HDI PCB yog dab tsi?
HDI (High-Density Interconnect) PCB yog hais txog lub rooj tsav xwm hluav taws xob uas tsim los rau kev ua haujlwm me me thiab siab -kev ua haujlwm nrawm siv cov thev naus laus zis sib txuas. Cov yam ntxwv tseem ceeb muaj xws li:
- Microvias (<6mil) created via laser drilling
- Stacked lossis staggered microvia cov qauv
- Kev them nyiaj yug rau ntawm -hauv- ncoo thiab sau los ntawm kev ua kom tiav
- Sequential lamination rau multilayer stackups
Piv rau cov txheej txheem multilayer PCBs, HDI PCB muaj
Miniaturization
Kev ua haujlwm ntau dua hauv qhov chaw tsawg dua -zoo tagnrho rau cov khoom siv hluav taws xob portable.
High -Speed Performance
Shorter teeb liab txoj kev thiab txo latency.
Txhim khu kev ntseeg
Tsawg dua los ntawm - qhov ua kom lub zog siv zog thiab kev co kuj.
Functional Integration
Txhawb RF, analog -digital hybrid, thiab siab - qauv tsim teeb liab

Tsim Kev Sib Tw hauv HDI PCB Tsim
Txawm hais tias nws qhov zoo, HDI PCB Design nthuav tawm tiag tiag - ntiaj teb kev sib tw engineering:
- Limited board vaj tse thiab siab tivthaiv ntom ntom
- Dense BGA pob khoom nrog cov kiv cua nyuaj- tawm routing
- Dual -sab routing nce teeb liab txoj kev nyuaj
- Me me ntawm qhov ntev xav tau kev ntseeg siab
- Cov khoom siv sib xws thiab thermal stability yuav tsum raug ntsuas ua ntej -
Txhawm rau txo cov kev pheej hmoo ntxov, peb pab neeg koom nrog rau theem ntawm kev tsim kho hdi pawg thawj coj saib - pab nrog kev npaj pob, teeb tsa kev teeb tsa, thiab ntawm kev txhim kho cov qauv kom ntseeg tau tias tsis muaj kev hloov pauv mus rau hdi pcb board tsim thiab tsim khoom.
Precision HDI PCB layout & Stackup Strategy
Qhov zoo ntawm hdi pcb layout yuav tsum ntsuas lub teeb liab kev ncaj ncees, EMI tsub kom, thermal tswj, thiab manufacturability. Nyob rau hauv high density pcb layout, kab dav dav yuav shrink rau 3mil, xav tau impedance tswj thiab interlayer coupling tsom xam.
Lub zog HDI PCB stackup tsim tsim cov caj qaum ntawm lub rooj tsavxwm txhim khu kev qha. Cov kev coj ua zoo tshaj plaws suav nrog:
- Sandwiching siab -cov teeb liab ceev cov txheej txheem ntawm cov dav hlau hauv av kom ruaj khov
- Muab decoupling capacitor ntawm lub hwj chim thiab hauv av txheej kom txo cov suab nrov
- Tuav symmetrical txheej thickness rau mechanical stability
Kev xaiv cov khoom & kev tsim khoom
Cov ntaub ntawv rau HDI PCB yuav tsum ua raws li cov txheej txheem nruj:
- High Tg (iav hloov kub) rau reflow resilience
- Strong copper adhesion (>6 lb/hauv)
- Zoo heev dielectric stability thiab thermal shock kuj
- Compatibility nrog laser drilling thiab microvia filling
- Cov ntaub ntawv muaj xws li PI films, RCC, thiab LD prepregs.
STHL siv cov txheej txheem lamination rau hdi pcb board tsim fabrication, suav nrog:
- Photoresist txheej thiab raug
- Pattern etching thiab tu
- Laser los yog tshuaj los ntawm drilling
- Los ntawm metallization thiab filling
- Multilayer lamination
- Nto tiav thiab kuaj hluav taws xob
DFM Cov Lus Qhia rau Kev Tshaj Tawm Zoo dua
Ua ntej tsim qhov kawg, peb pom zoo kom lees paub:
- Yam tsawg kawg ntawm kab dav / qhov sib nrug
- Yam tsawg kawg ntawm txoj kab uas hla thiab annular nplhaib
- Khoom system thiab impedance tswj muaj peev xwm
- Microvia filling thiab metallization txheej txheem
- Layer suav thiab stackup txwv
- Kev npaj ua ntej txhim kho cov txiaj ntsig, txo tus nqi, thiab ua kom lub sij hawm luv luv.
