HDI PCB luam tawm Circuit Board

Product Detail

Beton Hoobkas muab cov kev daws teeb meem rau cov ntim qis / siab-ntim PCB kev tsim khoom ntawm qhov nrawm nrawm. HDI PCB Print Circuit Board yog rau kev tsim kho siab heev nrog rau kev xav tau ntawm aerospace, kev tiv thaiv, kev kho mob, thiab kev lag luam.

Dab tsi yog High Density Interconnects (HDI) board

High Density Interconnects (HDI) board yog txhais raws li ib tug board (PCB) nrog ib tug ntau dua wiring density nyob rau hauv ib chav tsev cheeb tsam tshaj cov pa luam ntawv Circuit Court boards (PCB). Lawv muaj cov kab zoo thiab qhov chaw (<100 µm),="" smaller="" vias=""><150 µm)="" and="" capture="" pads=""><400 µm),="" i/o="">300, and higher connection pad density (>20 pads / cm2) dua li ua haujlwm hauv cov tshuab PCB. HDI board yog siv los txo qhov loj thiab qhov hnyav, nrog rau kev txhim kho hluav taws xob.

Raws li txheej txheej sib txawv, tam sim no DHI pawg thawj coj tau muab faib ua peb hom:

1) HDI PCB (1 ntxiv rau N ntxiv 1)

Nta:

● Haum rau BGA nrog qis I / O suav

● Cov kab zoo, microvia thiab cov cuab yeej sau npe muaj peev xwm ntawm 0.4 hli pob suab

● Cov khoom tsim nyog thiab kev kho deg rau cov txheej txheem tsis muaj txhuas

● Zoo heev mounting stability thiab kev ntseeg tau

● Copper puv ntawm

Daim ntawv thov: Xov tooj ntawm tes, UMPC, MP3 Player, PMP, GPS, Memory Card

2) HDI PCB (2 ntxiv rau N ntxiv 2)

Nta:

● Tsim nyog rau BGA nrog lub pob me me thiab ntau dua I / O suav

● Ua kom txoj kev ceev ceev hauv kev tsim nyuaj

● Nyias board muaj peev xwm

● Cov khoom siv qis dua Dk / Df ua rau cov teeb liab kis tau zoo dua

● Copper puv ntawm

Daim ntawv thov: Xov tooj ntawm tes, PDA, UMPC, Portable game console, DSC, Camcorder

3) ELIC (Txhua Txheej Txheej Txheej)

Nta:

● Txhua txheej ntawm cov qauv ua kom muaj kev ywj pheej tsim

● Copper puv ntawm muab kev ntseeg tau zoo dua

● Cov yam ntxwv zoo tshaj plaws ntawm hluav taws xob

● Cu pob thiab hlau muab tshuaj technologies rau nyias nyias

Daim ntawv thov: Xov tooj ntawm tes, UMPC, MP3, PMP, GPS, daim npav nco.

Qhov Zoo rau siv High Density Interconnects (HDI) board

● Tso cai rau cov neeg tsim khoom siv cov khoom sib txuas ntxiv rau hauv cov laug cam me me vim tias HDI PCBs tuaj yeem muaj nyob rau ntawm ob sab ntawm lub rooj tsavxwm.

● Txo txo ​​qis kev siv hluav taws xob, ua rau lub roj teeb lub neej ntev dua hauv kev tuav tes thiab lwm yam khoom siv roj teeb.

● Ntau cov khoom ruaj khov thiab rugged, tso cai rau kom muaj zog ntxiv thiab txwv perforations

● Txo thermal degradation, elongating lub neej ntawm lub cuab yeej.

● Tso cai rau kev sib kis tau zoo dua thiab muaj zog dua thiab kev suav hauv cov cheeb tsam me thiab tsim cov khoom siv me me xws li smartphones, cov cuab yeej siv dav hlau, cov cuab yeej siv tub rog, thiab cov khoom siv kho mob.

● Sustainability ntawm Dense BGA thiab QFP Pob hauv PCB Tsim

● Yog tias koj siv cov pob khoom me me BGA thiab QFP hauv koj cov qauv tsim thiab kev siv, HDI PCBs muaj kev ntseeg tau ntau dua hauv kev sib kis thaum koj tus qauv PCB tau txais mus rau qhov khoom loj. HDI PCBs tuaj yeem ua kom haum BGA thiab QFP pob ntau dua li qub PCB thev naus laus zis.

● Txo cov cua sov hloov

Kev hloov hluav taws xob txo qis vim tias muaj tsawg dua rau kev tshav kub mus ncig ua ntej nws tuaj yeem khiav ntawm HDI PCB. HDI PCBs kuj raug kev ntxhov siab tsawg vim yog thermal expansion, txuas lub neej ntawm PCB.

● Tswj kev coj ua

Vias tuaj yeem ua tiav nrog cov khoom siv hluav taws xob lossis cov khoom siv tsis zoo los pab txhawb kev sib kis ntawm cov khoom nyob ntawm koj lub rooj tsavxwm tsim.

Kev ua haujlwm kuj tseem txhim kho raws li qhov muag tsis pom vias thiab viav vias-hauv-pad tso cai rau cov khoom sib xyaw ua ke. Thaum cov kis tau tus mob los ntawm cov khoom mus rau cov khoom raug txo qis, lub sij hawm kis tau tus mob thiab kev hla qeeb qeeb, thaum lub teeb liab muaj zog ntxiv.

● Cov qauv me me (thiab me dua) cov qauv

Thaum nws los txog rau txuag chaw, HDIs yog qhov kev xaiv zoo heev vim tias tag nrho cov txheej txheem tuaj yeem txo qis. Piv txwv li, ib txwm 8- txheej los ntawm qhov PCB tuaj yeem hloov tau yooj yim los ntawm 4- txheej HDI ntawm-hauv-pad daws. Qhov no ua rau cov PCBs me me uas muaj cov vias uas muaj ntau dua lossis tsawg dua qhov pom ntawm qhov muag liab qab.

Thaum kawg, siv HDI PCBs tso cai rau kev tsim cov khoom me me, ruaj khov dua, thiab cov khoom siv tau zoo dua uas cov neeg siv khoom xav tau yam tsis muaj kev cuam tshuam rau kev tsim thiab kev ua haujlwm tag nrho.

HDI Structures:

1 ntxiv rau N ntxiv 1 - PCBs muaj 1 "tsim-up" ntawm high-density interconnection txheej.

i plus N plus i (i Greater than or equal to 2) – PCBs muaj 2 los yog ntau tshaj "build-up" ntawm high density interconnection txheej. Microvias ntawm cov khaubncaws sab nraud povtseg tuaj yeem staggered lossis stacked. Copper ntim stacked microvia cov qauv feem ntau pom hauv cov qauv tsim.

Txhua Txheej HDI - Tag nrho cov txheej ntawm PCB yog cov txheej txheem kev sib txuas siab siab uas tso cai rau cov neeg ua haujlwm ntawm txhua txheej ntawm PCB kom sib cuam tshuam nrog cov tooj liab ntim cov txheej txheem microvia ("txhua txheej ntawm"). Qhov no muab cov kev sib txuas txhim khu kev qha rau cov khoom siv sib txuas loj heev, xws li CPU thiab GPU chips siv ntawm cov khoom siv tes.
