PCBs txhawb ntau lub lag luam thiab khoom siv hauv peb lub zej zog. Raws li peb cov thev naus laus zis hloov pauv, yog li qhov kev thov rau ntau hom PCBs. Thaum koj xaiv ntawm ib txheej thiab ntau txheej PCBs, cov kev xaiv zoo li tsis muaj qhov kawg. Ua ntej yuav PCB tshiab, nws yog ib qho tseem ceeb kom nkag siab qhov zoo thiab qhov tsis zoo ntawm txhua qhov kev xaiv. Nov yog qee qhov txiaj ntsig ntawm kev yuav khoom multilayer PCB ntawm ib-txheej tsim.

Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias PCB ntau txheej yog dab tsi thiab yuav ua li cas.

Ib txheej txheej PCB muaj txheej txheej ntawm cov khoom siv ua haujlwm. Koj yuav pom daim duab kab hluav taws xob txuas rau ntawm ib sab ntawm lub rooj tsavxwm thiab cov khoom sib txuas ntawm lwm qhov. Ib txheej PCBs ib leeg feem ntau siv hauv cov cuab yeej yooj yim vim tias tsis muaj xov hlau hla hla kom ua haujlwm tau zoo. Ob tog ob sab PCBs zoo ib yam, muaj haujlwm ntau dua li cov laug cam ib txheej, tab sis tsawg dua ntau txheej PCBs. Lawv tsuas muaj ib txheej dielectric thiab txheej txheej hlau ua rau txhua sab.

Cov laug cam ntau tus neeg, ntawm qhov tod tes, nyuaj dua li ib txheej lossis ob tog PCBs. Multilayer PCB muaj peb lossis ntau txheej ntawm cov khoom siv coj ua. Lwm cov txheej, feem ntau yog cov ntawv ci tooj liab, tau muab tso rau saum cov tub ntxhais.

Pib nrog cov tub ntxhais. Txhua txheej ntxiv txij thaum ntawd los tseem tsis tau kho zoo kiag li. In this way, the manufacturer can adjust them relative to the core. Tom qab ntawd, cov ntawv ci txuas ntxiv mus thiab tuaj yeem hloov pauv nrog lwm txheej los ntawm txheej txheem lamination. Cov txheej txheem siab thiab ntsuas kub yuav tsum tau siv los ua ke cov txheej thiab fuse lawv ua ke kom nyab xeeb.

Ib leeg thiab ntau txheej PCB

Multilayer PCBS muaj ntau yam txiaj ntsig. Zuag qhia tag nrho, cov laug cam no me dua thiab sib dua, uas ua rau lawv zoo tagnrho rau cov smartphones lossis khoos phis tawj, lossis lwm yam khoom lag luam uas xav tau ntim ntau yam. Nov yog qee qhov txiaj ntsig tshwj xeeb:

Ntau txheej PCB tso cai rau koj kom tau txais kev ua haujlwm ntau dua.

Kev sib sau ua ke siab txhais tau tias koj tuaj yeem txuas lub neej ntawm koj lub rooj tsavxwm.

Cov qauv no yooj yim dua thaum koj tsis xav tau cov txuas rau ntau yam ywj pheej PCBS.

LA cov txheej txheem ntsuas nruj ntawm theem tsim khoom txhais tau tias koj yuav tau txais cov khoom lag luam zoo, ua tau zoo.

Cov yam ntxwv hluav taws xob ntawm ntau txheej PCBS tau nrawm dua ib txheej txheej.

L Nyob ntawm seb muaj pes tsawg txheej uas koj xaiv los ntxiv, ntau txheej PCBS feem ntau yog qhov zoo rau cov txheej txheem nruj thiab hloov pauv tau.

Los ntawm qhov sib txawv, thaum ib txheej PCBS tau muaj txiaj ntsig hauv qee qhov kev thov, lawv kuj muaj qee qhov tsis zoo uas yuav tsum tsis txhob saib tsis taus. Nov yog qee qhov tsis zoo ntawm monolayers:

Vim tias cov xov hlau tsis tuaj yeem hla, cov laug cam ib txheej yog qhov zoo tshaj plaws rau cov khoom siv hluav taws xob yooj yim thiab tsis muaj ntau yam siv tau.

L Txawm hais tias ib txheej PCBS pheej yig dua rau kev tsim khoom, lawv tsis nyob ntev li ntev tau ntau txheej PCBS, txhais tau tias lawv tsis tshua muaj txiaj ntsig zoo.

Ib txheej PCBS tsis tuaj yeem ua tiav qhov nrawm ntawm lawv cov txheej txheem sib xyaw ua ke.

L Cov laug cam uas muaj ib txheej tau txwv rau lawv cov qauv tsim vim tias lawv tsuas muaj ib tus neeg coj thiab txhua kab yuav tsum muaj nws txoj hauv kev.

Txawm hais tias ib txheej PCBS yog qhov xaiv tau rau qhov tsim qauv qis, cov yam ntxwv ntawm ntau txheej PCBS ua rau lawv xaiv zoo tshaj plaws rau ntau lub lag luam nrhiav kom muaj kev ruaj khov thiab muaj ntau yam kev xaiv.

Kev siv ntau txheej PCB

Many industries and products can benefit from multi-layer PCBS, especially because of their durability, functionality, and lightness. Nov yog qee cov khoom lag luam uas nquag siv cov laug cam no:

L lub computer

L Lub plawv saib

L hluav taws

LGPS thiab satellite systems
