua lub qhov. Vim tias lawv txuas nrog rau qhov sib txawv ntawm cov txheej txheem sab hauv ntawm lub rooj tsavxwm. Qhov sib piv ntawm qhov tob rau qhov laum txoj kab uas hla yuav tsum tsis txhob ntau tshaj 12. Yog tias nws loj dua li txoj kab uas hla no, lwm cov ntawv txuas yuav raug kov.

Nws raug nquahu kom ua rau PCB ua ke nrog cov khoom siv hluav taws xob siab heev. Qhov no yuav pab ua kom lub rooj tsavxwm tsim thiab kev tsim kho, suav nrog qhov muag tsis pom thiab faus vias. Kev tsis npaj los yog tsis muaj peev xwm koom tes nrog cov chaw tsim khoom siv hluav taws xob zoo tuaj yeem ua rau cov nqi nce ntxiv, yog li nco ntsoov nrhiav tus kws tshaj lij fabricator. Cov cuab yeej tshaj lij thiab cov kws tshaj lij kws tshaj lij yuav tsum tau ua kom ntseeg tau tias qhov tob tob tob. Shenzhen Beton Co., Ltd. yog ib tug high-precision PCB multi-layer Circuit Court board chaw tsim tshuaj paus, tsom rau zus tau tej cov PCB multi-layer boards, txhuas substrates, tooj liab substrates, ceramic boards, high-frequency boards, FPC mos boards thiab nruj -flex boards, HDI siab Txhua yam tshwj xeeb cov laug cam xws li kev sib txuas ceev ceev. Thaum lub sijhawm txheej txheem no, xyuas kom meej tias PCB tsis raug huab cua, thiab cov txheej txheem sab hauv yog coated zoo thiab txuas nrog.
