Taw qhia
HDI yog cov ntawv luv rau High-Density Interconnect.Nws yog cov txheej txheem tsim PCB nyuaj.HDI PCB thev naus laus zis tuaj yeem txo cov ntawv luam tawm hauv Circuit Court boards hauv PCB teb.Cov thev naus laus zis tseem muab kev ua haujlwm siab thiab ntau dua ntawm cov xov hlau thiab circuits.
Los ntawm txoj kev, HDI Circuit Court boards yog tsim txawv dua li ib txwm luam Circuit Court boards.
HDI PCBs yog siv los ntawm me me vias, kab thiab qhov chaw.HDI PCBs yog qhov hnyav heev, uas zoo sib xws rau lawv cov miniaturization.
Ntawm qhov tod tes, HDI yog tus cwj pwm los ntawm kev sib kis ntau zaus, tswj tsis tau hluav taws xob, thiab tswj impedance ntawm PCB.Vim lub miniaturization ntawm lub rooj tsavxwm, lub rooj tsavxwm ceev yog siab.
Microvias, dig muag thiab faus vias, kev ua haujlwm siab, cov ntaub ntawv nyias thiab cov kab zoo yog tag nrho cov cim ntawm HDI luam tawm Circuit Board.
Cov engineers yuav tsum muaj kev nkag siab zoo txog kev tsim thiab HDI PCB txheej txheem tsim khoom.Microchips ntawm HDI luam tawm Circuit Board yuav tsum tau saib xyuas tshwj xeeb thoob plaws hauv cov txheej txheem sib dhos, nrog rau kev txawj ntse zoo heev.
Hauv kev tsim qauv zoo li lub laptops, xov tooj ntawm tes, HDI PCBs yog qhov me me thiab qhov hnyav.Vim lawv qhov me me, HDI PCBs kuj tsis tshua muaj kev tawg.
HDI Vias
Vias yog qhov hauv PCB uas yog siv los txuas hluav taws xob sib txawv hauv PCB.Siv ntau cov khaubncaws sab nraud povtseg thiab txuas lawv nrog vias txo PCB loj.Txij li lub hom phiaj tseem ceeb ntawm lub rooj tsavxwm HDI yog txo nws qhov loj, vias yog ib qho tseem ceeb tshaj plaws.Muaj ntau hom los ntawm qhov.
Thla lub viav vias
Nws mus los ntawm tag nrho cov PCB, los ntawm txheej txheej saum npoo mus rau hauv qab txheej, thiab hu ua viav vias.Lub sijhawm no, lawv txuas tag nrho cov txheej txheem ntawm cov ntawv luam tawm Circuit Board.Txawm li cas los xij, vias siv ntau qhov chaw thiab txo qhov chaw tiv thaiv.
dig muagviav
Qhov muag tsis pom vias tsuas yog txuas cov txheej txheej sab hauv mus rau txheej txheej hauv PCB.Tsis tas yuav laum tag nrho PCB.
faus via
faus vias yog siv los txuas cov txheej txheej sab hauv ntawm PCB.faus vias tsis pom los ntawm sab nraud ntawm PCB.
Microviav
Micro vias yog qhov tsawg tshaj plaws ntawm qhov loj me dua 6 mils.Koj yuav tsum siv laser drilling los tsim micro vias.Yog li hauv paus, microvias yog siv rau HDI boards.Qhov no yog vim nws qhov loj me.Txij li thaum koj xav tau cov kev sib xyaw ua ke thiab tsis tuaj yeem nkim chaw hauv HDI pcb, nws yog cov paub qab hau los hloov lwm yam vias nrog Microvias.Tsis tas li ntawd, microvias tsis raug kev txom nyem los ntawm cov teeb meem thermal expansion (CTE) vim lawv cov kav ntev.
stackup
HDI PCB stack-up yog txheej txheej txheej txheej.Tus naj npawb ntawm cov khaubncaws sab nraud povtseg lossis pawg tuaj yeem txiav txim siab raws li qhov xav tau.Txawm li cas los xij, qhov no tuaj yeem yog 8 txheej rau 40 txheej lossis ntau dua.
Tab sis tus naj npawb ntawm cov txheej yog nyob ntawm qhov ntom ntawm cov kab.Multilayer stacking tuaj yeem pab koj txo qis PCB loj.Nws kuj txo cov nqi tsim khoom.
Los ntawm txoj kev, txhawm rau txiav txim siab cov txheej txheem ntawm HDI PCB, koj yuav tsum txiav txim siab qhov loj me thiab cov nets ntawm txhua txheej.Tom qab txheeb xyuas lawv, koj tuaj yeem suav cov txheej txheej tsim nyog rau koj lub rooj tsav xwm HDI.
Lub tswv yim los tsim HDI PCB
1. Precise Cheebtsam xaiv.HDI boards xav tau tus pin siab suav SMDs thiab BGAs me dua 0.65mm.Koj yuav tsum xaiv lawv kom zoo raws li lawv cuam tshuam los ntawm hom, kab dav thiab HDI PCB pawg-up.
2. Koj yuav tsum siv microvias ntawm lub rooj tsavxwm HDI.Qhov no yuav tso cai rau koj kom tau txais ob npaug ntawm qhov chaw ntawm ib qho los yog lwm yam.
3. Cov khoom siv uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig yuav tsum tau siv.Nws yog ib qho tseem ceeb rau manufacturability ntawm cov khoom.
4. Yuav kom tau ib lub tiaj tus PCB nto, koj yuav tsum tau sau lub qhov ntawm lub qhov.
5. Sim xaiv cov ntaub ntawv nrog tus nqi CTE tib yam rau txhua txheej.
6. Ua tib zoo saib xyuas cov thermal tswj.Xyuas kom tseeb tias koj tsim thiab teeb tsa cov txheej txheem uas tuaj yeem tshem tawm cov cua sov kom zoo.
