Multilayer PCB, txhua txheej HDI PCB
High txheej / txhua txheej HDI chaw tsim tshuaj paus
Lub ntsiab txhais ntawm HDI (High Density lnterconnection) Circuit Court board hais txog Microvia PCB nrog qhov aperture ntawm tsawg dua 6 hli, Lub Qhov Ncauj ntawm qhov tsawg dua 0.25 hli, qhov sib cuag ntom ntom ntawm ntau dua 130 cov ntsiab lus / square teev, kev sib txuas ntau dua. tshaj 117 cov ntsiab lus / square teev, thiab kab dav / qhov sib nrug ntawm tsawg dua 3mi / 3mi.
Kev faib tawm ntawm HDI PCB: 1 txheej, 2 txheej, 3 txheej thiab txhua txheej HDI
1 txheej HDI qauv: 1 + N + 1 (nias ob zaug, laser ib zaug).
2 txheej HDI qauv: 2 + N + 2 (nias 3 zaug, laser ob zaug).
3 txheej HDI qauv: 3 + N + 3 (nias 4 zaug, laser 3 zaug).
Txhua txheej HDI hais txog HDI uas tuaj yeem ua cov txheej txheem laser drilling los ntawm cov tub ntxhais PCB, hauv lwm lo lus, nws txhais tau hais tias yuav tsum tau siv lub laser drilling ua ntej nias.
Qhov zoo ntawm HDI PCB
1. Nws tuaj yeem txo cov nqi PCB. Thaum lub PCB ceev nce mus rau ntau tshaj 8 txheej, nws yog tsim nyob rau hauv txoj kev ntawm HDI thiab nws cov nqi yuav qis dua cov txheej txheem txheej txheem nyuaj.
2. Nce Circulcuit Court ntom los ntawm Interconected Circuit Court Cov laug cam thiab Cheebtsam
3. Muaj txiaj ntsig zoo rau kev siv cov tshuab ntim khoom siab heev
4. Muaj cov khoom siv hluav taws xob zoo dua thiab cov teeb liab raug
5. Kev ntseeg tau zoo dua
6. tuaj yeem txhim kho kev ua haujlwm thermal
7. tuaj yeem txo cov xov tooj cua zaus cuam tshuam, electromagnetic yoj cuam tshuam, thiab electrostatic paug (RFI/EMI/ESD)
8. Txhim khu kev tsim qauv
Qhov sib txawv tseem ceeb ntawm HDI thiab PCB tsis tu ncua
1. HDI muaj qhov ntim me me thiab sib dua
HDI PCB yog ua los ntawm cov tsoos ob-sided PCB ua lub hauv paus, los ntawm kev tsim thiab lamination. Hom kab hluav taws xob no ua los ntawm cov txheej txheem txuas ntxiv tseem hu ua Build-up Multilayer (BUM). Muab piv rau cov rooj tsav xwm niaj hnub, HDI Circuit Court boards muaj qhov zoo xws li lub teeb, nyias, luv thiab me.
Kev sib txuas hluav taws xob ntawm HDI Circuit Board yog ua tiav los ntawm kev siv hluav taws xob los ntawm lub qhov, faus / dig muag los ntawm kev sib txuas, uas yog qhov sib txawv ntawm cov txheej txheem ntau txheej txheej. Micro faus / dig muag ntawm yog dav siv hauv HDI PCBs. HDI siv ncaj qha laser drilling, thaum cov txheej txheem PCBs feem ntau siv cov tshuab drilling, yog li tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab nam piv feem ntau txo.
2. Kev tsim cov txheej txheem ntawm HDI lub ntsiab board
Txoj kev loj hlob siab ntawm HDI PCBs feem ntau yog tshwm sim nyob rau hauv qhov ceev ntawm qhov, circuits, solder pads thiab interlayer thickness.
● Micro los ntawm-qhov: HDI PCBs muaj qhov tsis pom kev thiab lwm qhov kev tsim ntawm micro los ntawm lub qhov, uas feem ntau tshwm sim hauv cov kev xav tau siab ntawm micro qhov tsim tshuab nrog lub qhov pore loj dua 150um, nrog rau cov nqi, kev tsim khoom thiab qhov chaw tswj qhov tseeb. Nyob rau hauv ib txwm muaj ntau txheej Circuit Court boards, tsuas yog dhau-qhov thiab tsis muaj qhov me me faus / qhov muag tsis pom
● Kev kho kom zoo ntawm kab dav / qhov sib txawv: feem ntau tshwm sim hauv cov kev cai nruj zuj zus ntxiv rau cov hlau tsis xws luag thiab hlau nto roughness. Txoj kab dav dav / qhov sib nrug tsis tshaj 76.2um
● High pad ntom: Qhov ceev ntawm cov pob qij txha yog ntau dua 50 / cm2
● Thinning ntawm dielectric thickness: Qhov no feem ntau yog tshwm sim nyob rau hauv cov qauv ntawm interlayer dielectric thickness tsim ntawm 80um thiab hauv qab no, thiab qhov yuav tsum tau rau thickness uniformity yog nce nruj, tshwj xeeb tshaj yog rau high-density PCBs thiab ntim substrates nrog cov yam ntxwv impedance tswj.
3. HDI PCB muaj kev ua tau zoo ntawm hluav taws xob
HDI tuaj yeem tsis tsuas yog miniaturize kawg cov khoom tsim, tab sis kuj ua tau raws li cov qauv siab dua ntawm kev ua haujlwm hluav taws xob thiab kev ua haujlwm zoo ib txhij.
Qhov kev sib txuas ntau ntxiv ntawm HDI tso cai rau kev txhim kho lub teeb liab lub zog thiab txhim kho kev ntseeg tau. Tsis tas li ntawd, HDI PCBs muaj kev txhim kho zoo dua hauv kev txo cov xov tooj cua zaus cuam tshuam, electromagnetic yoj cuam tshuam, electrostatic tawm thiab kub conduction, thiab lwm yam. HDI kuj tau txais tag nrho cov teeb liab txheej txheem tswj (DSP) technology thiab ntau yam patented technologies, uas muaj peev xwm hloov tau. kom loads nyob rau hauv ib tug tag nrho ntau yam thiab muaj zog lub sij hawm luv luv overload muaj peev xwm.
4. HDI PCBs muaj kev xav tau siab heev rau kev faus ntawm/plug qhov
Raws li tuaj yeem pom los ntawm cov saum toj no, ob qho tib si ntawm lub rooj tsav xwm loj thiab kev ua haujlwm hluav taws xob, HDI zoo dua li PCBs zoo tib yam. Txhua lub npib muaj ob sab, thiab sab nraud ntawm HDI, raws li high-end PCB, nws qhov chaw tsim khoom thiab cov txheej txheem nyuaj yog ntau dua li cov PCBs zoo tib yam, thiab tseem muaj ntau yam teeb meem uas yuav tsum tau them nyiaj rau thaum lub sij hawm tsim khoom, tshwj xeeb tshaj yog cov faus ntawm thiab ntsaws qhov.
Tam sim no, qhov tseem ceeb ntawm qhov mob thiab qhov nyuaj hauv HDI ntau lawm thiab kev tsim khoom yog qhov faus ntawm thiab ntsaws qhov. Yog tias HDI faus ntawm / ntsaws qhov tsis ua tiav zoo, cov teeb meem tseem ceeb yuav tshwm sim, suav nrog cov npoo tsis sib xws, qhov nruab nrab tuab tsis sib xws thiab cov poholes ntawm cov ntaub qhwv.
● Lub rooj tsav xwm tsis sib xws thiab cov kab tsis sib xws tuaj yeem ua rau lub puam tshwm sim hauv thaj chaw sunken, ua rau muaj qhov tsis xws luag xws li kab sib txawv thiab tawg.
● Cov yam ntxwv impedance kuj yuav hloov pauv vim qhov tsis sib xws ntawm dielectric thickness, ua rau lub teeb liab tsis ruaj khov
● Cov ntaub qhwv tsis sib xws ua rau tsis zoo tom qab ntim khoom, ua rau kev sib koom ua ke thiab ntau yam khoom poob.
Yog li ntawd, tsis yog txhua lub tuam txhab PCB muaj peev xwm thiab lub zog ua HDI zoo, thiab RICH PCBA tau ua haujlwm hnyav rau qhov no ntau dua 20 xyoo.
Peb tau ua tiav cov txiaj ntsig zoo hauv kev tsim tshwj xeeb xws li high-precision, high-density, high-frequency, high-speed, high TG, carrier plates thiab RF PCB. Peb kuj muaj kev nplua nuj tsim nyob rau hauv cov txheej txheem tshwj xeeb xws li ultra-thick, oversized, tuab tooj liab, high-frequency hybrid siab, tooj liab inlaid blocks, ib nrab qhov, rov qab xyaum, qhov tob-tswj xyaum, kub ntiv tes, high-precision impedance tswj boards , lwm.
