Txhua Txheej High Density Interconnected PCB
LUB TSWV YIM TSEEM CEEB NTAWM HDI
HDI sawv cev rau High Density Interconnector, uas yog hom PCB tsim khoom (technology), siv micro blind/faus ntawm thev naus laus zis los ua kom muaj kev faib tawm kab siab. Nws tuaj yeem ua tiav qhov me me, kev ua tau zoo dua thiab cov nqi qis dua. HDI PCB yog kev nrhiav ntawm cov neeg tsim qauv, tas li txhim kho mus rau qhov siab thiab qhov tseeb. Qhov hu ua "siab" tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub tshuab xwb, tab sis kuj txo qhov loj ntawm lub tshuab. High Density Integration (HDI) thev naus laus zis tuaj yeem ua rau kev tsim khoom kawg me dua, thaum ua tau raws li cov qauv siab dua ntawm kev ua tau zoo thiab kev ua haujlwm ntawm hluav taws xob.
HDI PCB feem ntau muaj xws li laser drilling blind via thiab mechanical drilling blind via. Cov thev naus laus zis ntawm kev coj ua ntawm cov txheej sab hauv thiab sab nraud feem ntau ua tiav los ntawm cov txheej txheem xws li through buried via, blind via, stacked qhov, staggered qhov, cross blind/faus via, through holes, blind via filling electroplating, fine wire me me qhov chaw thiab micro qhov hauv lub disc, thiab lwm yam.
Muaj ntau hom HDI PCB: 1 txheej, 2 txheej, 3 txheej, 4 txheej thiab txhua txheej sib txuas.
● Cov qauv ntawm 1 txheej HDI: 1 + N + 1 (nias ob zaug, laser drilling ib zaug).
● Cov qauv ntawm 2 txheej HDI: 2 + N + 2 (nias 3 zaug, laser drilling ob zaug).
● Cov qauv ntawm 3 txheej HDI: 3+N+3 (nias 4 zaug, laser drilling 3 zaug).
● Cov qauv ntawm 4 txheej HDI: 4+N+4 (nias 5 zaug, laser drilling 4 zaug).
Los ntawm cov qauv saum toj no, nws tuaj yeem xaus lus tias laser drilling ib zaug yog 1 txheej HDI, ob zaug yog 2 txheej HDI, thiab lwm yam. Txhua txheej Interconnection tuaj yeem pib laser drilling los ntawm lub rooj tsavxwm tseem ceeb. Hauv lwm lo lus, qhov yuav tsum tau laser drilled ua ntej nias yog txhua txheej HDI.
Lub Tswv Yim Tsim Qauv ntawm HDI
1. Thaum peb ntsib ib qho qauv tsim uas muaj qhov nyob rau hauv thaj chaw BGA ntawm ntau txheej PCB, tab sis vim muaj qhov chaw txwv, peb yuav tsum siv cov BGA pads me me thiab cov qhov me me kom ua tiav kev nkag mus rau hauv tag nrho lub rooj tsavxwm, peb yuav tsum ua li cas? Tam sim no peb xav qhia HDI high precision PCB uas tau hais ntau zaus hauv PCBs raws li hauv qab no.
Cov cuab yeej siv drilling no feem ntau siv rau kev tho PCB. Thaum lub qhov loj ntawm qhov tho tau txog 0.15 hli, tus nqi twb siab heev lawm thiab nyuaj rau txhim kho ntxiv. Txawm li cas los xij, vim muaj qhov chaw tsawg, thaum tsuas yog qhov loj ntawm qhov 0.1 hli xwb thiaj siv tau, lub tswv yim tsim ntawm HDI yog qhov tsim nyog.
2. Kev tho qhov ntawm HDI PCB tsis vam khom kev tho qhov ib txwm muaj lawm, tab sis siv cov thev naus laus zis laser tho qhov (qee zaum kuj hu ua laser board). Qhov loj ntawm qhov tho qhov ntawm HDI feem ntau yog 3-5mil (0.076-0.127mm), qhov dav ntawm kab yog 3-4mil (0.076-0.10mm), qhov loj ntawm cov solder pads tuaj yeem txo qis heev, yog li ntau kab faib tuaj yeem tau txais ib cheeb tsam, ua rau muaj kev sib txuas ceev ceev.
Qhov tshwm sim ntawm HDI thev naus laus zis tau hloov kho thiab txhawb nqa kev txhim kho ntawm PCB kev lag luam, ua rau muaj ntau dua BGA, QFP, thiab lwm yam kom raug teeb tsa rau ntawm HDI PCB. Tam sim no, HDI thev naus laus zis tau siv dav, ntawm cov uas 1 txheej HDI tau siv dav hauv PCB tsim nrog 0.5pitch BGA. Kev txhim kho ntawm HDI thev naus laus zis yog tsav tsheb kev txhim kho ntawm cov thev naus laus zis chip, uas ua rau kev txhim kho thiab kev nce qib ntawm HDI thev naus laus zis.
Niaj hnub no 0.5pitch BGA chips tau maj mam siv los ntawm cov kws tsim qauv, thiab cov pob qij txha ntawm BGA tau maj mam hloov pauv los ntawm qhov chaw nruab nrab hollowed tawm lossis grounded daim ntawv mus rau ib daim ntawv nrog cov teeb liab nkag thiab tso zis ntawm qhov chaw uas xav tau kev txuas hluav taws xob.
3. HDI PCB feem ntau yog tsim los ntawm kev siv txoj kev stacking. Qhov ntau zaus ntawm kev stacking ua tiav, qhov siab dua ntawm qib kev txawj ntse ntawm lub rooj tsavxwm. HDI PCB ib txwm yog stacked ib zaug, thaum cov txheej siab HDI siv ob zaug lossis ntau dua stacking thev naus laus zis, nrog rau cov thev naus laus zis PCB siab heev xws li qhov stacking, qhov puv qhov los ntawm electroplating thiab ncaj qha laser drilling, thiab lwm yam.
HDI PCB zoo rau kev siv cov thev naus laus zis sib dhos siab heev, thiab kev ua haujlwm hluav taws xob thiab qhov tseeb ntawm lub teeb liab siab dua li cov PCB ib txwm muaj. Tsis tas li ntawd xwb, HDI muaj kev txhim kho zoo dua hauv kev cuam tshuam xov tooj cua zaus, kev cuam tshuam ntawm nthwv dej hluav taws xob, kev tso tawm hluav taws xob thiab kev ua kom sov, thiab lwm yam.
Daim Ntawv Thov
HDI PCB muaj ntau yam kev siv hauv kev siv hluav taws xob, xws li:
-Cov Ntaub Ntawv Loj & AI: HDI PCB tuaj yeem txhim kho qhov zoo ntawm lub teeb liab, lub roj teeb lub neej thiab kev koom ua ke ntawm cov xov tooj ntawm tes, thaum txo lawv qhov hnyav thiab tuab.
