Khoom Paub meej
Multilayer PCB muaj ob los yog ntau dua conductive tooj liab txheej sib cais los ntawm dielectric cov ntaub ntawv thiab laminated ua ke, interconnected los ntawm plated los ntawm - qhov, faus vias los yog dig muag vias. Piv nrog rau ib qho -sab thiab ob -sab PCBs, multilayer PCBs zoo heev nthuav routing muaj peev xwm, txhim kho electromagnetic cuam tshuam shielding thiab txhawb complex high-ceev circuit designs. Lawv tau siv dav hauv cov khoom siv hauv kev lag luam, suav cov khoom siv, cov khoom siv sib txuas lus, cov khoom siv hluav taws xob tsheb thiab cov khoom siv. Stack-up configuration, txheej suav, cov khoom qib thiab ntawm cov qauv ncaj qha cuam tshuam rau kev ua tau zoo, kev tsim khoom thiab tag nrho cov nqi. Cov kws tsim khoom thiab cov neeg yuav khoom yuav tsum tau txhais cov txheej txheem suav thiab pawg- nce raws li cov kev xav tau ntawm kev ncaj ncees, kev xav tau thiab kev txwv nyiaj txiag, zam dhau - cov lus qhia tshwj xeeb uas ua rau tus nqi tsis tsim nyog.
Qhov project yuav tsum tau Multilayer PCB
Ntau pawg neeg yuav khoom tau txais kev thov rau 4-txheej, 6-txheej lossis txawm tias 12-txheej pawg thawj coj tsis nkag siab tias vim li cas cov txheej txheem suav tau raug xaiv.
Hauv kev xyaum, qhov kev txiav txim siab yuav tsum tau ua raws li kev tsim qauv es tsis yog kev xav.
Lub multilayer PCB feem ntau pom zoo thaum cov khoom xav tau:

- Tswj impedance routing
- Ntau lub zog thiab hauv av dav hlau
- High -ceev teeb liab kis tau tus mob
- Compact board qhov ntev
- Txo EMI thiab suab nrov
Piv txwv li, tus tswj kev lag luam yooj yim tuaj yeem ua haujlwm zoo kawg nkaus ntawm 2-txheej PCB, thaum lub tshuab sib txuas uas muaj cov txheej txheem, nco modules thiab kev sib txuas lus sib txuas yuav xav tau 6 lossis 8 txheej los tswj cov teeb liab kev ncaj ncees.
Kev xaiv cov txheej txheem ntau dhau tuaj yeem ua rau cov nqi tsim khoom tsis tsim nyog, thaum xaiv cov khaubncaws sab nraud povtseg yuav ua rau muaj kev cuam tshuam rau kev tsim thiab teeb meem kev ua haujlwm.
Sib piv 2-Layer thiab Multilayer PCB Designs
Ib qho lus nug ntau los ntawm cov neeg yuav khoom yog seb qhov kev hloov kho dua tshiab los ntawm 2-txheej PCB mus rau ntau txheej tsim tsim nyog rau kev nqis peev ntxiv.
Cov lus teb nyob ntawm daim ntawv thov kev ua tau zoo.

Thaum multilayer PCBs feem ntau raug nqi ntau dua rau kev tsim khoom, lawv feem ntau txo cov nqi tag nrho los ntawm kev tso cai rau cov khoom me me thiab tshem tawm cov qauv tsim.
Ntau cov khoom siv hluav taws xob compact yuav tsis ua tau yam tsis muaj cov txheej txheem multilayer.
Kev tsim khoom nyuaj Cov neeg yuav khoom yuav tsum nkag siab
- Tsis yog txhua tus neeg tsim khoom PCB muab tib lub peev xwm multilayer.
- Raws li txheej suav nce, manufacturing complexity nce ho.
- Ntau cov txheej txheem tseem ceeb txiav txim siab kawg cov khoom zoo.
Txheej txheej sau npe raug
Tag nrho cov txheej txheej conductive yuav tsum ua kom meej meej thaum lamination. Txawm tias me me yuam kev tuaj yeem cuam tshuam rau kev ua haujlwm hluav taws xob thiab qhov raug drilling.
Lamination Control
Multilayer boards tau txais kev siab - cov txheej txheem lamination. Kev tswj cov txheej txheem tsis raug tuaj yeem ua rau delamination, warpage lossis teeb meem kev ntseeg siab.
Qhov Phab Ntsa Kev Ntseeg
Plated los ntawm qhov sib txuas nrog cov khaubncaws sab nraud povtseg. Qhov sib npaug plating thickness yog qhov tseem ceeb rau kev ntev - hluav taws xob kev ntseeg tau.
